Description
Technical Field
The application relates to the technical field of medical appliances, in particular to a sports rehabilitation system.
Background
Muscle atrophy or the propensity to atrophy of the extremities is a disease symptom of many complex diseases based on degenerative pathological changes, such as cervical spondylosis or elbow syndrome. Patients suffering from the diseases can suffer from upper limb muscular atrophy in the middle and early stages of the diseases, and the onset of myasthenia gravis is the limb muscles of the patients. Symptoms such as cerebral hypoxia accompanying the development of the disease, spinal cord lesions accompanying the muscular atrophy or partial atrophy of limbs, etc. gradually appear. Compared with the induction of diseases, long-term bedridden patients caused by comminuted fracture, paralysis and the like are also the causes of limb muscular atrophy.
In the prior art, for patients with improved physical state, acral muscle atrophy can be reversed by active or passive rehabilitation exercises. For the patient with weaker physical state, the progress of muscle atrophy can be slowed down through active or passive rehabilitation exercise, the life quality of the patient is improved, and the physical quality of the patient is enhanced.
With the progress of medical level, the means of active or passive rehabilitation exercise is also changed from manual pressing of a medical engineer or a patient family to the use of various medical auxiliary devices, and technologies and related devices used in the medical field are also gradually advancing. Patients with muscle damage in hospitals are generally treated in a later stage by adopting a device assisted rehabilitation training mode, and the using modes of the device are mainly a fixed mode and a mobile portable mode.
In the prior art, the rehabilitation exercise of the limb end of a patient is mainly divided into two parts, wherein one part is that the patient goes to a hospital by himself and takes exercise with the assistance of medical staff; the other is to exercise at home and by oneself in compliance with doctor's advice. The medical auxiliary instrument is not needed for home exercise or hospital exercise.
The Chinese patent with the patent number of CN109173180A discloses a wearable muscle rehabilitation exercise device, which comprises an upper clamping block, a first rubber air bag, a cloth belt, a lower clamping block, a second rubber air bag, a buckle, a connecting block, an arc plate, an arc sliding rail, a first sliding block and the like; the upper clamping block downside is equipped with first rubber gasbag, and both sides all are equipped with two strap around the upper clamping block, and lower clamping block top is equipped with the second rubber gasbag, and both sides all are equipped with the buckle around the lower clamping block.
Or, for example, chinese patent No. CN107518895a provides a rehabilitation training-oriented same muscle detection method for monitoring the progress of muscle rehabilitation training. The method comprises the steps of firstly decomposing acquired multichannel surface electromyographic signals to obtain a motion unit issuing sequence, secondly extracting motion unit issuing waveforms, then estimating the spatial position of the motion unit by utilizing the peak value of the motion unit issuing waveforms and the differential issuing waveforms, thereby determining the same muscle, finally observing the change of the same muscle in rehabilitation training, and adjusting a rehabilitation training plan.
The electrical stimulation method is also an effective passive exercise method for rehabilitation of atrophic muscles in an unhealthy state. The chinese patent CN107737404a, for example, relates to a neuromuscular electrical stimulation circuit for rehabilitation system and rehabilitation system. The neuromuscular electrical stimulation circuit of the rehabilitation system comprises a singlechip, an electrical signal regulating module and an output interface which are connected in sequence, wherein the electrical signal regulating module comprises a current regulating circuit and a voltage regulating circuit; the single chip microcomputer outputs PWM signals and control signals, the current regulating circuit receives the PWM signals and the control signals, current amplification is carried out on the PWM signals according to the control signals, the PWM signals after current amplification are transmitted to the voltage regulating circuit to carry out voltage amplification, and finally the PWM signals conforming to neuromuscular electrical stimulation are output through the output interface.
In the prior art, an extremity exercise medical device relying on subjective mobility of a patient or an automated rehabilitation training detection device generated based on the muscle state of the patient can only enable the extremity muscles of the patient to obtain a single exercise mode.
