Abstract

The invention relates to a neck health monitoring system which comprises a muscle strength detection module for detecting neck muscle groups and a processor for providing neck muscle group health guidance for a subject based on feedback of the muscle strength detection module. The muscle force detection module obtains the maximum stress when the neck extensor group of the subject contracts at equal length, and the processor generates corresponding health guidance suggestions based on the functional grade corresponding to the data which is fed back by the muscle force detection module and represents the maximum stress of the subject. Through long-time observation, the inventor finds that based on the physique of the subject (especially the subject with chronic disease or prognosis risk), the detection standard needs to be dynamically changed, and the dynamic detection standard is beneficial to improving the accuracy of the detection result.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a neck health monitoring system. Background Art

[0002] The posterior cervical muscles play a leading role in supporting the cervical spine. Due to the physiological forward curvature of the cervical spine and bad habits in work and life, the front of the cervical spine is often subjected to compressive stress, and the back is often subjected to tensile stress. Continuous excessive stretching can cause chronic strain of the posterior muscles, which can cause the functional decline of the posterior cervical support mechanism, cervical instability, aggravate the degeneration of the intervertebral disc and bone joints, and thus lead to the occurrence and development of various types of cervical spondylosis. For example: Ye Tianwen et al. published a review in the "Chinese Journal of Bone and Joint Injury" to clarify the relationship between lesions of the cervical muscle system and cervical spondylosis, which detailed the impact of lesions of the cervical muscle tissue on the onset and progression of cervical spondylosis.

[0003] Neck muscle weakness and neck muscle strain are common clinical pathologies. Zhong Yuanming et al. published a research report on the prevention of cervical spondylotic myelopathy by four-way resistance static functional exercise of neck muscles at the 17th National Academic Symposium on Integrative Traditional Chinese and Western Medicine Traumatology in 2009. There are also many devices for assisting subjects or people whose necks are in an incorrect posture for a long time. For example, a Chinese patent with publication number CN111700619A discloses a neck rehabilitation auxiliary system. The system obtains image information of the horizontal turning process of the neck of the object during neck rehabilitation training by taking photos or recording videos with a forward-fixed camera, and obtains the position of the nose tip and chin tip of the object in the image information and marks them. The system recognizes the rotation angle of the neck by the image of the head rotation process, which is used to standardize the rotation force and angle in neck rehabilitation training. There are many devices for correcting exercise posture or assisting exercise in the prior art, and most of them are universal.

[0004] Limited by the resource distribution of professionals and the difficulty of seeking medical treatment, people often use pain as a criterion for judging whether the neck muscles have recovered, whether it is rehabilitation training for prognosis recovery or rehabilitation training for muscle damage. Although pain can provide direct feedback about injury or pressure, relying solely on pain to judge neck recovery has limitations in the assessment of neck recovery. For example, as the patient's pain continues to occur, the patient will gradually enter a state of dull pain, and there is a high possibility that the assessment of the prognosis of the neck muscles will be biased and the rehabilitation training will be stopped or increased. In particular, for patients with cervical spondylosis, patients with neck surgery (such as cervical fusion or carotid artery surgery), patients with muscle weakness caused by long-term bed rest or lack of activity, patients with diseases such as amyotrophic lateral sclerosis, or patients who have experienced neck trauma (such as car accidents, falls, etc.), due to the presence of many important main blood vessels and nerves in the neck, improper neck training can lead to serious consequences, including blood flow obstruction, nerve compression or injury, and other problems, which in turn cause headaches, dizziness, neuralgia or other neurological symptoms.

[0005] Therefore, it is particularly important to provide accurate rehabilitation training that combines the patient's physical sensations and objective detection parameters and changes dynamically with the patient's physical changes.

[0006] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0007] In order to solve the above technical problems, the present application relates to a neck health monitoring system, which includes a muscle strength detection module for detecting neck muscles and a processor for providing neck muscle health guidance to subjects based on feedback from the muscle strength detection module.

[0008] The present application also relates to a neck health assessment system that resolves the mismatch between functionality and pain.

[0009] The muscle strength detection module obtains the maximum force of the subject's neck extensor muscles when they are in isometric contraction, and the processor generates corresponding health guidance suggestions based on the functional classification corresponding to the data characterizing the subject's maximum force fed back by the muscle strength detection module. Preferably, the processor can infer the subject's potentially damaged muscle groups through the subject's occupation and the subject's posture information collected online, and generate corresponding assessments in combination with mechanical data. The health guidance suggestions include rehabilitation training intensity evaluation indicators for guiding the subject's neck rehabilitation training. Specifically, the processor is configured to:

[0010] The adjustment cycle of the neck physical therapy program is based on the maximum force parameters and the maximum force parameter holding time collected by the muscle strength detection module, and the neck bending angle and shoulder-neck symmetry collected by the posture detection module, wherein the processor adjusts the parameters of the neck physical therapy program based on the changes in the cervical sagittal plane mobility, cervical kinesiology orientation, and cervical axial stability confirmed by the maximum force parameters and the maximum force parameter holding time collected by the muscle strength detection module, and the neck rotation parameters and bending parameters collected by the posture detection module, wherein the parameters of the neck physical therapy program include the maximum range of motion of the neck and the static resistance of the neck.

[0011] Beneficial effects of this technical solution:

[0012] This technical solution is based on clinical research that proves the strong correlation between the subject's neck muscle endurance and muscle status (or pain), and combines the changes in the mechanical properties of the neck muscle group to provide real-time feedback on the subject's muscle strength damage or muscle strength recovery, so that the relevant equipment for training the subject's neck muscle endurance can generate corresponding neck physical therapy programs in the dimension of the neck muscle group. At the same time, by converting the data of muscle strength detection into functional grading, the system can accurately evaluate the subject's neck muscle group status. This grading can help subjects understand their health status and provide doctors with valuable diagnostic information.

