Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adaptive rehabilitation exercise device for hemiplegic limb spasticity after stroke and its working method. Background Technology

[0002] Stroke is a common neurological disease that often leads to hemiplegia, and limb spasticity is one of the common complications in hemiplegic patients. Limb spasticity seriously affects the recovery of limb function, reduces quality of life, and increases the difficulty of care and the burden on families. Prevention of spasticity mainly involves limb movement training, with standing being the optimal posture.

[0003] However, rehabilitation exercises mainly rely on manual therapy by rehabilitation therapists and patient-led rehabilitation training, but they have the following problems: 1. Lack of personalization: The degree of spasticity, limb function and rehabilitation needs vary among patients, making it difficult for traditional methods to be adjusted according to individual circumstances; 2. Difficulty in controlling training intensity: During training, patients may be unable to withstand the predetermined training intensity due to spasms, resulting in poor training effects or even secondary injuries. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive rehabilitation exercise device for hemiplegic limb spasticity after stroke and its working method, which features real-time adjustment of exercise intensity to avoid secondary injury.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive rehabilitation exercise device for hemiplegic limb spasticity in stroke patients, comprising support columns fixedly installed at the four corners of the top of a base, a fixed frame fixedly installed at the top of the support columns, a first sliding groove opened on the top of the base, a movable plate slidably installed on the inner side of the first sliding groove, a fixed rod fixedly installed on the inner side of the base, a motor fixedly installed at the bottom of the fixed rod, a first electric telescopic rod rotatably installed at both ends of the central axis of the fixed rod, and the motor being gear-driven with the central axis through a reducer, a pedal rotatably installed at one end of the first electric telescopic rod, a rotating wheel rotatably installed above the fixed frame, a traction rope rollingly sleeved on the outer side of the rotating wheel, pull rings fixedly installed at both ends of the traction rope, a fixed plate fixedly installed at the bottom of the fixed frame, an arc-shaped backing plate movably installed on one side of the fixed plate, a fixed strap fixedly connected to the front of the arc-shaped backing plate, and a first muscle tension sensor and a second muscle tension sensor fixedly connected to the bottom of the fixed frame.

[0006] As a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, the base is fixedly installed with support feet at the four bottom corners, and a support plate is fixedly installed at the front of the base, with the support plate and the support feet being fixedly connected and installed.

[0007] In a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, the first muscle tension sensor corresponds to the position of the patient's arm, the second muscle tension sensor corresponds to the position of the patient's leg, and a muscle tension sensor is fixedly installed on one side of both the first and second muscle tension sensors.

[0008] In a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, a second electric telescopic rod is fixedly installed at the bottom of the base, and the output end of the second electric telescopic rod is fixedly connected to the bottom end of the movable plate.

[0010] In a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, a support block is fixedly installed on the top of the fixed frame, and the support block is rotatably mounted with the rotating wheel.

[0011] In a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, a third electric telescopic rod is fixedly installed on one side of the fixed plate, and the output end of the third electric telescopic rod is fixedly installed with the arc-shaped backing plate.

[0012] In a preferred embodiment of the adaptive rehabilitation exercise device for hemiplegic limb spasticity in the present invention, a second sliding groove is provided on the inner side of the fixing plate, the arc-shaped backing plate is slidably installed with the second sliding groove, and a power-off button is fixedly installed on one side of the pull ring, and the power-off button is electrically connected to the third electric telescopic rod.

[0013] The working method of the adaptive rehabilitation exercise device for hemiplegic limb spasticity after stroke includes the following steps: Step 1: Secure the patient to one side of the curved backrest by fastening the arm below the patient's body with a strap. Step 2: When exercising the legs, place the patient's two feet on the corresponding pedals and secure them with the second strap. Then, attach the second muscle tension sensor to the patient's leg. Step 3: By starting the motor, the first electric telescopic rod and pedal can be moved to exercise the patient's legs.

Step 4: When exercising the patient's arm, have the patient hold the pull ring with both hands and tie the hands with the first strap, leaving the thumb on the normal side of the patient's arm exposed so that the power off button on the pull ring can be pressed and controlled. Then, tie the first muscle tension sensor to the patient's arm. Step 5: By using the normal arm to pull and loosen the ring, the patient's arm can be exercised. When the patient's muscles contract and generate tension, the first muscle tension sensor converts the pressure signal into an electrical signal, which is then amplified by the signal amplification circuit and transmitted to the intelligent control system. This system can accurately capture minute changes in muscle tension. By extending the fixed plate, the arc-shaped backing plate moves upward along the second slide, lifting the patient's body upward. Adjusting the stretching state of the patient's arm by using the normal arm to pull and loosen the ring reduces unnecessary damage. Step Six: After the exercise is completed, help the patient from the exercise device to the hospital bed to rest. The intelligent control system stores the patient's training data in the internal memory and transmits the data to the external rehabilitation management system or the rehabilitation therapist's terminal device through the communication module. The analysis facilitates the design of the next exercise plan.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Hemiplegic patients often experience muscle spasms due to their illness, which severely affects their quality of life.