The constitution of the acro-muscle is complex, and the muscle tissue contains slow muscles which improve the endurance of the acro-muscle and fast muscles which influence the explosive force of the acro-muscle. Passive exercise or active exercise by means of electrical stimulation alone is not effective for the exercise purpose. In particular, prolonged electrical stimulation exercises can cause muscle numbness, reducing the patient's exertion under the innervation of the muscles of the patient; however, the long-time autonomous exercise may not only cause muscle strain due to the wrong posture exercise, but also have a problem that the upper limit of the autonomous exercise cannot be increased due to weak consciousness of the patient. Because of the lack of an effective method of guiding the patient to exercise autonomously, the exercise effect of the patient on the muscles after receiving the electrical stimulation is not optimal. Because the autonomous exercise after the electric stimulation does not reach the standard, the pain or itching and tingling sensation generated by the electric stimulation muscles can be aggravated while the rehabilitation effect is reduced, and the fear of patients to electric stimulation rehabilitation means is deepened.
Based on this, the present application provides a sports rehabilitation system. The system can alternately set an electric stimulation mode of passive exercise and a balloon compression mode of active exercise.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present application, the text is not limited to details and contents of all but it is by no means the present application does not have these prior art features, but the present application has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.
Disclosure of Invention
The acro-muscles are important muscle groups for maintaining the physical state of a patient, and for maintaining the patient's arms and arms to walk in daily life. Acro-muscular atrophy refers to a decrease in muscle volume caused by attenuation or even disappearance of muscle fibers, etc., and causes of such disorders include dysfunction of the nervous system, damage to the extremities, and long-term non-use of the acro-muscles, etc. When the patient suffers from the problems, medical staff can recommend the patient to perform rehabilitation training of the limb muscles, and the training can help the patient to maintain the fiber state (elasticity and diameter) of the current limb muscles; on the other hand, for the patient with possible rehabilitation, the function of the limb end can be recovered as soon as possible under the assistance of rehabilitation training, and the patient can return to the normal living state in time.
In the prior art, the rehabilitation training of the muscles of the extremities mainly depends on a single rehabilitation means. For example, electrical stimulation is used in the face of paralyzed patients, and mechanical exercise is used for patients who can exercise actively. In particular, the main purpose of muscle electrical stimulation (EMS) is to activate, exercise, motor muscle fibers; functional Electrical Stimulation (FES) is primarily aimed at compensating damaged muscle tissue, by the action of which the function of the damaged tissue is compensated; neuromuscular electrical stimulation (NMES) refers to the treatment of neuromuscular disorders by stimulating nerves or muscles with low frequency pulsed currents, causing muscle contraction, and improving muscle function. The instrument is typically a pressing device that clamps onto the patient's arm or leg or a pulling device that is hooked onto the patient's arm or leg.
In the actual treatment process, the application finds that if the sensation at the limb end of the patient is not disappeared (for example, athletes recovering muscle strength and patients with disuse atrophy) when the patient is subjected to uninterrupted electric stimulation treatment for a long time, the electric stimulation of the electrode slices is contacted with the patient for a long time, so that itching and even stinging sensation can be generated at the contact position, and the sensation is one of the reasons for seriously influencing the follow-up treatment of the patient for some patients with weak stamina (or patients with the limb end atrophy which do not influence the life of the patient and are easy to discard).
The exercise mode in the prior art can enable the problem that the lactic acid is accumulated in the muscle of a patient all the time in the exercise process, the pain still exists in the exercise of the patient, and the muscle in the fatigue state has poor effect in the process of autonomous exercise or passive exercise. The tired feel of the muscles is difficult to recover in a short time (or a large amount of lactic acid accumulated in the muscles is difficult to be treated in a short time) in a single exercise, so that the patient exhibits poor effects in exercise on a day-to-day basis. For patients with poor muscle strength, electrical stimulation-cryotherapy-voluntary exercise-cryotherapy-electrical stimulation may cause the muscles to form an exercise cycle with the periods of excitement being in a non-tired state throughout, and the muscles are in an excited state in a non-tired state throughout when exercising. The exercise mode reduces the feeling of itching and tingling caused by long-time electric stimulation and achieves the aim of non-invasive exercise.