[0013] On the one hand, detecting the subject's maximum force as an indicator can confirm the subject's neck condition; on the other hand, detecting the subject's maximum force can also provide a reference standard for health guidance suggestions, that is, the processor can provide corresponding exercise suggestions based on the subject's muscle strength threshold.

[0014] According to a preferred embodiment, the data on the subject's maximum force strength includes the time length involved when the force of the subject's neck extensor muscles in isometric contraction first reaches and exceeds the first preset force and the last time it drops and falls below the first preset force.

[0015] Beneficial effects of this technical solution:

[0016] Different from the prior art that uses muscle strength as a detection indicator, this application uses the muscle tension holding time within a set muscle strength range. Using the above indicator has two advantages:

[0017] The detection method of muscle strength index may induce the subject to test in an unsafe way, that is, the subject may injure his cervical spine for the sake of explosive force in an instant. The detection method adopted by the present application uses muscle tension as the detection index, which requires the subject to maintain muscle tension for a period of time, and does not require the subject to maintain the highest contraction force at all times. Therefore, the risk of detection is greatly reduced;

[0018] At the same time, the inventors found through long-term observation that: based on the physique of the subjects (especially those with chronic diseases or prognostic risks), the detection standards need to change dynamically, and dynamic detection standards help to improve the accuracy of the test results. Specifically, for young and disease-free subjects, the cause of their neck damage is caused by non-standard normalized posture. Therefore, during the test, the first time the force reaches and exceeds 90% of the maximum force and the last time it drops and is lower than 90% of the maximum force is used as the effective start time and end time of the subject's action, and the start and end time intervals are recorded as functional indicators for evaluating the subject's cervical extensor group. For elderly subjects or subjects with cervical problems, during the test, the first time the force reaches and exceeds 80% of the maximum force and the last time it drops and is lower than 80% of the maximum force is used as the effective start time and end time of the subject's action, and the start and end time intervals are recorded as functional indicators for evaluating the subject's cervical extensor group.

[0019] According to a preferred embodiment, when the data representing the maximum force exerted by the subject is within a first range, the processor generates a first general physical therapy pattern including neck flexion, extension and rotation.

[0020] According to a preferred embodiment, when the data characterizing the maximum force applied to the subject is within the second range, the processor generates a first general physical therapy mode including neck flexion, extension and rotation and a cervical vertebrae function optimization treatment mode interleaved with the first general physical therapy mode, wherein the processor can generate a cervical vertebrae function optimization treatment mode for exercising the muscle groups that suffer the most severe muscle strength damage due to the normalized posture in combination with the normalized posture of the subject fed back by the subject's posture detection module or the normalized posture of the subject corresponding to the subject's occupational information.

[0021] According to a preferred embodiment, when the data characterizing the maximum force applied to the subject is within a third range, the processor generates a first general physical therapy mode including neck flexion, extension and rotation, a second general exercise mode including neck resistance exercise, and a cervical vertebrae function optimization treatment mode which is respectively performed crosswise with the first general physical therapy mode and the second general exercise mode, wherein the processor can generate a cervical vertebrae function optimization treatment mode for exercising muscle groups which suffer the most severe muscle strength damage due to the normalized posture in combination with the normalized posture of the subject fed back by the posture detection module of the subject or the normalized posture of the subject corresponding to the subject's occupational information.

[0022] According to a preferred embodiment, the processor is capable of detecting the posture of the subject in an exercise state based on the generated health coaching suggestions for subsequent neck health assessment of the subject.

[0023] Beneficial effects of this technical solution:

[0024] The detection equipment and exercise equipment are combined to detect whether the subjects' movements during exercise are standard to confirm whether the movements can effectively reduce neck muscle damage.

[0025] The existing equipment relies on the self-discipline of the subjects during the exercise process, and the follow-up is based on the subjects completing the standard exercise program. On the one hand, unsupervised exercise will make the subjects lazy and gradually give up exercise or the exercise movements will become more and more out of shape; on the other hand, for subjects who have regular follow-up visits for a long time, spending a lot of time and energy on rehabilitation or exercise without the expected recovery effect will greatly undermine their confidence in continuing to exercise. For medical staff, if the subjects come for follow-up visits with non-standard postures or have not completed the rehabilitation course, the accuracy of their medical advice will be reduced or the obstacles to judging the development of the disease will increase. For example, after the subjects exercise or rehabilitate with non-standard postures, their neck muscle state will further decline. When such problems occur multiple times, medical staff may introduce other reference factors (such as illness) to increase the test items of the subjects (to exclude the above reference factors), which wastes the energy of the subjects on the one hand and increases the distrust between doctors and patients on the other hand.

[0026] According to a preferred embodiment, the muscle strength detection module includes a neck muscle force measuring unit for detecting the neck muscle strength of the subject; a human-computer interaction element for acquiring force parameters of the subject during the detection process provided by the neck muscle force measuring unit and generating data representing the maximum force of the subject, wherein the neck muscle force measuring unit is provided with a first force-bearing part that contacts the subject's head and neck, a second force-bearing part that contacts the subject's back, and a sensing part for detecting the force generated by the first force-bearing part.

[0027] According to a preferred embodiment, the human-machine interaction element is configured to obtain mechanical data collected by the sensing component when the subject's head and neck are tilted back to counteract the movement of the second force-bearing component to restrict the subject's back when the subject is in a sitting position.

