Description

Joint isometric muscle strength analysis method, device and computer readable storage medium

technical field

The invention relates to the field of intelligent medical treatment, and in particular to a method, device and computer-readable storage medium for analyzing isometric muscle strength of a joint.

Background technique

In clinical medicine, muscle strength refers to the ability of a muscle to generate a certain amount of tension in order to maintain posture, initiate or control movement when the musculoskeletal system is under load. The clinical assessment of muscle strength is the examination of the maximal contractile force of the relevant muscle or muscle group when muscle strength is significantly diminished or functional activity is compromised. Myasthenia is the reduction or absence of the ability of a muscle or muscle group to generate tension. Weakened muscle strength is commonly seen in lower motor neuron injury, primary myopathy, neurological disease, conditions that cause muscle disuse or prolonged immobilization such as burns, Arthritis, amputation, etc. can also cause decreased muscle strength. The measurement of muscle strength is an important part of the assessment of patients' limb function and rehabilitation. The detection of muscle strength can reflect the location and degree of muscle strength weakening, assist in the localization and differential diagnosis of soft tissue injury and neuromuscular injury, and guide the prevention of muscle strength imbalance. injury and deformity, and evaluation of the therapeutic effect after rehabilitation. Muscle contraction types can be divided into isometric and isotonic contractions, which in turn can be divided into eccentric and concentric contractions according to the direction of movement.

The current clinical isometric muscle strength analysis methods mainly include manual muscle strength measurement (MMT), equipment-assisted testing using hand-held dynamometers (HHD) and isokinetic dynamometers and other methods. Manual muscle strength measurement is the most commonly used method of muscle strength measurement in clinical practice. It is generally used to measure the maximum muscle strength of isometric contraction. During the measurement, the examiner makes the patient perform limb flexion and extension movements, and the examiner gives resistance from the opposite direction to test the patient's resistance to resistance. The strength of the overcoming, and pay attention to the comparison of the two sides. The results of the manual muscle strength test are generally expressed by the Lovett grading method. The muscle strength is divided into 6 grades, and can be subdivided into 14 sub-grades on this basis. However, the measurement of muscle resistance above grade 3 is completely dependent on the subject of the measurer. Therefore, the consistency between different measurers is low, and it is difficult to obtain accurate muscle strength values to complete the quantitative measurement. This analysis mode has a certain evaluation effect on patients with peripheral nerve paralysis and spinal cord injury, but it is not suitable for central For patients with paralysis and partial muscle damage, the evaluation significance is relatively limited. Isokinetic dynamometers are accomplished using large equipment. During exercise, the speed of limb movement is pre-set on the device, and no matter how much force the subject uses, the speed of limb movement will not exceed the set value. Using this system, the peak torque can be obtained, that is, the maximum force output during muscle contraction, the time and joint position of the peak torque, and the power during exercise, which can systematically and accurately evaluate the process of output torque during muscle movement. , but the equipment is expensive and the operation requires special training, so it is mostly used for sports injury rehabilitation and sports ability evaluation of professional athletes, and it is less used in clinical practice. Handheld dynamometers are somewhere in between the cost and convenience of measurement. The device is fixed to the measured limb through straps, boots, etc., and uses the inertial sensing module to indirectly reflect the maximum force of muscle activity. Compared with the manual test, it has higher consistency and repeatability, but there is also the problem that both testers and patients need to be trained before use. In addition, the test action requirements are very strict, and the results are greatly affected by the patient's movement mode, which also limits its clinical application.

At present, the prevalence of central paralysis, especially stroke, is increasing year by year in my country. The evaluation of its muscle strength and other motor functions is an important part of determining its rehabilitation quality plan. However, the existing joint isometric muscle strength analysis methods are due to the above Various reasons are unable to meet the actual needs.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In this specification, adjectives such as first and second may only be used to distinguish one element or action from another, and do not necessarily require or imply any actual such relationship or order. References to an element or component or step (etc.) should not be construed as limited to only one of the elements, components, or steps, but may be one or more of the elements, components, or steps, etc., where the circumstances permit.

In this specification, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in an actual proportional relationship.

Referring to FIG. 1, it is a flow chart of the method for analyzing isometric muscle strength of joints provided by the embodiment of the present application, which mainly includes steps S101 to S103, and the detailed description is as follows:

Step S101 : the pressure sensor outputs an electrical signal corresponding to the movement of the user's joint, wherein the pressure sensor is fixed in the vertical direction of the limb movement direction on one side of the target joint and close to the limb surface, and the target joint is the joint to be measured for isometric muscle strength of the user and locked at the angle to be measured.

A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. Since it can be suitable for various complex surfaces, and the size and shape can be flexibly adjusted, which is convenient for clinical operation, in the embodiment of the present application, the pressure sensor can be selected as a film pressure sensor. During use, a joint brace is used to lock the target joint (ie, the joint to be measured for isometric muscle strength of the user) at the angle to be measured. During the movement of the target joint driven by the muscle, due to the resistance of the joint brace, the muscle contracts isometrically, driving the limb to exert pressure on the pressure sensor, and the pressure sensor senses this pressure and outputs a corresponding electrical signal, such as a resistance value.