Related studies have demonstrated that prolonged use of neuromuscular electrical stimulation locally may result in decreased neuromuscular sensitivity in the local muscles of the patient and reduced patient's ability to innervate the muscles.
Aiming at the defects of the prior art, the application provides a sports rehabilitation system. The exercise rehabilitation system comprises: a rehabilitation training module and a remote server capable of providing a patient with a first exercise mode under passive exercise and a second exercise mode under active exercise. The rehabilitation training module comprises a signal acquisition unit capable of acquiring myoelectric signal parameters, wherein when the state of the muscle with dysfunction of a patient, which is fed back by the myoelectric signal detected by the signal acquisition unit, changes, the muscle is controlled by the remote server, and the rehabilitation training module can be switched between a first exercise mode and a second exercise mode, so that the muscle with dysfunction of the patient can be always in a non-fatigue state in the process of exercising the muscle function intensity and exercising the neuromuscular control intensity in a crossing way.
The beneficial effects of this technical scheme:
(1) The system is provided with two modules, passive exercise and active exercise, using electrical stimulation of the muscles, the distribution of the muscles in the two modules being controlled by the device and the patient, respectively. In the actual use process, when the electro-stimulation method generates bad feeling (mainly the muscle enters the tired period, and the muscle in the tired period can generate a large amount of lactic acid to increase the feeling of itching and stinging of the muscle), the system can switch the exercise mode based on the feedback of the electromyographic signal parameters.
For patients with muscle injury, the system adopts a passive exercise-cold therapy-active exercise mode to treat as the muscle strength is at a normal level.
For patients suffering from muscular atrophy caused by prolonged bedridden patients, the system adopts a passive exercise-active exercise mode for treatment.
The second exercise unit is arranged based on an alternating exercise pattern of squeeze muscles and muscle contractions, the rhythm and strength of such movements being controlled by the patient. On the one hand, the exercise mode controlled by the patient can lead the patient to reduce the frequency based on the body feeling, not only can avoid the further stimulation of the current to the skin surface layer, but also can reduce the tired feeling of the muscles or lead the intensity of the muscle exercise to be in the controllable degree of the patient; on the other hand, the active exercise of the electrically stimulated muscles and the patient based on their own sensations is different, in particular with respect to the mastering forces of the innervating muscles. The electrical stimulation method is an exercise mode of the nerve-control muscles, and the patient actively exercises himself as an exercise method of the nerve-control muscles. Through the alternate implementation of the two modes, the upper limit of the muscle exercise intensity can be improved, the regulation and control dominance capacity of the brain nervous system of the patient on the muscle of the exercise part of the patient can be enhanced, and more muscle movement units are promoted to participate in or cooperate with exercise.
(2) The active exercise method of the extremity is generally set for the portion of the exercise required by the patient. During this exercise, the patient needs to complete a specific part of the muscle contraction movement under the control of his own brain. However, in the prior art, the limbs of a patient who has completed the electrical stimulation treatment in a hospital may exhibit numbness, itching, etc. that affect the perception of muscle movement by the patient, and such sensation does not disappear for a period of several hours or even one day. Under the interference of such sensations, a patient may perform active exercise on wrong muscle parts during active exercise, for example, the patient may control the supinator to drive the extensor longus muscle of the lateral wrist to contract by mistake during active exercise of the deep flexor muscle of the forearm, and the patient cannot accurately distinguish between the two muscle contraction positions during active exercise due to numbness of the muscle groups of the forearm after receiving the electrical stimulation, so that the patient maintains an erroneous active exercise mode for a long time in a home environment.