[0028] According to a preferred embodiment, the first force-bearing part includes a wrapping piece that contacts the subject's headrest and partially wraps the subject's head, and the wrapping piece can rotate synchronously with the subject's head relative to the second force-bearing part. The processor can generate mechanical data during the process of the subject's head turning left or right to the maximum angle. Preferably, the mechanical data includes the length of time obtained by taking the head turning left to a preset threshold as the initial time point and the head turning from left to right to the preset threshold as the end time point. Preferably, the preset threshold is equal to the maximum rotation angle *a of the subject this time. a is not greater than 1.

[0029] Beneficial effects of this technical solution:

[0030] The neck exercises in the prior art follow the principle of universality and ignore the characteristics of different muscle group functions, and provide a unified exercise method for exercisers. On the one hand, this will increase the health care burden of exercisers; on the other hand, it will also make exercisers lack targeted rehabilitation training for muscle groups with problems. For example: a neck muscle strength exercise device disclosed in a Chinese patent with publication number CN112004582A. The device includes: a main body; a seat board portion, which is arranged at the front end of the above-mentioned main body, supporting the user's buttocks for the user to sit; a backrest portion, which is arranged at the rear end of the main body to support the user's back when the user sits on the above-mentioned seat board portion; a pushing movement portion, which is arranged on the above-mentioned backrest portion, and imparts resistance by pushing the head of the user sitting on the above-mentioned seat board portion backwards, so as to strengthen the user's neck muscles. Although the device is equipped with various force and angle detection sensors, they are only used for data collection and recording. In subsequent exercises, due to the confusion of the functions of the neck muscles, the generated exercise mode is still a universal exercise method that is only applicable to fitness enthusiasts (for example: the text states "In the first exercise mode, the drive of the load adjustment motor is controlled. At this time, if the user performs a neck movement of pushing the head contact part, the range of motion is gradually increased by pushing the head contact part from the initial position to the rear, thereby gradually increasing the resistance applied to the user's neck. That is, compared with the resistance applied to the neck when the head contact part is pushed about 50mm from the initial position, when the head contact part is further pushed from the initial position to about 80mm, the coil spring is further stretched, the elastic force becomes stronger, and the resistance applied to the neck becomes stronger. On the contrary, in the second exercise mode, through the control of the control unit, a constant resistance is provided to the neck of the user who pushes the head contact part, so that the user performs neck exercises with a constant exercise intensity"). Exercise is enhanced by increasing exercise resistance.

[0031] Unlike the prior art, the present application is also applicable to subjects with damaged neck muscles, such as office workers who sit for long periods of time. Since the damage to the neck muscles of subjects in different working environments is different, personalized customization of the exercise mode that suits their neck condition can effectively improve the health care effect of the neck muscles.

[0032] Specifically, the damage to each muscle group of the subject is analyzed based on the mechanical data generated when the head is tilted back and the head is rotated. In particular, the processor can confirm the damage to the muscle group based on the subject's occupation and in combination with the mechanical data, thereby generating a universal first exercise mode and a targeted second exercise mode, thereby achieving the purpose of efficient exercise. Specifically, the first exercise mode includes a first general physical therapy mode and a second general exercise mode. The second exercise mode includes a cervical spine function optimization treatment mode.

[0033] According to a preferred embodiment, the first force-bearing part contacts the headrest of the subject.

[0034] Beneficial effects of this technical solution:

[0035] The force exerted and received by the neck mainly depends on the small occipital muscles, sternocleidomastoid muscles and trapezius muscles connected to the headrest at one end, such as Figure 6 As shown, the load-bearing capacity when the head is tilted back can intuitively demonstrate the above-mentioned muscle status and coordination status.

[0036] On the one hand, this technical solution takes into account the distribution of the neck muscles tested by the subject and the optimal method of demonstrating muscle force; on the other hand, it also takes into account the safety of the subject's neck. The subject's neck bone structure is flexible, which means that when the subject applies force antagonism equipment, this part is prone to dislocation, bone wear and other problems. However, since the headrest is protected by the skull, the subject can use this position as a support point to control the neck muscle force without the above problems.

[0037] Another aspect of the present application relates to a neck health monitoring method. The neck health monitoring method comprises the following steps:

[0038] The maximum force of the subject's neck extensor muscles was obtained when they were in isometric contraction;

[0039] Corresponding health guidance recommendations are generated based on the functional classification corresponding to the data representing the maximum force to which the subjects can withstand. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The following is a detailed description with reference to the accompanying drawings.

[0051] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. "Several" means two or more, unless otherwise clearly and specifically limited. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In medical devices, the proximal end refers to the end of the device that is close to the operator when the device is operated, and the distal end refers to the end of the device that is away from the operator or performs corresponding operations on the subject when the device is operated.

[0052] Hypoalgesia refers to a weakened response to painful stimuli. There are many reasons for the occurrence of hypoalgesia, including changes in the nervous system, the effects of drugs or psychological factors.

[0053] Functional classification: The inventors found that differences in cervical function will lead to different clinical manifestations of the subjects' necks, and their risks for possible cervical diseases are also different. Based on long-term clinical experience, the inventors classified the cervical functions of subjects with different manifestations. Subjects in the first level of functionalism have good cervical muscle function, no chronic neck pain, neck stiffness and other manifestations, and the risk of related cervical diseases caused by cervical degeneration is low. It is only necessary to pay attention to maintaining healthy living habits, and no additional intervention is required. Subjects in the second level of functionalism have poor cervical muscle function, with chronic neck pain, neck stiffness and other manifestations, but no cervical-related diseases. It is recommended to perform correct and appropriate neck extensor muscle group exercises for primary prevention of cervical-related diseases. Subjects in the third level of functionalism have extremely poor cervical muscle function, loss of normal cervical sequence, accompanied by symptoms or severe symptoms of cervical spondylosis, and the possible prognosis of surgical treatment of cervical spondylosis is poor. Cervical rehabilitation exercises or pre-operative rehabilitation exercise guidance for cervical surgery are strongly recommended. Furthermore, through the study of follow-up visits or reexaminations at different levels of functional medicine, the inventors found that the neck conditions of the subjects who followed the doctor's advice and exercised regularly in the home environment were greatly improved.