[0019] Please see Figures 1 to 6 An adaptive rehabilitation exercise device for hemiplegic limb spasticity after stroke includes support columns 4 fixedly installed at the four corners of the top of a base 1. A fixed frame 5 is fixedly installed at the top of the support columns 4. A first sliding groove 6 is opened on the top of the base 1. A movable plate 12 is slidably installed on the inner side of the first sliding groove 6. A fixed rod 14 is fixedly installed on the inner side of the base 1. A motor is fixedly installed at the bottom of the fixed rod 14. A first electric telescopic rod 13 is rotatably installed at both ends of the central axis of the fixed rod 14. The motor is geared to the central axis through a reducer. A pedal 8 is rotatably installed at one end of the first electric telescopic rod 13. A rotating wheel 16 is rotatably installed above the fixed frame 5. A traction rope 17 is rolled around the outer side of the rotating wheel 16. Pull rings 7 are fixedly installed at both ends of the traction rope 17. A fixed plate 11 is fixedly installed at the bottom of the fixed frame 5. An arc-shaped backing plate 21 is movably installed on one side of the fixed plate 11. A fixing strap 23 is fixedly connected to the front of the arc-shaped backing plate 21. A first muscle tension sensor 9 and a second muscle tension sensor 10 are fixedly connected to the bottom of the fixed frame 5.

[0020] The patient's arm is secured to one side of the curved backrest 21 via a fixing strap 23. Starting the motor drives the first electric telescopic rod 13 and the pedal 8 to move, exercising the patient's leg. When the patient's muscles contract and generate tension, the second muscle tension sensor 10 converts the pressure signal into an electrical signal, which is amplified by the signal amplification circuit and then transmitted to the intelligent control system. This system accurately captures minute changes in muscle tension. Through this adaptive rehabilitation exercise device, significant improvement can be achieved. With continuous and gentle stretching and movement stimulation, it precisely targets spastic muscles, effectively promoting relaxation, gradually improving joint mobility, and significantly reducing pain and discomfort, thus relieving spasms.

[0021] Support feet 2 are fixedly installed at the four corners of the bottom of the base 1, and support plate 3 is fixedly installed at the front of the base 1. The support plate 3 is fixedly connected to the support feet 2. The first muscle tension sensor 9 corresponds to the position of the patient's arm, and the second muscle tension sensor 10 corresponds to the position of the patient's leg. Muscle tension sensors are fixedly installed on one side of both the first muscle tension sensor 9 and the second muscle tension sensor 10.

[0022] The muscle tension sensor uses a piezoelectric type. When the patient's muscles contract and generate tension, the sensor converts the pressure signal into an electrical signal, which is then amplified by the signal amplification circuit and transmitted to the intelligent control system. The muscle tension sensor has the characteristics of high sensitivity and fast response, and can accurately capture minute changes in muscle tension.

[0023] A second electric telescopic rod 15 is fixedly installed at the bottom of the base 1, and the output end of the second electric telescopic rod 15 is fixedly connected to the bottom end of the movable plate 12.

[0024] The second electric telescopic rod 15 drives the movable plate 12 to move along the first slide rail 6, which can move the movable plate 12 to a position above the pedal 8 and the first electric telescopic rod 13, making it easier for the patient to stand on the top of the base 1. The extension and retraction of the third electric telescopic rod 22 can drive the arc-shaped backrest 21 to move up and down along the second slide rail 20, thereby enabling the patient who is tied to one side of the arc-shaped backrest 21 to perform squatting exercises.

[0025] The outer side of the pull ring 7 is fixedly connected to a first strap 24, and the outer side of the pedal 8 is fixedly connected to a second strap 25; a support block 19 is fixedly installed on the top of the fixing frame 5, and the support block 19 is rotatably installed with the rotating wheel 16.

[0026] The first strap 24 can be used to tie the patient's hand to the pull ring 7 for gripping and fixation, and the second strap 25 can be used to tie the patient's foot to the pedal 8 for fixation. The support block 19 provides rotational support for the rotating wheel 16, allowing the rotating wheel 16 to assist in the loosening of the traction rope 17, thus better exercising the arm.

