Technical Field
[0001] This application belongs to the field of equipment control technology, and in particular relates to a multifunctional device and method for scoliosis rehabilitation. Background Technology
[0002] Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity that occurs during growth and development, including coronal scoliosis, sagittal physiological curvature abnormalities, and vertebral rotation. With the promotion of scoliosis screening programs, a large number of patients with mild to moderate AIS are detected at an early stage. However, non-surgical intervention still faces prominent problems such as low compliance, significant differences in treatment outcomes, and a lack of improvement in flexibility.
[0003] Currently, non-surgical treatments mainly involve bracing and posture training. However, these methods suffer from limitations such as a single treatment model, low functional integration, and insufficient personalized adaptation. Summary of the Invention
[0004] The purpose of this application is to provide a multifunctional device and method for scoliosis rehabilitation, which can realize personalized, multimodal, and synchronous three-dimensional correction of scoliosis. By integrating and coordinating four means of traction, thermotherapy, electrical stimulation and ultrasound, it can improve the flexibility of the spine and balance the function of bilateral muscles, providing an efficient, safe and quantifiable non-surgical rehabilitation solution for clinical practice.
[0005] This application provides a multifunctional device and method for scoliosis rehabilitation, which is implemented as follows:
[0006] A multifunctional device for scoliosis rehabilitation includes: a rehabilitation traction support platform, an array-type electric airbag traction module, a thermomagnetic therapy module, a low-frequency electrical stimulation module, an ultrasound module, and a central control system, wherein: The rehabilitation traction support platform is used to support the target object. It is long and narrow, with its length direction corresponding to the head and tail direction of the target object. The array-type electric airbag traction module is installed inside the rehabilitation traction support platform and is used to perform directional lifting and stretching on the convex side of the thoracolumbar region of the target object. The thermomagnetic therapy module is located inside the rehabilitation traction support platform and above the array-type electric airbag traction module. It is used to activate before the traction treatment begins to pre-treat the paraspinal muscles and fascia tissue of the target object with a combination of heat and magnetic field. The low-frequency electrical stimulation module is located inside the rehabilitation traction support platform in the area corresponding to the paraspinal muscles on the convex side of the target object, and is used to perform electrical stimulation on the paraspinal muscles on the convex side when the target object lies on its convex side with its convex side down. The ultrasound module is installed on the side wall of the rehabilitation traction support platform corresponding to the concave side of the target object, and is used to perform ultrasonic loosening on the concave side of the target object's body surface; The central control system is located in a control box inside the rehabilitation traction support platform and is electrically connected to each module. The system is configured to: acquire imaging data of the target object; generate a three-dimensional traction support surface matching the lateral curvature of the target object and control commands for the array-type electric airbag traction module based on the imaging data; control the thermomagnetic therapy module to perform preprocessing; after preprocessing, activate the array-type electric airbag traction module and coordinately control the low-frequency electrical stimulation module and the ultrasound module to perform convex side traction and electrical stimulation, and concave side ultrasound release in a coordinated manner; during the traction process, adaptively adjust the three-dimensional traction support surface based on the pressure sensor feedback of the array-type electric airbag traction module.
[0007] In one embodiment, the rehabilitation traction support platform is a multi-layer composite structure, comprising, from top to bottom: a contact surface layer, a functional module bearing layer, a traction support layer, and a bottom support layer, wherein: The contact surface layer, made of flexible material, is in direct contact with the target object and is used to provide support; The functional module support layer is located below the contact surface layer and is an integrally formed or combined support structure. It has multiple module installation areas, wiring channels and fixing holes inside for installing array-type electric airbag traction module, thermomagnetic therapy module, low-frequency electrical stimulation module and sensor. The traction support layer is located below the functional module support layer and is used to support the array-type electric airbag traction module and maintain the overall structural stability of the mattress during traction. The bottom support layer, located at the very bottom of the mattress, is a semi-rigid or rigid structure used to provide overall strength support and prevent excessive deformation of the mattress during traction in the side-lying position.
[0008] In one embodiment, the array-type electric airbag traction module includes: multiple segmented strip-type airbag units arranged sequentially along the length of the mattress, with each airbag unit corresponding to a spinal segment, and each airbag unit connected to an air pump and a solenoid valve group through an air passage. The airbag unit is equipped with a pressure sensor to monitor the pressure of each airbag unit in real time and feed it back to the central control system. When the target object lies on its convex side downward, the central control system, according to the generated control commands, differentiates the inflation height and pressure of different strip-type airbag units to form an asymmetric three-dimensional traction support surface that matches the lateral bending shape of the target object, thereby performing directional lifting and stretching on the convex side of the thoracolumbar segment. In one embodiment, the central control system is further configured to perform the following steps to generate a three-dimensional traction support surface that matches the lateral bending morphology of the target object: Based on the imaging data, determine the segmental range and convex direction of the traction effect; Based on the determined segment range and convex side direction, calculate the target traction surface parameters corresponding to the side bending shape of the target object; The target traction surface parameters are discretized into target height parameters and / or target pressure parameters that correspond one-to-one with the segmented strip airbag units; Inflation and deflation are adjusted by controlling the target height parameters and / or target pressure parameters corresponding to each airbag unit to form the initial traction support surface; During traction, feedback signals from the pressure sensors of each airbag unit are received, and each airbag unit is finely adjusted in a closed loop according to the corresponding target height parameters and / or target pressure parameters, so that the actual traction support surface is close to the three-dimensional traction support surface.
[0009] In one embodiment, the central control system is further configured to perform the following steps to calculate target traction surface parameters corresponding to the side bending profile of the target object: Based on the Cobb angle of the principal curve and the position of the apex vertebra measured from the standing full spine X-ray of the target object, a corrective surface distribution function conforming to biomechanics is constructed. The corrective surface distribution function decreases in a Gaussian or parabolic distribution with the apex vertebra as the center. Obtain the vertebral rotation angle sequence Ri from the MRI or CT images of the target object, where Ri represents the vertebral rotation angle of the segment corresponding to the i-th airbag unit; The preset height of the corresponding airbag unit is determined according to the rotation angle Ri. The larger the rotation angle, the higher the preset height of the corresponding airbag unit. In this way, the torque generated by gravity and the reaction force of the airbag pushes the rib forward and drives the vertebral body to rotate. The flexibility index of the target object is calculated using the following formula: Flexibility index = (Standing Cobb angle - Bending Cobb angle) / Standing Cobb angle, and normalized to a value between 0 and 1. Based on the Cobb angle of the main curve, the distribution function of the corrected surface, the vertebral rotation angle sequence, and the flexibility index, the target lift height of each airbag unit is calculated according to the following formula: Hi=K_safe×F_idx×[Wc×C×G(i)+Wr×Ri]; Where Hi represents the target lifting height of the i-th airbag unit, K_safe represents the system's preset safety threshold coefficient, F_idx is the flexibility index, Wc is the lateral curvature correction weight coefficient, representing the basic lifting height corresponding to each degree of Cobb angle, C represents the Cobb angle reading of the main curve, G(i) represents the correction surface distribution function based on the apex position, Wr represents the rotation correction weight coefficient, representing the additional compensation height corresponding to each degree of rotation angle, Wr×Ri represents the preset height, and the array airbag has a total of N airbag units, with index i, where i takes values from 1 to N.
[0010] In one embodiment, the thermomagnetic therapy module includes: a distributed heating unit, a magnetic therapy unit, and a temperature sensor, wherein: The distributed heating unit is used to provide heat to the target treatment area of the target object; The magnetic therapy unit, which is a permanent magnet array or an electromagnet array, is located near the distributed heating unit to form a stable and controllable magnetic field in the target treatment area. The temperature sensor is used to collect temperature information of the contact surface and feed it back to the central control system.
[0011] In one embodiment, the low-frequency electrical stimulation module includes: a flexible electrode unit disposed within the contact surface layer, the flexible electrode unit being arranged along the length direction to cover the paraspinal muscle region on the convex side from the thoracolumbar to the lumbar region; electrode wires and internal wiring channels; and a low-frequency electrical stimulation output unit electrically connected to the central control system; wherein the flexible electrode unit is embedded and fixedly connected to the main body to maintain stable contact with the skin of the target object in a lateral position. During treatment, the device receives control signals from the central control system to limit or interrupt the electrical stimulation output based on the contact status or abnormal signals, and performs an interruption operation in response to the control signals.