[0054] Extensor muscles: The cervical extensor muscles include the upper trapezius, splenius capitis, splenius cervix, and bilateral sternocleidomastoid muscles. The cervical extensor muscles are the main muscle groups that affect the subject's posture, and the subject's posture will directly affect the subject's spine and other key parts (such as spinal misalignment or lumbar protrusion).

[0055] Isometric contraction: A contraction in which the length of a muscle remains constant while the tension changes. Isometric contraction of the neck extensors means that the length of the neck extensors remains constant while tension is generated to resist the external force. This type of contraction usually occurs when the muscles are working against a static load, such as when holding the head steady or maintaining a correct posture. Although the muscle is contracting, there is no significant change in length, so the joint angle does not change significantly. Isometric contractions help increase muscle stability and endurance.

[0056] The first preset strength is set by medical staff or other professionals based on the subject's condition. For example, when the subject is a healthy normal person, the first preset strength can be the maximum strength. When the subject is a subject with cervical dislocation, the first preset strength can be 70% of the maximum strength due to the limited use of neck strength.

[0057] The normalized posture includes the posture that the subject will maintain for a long time in daily work, study or life. For example, the normalized posture of IT personnel who face the computer for a long time during work hours is a hunched sitting posture. Or based on the detection data of the subject by the device such as the bracelet, the processor 200 sets the posture that the subject maintains the longest time when awake as the normalized posture.

[0058] The neck health assessment contains the subject's neck detection information and the exercise program corresponding to his / her neck condition.

[0059] Functional grading: The subject's neck functional status is divided into different levels according to the subject's performance in a specific functional activity or based on the evaluation results generated by the processor 200. These levels are generally used to evaluate the subject's neck functional status, reflect the subject's performance in a specific functional activity, or provide a basis for adjusting the subject's neck rehabilitation training.

[0060] The visual analogue scale (VAS) is used to assess pain. It is widely used in clinical practice in China. The basic method is to use a 10-cm long floating ruler with 10 scale marks on one side, with 0 and 10 marks at the two ends. 0 means no pain, and 10 means the most severe pain that is unbearable.

[0061] The Neck Disability Index (NDI) is designed to allow subjects with neck pain to conduct self-assessment. NDI has a total of 10 items, including: neck pain and related symptoms (pain intensity, headache, concentration and sleep) and daily living activities (personal care, lifting heavy objects, reading, work, driving and entertainment). The minimum score for each item is 0 points and the maximum score is 5 points. The higher the score, the more severe the degree of functional impairment. Cervical Function Impairment Index % = (sum of the scores of each item / number of items completed by the subject × 5) × 100%.

[0062] Cervical sagittal plane mobility refers to the ability of the cervical spine to move in the sagittal plane (i.e., front-to-back direction), including the range and flexibility of flexion (lowering the head), extension (raising the head), and forward and backward tilting. This mobility is essential for the normal function of the neck and affects the posture and movement of the head.

[0063] The cervical spine kinesiology orientation refers to the angular range and flexibility of the cervical spine in rotational movement. This assessment direction focuses on the movement ability of the cervical spine in the cervical kinesiology orientation, including the relative movement between the various cervical spine segments.

[0064] Axial stability of the cervical spine refers to the ability of the cervical spine to maintain its normal position and function under the action of axial load (i.e., force in the up and down directions), and represents the stability of the cervical spine when it is in a neutral position.

[0065] Shoulder and neck symmetry indicates the degree of symmetry between the two sides of the subject's shoulder and neck area. The goodness of symmetry can reflect the subject's possible muscle imbalance or dysfunction. Shoulder and neck symmetry can be replaced by the shoulder and neck symmetry index value. Shoulder and neck symmetry is the difference in shoulder height or neck angle.

[0066] Example 1

[0067] This embodiment provides a muscle strength detection module 100. This embodiment provides a muscle strength detection method.

[0068] The existing measurement methods for cervical mechanics and functionality in the field of cervical mechanics and functionality include: a. using an ordinary dynamometer to measure the maximum force of the cervical muscles; b. using the principle of isokinetic muscle contraction to measure the muscle torque and its changes during cervical movement, and evaluating the force and activity of the cervical spine through the above measurement results.

[0069] Different from the detection methods involved in the prior art, the present application detects the isometric muscle strength of the neck. Isometric muscle strength plays an important role in "sitting in meditation" in daily life. On the one hand, the use of isometric muscle strength to detect the state of the subject's neck can simplify the detection process, and since there is no need to control the test speed, test duration and test posture of the subject, the detection accuracy of the subject in a daily environment is greatly improved; on the other hand, since the neck involves key tissues such as the spinal cord, the use of isometric contraction and other measurement methods without the supervision of medical staff will increase the danger of the detection process (the danger caused by rapid displacement of the neck).