[0027] A third electric telescopic rod 22 is fixedly installed on one side of the fixed plate 11, and the output end of the third electric telescopic rod 22 is fixedly installed with the arc-shaped backing plate 21; a second sliding groove 20 is opened on the inner side of the fixed plate 11, and the arc-shaped backing plate 21 is slidably installed with the second sliding groove 20; a power off button 18 is fixedly installed on one side of the pull ring 7, and the power off button 18 is electrically connected to the third electric telescopic rod 22.

[0028] During the rehabilitation exercises for the arm, the patient's arm can be effectively exercised by using the normal arm to pull and loosen the pull ring 7. When the patient's muscles contract and generate tension, the first muscle tension sensor 9 quickly converts the pressure signal into an electrical signal, which is then amplified by the signal amplification circuit and transmitted to the intelligent control system. This system can accurately capture subtle changes in muscle tension. Then, the fixed plate 11 extends, causing the arc-shaped backing plate 21 to move upward along the second slide groove 20 structure, thereby moving the patient's body upward. Moreover, by using the normal arm to pull and loosen the pull ring 7, the stretching state of the patient's arm can be flexibly changed, effectively reducing the risk of unnecessary injury. If any discomfort is felt during the exercise, the device can be powered off and the exercise stopped by pressing the power off button 18 with the thumb. Power off will trigger an alarm device to remind medical staff to carry out emergency assistance and rescue operations.

[0029] Among them, such as Figure 6 As shown, the intelligent control system uses a microprocessor based on the ARM architecture as the core control unit. This microprocessor has the characteristics of high performance and low power consumption, which can meet the device's requirements for real-time data processing and control. The intelligent control system mainly includes a data acquisition module, a data analysis module, a control decision module, and a communication module. Data acquisition module: responsible for receiving various physiological signals collected by the sensor module, performing analog-to-digital conversion and preprocessing, and then transmitting them to the data analysis module; Data analysis module: It uses advanced algorithms to analyze and process the collected data, such as using fuzzy control algorithms to assess the degree of spasticity and using neural network algorithms to predict the patient's recovery trend. The analysis results will be transmitted to the control decision module. Control Decision Module: Based on the results of the data analysis module and the preset training scheme, it generates corresponding control commands to control the working parameters of the drive module and realize the adaptive adjustment of training parameters; Communication module: Supports wired and wireless communication methods, such as USB interface and Bluetooth module, for data transmission and communication with external devices, facilitating remote monitoring and adjustment of training programs by rehabilitation therapists.

[0030] The working method of the adaptive rehabilitation exercise device for hemiplegic limb spasticity after stroke includes the following steps: Step 1: Secure the patient to one side of the curved backrest 21 by fastening the lower arm area of ​​the body with the fixation strap 23; Step 2: When exercising the legs, place the patient's two feet on the corresponding pedals 8 and secure them with the second strap 25. Then, attach the second muscle tension sensor 10 to the patient's leg. Step 3: By starting the motor, the first electric telescopic rod 13 and the pedal 8 can be moved to exercise the patient's legs. When the patient's muscles contract and generate tension, the second muscle tension sensor 10 will convert the pressure signal into an electrical signal, which will be amplified by the signal amplification circuit and then transmitted to the intelligent control system, which can accurately capture the minute changes in muscle tension. Step 4: When exercising the patient's arm, hold the pull ring 7 with both hands and tie the hands with the first strap 24, leaving the thumb on the normal arm side exposed so that the power off button 18 on the side of the pull ring 7 can be pressed and controlled. Then, tie the first muscle tension sensor 9 to the patient's arm. Step 5: By using the normal arm to pull and loosen the pull ring 7, the patient's arm can be exercised. When the patient's muscles contract and generate tension, the first muscle tension sensor 9 will convert the pressure signal into an electrical signal, which will be amplified by the signal amplification circuit and then transmitted to the intelligent control system. This system can accurately capture minute changes in muscle tension. By extending the fixed plate 11, the arc-shaped backing plate 21 will move upward along the second slide groove 20, thus lifting the patient's body upward. By using the normal arm to pull and loosen the pull ring 7, the stretching state of the patient's arm can be adjusted, reducing unnecessary damage. Step Six: After the exercise is completed, help the patient from the exercise device to the hospital bed to rest. The intelligent control system stores the patient's training data in the internal memory and transmits the data to the external rehabilitation management system or the rehabilitation therapist's terminal device through the communication module. The analysis facilitates the design of the next exercise plan.

[0031] In summary, this adaptive exercise device can accurately monitor key physiological indicators such as the degree of limb spasticity and muscle strength in patients in real time. Based on this dynamic data, it can automatically and flexibly adjust the resistance and speed of training, and tailor a personalized rehabilitation training program to help patients effectively relieve limb spasticity and accelerate the recovery of limb function.