[0012] In one embodiment, the ultrasound module includes: a flexible waist belt, the first end of which is fixedly connected to the side wall of the rehabilitation traction support platform corresponding to the thoracolumbar region of the human body, and the second end of which is a free end; at least one ultrasound transducer unit is embedded in the inner side of the flexible waist belt, and the ultrasound transducer unit is attached to the skin of the target object through a coupling layer. When the target object lies on its convex side on the platform, the free end of the flexible waist belt can be wrapped around the outer side of the target object's thoracolumbar region and detachably fixed to the other side wall of the platform, so that the ultrasonic transducer unit covers the concave paravertebral region of the target object, thereby stably applying ultrasonic energy to the concave paravertebral muscles and fascia region.
[0013] In one embodiment, the ultrasound module further includes a tension adjustment structure and a limiting structure, used to limit the pressure of the waist belt on the chest and waist of the target object in the wrapped state. The ultrasound module is electrically connected to the central control system in the main body through the internal wiring channel of the waist belt, and the central control system realizes unified start-stop and parameter control.
[0014] In one embodiment, the central control system includes: a processing unit, a human-machine interaction unit, and a parameter storage unit, wherein: The human-computer interaction unit is used to input information about the target object and its operating mode; The processing unit is used to perform traction surface calculation, module collaborative control, and safety judgment. The parameter storage unit is used to store the preset execution plan and execution process data.
[0015] In one embodiment, the aforementioned multifunctional rehabilitation device further includes: a safety monitoring system, signal-connected to the central control system, for real-time monitoring of safety parameters during execution, and for transmitting the monitored safety parameters to the central control system in real time; the safety monitoring system includes: The airbag pressure monitoring unit is used to monitor the inflation pressure status of each segment of the airbag; A temperature monitoring unit is used to monitor the temperature of the contact surface; An electrical stimulation and ultrasound output monitoring unit is used to monitor whether the output status is abnormal; The contact status monitoring unit is used to determine whether the electrode or ultrasonic transducer is in a valid contact state.
[0016] A method for rehabilitation based on the aforementioned multifunctional device for scoliosis rehabilitation, comprising: Acquire imaging data of the target object; Based on the imaging data, a three-dimensional traction support surface matching the side bending shape of the target object and control commands for the array-type electric airbag traction module are generated. The thermomagnetic therapy module is controlled to perform pretreatment; after the pretreatment is completed, the array-type electric airbag traction module is activated, and the low-frequency electrical stimulation module and ultrasound module are controlled in coordination to enable convex side traction and electrical stimulation, and concave side ultrasound release to be performed in synergy. During traction, the three-dimensional traction support surface is adaptively adjusted based on the pressure sensor feedback from the array-type electric airbag traction module.
[0017] The multifunctional device and method for scoliosis rehabilitation provided in this application integrate multiple rehabilitation methods such as array-type electric airbag traction, thermotherapy, low-frequency electrical stimulation, and ultrasonic release in a single device. The central control system manages and coordinates each module, allowing patients to receive convex side traction, convex side electrical stimulation, concave side ultrasonic release, and full-process thermotherapy in one rehabilitation session without switching between different devices or repeatedly adjusting body position, thus significantly improving rehabilitation efficiency and treatment continuity. The thermotherapy module can be used for pretreatment before treatment and runs continuously throughout the treatment process. It helps to increase local temperature, promote blood circulation, and reduce tissue viscosity, creating a better soft tissue biomechanical environment for subsequent traction, electrical stimulation, and ultrasound intervention, thereby improving the intervention effect and comfort. The array-type electric airbag traction module can achieve independent adjustment based on the patient's Cobb angle, applying directional traction force to the convex side, avoiding the non-targeted problem of existing symmetrical traction, and achieving a combination of spinal correction and flexibility improvement. The low-frequency electrical stimulation module outputs adjustable pulse current to the atrophied muscles on the convex side, promoting muscle fiber recruitment and strength recovery, improving muscle imbalance, and enhancing the active stability of the spine. The ultrasound module acts on the tense or contracted paraspinal muscles and fascia on the concave side, promoting tissue relaxation and elastic recovery through thermal and micro-vibration effects, providing spatial conditions for spinal adjustment. The central control system achieves unified management and coordinated control of the thermotherapy, traction, electrical stimulation, and ultrasound modules. It can automatically operate according to the set treatment sequence and parameters, and adaptively adjust the three-dimensional traction support surface based on sensor feedback, ensuring that the actual traction surface closely approximates the target surface. This intelligent closed-loop control mechanism guarantees both the safety of the treatment process and the consistency and repeatability of each treatment. In other words, it can simultaneously improve spinal flexibility, balance bilateral muscle function, and enhance the effectiveness of braces in a single rehabilitation session, reducing equipment switching and postural adjustments during rehabilitation and improving rehabilitation efficiency.

However, it does not mean that the applicant has used or necessarily used the solution.
[0023] Commonly used devices for improving spinal flexibility in clinical practice include spinal traction beds or postural stretching platforms. These devices typically employ mechanical or electric traction mechanisms, applying traction force to both ends of the patient's trunk to lengthen the longitudinal axis of the spine and relieve paraspinal muscle tension, thereby improving spinal mobility to some extent. While traction beds can improve spinal flexibility to some extent, their application to AIS patients suffers from limitations such as a single therapeutic biomechanical mode, low functional integration, and insufficient personalized adaptation. Another type of device is a low-frequency electrical stimulation combined with ultrasound therapy, primarily used for muscle rehabilitation and soft tissue release. This type of device generally consists of a separate medical low-frequency electrical stimulator and an ultrasound therapy device, which apply different modes of physical therapy to the target muscle groups by placing electrode pads and an ultrasound probe respectively. Although low-frequency electrical stimulation and ultrasound are widely used in muscle rehabilitation, their application in comprehensive interventions for AIS suffers from problems such as fragmented processes, insufficient coordination, and low integration, making it difficult to meet the urgent clinical need for multi-method combination, personalized control, and simultaneous intervention.
[0024] To clarify the description of the solution, the terms "convex side" and "concave side" mentioned in the embodiments of the present invention will first be explained. In the embodiments of the present invention, "convex side" and "concave side" are descriptions relative to the scoliosis morphology of the target object. Taking the target object's standing position as a reference, the side pointed to by the apex of the spinal curvature is the convex side, and the opposite side is the concave side.
[0025] In the treatment process of this invention, the target subject lies on their side on the rehabilitation traction support platform with their convex side facing downwards. In this position, the convex side refers to the side of the target subject's body that is in contact with the platform, i.e., the outer side of the spinal curvature; the concave side refers to the side of the target subject's body that faces the space, i.e., the inner side of the spinal curvature. The target sites of all treatment modules are located based on the convex and concave sides in this position.
[0026] To address the shortcomings of existing spinal flexibility improvement devices, such as limited functionality, fixed traction methods, lack of multimodal collaboration, insufficient differentiated intervention for convex / concave sides, and fragmented treatment processes, this paper presents a multifunctional integrated rehabilitation device to improve spinal flexibility and muscle function balance in adolescent idiopathic scoliosis (AIS) patients. This device can be designed as a mattress, allowing patients to receive spinal flexibility improvement treatment in a lateral decubitus position with the convex side facing down. Specifically, the device... Figure 1 The system may include: a mattress support platform, an array-type electric airbag traction module, a thermotherapy module, a low-frequency electrical stimulation module, an ultrasonic release module, a central control system, and a safety monitoring unit. These components work together to achieve personalized traction, multimodal differentiated intervention, and automated closed-loop control. Specifically: 1) Rehabilitation traction support platform (mattress main structure): The rehabilitation traction support platform serves as the basic load-bearing structure for each functional module. It is long and narrow, with its length corresponding to the patient's head and tail and its width corresponding to the patient's left and right directions.
[0027] This rehabilitation traction support platform can adopt a multi-layered composite structure, comprising, from top to bottom: a contact surface layer, a functional module support layer, a traction support layer, and a bottom support layer. The contact surface layer, made of flexible medical material, is in direct contact with the patient's skin, providing comfortable support and resistance to disinfection and cleaning. The functional module support layer, located below the contact surface layer, is an integrally molded or modular support structure with multiple pre-set module installation areas, wiring channels, and fixing holes for installing thermomagnetic therapy modules, convex-side low-frequency electrical stimulation modules, array-type electric airbag traction modules, and related sensors. The traction support layer, located below the functional module support layer, supports the array-type electric airbag traction module and maintains the overall structural stability of the mattress during traction. The bottom support layer, located at the very bottom of the mattress, is a semi-rigid or rigid structure, providing overall strength support and preventing excessive deformation of the mattress during lateral traction.