[0070] The muscle strength detection module 100 includes a neck muscle force measuring unit 120, which is used to detect the neck muscle strength of the subject; a human-computer interaction element 110, which obtains the force parameters of the subject during the detection process provided by the neck muscle force measuring unit 120 and generates data representing the maximum force of the subject, wherein the neck muscle force measuring unit 120 is provided with a first force-bearing part 130 that contacts the subject's head and neck, a second force-bearing part 140 that contacts the subject's back, and a sensor part 150 that detects the force generated by the first force-bearing part 130.

[0071] Specifically, Figure 1 As shown, the human-machine interaction element 110 is disposed in a box 160. A first force-bearing part 130 and a second force-bearing part 140 are respectively disposed on the same surface of the box 160.

[0072] Based on the structure of the human body, such as Figure 2 As shown, the first force-bearing part 130 is disposed at the upper half of the box body 160. The second force-bearing part 140 is disposed at the lower half of the box body 160. Figure 3 As shown, when a human body is in a sitting position close to the surfaces where the first force-bearing part 130 and the second force-bearing part 140 are arranged, the first force-bearing part 130 arranged in the upper half of the box body 160 fits the headrest of the human body, and the second force-bearing part 140 arranged in the lower half of the box body 160 fits the waist or back of the human body.

[0073] The first force-bearing part 130 is a semi-arc structure, which is used to match the shape of the subject's headrest. The second force-bearing part 140 is a slightly arc structure that can support the subject's back to be straight. Since the first force-bearing part 130 needs to bear force and the second force-bearing part 140 needs to resist the force generated by the subject's back being bent, the first force-bearing part 130 and the second force-bearing part 140 are made of hard materials.

[0074] Specifically, Figure 3 As shown, when the subject is being measured, the spine, especially the cervical spine, needs to maintain a relatively neutral position. The subject is commanded to extend the neck backwards toward the first force-bearing part 130 of the muscle strength detection module 100, and at the same time, the muscle strength detection module 100 applies the same amount of force to the subject's headrest from the first force-bearing part 130 to antagonize the action, and the second force-bearing part 140 continues to fix the subject's spine. The sensor part 150 of the muscle strength detection module 100 receives the corresponding information and transmits it to the human-machine interaction element 110. The human-machine interaction element 110 obtains the strength of the subject when performing the action. When the subject performs the action, the neck extensor muscles are isometrically contracted.

[0075] Preferably, the human-computer interaction element 110 describes the measurement process by recording a force-time curve with the force as the vertical coordinate and the measurement time as the horizontal coordinate, and uses the first time the force reaches and exceeds 80% of the maximum force and the last time it drops below 80% of the maximum force as the effective start time and end time of the subject's action, and records the start and end time interval as a functional indicator for evaluating the subject's cervical extensor muscle group.

[0076] Example 2

[0077] The hardware configuration of this embodiment is consistent with that of the previous embodiment, and only some optimizations are made in the hardware.

[0078] The device involved in this application can also be combined with a remote hospital database and related detection equipment worn by the subjects.

[0079] The remote hospital database includes the terminals of medical staff. The relevant testing equipment carried or worn by the subjects includes the subjects' mobile phones or wristbands and other devices.

[0080] Preferably, the processor 200 can send the test results and exercise status of the subject to the terminal of the medical staff under authorization. The medical staff can modify the test criteria of the subject in real time in the background, or adjust the generated exercise plan in combination with the subject's past medical history.

[0081] Preferably, the processor 200 can, with authorization, obtain the subject's daily posture information or the posture during self-exercise without the aid of equipment from relevant equipment carried or worn by the subject.

[0082] Based on the daily posture information of the subject, the processor 200 can correct the current normalized posture of the subject. For example, in combination with the subject's occupation information, the processor 200 generates the normalized posture of the subject as a long-term shrug sitting posture, but after a week of continuous daily posture information collection, since the subject frequently alternates between standing and sitting positions at work, his normalized posture may become a side-lying posture at night (i.e., this posture is used for a longer time), thereby improving the accuracy of muscle damage judgment.

[0083] At the same time, when the subject exercises his neck by himself, the processor 200 can also judge the subject's exercise posture through changes in hand posture (bracelet trajectory data collection) or the subject's exercise image (mobile phone image information collection).

[0084] For example: Without the aid of instruments, Figure 4 As shown, the training method for the trapezius muscle of the neck is that the subject bends the left arm and places it behind the back, and the palm of the right arm fits the left side of the head and presses down the head so that the neck drives the head to bend to the right. The bracelet worn on the right hand can judge whether the subject presses down the head based on the movement trajectory of the right hand (upward, low frequency and small decline).

[0085] When not using an instrument, the method of using neck resistance exercise is that the subject crosses his hands behind the head, stretches the head and neck backward with the maximum force, and resists forward with both hands with the same force. The two forces counteract each other to keep the cervical spine in a neutral position. Each set should be maintained for 10 seconds. When performing this exercise, the bracelet records the trajectory of the subject's hands, and if the hand does not stay in the set position for a continuous period of time, it is judged as unqualified and the subject is reminded to start again.

[0086] Example 3

[0087] The hardware configuration of this embodiment is consistent with that of the above-mentioned embodiment, and only improvements are made in data collection and processing.

[0088] The muscle strength detection module 100 obtains the maximum force of the subject's neck extensor muscles when they are in isometric contraction, and the processor 200 generates corresponding health guidance suggestions based on the functional grade corresponding to the data representing the maximum force of the subject fed back by the muscle strength detection module 100.

[0089] The system also includes a posture detection module for acquiring posture data of a human body in a detection state. The posture detection module can be a device mounted on the muscle strength detection module 100 or independently set at the shoulder and neck of the subject. The posture detection module is, for example, a posture sensor.