The present system is capable of providing a personalized customized exercise pattern based on the patient's acromioclavicular group. Compared with the prior art that the exercise method is changed according to the doctor's advice after the patient goes to the hospital for each time, the system can be remotely connected with the medical staff terminal, the doctor can timely change the exercise method based on the electromyographic signal parameter change of each exercise of the patient, and the exercise method mainly modifies the judgment standard of the instrument without the patient to memorize by himself, so that each exercise of the patient is ensured to be completed under the correct guidance and assistance of the system.
According to a preferred embodiment, the remote server is capable of receiving the myoelectric signal parameters of the patient's dysfunctional muscles detected by the signal acquisition unit and judging the state of the patient's dysfunctional muscles based on the myoelectric signal parameters, wherein the remote server switches the rehabilitation training module to the cold therapy module when the patient's dysfunctional muscles enter a fatigue state based on the obtained time and frequency domains of the myoelectric signal parameters, so that the state of the patient's dysfunctional muscles in a non-fatigue state is changed from an excited period to a relaxed period.
The data for characterizing the state of the patient's extremity muscles at least comprises: myoelectric signal parameter frequency domain. Preferably, the electromyographic signal parameter frequency domain used to characterize the muscle state can be one or more of an integrated electromyographic value (IEMG), an average power frequency (MPF), or a Median Frequency (MF).
IEMG (μV) refers to the sum of areas surrounded by curves in unit time after the measured surface electromyographic signals are rectified and smoothed, and represents the total discharge amount of a movement unit when muscles participate in the movement in a certain time, and reflects the electromyographic movement intensity of the muscles in a certain time. The magnitude of the IEMG value reflects the magnitude of the electrical discharge and the number of muscle fibers per motor unit when involved in muscle contraction during exercise. Generally, the greater the IEMG amplitude, the greater the fatigue level. IEMG is an important index for evaluating muscle fatigue.
Median Frequency (Hz) Median Frequency (MF): the intermediate value of the discharge frequency, i.e. the intermediate value of the discharge frequency during muscle contraction, generally also tends to decrease as the movement time period increases. The MF values are different between skeletal muscles at different locations due to the different proportions of the fast and slow muscle fibers in the skeletal muscles. Fast muscle fiber excitation is manifested by high frequency discharge, and slow muscle fiber is manifested by low frequency.
Mean Power Frequency (Hz) average power frequency (MPF): refers to the average of the frequencies over the period of time. In the state of muscle fatigue, the surface myoelectricity frequency domain index MPF is in a decreasing change.
When the muscle enters a fatigue state, the integrated myoelectric value (IEMG) of the myoelectric signal increases, and the average power frequency (MPF) and the Median Frequency (MF) decrease.
For example, when the limb muscle changes from a tired state to a non-tired state, the frequency domain of the electromyographic signal parameters is characterized by: MPF increases significantly while IEMG changes in a decreasing fashion. In the present application, a significant decrease means that the rate of change of the amplitude assumes a negative value, and a significant increase means that the rate of change of the amplitude assumes a positive value. When the rate of change of MPF is unchanged, only in a sustained or intermittent decrease or increase, it indicates that the acral muscle is still in the current state and no state jump occurs.
The beneficial effects of this technical scheme:
setting different exercise modes for muscles in different states during the process of cross exercise is an effective means of lifting muscle exercise. According to the technical scheme, the muscle state can be intuitively reflected based on the electromyographic signal parameters, and the cold therapy module is provided for the patient based on the tired state and the non-tired state of the muscle, so that the muscle can be converted from the excitation period to the relaxation period when entering the tired state, and the damage of muscle congestion to the muscle is avoided.
The technical scheme also separates exercise modes based on the tired state and the non-tired state of the muscle, thereby improving the exercise efficiency of the muscle in each period.
Cold therapy is a method of reducing temperature by contacting the body with a hypothermic medium to relieve muscle damage. In the prior art, related researches prove that the cold therapy can relieve muscle pain, relieve muscle spasm and promote intramuscular vasoconstriction, and is beneficial to improving the blood circulation flow rate of muscles.