[0028] The aforementioned thermomagnetic therapy module can also be a combination of far-infrared heating and pneumatic pulse massage to achieve soft tissue pretreatment and sustained relaxation. The outer material of the mattress support platform can be selected from medical-grade waterproof and breathable fabrics, antibacterial materials, or replaceable cleaning covers, depending on clinical needs, to improve durability and hygiene.
[0029] Furthermore, the edges of the rehabilitation traction support platform can be equipped with anti-roll-off limiting structures or lateral thickening structures to enhance the stability of the patient in the lateral decubitus position.
[0030] 2) Array-type electric airbag traction module: The array-type electric airbag traction module is located inside the rehabilitation traction support platform, in the traction support layer below the contact surface layer, corresponding to the patient's thoracolumbar to lumbar region, and positioned on the side that contacts the mattress when the patient lies on their convex side downwards.
[0031] Specifically, the array-type electric airbag traction module may include: multiple segmented strip-shaped airbag units arranged sequentially along the length of the mattress, each corresponding to a different spinal segment region. Each airbag unit is connected to an air pump and solenoid valve assembly via an air passage. Furthermore, the airbag unit is equipped with a pressure sensor for segmented independent inflation and deflation and pressure monitoring.
[0032] When the patient lies on their convex side with their lower side down, the inflation height and pressure of different strip-type airbag units are differentially controlled to create an asymmetrical three-dimensional traction support surface on the mattress contact surface. This provides directional lifting and stretching of the convex thoracolumbar segment, improving spinal flexibility and providing spatial conditions for orthopedic correction. The phrase "providing spatial conditions for orthopedic correction" in this embodiment refers to the specific physiological state formed in the spine and related paravertebral soft tissues of the target patient during traction, achieved through the directional lifting and stretching of the convex thoracolumbar segment by the array-type electric airbag modules, which is conducive to subsequent orthopedic operations. This specific physiological state includes one or more of the following measurable physiological changes: 1. Mechanical widening of the intervertebral space. Specifically, by applying continuous traction to the convex vertebra and its appendages, the intervertebral space on the concave side is mechanically expanded, reducing the intradiscal pressure and thus providing the necessary physical space for vertebral displacement and repositioning.
[0033] 2. Viscoelastic relaxation of paraspinal muscles and fascia. Specifically, under the synergistic effect of the pretreatment of the thermomagnetic therapy module, the temperature of soft tissue increases and local blood circulation improves. The directional stretching of the airbag promotes stress relaxation and creep of the paraspinal muscles and thoracolumbar fascia on the convex side, which have been in a state of contracture for a long time. That is, the soft tissue gradually lengthens and the tension decreases under constant stretching, thereby relieving its mechanical restraint on the vertebral body.
[0034] 3. Micro-mobilization and release of the costovertebral joint. Specifically, for scoliosis patients with vertebral rotation, the ribs on the convex side are pulled posteriorly and towards the midline due to posterior muscle contracture, resulting in joint locking. The directional lifting of the airbag acts on the costal angle, generating forward and outward thrust, causing a slight relative displacement of the costovertebral joint, releasing the joint locking state, and paving the way for subsequent reversal of vertebral rotation and elimination of bony restrictions through electrical stimulation or ultrasound.
[0035] 4. Redistribution of asymmetric stress. Specifically, by forming an asymmetric three-dimensional traction support surface, the abnormal compressive stress originally concentrated on the concave vertebral endplate is transferred to the convex structure, making the overall stress environment of the spine tend to be balanced, thereby creating a low-stress-resistance mechanical environment for the application of orthopedic force.
[0036] By establishing the aforementioned "spatial conditions," subsequent low-frequency electrical stimulation (for the convex side) and ultrasonic release (for the concave side) can be performed in a physiological state where the tissue has been released and the space has been opened, avoiding the pain and soft tissue damage that may be induced by antagonistic mechanical traction, and significantly improving the efficiency of orthopedic surgery and the safety of treatment.
[0037] During use, the central control system receives the patient's imaging data, which includes at least the Cobb angle of the main curve, the position of the apex vertebra, the positions of the upper and lower vertebrae, and vertebral rotation-related indicators. Based on the above imaging data, the control system determines the segmental range and convex direction of the traction application, and calculates the corresponding target traction surface parameters accordingly.
[0038] The aforementioned target traction surface is discretized into target height or target pressure parameters that correspond one-to-one with the segmented strip airbag units. Each airbag unit adjusts its inflation and deflation according to the corresponding parameters. During traction, the central control system combines airbag pressure feedback to perform closed-loop fine-tuning of the output of each segmented strip, so that the actual traction support surface is consistent with or close to the target three-dimensional surface, thereby achieving individualized and precise traction for coronal scoliosis and associated rotational deformities in AIS patients.
[0039] Specifically, in implementation, the central control system can calculate the target working state of each airbag unit in the array-type electric airbag traction module based on a vector synthesis algorithm of multi-source physiological parameters, so as to simultaneously improve coronal lateral convexity and horizontal rotation in three-dimensional space, and achieve personalized adaptation according to the soft tissue conditions of the target object.
[0040] Suppose that the array airbag has N units, indexed as i (from 1 to N). For the airbag unit numbered i, its target lift height Hi can be calculated according to the following steps: Step S1: Construct the coronal plane correction benchmark.
[0041] Based on the Cobb angle (denoted as C) of the main curve and the position of the apex vertebra (denoted as i_apex) measured from the standing full-spine X-ray of the target subject, a biomechanically compliant correction surface distribution function G(i) is constructed. This distribution function decreases in a Gaussian or parabolic manner with the apex vertebra as the center, ensuring that the maximum corrective force acts at the apex of the lateral curve and avoiding reverse shear force on the end vertebrae.
[0042] Step S2: Introduce a horizontal plane for rotation compensation.
[0043] The system acquires a sequence of vertebral rotation angles (denoted as Ri, e.g., Nash-Moe grading or Aaro-Dahlborn measurement angles) from MRI or CT images of the target subject. Considering that in a lateral decubitus position with the convex side down, the posterior rib bulge caused by vertebral rotation will contact the airbag, the system converts the rotation angle Ri into an additional vertical thrust component. The larger the rotation angle, the higher the preset height of the airbag in that segment. Utilizing the torque generated by gravity and the airbag's reaction force, the system pushes the ribs forward, thereby causing the vertebral body to rotate.
[0044] Step S3: Adaptive weighting of flexibility.
[0045] Introduce the flexibility index of the target object (denoted as F_idx). In one embodiment, the flexibility index can be calculated according to the following formula: F_idx = (Standing Cobb angle - Bending Cobb angle) / Standing Cobb angle, and normalized to a value between 0 and 1. Use F_idx as a global gain coefficient to scale the theoretical correction height calculated above: (1) When F_idx is high (spinal flexibility), the system outputs a correction height close to the theoretical maximum value in order to pursue the maximum correction rate; (2) When F_idx is low (spinal stiffness), the system automatically reduces the output height to prevent muscle strain or pain caused by forced stretching exceeding the elastic limit of soft tissue.
[0046] Step S4: Final instruction generation.
[0047] The central control system generates control commands for each airbag based on the following linear formula: Hi=K_safe×F_idx×[Wc×C×G(i)+Wr×Ri]; Where Hi represents the target lift height of the i-th airbag unit (unit: mm), K_safe is the system preset safety threshold coefficient (constant), F_idx is the flexibility index (value from 0 to 1), Wc is the lateral curvature correction weight coefficient, representing the basic lift height corresponding to each degree of Cobb angle, C represents the Cobb angle reading of the main curve, G(i) represents the distribution function value based on the apical vertebra position, Wr represents the rotation correction weight coefficient, representing the additional compensation height corresponding to each degree of rotation angle, and Ri represents the vertebral rotation angle of the segment corresponding to the i-th airbag.
[0048] By determining the target lifting height of each airbag in this way, the airbag array can form an asymmetric three-dimensional traction surface that conforms to the lateral bending shape (the Cobb angle determines the peak position), compensates for rotational distortion (the rotation angle determines local fine-tuning), and adapts to tissue elasticity (flexibility determines the overall amplitude).