Step S102 : converting the electrical signal into the actual measured isometric muscle strength during joint movement of the user.

Since the pressure exerted by the limb on the pressure sensor has a linear relationship with the joint isometric muscle force, the joint isometric muscle force has a linear relationship with the electrical signal (for example, the resistance value) output by the pressure sensor, that is, the electrical signal is converted It is the measured isometric muscle strength when the user's joints move.

Step S103: According to a preset evaluation standard, an analysis result corresponding to the measured isometric muscle strength is obtained.

As an embodiment of the present application, according to the preset evaluation standard, obtaining the analysis result corresponding to the measured isometric muscle strength may be: obtaining the length of the distal limb to which the target joint belongs; according to the length of the distal limb to which the target joint belongs, the measured isometric contraction Muscle strength and preset evaluation criteria, estimate the maximum weight that the limb to which the target joint belongs when the movement direction of the target joint is perpendicular to the ground, and use this maximum weight as the analysis result of the isometric muscle strength of the user's joint. Due to its convenient operation, this solution can be used in practical scenarios such as labor capacity assessment, athlete training guidance and protection.

As another embodiment of the present application, obtaining the analysis result corresponding to the measured isometric muscle strength according to the preset evaluation standard may also be: according to the Lovett grading standard, converting the measured isometric muscle strength to the corresponding value in the Lovett grading standard Grading results, among which, the Lovett grading standard is obtained by linear regression between the equipment test results and the manual muscle strength measurement results of industry experts. Specifically, the acquisition process of the Lovett grading standard in the above embodiment is as follows: for the same joint angle of the same patient (which may be a patient with muscle weakness caused by different reasons, such as a stroke sequelae patient), the detection results of devices such as pressure sensors are compared with Perform linear regression on the freehand muscle strength measurement results of industry experts such as experienced physicians, obtain the linear relationship function between the freehand muscle strength measurement results of industry experts and the pressure sensor results, and obtain the Lovett grading standard directly converted from the pressure sensor results.

It can be seen from the method for analyzing the isometric muscle strength of the joints shown in Figure 1 above that the pressure sensor is fixed in the vertical direction of the movement direction of the limb on one side of the target joint and close to the surface of the limb. Output, which makes it possible to accurately measure the muscle strength of a specific angle of muscle movement, provide quantitative indicators, make up for the subjectivity of manual muscle strength measurement commonly used in clinical practice, and make the movement of the joint to be measured independent of other joints of the limb. Influenced by position and posture, more accurate results can be obtained.

The fixing device is used to fix the measuring device and fix itself on the limb on one side of the target joint. The measuring device is used to place pressure sensors on both sides of the end of the long bracket. The corresponding electrical signal is converted into the measured isometric muscle force when the target joint moves, and the analysis result corresponding to the measured isometric muscle force is obtained according to the preset evaluation standard.

It can be known from the multi-joint integrated measuring device provided by the above-mentioned application that the multi-joint integrated measuring device only includes a fixing device and a measuring device, wherein the measuring device only includes a long bracket and a pressure sensor, and the auxiliary tools are easy to find and have a relatively small volume. It is small, and the entire detection process is easy to operate. The detection can be completed by non-professionals or patients themselves, with high consistency and repeatability, and there are no requirements for the use site and environment.

As shown in Figure 3, it is a schematic diagram of a multi-joint integrated measuring device that can simultaneously measure the joint isometric muscle strength in two motion directions at a fixed angle. a strap. When the limb to which the target joint belongs is moving away from the long support, the difference between the readings of the pressure sensors on both sides of the long support is the target pressure, and the electrical signal corresponding to the target pressure is converted into the measured isometric muscle force when the target joint moves. , and then according to the preset evaluation standard, the analysis results corresponding to the measured isometric muscle strength are obtained. When using the multi-joint integrated measurement device exemplified in Figure 3 above, the base plate and strap can be placed at the target joint proximal or distal to the limb landmark (eg, 5 cm proximal to the cubital crease, proximal to the popliteal crease 5cm, etc.), the straps fix the base plate to the target joint side with appropriate tightness. According to the angle scales on both sides, adjust the long bracket to the corresponding angle position, lock the hinge, fix the long bracket, fix another strap to the corresponding position of the long bracket, and fix it around the other end of the limb to which the target joint belongs. At this point, the movable joint contacts the pressure sensor on the long brace, and the flexion or dorsiflexion force at that angle can be detected.

It should be noted that, if the multi-joint integrated measurement device shown in Figure 2 or Figure 3 is used to detect the joint isometric muscle strength at a fixed angle, for example, the wrist stability item in the Fugl-Meyer score, it can be simplified. Among them, the hinge and angle scale structure directly fixes the long bracket on the base plate at a specific angle. The structure is shown in Figure 4. This structure can be set on both sides of the limb, which is easier to operate and can be completed by the user independently.