The technical scheme adopts an exercise method of passive exercise, cold therapy and active exercise. In the passive exercise process, the cold therapy can relieve itching and pain caused by the electrical stimulation to the patient, and can timely relieve the tired state of the muscles when the muscles are tired by the electrical stimulation.
According to a preferred embodiment, the remote server is configured to: the rehabilitation training module is controlled to enter a first exercise mode preferentially, so that the muscle with the dysfunction of the patient enters a state of passive exercise for exercising the functional strength of the muscle.
The beneficial effects of this technical scheme:
in the actual motor rehabilitation phase, the purpose of active exercise is to allow the patient to adapt to the increase in muscle or muscle function produced during passive exercise, i.e. the increased muscle mass through passive exercise requires that the patient be proficient in innervating that part of the muscle through active exercise.
Therefore, the exercise mode for the purpose of muscle function rehabilitation should take precedence over the passive exercise, and when the passive exercise produces side effects on the muscle, the module corresponding to the cold therapy or the active exercise is selected to be switched according to the actual situation.
The technical scheme increases the comfort of muscle function exercise of patients by means of preferential passive exercise and enables the system to be adapted to various patients (for example, normal persons with muscle injury or patients with muscle atrophy).
According to a preferred embodiment, the remote server is configured to: and when the myoelectric signal parameters of the muscle with dysfunction of the patient receiving the cold therapy of the cold therapy module represent that the muscle relaxation of the muscle with dysfunction of the patient is lower than the second level, controlling the cold therapy module to stop working and starting the rehabilitation training module in a dormant state, wherein the exercise mode of the rehabilitation training module after starting is different from the exercise mode of the rehabilitation training module before the rehabilitation training module enters the dormant state, as shown in fig. 2.
The beneficial effects of this technical scheme:
when the patient's muscle relaxes below level two, it is shown that the contraction of the muscle does not have an impact on the muscle itself, such as injury, upon re-exercise.
The present application makes it possible to determine muscle relaxation based on the muscle relaxation monitoring technique of the prior art. Such as single stimulus count (PTC) after tonic stimulation, by observing the number of responses caused by 16 single stimuli given after tonic stimulation. Based on clinical manifestations of PTC in the range of 0 to 10, it is considered that PTC is in a relaxed state when PTC is in the range of 7 to 9. At PCT less than 5, excessive muscle strength relaxation (or relaxation due to the action of external force drugs, as the case may be) is indicated. In the present application, muscle relaxation is classified into three classes, one class being PTC 10, indicating that the muscle is in an elastic or tight state. The second level is that PTC is in the range of 7-9, indicating that the muscle is in a relaxed state. Tertiary PTC is in the range of less than 7, indicating that the muscle is in an excessively relaxed state (muscle atrophy or relaxed by drug action).
According to a preferred embodiment, the rehabilitation training module comprises a first exercise unit applied in a first exercise mode and a second exercise unit applied in a second exercise mode, wherein the first exercise unit is capable of providing muscle electrical stimulation energy to the patient's dysfunctional muscle on the patient's dysfunctional muscle such that the patient's dysfunctional muscle is capable of passively exercising muscle functional strength through the rehabilitation training module in the first exercise mode.
According to a preferred embodiment, the second exercise unit exercises the patient's extremity muscles by squeezing the patient's dysfunctional muscles, which are dysfunctional muscles of the patient's extremity. The second exercise unit includes a bladder assembly capable of wrapping the patient's extremities to provide squeeze exercises and resistance exercises for the patient's dysfunctional muscles.
The second exercise unit further comprises an air flow control assembly in communication with the air bag assembly capable of providing air to the air bag assembly upon receipt of the instructions sent by the remote server and a pressure signal acquisition assembly disposed on an interior surface of the air bag assembly to sense pressure between the air bag assembly and the patient's extremities.