[0049] The aforementioned array-type electric airbag traction module can also be a mechanical lifting support structure or a hydraulically driven support unit to achieve precise adjustment of local height and tilt angle.
[0050] 3) Warm magnetic therapy module: The thermomagnetic therapy module is located inside the rehabilitation traction support platform, in the functional module support layer below the contact surface layer, corresponding to the patient's thoracolumbar and lumbar regions, and is located above and adjacent to the array-type electric airbag traction module.
[0051] Specifically, the thermo-magnetic therapy module may include: a distributed heating unit, a magnetic therapy unit, and a temperature sensor. The distributed heating unit provides a constant or adjustable heating effect to the target treatment area. The magnetic therapy unit, an array of permanent magnets or electromagnets, is located adjacent to the heating unit to create a stable or controllable magnetic field in the target area. The temperature sensor collects temperature information from the mattress contact surface and feeds it back to the central control system. Each heating unit and magnetic therapy unit is electrically connected to the central control system via internal wiring channels within the mattress.
[0052] During treatment, the thermomagnetic therapy module can be activated before traction therapy begins to pre-treat the paraspinal muscles and fascia with a combination of heat and magnetic field. During subsequent array-type airbag traction, low-frequency electrical stimulation, and concave ultrasound therapy, the thermomagnetic therapy module can continue to operate to maintain the local tissues in a physiological state conducive to stretching and relaxation.
[0053] By increasing local tissue temperature and improving blood circulation through the effect of heat, and combined with the regulatory effect of magnetic field on the microcirculation and metabolic state of soft tissue, the thermomagnetic therapy module can reduce the viscosity of paraspinal muscles and fascia, providing good tissue conditions for three-dimensional traction, electrical stimulation and ultrasound therapy, thereby improving the overall comfort and synergistic effect of treatment.
[0054] 4) Low-frequency electrical stimulation module: The low-frequency electrical stimulation module is located in the treatment area on the contact side of the rehabilitation traction support platform, below the mattress contact surface, corresponding to the paraspinal muscle area on the convex side of the patient. It is used to perform electrical stimulation treatment on the paraspinal muscles on the convex side when the patient lies on their convex side with their convex side facing down.
[0055] The low-frequency electrical stimulation module may include: a flexible electrode unit disposed within the contact surface layer of the mattress, the electrode unit being arranged along the length of the mattress to cover the paraspinal muscle region on the convex side from the thoracolumbar to the lumbar region; electrode leads and wiring channels within the mattress; and a low-frequency electrical stimulation output unit electrically connected to a central control system. The flexible electrode unit can be embedded and fixedly connected to the mattress body to maintain stable contact with the patient's skin in a side-lying position.
[0056] The aforementioned low-frequency electrical stimulation module can also be a medium-frequency electrical stimulation or interference current stimulation device to meet the muscle stimulation needs and comfort requirements of different patients.
[0057] The aforementioned low-frequency electrical stimulation module can be uniformly controlled by the central control system. Its stimulation intensity, frequency, and working sequence are set in conjunction with the array-type electric airbag traction module and the thermomagnetic therapy module. During treatment, the central control system can limit or interrupt the electrical stimulation output based on the contact status or abnormal signals to ensure the safety and repeatability of the treatment.
[0058] Based on the traction support surface formed by the array-type electric airbag traction module, the low-frequency electrical stimulation module outputs low-frequency pulse current to the paraspinal muscles on the convex side to induce rhythmic contraction of the paraspinal muscles on the convex side, thereby promoting muscle fiber recruitment, improving muscle force distribution and enhancing the active stability of the spine.
[0059] 5) Flexible waistband-style concave ultrasound therapy module: like Figure 1 As shown, the ultrasound module adopts a flexible waistband structure. Specifically, a flexible waistband is fixedly connected to the main body of the rehabilitation traction support platform on the non-contact side (i.e., the side wall of the rehabilitation traction support platform) corresponding to the concave side of the target object.
[0060] The first end of the flexible waist belt is fixedly installed on the side wall of the rehabilitation traction support platform corresponding to the thoracolumbar region of the human body, while the second end is free. The flexible waist belt is an integral part of the rehabilitation traction support platform and is not used independently. At least one ultrasonic transducer unit is embedded on the inner surface of the flexible waist belt, corresponding to the concave side of the paraspinal muscles in the thoracolumbar region of the target object. The ultrasonic transducer unit is attached to the skin of the target object through a coupling layer to ensure effective transmission of ultrasonic energy.
[0061] Furthermore, the ultrasonic transducer unit is electrically connected to the central control system within the platform body via wires embedded in the flexible belt. The central control system then uniformly controls the start / stop, output power, and operating sequence of the ultrasonic module.
[0062] With the target subject lying on their side on the platform with their convex side down, the free end of the flexible waist belt is wrapped around the target subject's thoracolumbar region from the side wall of the platform and detachably fixed to the other side wall of the platform, so that the flexible waist belt covers the concave side of the target subject. At this time, the ultrasonic transducer unit embedded in the inner side of the waist belt is closely attached to the paraspinal muscles and fascia region of the target subject on the concave side through the coupling layer, thereby stably and effectively applying ultrasonic energy to this area to achieve ultrasonic release therapy on the concave side tissues.
[0063] The aforementioned flexible waistband concave ultrasound therapy module can also be equipped with tension adjustment and limiting structures to limit the pressure of the waistband on the patient's chest and waist when it is wrapped, so as to avoid causing pressure or discomfort to the patient; the ultrasound transducer is electrically connected to the central control system in the mattress body through the internal wiring channel of the waistband, and the central control system realizes unified start-stop and parameter control.
[0064] During the treatment, the flexible waist belt concave side ultrasound therapy module works in conjunction with the array-type electric airbag traction module, the thermomagnetic therapy module and the convex side low-frequency electrical stimulation module, so that the patient can receive convex side traction and muscle activation, as well as concave side ultrasound release in the lateral decubitus position, thereby achieving comprehensive intervention for three-dimensional scoliosis.
[0065] The aforementioned ultrasonic release module can also be a radiofrequency thermotherapy or shockwave therapy unit to achieve the functions of myofascial release and tissue elasticity improvement.
[0066] The above structural design achieves the following beneficial effects: First, the ultrasound module and its connecting structure are located on the non-contact side (side wall) of the platform, avoiding pressure from the patient's weight and ensuring the stability and service life of the structure.
[0067] Secondly, the ultrasound module is fixed to the side wall, and when using it, you only need to wrap the belt around your body to fit the concave side, without having to take the probe out and put it in separately, which simplifies the operation process.
[0068] Third, the tension adjustment and limiting structure allows the waist belt's fitting pressure to be adjusted and controlled, improving the comfort and safety of the treatment.
[0069] Fourth, the ultrasound module works in tandem with the airbag traction and electrical stimulation modules in the same position, enabling synchronous and differentiated treatment of the convex and concave sides of scoliosis, thus improving the overall treatment efficiency. Fifth, the ultrasound module can be replaced with a radiofrequency thermotherapy or shockwave therapy unit, providing a variety of treatment options for different indications or patient preferences.
[0070] 6) Central control and security monitoring system: The central control system is located inside the rehabilitation traction support platform or in a control box integrated with the mattress body, serving as the core control unit of the entire rehabilitation therapy device. The central control system is electrically connected to the array-type electric airbag traction module, the thermomagnetic therapy module, the convex side low-frequency electrical stimulation module, and the flexible waist belt-type concave side ultrasound therapy module, and is used to uniformly control and coordinate the start / stop sequence, working status, and output parameters of each module.
[0071] The aforementioned central control system may include: a processing unit, a human-machine interaction unit, and a parameter storage unit. The human-machine interaction unit is used to input patient-related information and treatment modes, the processing unit is used to perform traction surface calculations, module collaborative control, and safety judgments, and the parameter storage unit is used to store preset treatment plans and treatment process data.
[0072] The aforementioned central control system can be controlled and manage data based on a wired touch panel, wireless remote control, or mobile terminal APP, and can be combined with a cloud platform for treatment data storage and efficacy analysis.