[0090] like Figure 6 and 7As shown, the processor obtains the functional classification based on the detection data transmitted by the muscle strength detection module 100 in combination with formulas (1) and (3). The processor obtains the posture score based on the detection data transmitted by the posture detection module in combination with formula (2). The evaluation result of the training intensity is obtained through formula (4), thereby providing a basis for adjusting the rehabilitation training of the subject. The evaluation result of the training intensity can be sent by the processor to the device used by the subject, and the device can adjust the rehabilitation training by itself. The processor can also generate a corresponding rehabilitation training adjustment program based on the preset device type and the evaluation result of the training intensity and send it to the corresponding device.

[0091] F max = max (F(t))…(1)

[0092] Among them, F max represents the maximum force; F(t) is the force detected at time t.

[0093] S=w1·θ flex +w2·θ ext +w3·θ left +w4·θ right …(2)

[0094] Among them, θ flex ,θ ext ,θ left ,θ right are the angles of forward flexion, backward leaning, left tilt and right tilt respectively; w1, w2, w3, w4 are the corresponding weight coefficients; S is the posture score.

[0095] Preferably, the weight coefficient can be determined according to the neck injury type or the neck injury muscle position, such as the neck disease and injury position detailed weight table shown in Table 1.

[0096] Table 1

[0097]

[0098]

[0099] Among them, F mean and F std It is the mean and standard deviation based on population statistics; G is the functional grade.

[0100] Based on the functional grade G and the posture score S, the rehabilitation training intensity evaluation index Training Intensity for adjusting the neck physical therapy program is generated in combination with formula (4).

[0101]

[0102] Where k is the calibration factor for training intensity, G max Is the highest functional classification; S max It is a standardized posture.

[0103] The rehabilitation training intensity evaluation index can be used to guide rehabilitation equipment to adjust the rehabilitation level. The rehabilitation training intensity evaluation index can also be used to assist medical staff in judging and treating the subject's neck pain problem.

[0104] According to a preferred embodiment, the rehabilitation device can be a cervical resistance training device, which includes parameter adjustment of training time and training resistance.

[0105] The training resistance range of the equipment is from R min to R max , the parameter adjustment of training resistance is shown in formula (5):

[0106] R=R min +Training Intensity×(R max -R min )…(5)

[0107] Among them, R is the equipment resistance adjusted according to the rehabilitation training intensity evaluation index (or the result representing the maximum training intensity that the subject can accept).

[0108] The training time range of the device is from T min to T max , the parameter adjustment of training time is shown in formula (6):

[0109] T=T max -Training Intensiyt×(T max -T min )…(6)

[0110] Wherein, T is the equipment usage time adjusted according to the rehabilitation training intensity evaluation index (or the result representing the maximum training intensity that the subject can accept).

[0111] Example 4

[0112] The hardware configuration of this embodiment is consistent with that of the previous embodiment, and only improvements are made in data collection and processing. The evaluation method provided in this embodiment is suitable for subjects who receive neck biomechanical function adaptability training.

[0113] For patients with weak biological functions of some neck muscles, or patients with cervical disc herniation, neck muscle strain or cervical arthritis, the neck with poor stability and functionality may affect the patient's posture, range of motion and daily activities, such as turning the head, lowering the head or looking up the head, etc., which will also cause the patient to further aggravate the muscle use error of the neck in daily exercise and life and aggravate the condition. Therefore, it is not only necessary to pay attention to the strengthening of the neck strength, but also the stability and functionality of the neck should be included in the evaluation criteria. This embodiment is based on the force detection of the subject's posture and different postures to obtain the left-right symmetric difference parameters of the shoulder and neck of the subject, the neck bending angle parameters, the neck rotation angle parameters, the neck maximum force parameters and the neck maximum force parameter holding time parameters. Based on the collected parameters, the processor can accurately detect the sagittal plane activity ability, cervical vertebrae myokinetics orientation and cervical axial stability of the subject's cervical spine, so as to carry out targeted rehabilitation training for the muscle groups of different depths and positions of the subject's neck.

[0114] Preferably, the sagittal plane activity of the cervical spine is confirmed based on the maximum force parameter and the maximum force parameter holding time collected by the muscle strength detection module 100 and the neck flexion and extension angle parameter collected by the posture detection module.

[0115] Preferably, the cervical vertebrae kinematic orientation is determined based on the maximum force parameter and the maximum force parameter holding time collected by the muscle strength detection module 100, the shoulder and neck symmetry index value collected by the posture detection module, and the neck rotation angle.

[0116] Preferably, the axial stability of the cervical spine is confirmed based on the maximum force parameter and the maximum force parameter holding time collected by the muscle strength detection module 100, the shoulder and neck symmetry index value collected by the posture detection module, and the neck flexion and extension angle.

[0117] Cervical spine kinesiology orientation LR The evaluation formula is shown in formula (7).

[0118]

[0119] Among them, F max is the maximum force parameter currently measured; Fp rev is the maximum force parameter measured most recently; T hold The holding time of the current maximum force parameter; T prev is the holding time of the most recent maximum force parameter measured; S sym is the current shoulder and neck symmetry index value; S standard is the ideal symmetry index value; A rot is the rotation angle currently detected; A target is the normalized rotation angle; w L 、w R 、wA They are the weighting coefficients of the maximum force parameter, the maximum force parameter holding time and the rotation angle respectively.

[0120] The weighted coefficient reflects the influence of each factor on the cervical vertebrae kinesiology orientation. Preferably, the weighted coefficient is classified into different categories according to the disease type and / or injury location, as shown in Table 2.

[0121] Table 2

[0123] Cervical sagittal plane mobility AR The evaluation formula is shown in formula (8).