According to a preferred embodiment, when the second exercise unit is woken up, the remote server is configured to:
a second exercise pattern comprising an alternation of squeeze exercises and resistive exercises is generated based on the patient's extremity electromyographic signal parameters, wherein the remote server generates a force for adjusting the pressure generated by the bladder assembly during squeeze exercises and the resistance generated during resistive exercises when the first exercise unit is deactivated and the signal acquisition unit detects electromyographic signal parameters indicative of the start of movement of the patient's extremity muscles.
The beneficial effects of this technical scheme:
squeeze exercise is a training method that uses elastic bands or other elastic devices to exert pressure on the muscles, increasing the tension and endurance of the muscles. Resistive exercise is a training method that applies resistance to muscles, increasing the strength and volume of the muscles. The application applies exogenous interference to the muscle through two dynamic changes of the contraction of the muscle so as to increase the exercise efficiency of active exercise.
According to a preferred embodiment, the pressure is provided by the balloon assembly in a first state when inflated and the resistance is provided by the balloon assembly in a second state when deflated, as shown in fig. 1.

Preferably, the second exercise unit provides the patient with corresponding preset pressure and resistance in a physician-ordered manner when performing the squeeze exercise for the first time.
According to a preferred embodiment, the resistive exercise is: when the wake-up unit prompts the patient to perform voluntary conscious acro-muscular exercise, the air bag assembly in the second state limits the space required by the patient acro-muscular in the contracted state to resist the tension of the patient acro-muscular, wherein the resistance value of the resistive exercise is generated by the remote server based on the pressure value provided by the pressure signal acquisition assembly when the resistive exercise was last performed.

Passive exercise refers to the passive reception of movement by a patient by means of manipulation by another person, thereby achieving the purpose of muscle function enhancement.
Active exercise refers to the patient completing various forms of movement by means of self-neuromodulation to achieve the goal of increasing muscle tone and the patient's innervating muscle strength.
Dysfunctional muscles refer to muscles that for a variety of reasons lose some or all of their normal function. For example, a patient with a fracture has its acro-muscular atrophy in a long-term bedridden state, so that its acro-muscular is unable to support the body for walking.
Muscle function strength exercise refers to an exercise method for exercising muscle functions, such as a method for exercising muscle strength, endurance, and the like.
Neuromuscular control intensity exercise refers to exercise a person's own ability to control muscles, particularly for long-term bedridden patients, whose ability to innervate muscles is reduced, although the patient's extremity muscles remain intact by external forces during bedridden, resulting in uncontrolled functioning of the patient's muscles during use.
The fatigue state refers to the problem that muscle weakness, muscle spasm, or slow down of nerve signal feedback and other symptoms occur due to lactic acid accumulation and the like during passive exercise or active exercise, and muscle in the state cannot improve muscle function in the continuous exercise process, and muscle injury is easy to occur.
The frequency domain of the electromyographic signal parameter refers to an index used to characterize the state of the muscle. In the prior art, a decrease or increase in the frequency domain of the electromyographic signal parameters can be used to characterize whether a muscle enters a state of fatigue.
The excitation period refers to the condition of the muscles in congestion. Generally, the muscles in the excited stage are suitable for exercise because they can help the rupture and recombination of fibers in the muscles due to the rapid circulation of blood.
The relaxation phase refers to the muscle being in a relaxed state of relaxation. The blood flow speed of muscles in the relaxation period is reduced, but the digestion speed of harmful substances accumulated among muscle tissues is faster, and the muscles in the relaxation period can relieve muscle fatigue and increase muscle elasticity.
Example 1
This embodiment provides the use of the athletic rehabilitation system of the present application in exercising the extremities of a patient.
Based on the patient's limb muscle state, the healthcare worker presets in the present system the setting of the amount of electrical stimulation current and total duration for the current patient under electrical stimulation therapy. The first exercise unit 210 provides electrical stimulation therapy to the patient.
Based on the patient's state, the healthcare worker presets the flow of exercise through the patient's state. Taking a patient with a sport pull wound and a sportsman lying in bed for one week as an example, medical staff adopts a sport rehabilitation treatment method of passive exercise, cold therapy and active exercise.