[0073] During treatment, the central control system generates corresponding target traction surface parameters for the array-type electric airbag traction module based on the input patient imaging data and preset treatment modes. It also simultaneously controls the working sequence of the thermomagnetic therapy, low-frequency electrical stimulation, and concave ultrasound therapy modules, ensuring synergistic effects across all modules during the same treatment process. All treatment modules operate under the unified scheduling of the central control system, avoiding inconsistencies in treatment rhythms or conflicting effects caused by independent control, thus forming a comprehensive intervention process for the three-dimensional deformity of scoliosis.
[0074] Specifically, the central control system is the core of the invention, and is electrically connected to the array-type electric airbag traction module, the thermomagnetic therapy module, the low-frequency electrical stimulation module and the ultrasound module, respectively, to realize centralized control and coordinated scheduling of multiple modules.
[0075] Before treatment begins, the central control system first activates the thermomagnetic therapy module, controlling it to perform a pre-set pretreatment combining heat and magnetic fields for a predetermined duration. This stage aims to raise the temperature of the paraspinal muscles and fascia tissues of the target individual, improve local blood circulation, and bring the soft tissues to a suitable state of relaxation, creating conditions for subsequent traction.
[0076] Simultaneously, the system acquires individualized imaging data of the target individual. This imaging data includes at least the Cobb angle of the principal curve, the position of the apex vertebra, and the positions of the superior and inferior vertebrae measured from a standing full-spine X-ray, and optionally, a sequence of vertebral rotation angles from MRI or CT images. This data can be obtained through import from external devices, manual input, or integration with the hospital's information system.
[0077] Based on the acquired imaging data, the central control system calculates the target traction surface parameters that match the side bending morphology of the target object. The specific steps are as follows: (1) Determine the segment range and convex direction of the traction action.
[0078] Based on the Cobb angle of the main curve and the positions of the upper and lower vertebrae in the imaging data, the range of spinal segments requiring traction (e.g., T4-L4) is determined, and the direction of the convex side is determined according to the direction of the main curve (left or right convexity). This step ensures that the traction force can be applied precisely to the lateral curvature segment, avoiding unnecessary interference with non-lesion areas.
[0079] (2) Calculate the target traction surface parameters.
[0080] Based on the Cobb angle of the main curve, the position of the apex vertebra, and vertebral rotation indices, a biomechanically conforming orthopedic surface distribution function is constructed. The target traction surface parameters include the required airbag lift height and pressure value for each segment, and their distribution decreases in a Gaussian or parabolic manner centered on the apex vertebra to simulate physiological orthopedic force transmission.
[0081] (3) Discretize into independent control commands for each partition.
[0082] The continuous target traction surface parameters are discretized into target height parameters and / or target pressure parameters that correspond one-to-one with the segmented strip-type airbag units in the array-type electric airbag traction module. Each airbag unit is independently inflated and deflated according to the parameters of its corresponding segment, thereby forming an asymmetric three-dimensional traction support surface.
[0083] As a preferred embodiment, the specific calculation of the target traction surface parameters can be performed using the following biomechanical model: First, based on the Cobb angle of the main curve and the position of the apex vertebra measured from the standing full-spine X-ray of the target object, a biomechanical correction surface distribution function G(i) is constructed, where G(i) decreases in a Gaussian or parabolic distribution with the apex vertebra as the center, indicating the law that the traction force gradually decreases from the apex vertebra to both ends.
[0084] Secondly, the preset height of the corresponding airbag unit is determined according to the rotation angle Ri. The larger the rotation angle, the higher the preset height of the corresponding airbag unit. In this way, the torque generated by gravity and the reaction force of the airbag pushes the rib forward and drives the vertebral body to rotate.
[0085] Then, calculate the flexibility index F_idx of the target object according to the following formula: F_idx = (Standing Cobb angle - Bending Cobb angle) / Standing Cobb angle, normalized to a value between 0 and 1. The flexibility index reflects the flexibility of the spine and is used to adjust traction intensity to avoid injury.
[0086] Finally, based on the Cobb angle C of the main curve, the distribution function G(i) of the corrected surface, the vertebral rotation angle sequence Ri, and the flexibility index F_idx, the target lift height Hi of each airbag unit is calculated according to the following formula: Hi=K_safe×F_idx×[Wc×C×G(i)+Wr×Ri] Wherein, Hi represents the target lifting height of the i-th airbag unit; K_safe represents the system's preset safety threshold coefficient, used to ensure that the lifting height does not exceed the biomechanical safety range; F_idx is the flexibility index, used to dynamically adjust the traction intensity according to the flexibility of the patient's spine; Wc is the scoliosis correction weight coefficient, representing the basic lifting height corresponding to each degree of Cobb angle; C represents the Cobb angle reading of the main curve; G(i) represents the correction surface distribution function based on the apical vertebra position; Wr is the rotation correction weight coefficient, representing the additional compensation height corresponding to each degree of rotation angle; Ri represents the rotation angle of the vertebral body of the segment corresponding to the i-th airbag unit, and Wr×Ri represents the preset height; the array airbag has a total of N airbag units, and the index i takes values from 1 to N.
[0087] The method for determining the scoliosis correction weight coefficient Wc and the rotation correction weight coefficient Wr can be as follows: Based on finite element biomechanical analysis of multiple scoliosis patient samples, the relationship between vertebral displacement and stress under different weight ratios is simulated to achieve the maximum correction rate with minimum intervertebral disc pressure. The range of values for Wc and Wr is obtained through regression analysis. For example, Wc can be set to 0.5~2.0 mm / °, and Wr can be set to 0.2~1.0 mm / °.
[0088] The method for determining the full threshold coefficient K_safe is as follows: based on medical device safety standards, combined with the human body pressure distribution safety threshold (usually ≤32mmHg) and the maximum safe air pressure of the airbag, the baseline value of K_safe is calibrated to be 0.8~1.2 through pressure-altitude conversion test, and this value can be linearly interpolated according to the patient's body mass index (BMI).
[0089] The correction surface distribution function G(i) is used to rationally distribute the basic correction force corresponding to the Cobb angle of the main curve to each segment, ensuring that the maximum correction force acts on the apex vertebra while smoothly transitioning to both ends to avoid abnormal shear force on the end vertebrae. Here, i is the airbag unit index (i=1,2,…,N), and i0 is the airbag unit index corresponding to the apex vertebra. G(i) decreases in a Gaussian or parabolic distribution centered on the apex vertebra, reaching a maximum value of 1 when i=i0, and gradually decaying to 0 as i moves further away from i0.
[0090] As a preferred implementation method, the specific method for determining G(i) is as follows: 1. Gaussian distribution form: G(i) = exp(-(i-i0)² / 2σ²), where the standard deviation σ is dynamically determined based on the number of segments involved in the main curve (i.e. the number of vertebrae between the upper and lower ends). The more segments involved, the larger the value of σ, to ensure that the corrective force decreases smoothly from the top vertebra to both ends. 2. Parabolic distribution form: G(i) = 1 - [(i-i0) / L]², where L is the half-peak width, which is also dynamically determined based on the number of affected segments. Sure.
[0091] The central control system coordinates the control of each module according to a preset recovery sequence. The specific control flow is as follows: Pretreatment stage: The thermomagnetic therapy module is activated first to pretreat the paraspinal muscles and fascia tissues of the target object with a combination of heat and magnetic field to achieve a relaxed state.
[0092] Main treatment phase: After pretreatment, the system synchronously or sequentially starts the following modules: Array-type electric airbag traction module: Based on the generated independent control commands for each zone, it controls the independent inflation and deflation of each airbag unit to form an asymmetrical three-dimensional traction support surface, which performs directional lifting and stretching on the convex side of the thoracolumbar region.
[0093] Low-frequency electrical stimulation module: When the target object is lying on its side with its convex side facing down, electrical stimulation is applied to the paraspinal muscles on the convex side to activate the relaxed muscles.
[0094] Ultrasound module: Under the coverage of a flexible waist belt, ultrasonic release is performed on the concave paraspinal muscles and fascia area.
[0095] During traction, the central control system, in conjunction with feedback signals from the pressure sensors built into each airbag unit, performs closed-loop fine-tuning of the target height and / or target pressure parameters for each airbag unit. This ensures that the actual traction support surface closely matches the three-dimensional traction support surface of the target object's lateral bending shape. Specifically, the system monitors the actual airbag pressure in real time and compares it with the target pressure parameters, dynamically adjusting the on / off state of the solenoid valves using a PID control algorithm. If the pressure of a particular airbag unit deviates from the preset range, the system will automatically compensate and adjust to ensure the accuracy and stability of the traction force distribution.