[0124]

[0125] Among them, A bend is the current detected neck flexion and extension angle; A target is the standardized neck flexion and extension angle; w A′ is the weighting coefficient of the flexion and extension angle.

[0126] Cervical axial stability ST The evaluation formula is shown in formula (9).

[0127]

[0128] Based on the performance of the neck in different activities, the three original evaluation values ​​E LR 、E AP 、E ST Substitute into formula (10) to obtain the comprehensive score C of the patient's neck.

[0129]

[0130] Among them, E standard，i Indicates the standard value corresponding to each original evaluation value; is the maximum value of the standard deviation in the three evaluation directions; Indicates the standard deviation of the evaluation direction corresponding to the current operation. Preferably, the subject can repeat the same test behavior three times for Calculation.

[0131] Professionals in related fields can search and refer to various channels or resource libraries to obtain the standard values ​​required for the mobility, axial stability or kinesiology orientation of the cervical spine in the sagittal plane. These standard values ​​include E LR Standard value, E AP Standard value, E STStandard value, standardized neck flexion and extension angle, ideal symmetry index value and standardized rotation angle. In this embodiment, the required empirical data can come from the medical record database within the hospital and the public medical record database of the relevant departments that have been desensitized, such as electronic health record (EHR) data. In addition, these parameters can also be determined by clinical guidelines and standards, or by a large amount of reference data provided by standardization organizations and certification bodies. Certain functions or parameters in the formula can be adjusted according to clinical experience, medical literature or professional guidelines in specific circumstances. For example: Forensic Identification Technical Specifications (SF / ZJD0103003-2011) stipulate that the standard neck range of motion for healthy people is: 35°~45° forward flexion; 35°~45° backward extension; 45° left and right flexion each; 60°~80° left and right rotation each.

[0132] By comparing the comprehensive score C with the standard interval value, the processor can generate a corresponding neck physical therapy program adjustment instruction. Preferably, when the comprehensive score C is lower than the first threshold, the processor is configured to: retrieve the original evaluation value E corresponding to the current comprehensive score C LR 、E AP 、E ST , based on the above functional differences of the subject's cervical spine sagittal plane mobility, cervical spine axial stability or cervical spine kinesiology orientation compared with the healthy cervical spine, a corresponding cervical physical therapy program adjustment instruction is generated. More preferably, when the original evaluation value E LR 、E AP 、E ST One or more of them is less than the previous original evaluation value E LR 、E AP 、E ST When the cervical spine function optimization treatment mode generated by the processor includes the treatment for less than the last E LR 、E AP or E ST E LR 、E AP or E ST For example, the original evaluation value E currently obtained ST Less than the last original evaluation value E ST , the processor generates a first instruction. The first instruction is used to adjust an indicator related to improving the axial stability of the cervical spine in the cervical physical therapy program. The indicator related to improving the axial stability of the cervical spine is the cervical static resistance. "Adjusting the cervical physical therapy program" means changing various training parameters in the cervical physical therapy program, such as the maximum range of motion of the neck and the cervical static resistance, in a manner that promotes positive changes in the sagittal plane mobility of the cervical spine, the axial stability of the cervical spine, or the kinesiology orientation of the cervical spine. Preferably, when the original evaluation value E AP Less than the last original evaluation value EAP The maximum range of motion of the neck decreases. The reduction in the maximum range of motion of the neck can be referred to the maximum range of motion of the previous neck movement.

[0133] When the comprehensive score C is higher than the first threshold, the processor is configured to: send an instruction to the device providing neck physical therapy for the subject to maintain the current training mode. When the comprehensive score C is higher than the second threshold, the processor is configured to: retrieve the last and current E LR 、E AP or E ST , and compare them.

[0134] Preferably, when E ST When the parameter is increased, the processor is configured to increase the static resistance of the neck in the neutral position. LR When the parameter is increased, the processor is configured to increase the static resistance of the neck when the cervical spine rotates in the vertical axis direction. AP When the parameter is increased, the processor is configured to reduce the static resistance of the neck in the flexion and extension state of the cervical spine. The single increase in the static resistance of the neck is, for example, 2N.

[0135] Preferably, when E ST When the parameter is increased, the processor is configured to reduce the maximum range of motion of the neck in the neutral position. LR When the parameter is increased, the processor is configured to reduce the maximum range of motion of the cervical spine in the state of rotational movement along the vertical axis. AP When the parameter is increased, the processor is configured to reduce the maximum range of motion of the cervical spine in the flexion and extension state. The single reduction range of the maximum range of motion is, for example, 5°.

[0136] For patients with neck diseases or postoperative rehabilitation training of the neck, neck movements with a larger amplitude may cause further injury or aggravate the condition. Therefore, the neck physical therapy of this system emphasizes static resistance training and single rotation stretching static holding. In terms of safety, static resistance training and single rotation stretching static holding can effectively reduce the risk of injury and avoid discomfort or injury caused by sudden or large movements, especially in the postoperative rehabilitation stage, when the patient's neck stability and strength have not yet fully recovered. In terms of stability recovery, static training helps to enhance the strength of deep muscles, improve the supporting ability of the neck, and promote the recovery of muscle function. In terms of progressive training, static resistance training and stretching can be used as part of progressive training. After the patient gradually adapts, the range of motion and intensity are adjusted according to the rehabilitation process to ensure the effectiveness and safety of the rehabilitation process. Therefore, this embodiment specifically provides a neck rehabilitation training system that can adjust static neck movements.