The first exercise unit 210 is turned on to provide electrical stimulation therapy to the patient's calf muscles based on a preset program.
When the electromyographic signal parameter associated with the patient's calf muscle provided by the signal acquisition unit 300 characterizes the patient's calf muscle entering a tired state, the remote server 100 controls the first exercise unit 210 to be turned off and the cryotherapy module 700 to be turned on.
Preferably, the cryotherapy module 700 is a liquid nitrogen freezing device, which operates on the same principle as the liquid nitrogen freezing chamber of the prior art.
After the change of the myoelectric signal parameters associated with the tired state of the calf muscle in the relaxation period, the remote server 100 turns off the cold therapy module 700 and turns on the second exercise unit 220.
The second exercise unit 220 comprises a wake unit 400, which wake unit 400 prompts the patient to engage the second exercise unit 220 for voluntary conscious acro muscle exercises when the second exercise unit 220 is turned on. Preferably, the wake-up unit 400 comprises a voice prompt component and/or a display component. The display assembly begins to show a schematic diagram of the principle of acromioclavicular force. The wake-up component prompts the patient to change the exercise state in the form of voice, and the patient needs to exercise independently by matching with the equipment.
When the calf muscle enters a fatigue state, the frequency domain characteristics of the electromyographic signal parameters are as follows: MPF and MF increase significantly while IEMG changes progressively. When the calf muscle is changed from a fatigue state to a non-fatigue state, the frequency domain characteristics of the electromyographic signal parameters are as follows: MPF and MF decreased significantly while IEMG changed incrementally.
The calculation formula of IEMG is as follows:
wherein t is 1 To collect the myoelectric signal, t 2 For the end time of the acquisition of the electromyographic signals, the I A (t) I is the magnitude of the electromyographic signals.
The calculation formula of MPF is as follows:
wherein PSD (f) is power spectral density, MF is median frequency, f is electromyographic signal frequency, f 0 Is the upper frequency limit.
The formula of MF is as follows:
wherein PSD (f) is power spectral density, MF is median frequency, f is electromyographic signal frequency, f 0 Is the upper frequency limit.
Preferably, the second exercise unit 220 provides the patient with corresponding preset pressures and resistances in a physician-compliant manner when performing the squeeze exercise for the first time. For example, when the patient's acral muscle force is four, the air pressure of the air bladder can be 25kpa to 28kpa to provide the patient with an initial pressure. Meanwhile, when the patient contracts the muscle, in order to increase the resistance of the muscle during the expansion, the air pressure of the air bag can be 20kpa to 23kpa. During contraction of the muscle, the volume of the muscle increases in a short time due to a large amount of blood rushing to the target muscle, and this process is called pumping blood.
According to a preferred embodiment, the remote server 100 receives electromyographic signal parameters related to the variation of the muscle group of the calf muscle of the patient under the stimulation of the rehabilitation training module 200, the remote server 100 generates corresponding exercise modes, wherein the second exercise mode comprises at least an exercise mode a, an exercise mode B and an exercise mode C with differences in intensity and frequency of the squeeze exercise and resistance exercise based on the electromyographic signal parameters of the fast muscle of the extremity muscle of the patient.
Preferably, the muscle strength of the user's acromydriasis is classified into zero to five stages based on the muscle strength measurement. When the contraction of the acromydriasis of the user lasts for 0s, the muscle strength of the user is zero order; when the time lasts for 1s, the muscle strength is first-order; similarly, the muscle strength is five levels for 5 s. As the number of patient exercises increases, muscle endurance decreases, and thus, the muscle strength judgment in the present application is dynamically changed.
Preferably, during each exercise, the remote server 100 is able to re-evaluate the muscle strength of the current acro-muscle based on the contracted retention time of the patient's acro-muscle group or of a certain acro-muscle tissue, the muscle strength evaluation criteria referring to the prior art evaluation of the muscle strength for the next generation of resistance. For example, when the initial first pressure value is used by a five-level muscle force patient, the first pressure value of a patient with a four-level muscle force is an initial first pressure value of 4/5. When the patient muscle force is three levels, the first pressure value is an initial first pressure value of 3/5. When the patient muscle force is of the second order, the first pressure value is an initial first pressure value of 2/5. When the patient muscle force is at one level, the first pressure value is an initial first pressure value of 1/5.