[0096] Meanwhile, the system also receives temperature sensors from the thermomagnetic therapy module and electrode contact status signals from the low-frequency electrical stimulation module. Once an abnormality is detected (such as excessively high temperature or poor electrode contact), the output of the corresponding module will be immediately interrupted to ensure treatment safety.
[0097] Through the aforementioned collaborative control mechanism, each treatment module operates under the unified scheduling of the central control system, avoiding inconsistencies in treatment rhythms or conflicts of action caused by independent control. This achieves the following technical effects: First, pre-treatment with heat precedes traction, conforming to the physiological principle of tissue "softening before stretching." Second, both air-cushion traction and electrical stimulation act on the convex side, while ultrasound acts on the concave side, achieving synchronous and differentiated intervention for three-dimensional scoliosis deformities. Third, personalized parameter generation and real-time closed-loop feedback based on imaging data ensure the precision and safety of the treatment.
[0098] Through unified scheduling and coordinated control of the central control system, the multifunctional device of this invention integrates multiple previously independent physical therapy methods into an organic whole, forming a comprehensive intervention plan for three-dimensional scoliosis deformity, significantly improving the accuracy, safety, and effectiveness of treatment. Specifically: First, by adjusting the weighted coefficients Wc for scoliosis correction and Wr for rotation correction, decoupled control of coronal scoliosis and transverse rotation is achieved, automatically matching the optimal lifting force ratio according to the patient's specific scoliosis type. Second, by introducing the safety threshold coefficient K_safe and the flexibility index F_idx, the system can automatically limit the maximum lifting height according to the stiffness of the patient's spine, preventing excessive stress on stiff spines that could lead to injury, thus achieving intelligent overload protection. Third, based on the Gaussian or parabolic distribution of the correction surface distribution function G(i), the lifting force naturally decays from the apex to both ends, simulating physiological changes in spinal curvature, avoiding abnormal shear forces at the end vertebrae, and improving treatment comfort and biomechanical compatibility. Fourth, the above formula provides doctors with a quantitative tool. Doctors can input imaging data before treatment, and the system can predict the theoretical correction range of this treatment, which is convenient for developing a step-by-step rehabilitation plan.
[0099] The safety monitoring system is connected to the central control system to monitor key safety parameters in real time during treatment. Specifically, the safety monitoring system may include one or more of the following: an airbag pressure monitoring unit to monitor the inflation pressure of each segment of the airbag; a temperature monitoring unit to monitor the temperature of the mattress contact surface; an electrical stimulation and ultrasound output monitoring unit to monitor whether the output status is abnormal; and a contact status monitoring unit to determine whether the electrodes or ultrasound transducers are in effective contact.
[0100] When the safety monitoring system detects that the airbag pressure, temperature, or treatment output parameters exceed the preset safety threshold, the central control system can perform safety interlock operations such as limit adjustment, zone shutdown, or overall shutdown of the corresponding treatment module to avoid causing discomfort or potential risks to the patient.
[0101] Through the coordinated operation of the central control system and the safety monitoring system, unified control and closed-loop safety management of multiple treatment modules are achieved, ensuring the safety, stability and repeatability of the treatment process.
[0102] Furthermore, to address the issue of body stability during traction and treatment in the lateral decubitus position, preventing positional slippage during airbag lifting or body twisting, and ensuring comfort during prolonged treatment, a lateral decubitus adaptive flexible fixation airbag module was also incorporated in this case. This module can be positioned on both sides of the thoracolumbar region of the rehabilitation traction support platform and consists of a C-shaped encircling airbag group (or separate anterior and posterior airbags). When the target patient lies on their convex side facing down, the airbag group inflates and clamps the patient from the chest and abdomen (anterior) and back (posterior) sides, respectively.
[0103] To allow for free and comfortable positioning of the patient's upper arm, the fixation module can employ a limb passageway, which may include: Segmented clamping structure: The fixation airbag is not inflated as a whole in the longitudinal direction, but is divided into an "axillary support segment" and a "lumbar fixation segment". Among them, the lumbar fixation segment is inflated with higher pressure to fit tightly against the patient's chest and back, so as to provide lateral support against the traction reaction force; Arm passage area: The front and rear airbags are designed with recessed U-shaped channels or flexible through holes corresponding to the patient's shoulder and armpit.
[0104] The height and width of this limb passageway can be ergonomically designed to allow the target patient's upper arm (i.e., the arm not in contact with the bed surface) to naturally extend forward or bend and pass through the clamping range of the airbag. The edges of the passageway are made of highly elastic, flexible, and skin-friendly materials (such as memory foam wrapped in Lycra fabric) to ensure that the airbag will not compress the passing arm when it inflates and clamps the torso, avoiding the compression of the axillary nerve plexus and blood vessels by existing fixation straps. In practice, the fixation airbag is connected to a central control system. When the array-type electric airbag traction module at the bottom performs a lifting operation, the lateral fixation airbag automatically increases the medial thrust to dynamically lock the patient's thoracic and lumbar spine position, causing the spine to produce the expected scoliosis correction deformation, rather than turning into a complete body roll. When the treatment is over or the patient needs to adjust their arm position, the passageway can be instantly expanded using a one-button decompression function to facilitate limb movement.
[0105] In the example above, a single device integrates multiple rehabilitation therapies, including array-type electric airbag traction, thermotherapy, low-frequency electrical stimulation, and ultrasonic release, forming a personalized, multimodal, and synchronized spinal flexibility improvement program. The thermotherapy module operates for 20 minutes before treatment as a pretreatment phase and continues throughout the treatment process, helping to raise local temperature, promote blood circulation, and reduce tissue viscosity, creating a better soft tissue biomechanical environment for subsequent traction, electrical stimulation, and ultrasound intervention, thereby improving intervention effectiveness and comfort. The array-type electric airbag traction module can achieve independent zone adjustment and personalized tilt setting based on the patient's Cobb angle, applying directional traction force to the convex side, avoiding the non-targeted problems of existing symmetrical traction, and achieving a combination of spinal correction and flexibility improvement. The low-frequency electrical stimulation module outputs adjustable pulsed current to atrophied muscles on the convex side, promoting muscle fiber recruitment and strength recovery, improving muscle imbalance, and enhancing the active stability of the spine. The ultrasonic release module acts on the concave side of the paraspinal muscles and fascia that are tense or contracted, promoting tissue release and elasticity recovery through thermal and micro-vibration effects, thus providing space for spinal adjustment. The central control system achieves unified management and coordinated control of the thermotherapy, traction, electrical stimulation, and ultrasound modules. It can automatically operate according to the set treatment sequence and parameters, and adjust the output in real time based on sensor feedback, ensuring the safety and repeatability of the treatment.
[0106] Through the synergistic effects described above, spinal flexibility can be improved, bilateral muscle function can be balanced, and the effects of braces or preoperative correction can be enhanced in a single treatment. This reduces equipment switching and postural adjustments during treatment, improves patient compliance and rehabilitation efficiency, and has significant clinical application value and potential for promotion.
[0107] The following are some specific user examples: Example 1: Flexibility improvement treatment plan for patients with moderate AIS: Patient Information: Gender / Age: Female, 12 years old; Diagnosis: Adolescent idiopathic scoliosis, Cobb angle 25° (thoracolumbar segment); Clinical features: mild atrophy of the paraspinal muscles on the convex side and significant tension of the fascia on the concave side; no prior surgical or bracing treatment.
[0108] Treatment device setup: Airbag module: Based on the input Cobb angle, the central control system automatically calculates the traction tilt angle to be 15° and selects the airbag group in the convex side waist area for zonal inflation.
[0109] Thermotherapy module: heating target temperature 40℃, vibration frequency 20Hz.
[0110] Low-frequency electrical stimulation module (convex side): current intensity 20mA, frequency 50Hz, pulse width 300μs, working mode is intermittent output with 3 seconds on / 2 seconds off.
[0111] Ultrasonic release module (concave side): frequency 1MHz, power 1.5W / cm², continuous mode output.
[0112] Treatment process: Phase 1 (0-20 minutes): Pretreatment with thermotherapy. The patient lies on their side on the mattress support platform, with the convex side facing down. The thermotherapy module is activated, maintaining the target temperature and low-frequency vibration throughout the treatment. Airbags, electrical stimulation, and ultrasound are not activated. This phase aims to increase local tissue temperature, promote blood circulation, and reduce fascial viscosity.