[0137] More preferably, when ELR 、E AP or E ST In order to avoid neck muscle damage during the physical therapy program, the system can reduce the maximum range of motion of the neck while increasing the static resistance of the neck. This can increase the strength of the neck muscles while reducing the range of motion of the neck. LR 、E AP or E ST When the part in the neck shows an increasing trend, in order to increase the range of motion of the neck or increase the training of neck flexibility, and also to avoid damage to the neck muscles during the initial physical therapy program to increase the range of motion, the system can increase the static resistance of the neck while reducing the maximum range of motion of the neck.

[0138] Example 5

[0139] The hardware configuration of this embodiment is consistent with that of the above-mentioned embodiment, and only improvements are made in data collection and processing.

[0140] The muscle strength detection module 100 obtains the maximum force of the subject's neck extensor muscles when they are in isometric contraction, and the processor 200 generates corresponding health guidance suggestions based on the functional classification corresponding to the data representing the subject's maximum force fed back by the muscle strength detection module 100. Preferably, the processor 200 can infer the subject's potentially damaged muscle groups through the subject's occupation and the subject's posture information collected online, and generate corresponding evaluations in combination with mechanical data.

[0141] The subject sits against the first force-bearing part 130 and the second force-bearing part 140. The neck drives the head to stretch the neck backward, and the first force-bearing part 130 applies the same force to the subject's headrest to counteract the movement. The sensor part 150 collects the force generated by the subject on the first force-bearing part 130.

[0142] When the data characterizing the maximum force exerted on the subject is within the third range, the processor 200 obtains the subject's occupational information (office clerk) and generates a corresponding exercise pattern based on the normalized posture (long-term shrug) corresponding to the occupational information stored in the database.

[0143] The exercise mode includes a first general physical therapy mode of neck flexion and extension and rotation, a second general exercise mode including neck resistance exercise, and a cervical spine function optimization treatment mode cross-cutting with the first general physical therapy mode and the second general exercise mode. The severely damaged muscle group corresponding to the normalized posture of the subject is the trapezius muscle, and the cervical spine function optimization treatment mode includes neck rotation movements for exercising the trapezius muscle.

[0144] Specifically, the exercise mode includes the following steps:

[0145] Standard neck rotation 40 times / set, 10 sets per day;

[0146] Standard neck flexion and extension 20 times / group, 10 groups per day;

[0147] Each set of neck resistance exercise should be performed for 10 seconds, and 10 sets should be conducted each time. You can rest for 10 seconds between sets. The exercise sequence is to repeat the neck resistance exercise for one set after completing one circle of neck movement.

[0148] Preferably, the method of using the neck resistance exercise is that the subject crosses his hands behind the head, stretches the head and neck backward with maximum force, and resists forward with both hands with the same force, so that the two forces counteract each other and the cervical spine is in a neutral position.

[0149] At the same time, the processor 200 will also generate the following suggestion: See a specialist promptly when symptoms related to cervical spondylosis appear.

[0150] Preferably, the method of using the neck resistance exercise can also be that the subject uses the muscle strength detection module 100 to press against the first force-bearing part 130 and stretch the head and neck backward with maximum force.

[0151] Preferably, when the data characterizing the maximum force exerted by the subject is in different ranges, the duration of the exercise program can be different. When the data characterizing the maximum force exerted by the subject is in the first range and the second range, the generated exercise program lasts for 4 weeks, and when the data characterizing the maximum force exerted by the subject is in the third range, the generated exercise program lasts for 8 weeks.

[0152] When the data representing the maximum force of the subject is within the first range, the processor 200 generates a first general physical therapy mode including neck flexion and extension and rotation. The first general physical therapy mode includes standard neck left and right rotation 20 times / group, 10 groups per day; standard neck flexion and extension 20 times / group, 10 groups per day.

[0153] like Figure 5 As shown, the first force-bearing part 130 is connected to the box body 160 via a twisting part, so that the first force-bearing part 130 can rotate relative to the box body 160 .

[0154] When the subject exercises the neck with the help of the neck muscle group force measuring unit 120, the first force bearing part 130 of the neck muscle group force measuring unit 120 can be controlled by the subject's neck and rotate synchronously with the subject's neck to detect the rotation angle of the subject's neck. The largest rotation angle of the subject in the first three times is used as the benchmark for standard left and right neck rotation, and the neck rotation action not less than the benchmark is recorded as the standard left and right neck rotation.

[0155] According to a preferred embodiment, when the data characterizing the maximum force exerted on the subject is within the second range, the processor 200 obtains the subject's occupational information (assembly line product safety officer) and generates a corresponding exercise pattern based on the normalized posture (shaking the head left and right) corresponding to the occupational information stored in the database.

[0156] The training mode includes a first general physical therapy mode of neck flexion and extension and rotation and a cervical vertebra function optimization treatment mode interlaced with the first general physical therapy mode. The severely damaged muscle groups corresponding to the normalized posture of the subject are the splenius capitis and the splenius cervicis, and the cervical vertebra function optimization treatment mode includes neck extension movements for the splenius capitis and the splenius cervicis.

[0157] Specifically, the exercise mode includes the following steps:

[0158] Standard neck rotation 20 times / set, 10 sets per day;

[0159] Standard neck flexion 20 times / set, 10 sets per day;

[0160] Standard neck extension 40 times / set, 10 sets per day. The exercise sequence is to repeat the standard neck extension exercise once after completing each circumferential neck movement.

[0161] When the subject exercises the neck with the help of the neck muscle group force measuring unit 120, the standard neck extension movement is that the first preset force is applied to the first force-bearing part 130 when the neck is tilted back. When the subject exercises the neck with the help of the neck muscle group force measuring unit 120, the standard neck flexion movement is that the first force-bearing part 130 is not subjected to force when the neck is flexed forward.