For example, when the user's muscle contraction remains for more than 5 seconds, the remote server 100 receives the resistance parameter transmitted by the pressure signal acquisition assembly 600 to generate a first resistance value. Based on the status classification of the user's acro-muscle groups, the remote server 100 generates a first pressure value for the balloon assembly 500 and the extremities. The balloon assembly 500 is inflated until the pressure between its surface and the acro-skin reaches a first pressure value. Preferably, the resistance is 3/5 of the pressure.
According to a preferred embodiment, the electromyographic signal parameters used to evaluate the subsequent exercise mode can be referenced to the state of the muscle at the time of the electrical stimulation exercise. Preferably, the signal acquisition unit 300 detects a myoelectric signal parameter related to the fast muscle in which the muscle contraction occurs under the stimulation of the rehabilitation training module 200, when the myoelectric signal parameter is lower than x 1 In the meantime, the remote server 100 generates the exercise pattern a and transmits an instruction to the second exercise unit 220 when the second exercise unit 220 is turned on. When the electromyographic signal parameter is x 1 ～x 2 When within range, the remote server 100 generates an exercise pattern B and sends an instruction to the second exercise unit 220 when the second exercise unit 220 is turned on. When the electromyographic signal parameter is higher than x 2 In the meantime, the remote server 100 generates the exercise pattern C and transmits an instruction to the second exercise unit 220 when the second exercise unit 220 is turned on. Preferably, x 1 40. Mu.V. X is x 2 55. Mu.V.
The second exercise mode actually comprises: alternating squeeze exercises and anti-resistance exercises, wherein the speed of the squeeze exercises and anti-resistance exercises can be used to exercise the patient's fast muscles, and the intensity of the squeeze exercises and anti-resistance exercises can be used to exercise the patient's slow muscles. Specifically, the rate at which the balloon assembly 500 is inflated (or reaches a first pressure value per unit time) and deflated (or reaches a first resistance value provided by the patient per unit time) can quickly prompt the patient to contract the muscles and increase the rate at which the muscles pump blood, thereby achieving the goal of exercising the fast muscles. The pressure value of the inflation of the air bag assembly 500 and the resistance value formed by the deflated air bag assembly on the muscles of the patient can bring auxiliary effects to the muscle strength exercise of the patient, so that the purpose of exercising the slow muscles is achieved. For example, the airbag module 500 can reach a gas pressure of 28kpa within 1s and reduce the gas pressure to 20kpa within 1 s.
Exercise mode a is: the number of times of alternately performing the squeeze exercise and the resistance exercise is a 1 The first pressure value is b 1 The first resistance value is c 1 。
Exercise mode B is: the number of times of alternately performing the squeeze exercise and the resistance exercise is a 2 The first pressure value is b 2 The first resistance value is c 2 。
Exercise mode C is: the number of times of alternately performing the squeeze exercise and the resistance exercise is a 3 The first pressure value is b 3 The first resistance value is c 3 。
According to a preferred embodiment, a 1 <a 2 <a 3 。b 1 <b 2 <b 3 。c 1 <c 2 <c 3 。
According to a preferred embodiment, the number of exercises in the different modes, the initially set pressure value and the initially set resistance value are all set based on the judgment of the health care provider about the muscular state of the patient.

According to a preferred embodiment, the first exercise unit 210 comprises a plurality of electrodes 800, wherein the plurality of electrodes 800 are disposed on the inner surface of the balloon assembly 500, the electrodes 800 comprise a first microelectrode 810 and a second microelectrode 820, and the voltage between the first microelectrode 810 and the second microelectrode 820 is the discharge voltage of the electrodes 800, as shown in fig. 3.