[0113] Phase 2 (20-30 minutes) Multimodal collaborative intervention: While the thermotherapy continues, the airbag module is activated, causing the convex side airbag to slowly inflate and rise to the preset height, forming a stretching surface.
[0114] The system simultaneously activates the low-frequency electrical stimulation module on the convex side and the ultrasonic release module on the concave side, maintaining stable parameter output. The central control system monitors temperature and pressure sensor feedback in real time, automatically fine-tuning the output power and airbag height when necessary.
[0115] End and Assessment: After the 30-minute treatment, the system sequentially shuts down each module and records parameters such as traction pressure, electrical stimulation intensity, ultrasound power, and skin temperature. The therapist inquires about the patient's subjective comfort and arranges postoperative assessment (ultrasound, MRI, and flexibility testing).
[0116] Results (observation after a single treatment): Palpation of the paraspinal muscles on the concave side showed decreased tension, while the contractile strength of the muscles on the convex side improved. The patient reported a reduction in back stiffness and no adverse reactions such as skin erythema, overheating, or pain.
[0117] Example 2: Preoperative flexibility training for patients with mild AIS: Patient Information: Gender / Age: Male, 14 years old; Diagnosis: Adolescent idiopathic scoliosis, Cobb angle 22° (thoracic segment); Objective: To improve spinal flexibility preoperatively in order to optimize the corrective effect during surgery.
[0118] Treatment settings: Traction angle 10°, target temperature for thermotherapy 38°C.
[0119] Electrical stimulation intensity 15mA, ultrasound power 1.0W / cm².
[0120] Five times a week for two consecutive weeks.
[0121] Results (2 weeks later): Imaging measurements showed a 4° decrease in the Cobb angle. MRI showed decreased T2 signal in the concave paraspinal muscles, indicating improved muscle tension. The patient's preoperative range of motion for forward flexion and lateral bending increased.
[0122] In the example above, the array-type electric airbag traction module allows for personalized adjustment: based on the patient's Cobb angle input data, the inflation and deflation of the airbags are controlled independently in zones to achieve directional traction on the convex side and personalized tilt angle settings, avoiding the non-targeted problems of existing symmetrical traction. Convex / Concave Side Differentiated Synchronous Treatment Layout: The convex side is equipped with a low-frequency electrical stimulation module for muscle activation, while the concave side is equipped with an ultrasonic release module for myofascial release. Both modules work simultaneously, achieving a synergistic effect of strength balance and flexibility improvement. Multimodal Collaborative Control System: The central control system can automatically operate according to the set treatment sequence (thermotherapy → traction + electrical stimulation + ultrasound) and parameters, and adjusts the output in real time based on temperature, pressure, and optional electromyography sensor feedback, achieving closed-loop safety control. Integrated Mattress Platform Design: All treatment modules are integrated into a single mattress platform, reducing patient positioning adjustments and equipment switching, improving rehabilitation efficiency and compliance.
[0123] Specifically, an array of electric airbags enables independent zoned adjustment based on the Cobb angle, creating directional traction force targeting the convex side and avoiding the non-targeted problems of existing symmetrical traction. Multimodal synergistic intervention integrates physical therapy methods such as thermotherapy, low-frequency electrical stimulation, and ultrasonic release, achieving simultaneous activation of muscles on the convex side and fascia release on the concave side, improving the biomechanical adaptability of soft tissues on both sides of the spine. A 20-minute pretreatment phase of the thermotherapy module is introduced, continuing to operate during subsequent traction, electrical stimulation, and ultrasonic treatments, thereby reducing tissue viscosity, promoting blood flow, and improving treatment comfort and effectiveness. A central control system coordinates the operating parameters of each module, allowing for safe adjustments based on real-time sensor feedback. Integrating multiple treatment methods onto a single mattress platform reduces patient positioning changes and equipment switching, lowers operational complexity, and improves patient compliance and rehabilitation experience in adolescents.
[0124] Through the above design, the present invention can simultaneously improve spinal flexibility, balance the distribution of paraspinal muscle strength, and enhance the effect of braces or preoperative correction in a single treatment, providing an efficient, safe, and personalized rehabilitation treatment approach for non-surgical intervention of AIS.
[0125] In one embodiment, this example provides a multifunctional device for scoliosis rehabilitation, which can, as Figure 2 As shown: Includes: a rehabilitation traction support platform 201, an array-type electric airbag traction module 202, a thermomagnetic therapy module 203, a low-frequency electrical stimulation module 204, an ultrasound module 205, and a central control system 206, wherein: The rehabilitation traction support platform 201 is used to support the target object. It is long and narrow, with its length direction corresponding to the head and tail direction of the target object and its width direction corresponding to the left and right direction of the target object. The array-type electric airbag traction module 202 is installed inside the rehabilitation traction support platform and is used to perform directional lifting and traction on the convex thoracolumbar segment of the target object to improve spinal flexibility and provide space for orthopedic correction. The thermomagnetic therapy module 203 is located inside the rehabilitation traction support platform, above the array-type electric airbag traction module, and adjacent to the array-type electric airbag traction module. It is used to activate before traction begins to pre-treat the paraspinal muscles and fascia tissue of the target object with a combination of thermo-magnetic and magnetic field. The low-frequency electrical stimulation module 204 is located inside the rehabilitation traction support platform in the area corresponding to the paraspinal muscles on the convex side of the target object, and is used to perform electrical stimulation on the paraspinal muscles on the convex side when the target object lies on its convex side with its convex side down. The ultrasound module 205 is installed on the side wall of the rehabilitation traction support platform corresponding to the concave side of the target object, and is used to perform ultrasonic loosening on the concave side of the target object's body surface; The central control system 206 is located in the control box inside the rehabilitation traction support platform and is electrically connected to the array-type electric airbag traction module, the thermomagnetic therapy module, the low-frequency electrical stimulation module, and the ultrasound module. The central control system is configured to: acquire imaging data of the target object; generate a three-dimensional traction support surface matching the lateral curvature of the target object and control commands for the array-type electric airbag traction module based on the imaging data; control the thermomagnetic therapy module to perform preprocessing; after preprocessing, activate the array-type electric airbag traction module and coordinately control the low-frequency electrical stimulation module and the ultrasound module to perform convex side traction and electrical stimulation, and concave side ultrasound release in a coordinated manner; during the traction process, adaptively adjust the three-dimensional traction support surface based on the pressure sensor feedback of the array-type electric airbag traction module.
[0126] Specifically, the aforementioned rehabilitation traction support platform 201 can be a multi-layered composite structure, which, from top to bottom, includes: a contact surface layer, a functional module support layer, a traction support layer, and a bottom support layer. The contact surface layer, made of flexible material, directly contacts the target object and provides support. The functional module support layer, located below the contact surface layer, is an integrally formed or modular support structure with multiple pre-set module installation areas, wiring channels, and fixing holes for installing array-type electric airbag traction modules, thermomagnetic therapy modules, low-frequency electrical stimulation modules, and sensors. The traction support layer, located below the functional module support layer, supports the array-type electric airbag traction modules and maintains the overall structural stability of the mattress during traction. The bottom support layer, located at the bottom of the mattress, is a semi-rigid or rigid structure that provides overall strength support and prevents excessive deformation of the mattress during lateral traction.
[0127] The aforementioned array-type electric airbag traction module 202 may include: multiple segmented strip-type airbag units arranged sequentially along the length of the mattress, with each airbag unit corresponding to a spinal segment. Each airbag unit is connected to an air pump and a solenoid valve assembly via an air passage. When the target object lies on its convex side downwards, the inflation height and pressure of different strip-type airbag units are differentially controlled to form an asymmetrical three-dimensional traction support surface on the contact surface, thereby directionally lifting and stretching the convex thoracolumbar segment to improve spinal flexibility and provide space for orthopedic correction. Pressure sensors are configured in the airbag units to achieve segmented independent inflation and deflation and pressure monitoring. During the traction process, the array-type electric airbag traction module receives control commands from the central control system. These control commands are calculated based on the target object's imaging data to obtain target traction surface parameters, which are then discretized into target height parameters and target pressure parameters corresponding to the segmented strip-type airbag units. The imaging data may include, but is not limited to, at least one of the following: the Cobb angle of the main curve, the position of the apex vertebra, the positions of the upper and lower vertebrae, and vertebral rotation indices.
