Description

Gastrocnemius motion parameter visual measurement method based on ultrasonic tissue Doppler Technical Field The invention relates to the technical field of gastrocnemius muscle strength measurement, in particular to a gastrocnemius muscle motion parameter visualization measurement method based on ultrasonic tissue Doppler. Background The gastrocnemius muscle is used as a core muscle group at the rear side of the lower limb and plays a key role in walking, namely, a ground pedaling pushing force is provided by contraction during walking, the body is kept in vertical balance, the muscle strength directly influences the movement efficiency and the explosive force during running, jumping and other dynamic movements, and the activities of daily activities such as ascending and descending stairs, standing up and the like also depend on the gastrocnemius muscle and soleus muscle to cooperatively exert force. The gastrocnemius muscle strength measurement method has important values in clinical fields, can assist diagnosis and lesion localization of neuromuscular diseases such as cerebral apoplexy, spinal cord injury and sarcopenia, for example, the gastrocnemius muscle strength of a cerebral apoplexy patient is reduced and is often accompanied with spasm, the nerve injury range can be judged through muscle strength evaluation, the condition change can be dynamically monitored, for example, periodic muscle strength detection of a sarcopenia patient can track the muscle loss speed, the treatment and rehabilitation training scheme formulation can be guided, the resistance of a rehabilitation instrument is adjusted according to the recovery degree of the muscle strength, the training action is optimized, and meanwhile, the muscle strength level is a core index for evaluating the prognosis and life ability of the patient, and a person with the qualified muscle strength can more easily realize independent walking, so that the falling risk is reduced. In the field of sports, gastrocnemius muscle strength measurement can evaluate the capability of muscles, monitor the fatigue state of the muscles after sports, judge the recovery time according to the strength decline degree, early warn whether the sports are limited or injured risk caused by the deficiency of gastrocnemius muscle strength, timely find early sports injury such as muscle strength asymmetry caused by over training, evaluate the training effect, compare the gastrocnemius muscle strength change of different training periods to verify the effectiveness of a training scheme, and provide data support for the establishment of a personalized training plan of an athlete, such as designing targeted strength training according to the gastrocnemius muscle explosive force characteristics of a sprint runner. At present, the gastrocnemius muscle strength measurement multi-dependence indirect assessment method can reflect the muscle strength state to a certain extent, but has obvious limitations that electromyography measurement indirectly correlates muscle strength by recording parameters such as electromyographic signal peak value, frequency and the like, but signals are easy to be interfered by skin states and electrode placement positions, the muscle strength cannot be directly quantified, the ratio Hmax/Mmax of the H wave peak value and the M wave peak value of the tibial nerve reflection reflects the excitability of spinal cord anterior angle motor neurons, the method is mainly used for spasticity assessment and is difficult to accurately correspond to the actual muscle strength level, the pace test indirectly deduces the gastrocnemius muscle function through the walking speed of 6 meters, the specific is lower due to factors such as gait habit, balance capability and the like of a subject, the balance and motor function scales such as the gastrocnemius comprehensive spasticity scale score CSS depend on subjective scores, the result consistency is easy to be influenced by experience of an evaluator, and the dynamic change of the muscle strength cannot be captured. The common short plate for the methods is that the muscle strength change in the gastrocnemius contraction process can not be visualized and monitored in real time, and the requirements of clinical instant evaluation of the state of illness and dynamic monitoring of muscle functions in sports scenes are difficult to meet. Disclosure of Invention In order to overcome the defects of the prior art, the invention aims to provide a gastrocnemius movement parameter visualization measurement method based on ultrasonic tissue Doppler, which solves the problems that the prior method cannot directly quantify the muscle strength and dynamically monitor in real time, is difficult to accurately correspond to the actual muscle strength level and depends on subjective scores.