[0128] The aforementioned thermomagnetic therapy module 203 may include: a distributed heating unit, a magnetic therapy unit, and a temperature sensor, wherein: the distributed heating unit is used to provide a heating effect to the target area of the target object; the magnetic therapy unit is a permanent magnet array or an electromagnet array, located adjacent to the distributed heating unit, and is used to form a stable and controllable magnetic field in the target area; the temperature sensor is used to collect temperature information of the contact surface and feed it back to the central control system.
[0129] The aforementioned low-frequency electrical stimulation module 204 may include: a flexible electrode unit disposed within the contact surface layer, the flexible electrode unit being arranged along the length direction to cover the paraspinal muscle region on the convex side from the thoracolumbar to the lumbar region; electrode leads and internal wiring channels; and a low-frequency electrical stimulation output unit electrically connected to the central control system; wherein the flexible electrode unit is embedded and fixedly connected to the main body to maintain stable contact with the target object's skin in a lateral position; during the rehabilitation process, it receives control signals from the central control system to limit or interrupt the electrical stimulation output based on the contact status or abnormal signals, and performs an interruption operation in response to the control signals.
[0130] The aforementioned ultrasound module 205 may include: a flexible waist belt, the first end of which is fixedly connected to the side wall of the rehabilitation traction support platform corresponding to the thoracolumbar region of the human body, and the second end of which is a free end; at least one ultrasound transducer unit is embedded in the inner side of the flexible waist belt, and the ultrasound transducer unit is attached to the skin of the target object through a coupling layer. When the target lies on its convex side on the platform, the free end of the flexible waist belt can wrap around the outer side of the target's thoracolumbar region and be detachably fixed to the other side wall of the platform, so that the ultrasonic transducer unit covers the concave paravertebral region of the target, thereby stably applying ultrasonic energy to the concave paravertebral muscles and fascia region.
[0131] In implementation, the ultrasound module 205 may further include a tension adjustment structure and a limiting structure, used to limit the pressure of the waist belt on the chest and waist of the target object in the wrapped state. The ultrasound module is electrically connected to the central control system in the main body through the internal wiring channel of the waist belt, and the central control system realizes unified start-stop and parameter control.
[0132] The aforementioned central control system 206 may include: a processing unit, a human-machine interaction unit, and a parameter storage unit, wherein: the human-machine interaction unit is used to input information about the target object and its operating mode; the processing unit is used to perform traction surface calculation, module collaborative control, and safety judgment; and the parameter storage unit is used to store preset execution schemes and execution process data.
[0133] To ensure the safety of the equipment, the aforementioned multifunctional rehabilitation equipment may further include: a safety monitoring system, which is signal-connected to the central control system for real-time monitoring of safety parameters during execution and transmitting the monitored safety parameters to the central control system in real time; the safety monitoring system may include: an airbag pressure monitoring unit for monitoring the inflation pressure of each segment airbag; a temperature monitoring unit for monitoring the temperature of the contact surface; an electrical stimulation and ultrasound output monitoring unit for monitoring whether the output status is abnormal; and a contact status monitoring unit for determining whether the electrodes or ultrasound transducers are in effective contact.
[0134] Based on the aforementioned multifunctional device for scoliosis rehabilitation, this example also provides a rehabilitation method, such as... Figure 3 As shown, it may include the following steps: Step 301: Obtain the imaging data of the target object.
[0135] Step 302: Based on the imaging data, generate a three-dimensional traction support surface that matches the side bending shape of the target object and control commands for the array-type electric airbag traction module.
[0136] Step 303: Control the thermomagnetic therapy module for pretreatment; after the pretreatment is completed, start the array-type electric airbag traction module, and coordinate with the low-frequency electrical stimulation module and the ultrasound module to make the convex side traction and electrical stimulation and the concave side ultrasound release work together.
[0137] Step 304: During the traction process, the three-dimensional traction support surface is adaptively adjusted based on the pressure sensor feedback from the array-type electric airbag traction module.
[0138] Specifically, acquiring imaging data of the target object and calculating target traction surface parameters based on the imaging data may include: determining the segmental range and convex direction of the traction action based on the imaging data, and calculating the target traction surface parameters corresponding to the side bending shape of the target object based on the determined segmental range and convex direction of the traction action. The target traction surface is discretized into target height or target pressure parameters corresponding to the segmented strip airbag units. Each airbag unit is inflated and deflated according to the corresponding parameters. During the traction process, the central control system performs closed-loop fine-tuning of the output of each segmented strip in combination with airbag pressure feedback, so that the actual formed traction support surface approaches a three-dimensional traction support surface that matches the side bending shape of the target object.
[0139] In other words, the central control system, combined with airbag pressure feedback, performs closed-loop fine-tuning of the output of each segment strip, ensuring that the actual traction support surface matches or closely approximates the three-dimensional traction support surface that matches the lateral curvature of the target patient. This achieves individualized and precise traction for coronal lateral curvature and accompanying rotational deformities in AIS patients. Specifically, in implementation, the central control system can calculate the target working state of each airbag unit in the array-type electric airbag traction module based on a vector synthesis algorithm of multi-source physiological parameters. This allows for simultaneous improvement of coronal lateral curvature and horizontal rotation in three-dimensional space, and personalized adaptation based on the soft tissue conditions of the target patient.
[0140] In one implementation, calculating the target traction surface parameters corresponding to the lateral bending morphology of the target object based on imaging data may include: S1: Based on the Cobb angle of the main curve and the position of the apex vertebra measured from the standing full spine X-ray of the target object, a corrective surface distribution function conforming to biomechanics is constructed. The corrective surface distribution function decreases in a Gaussian or parabolic distribution with the apex vertebra as the center. S2: Obtain the vertebral rotation angle sequence Ri from the MRI or CT images of the target object, where Ri represents the rotation angle of the vertebral body corresponding to the segment of the i-th airbag unit.
[0141] S3: Determine the preset height of the corresponding airbag unit based on the rotation angle Ri. The larger the rotation angle, the higher the preset height of the corresponding airbag unit. Utilize the torque generated by gravity and the reaction force of the airbag to push the ribs forward and drive the vertebral body to rotate. S4: Calculate the flexibility index of the target object according to the following formula: Flexibility index = (Standing Cobb angle - Bending Cobb angle) / Standing Cobb angle, and normalize it to a value between 0 and 1; Based on the Cobb angle of the main curve, the distribution function of the corrected surface, the vertebral rotation angle sequence, and the flexibility index, the target lift height of each airbag unit is calculated according to the following formula: Hi=K_safe×F_idx×[Wc×C×G(i)+Wr×Ri]; Where Hi represents the target lifting height of the i-th airbag unit, K_safe represents the system's preset safety threshold coefficient, F_idx is the flexibility index, Wc is the lateral curvature correction weight coefficient, representing the basic lifting height corresponding to each degree of Cobb angle, C represents the Cobb angle reading of the main curve, G(i) represents the correction surface distribution function based on the apex position, Wr represents the rotation correction weight coefficient, representing the additional compensation height corresponding to each degree of rotation angle, Wr×Ri represents the preset height, and the array airbag has a total of N airbag units, with index i, where i takes values from 1 to N.
[0142] By determining the target lifting height of each airbag in this way, the airbag array can form an asymmetric three-dimensional traction surface that conforms to the lateral bending shape (the Cobb angle determines the peak position), compensates for rotational distortion (the rotation angle determines local fine-tuning), and adapts to tissue elasticity (flexibility determines the overall amplitude).
[0143] Specifically, an array of electric airbags enables independent zoned adjustment based on the Cobb angle, creating directional traction force targeting the convex side. This avoids the non-targeted problems of existing symmetrical traction. By integrating physical therapy methods such as thermotherapy, low-frequency electrical stimulation, and ultrasonic release, simultaneous activation of muscles on the convex side and fascia release on the concave side are achieved, improving the biomechanical adaptability of soft tissues on both sides of the spine. Pre-treatment with a thermotherapy module allows for continuous operation during subsequent traction, electrical stimulation, and ultrasonic treatments, reducing tissue viscosity, promoting blood flow, and improving treatment comfort and effectiveness. A central control system coordinates the operating parameters of each module and allows for safe adjustments based on real-time sensor feedback. By integrating multiple treatment methods onto a single mattress platform, patient positioning changes and equipment switching are reduced, operational complexity is lowered, and patient compliance and rehabilitation experience are improved in adolescents.
