METHOD FOR RECOVERING MOTOR FUNCTION OF LIMB Russian patent published in 2019 - IPC A61H3/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to restoration of motor function of extremity. Disclosed is a method comprising fixing a rehabilitated extremity in a rehabilitation simulator apparatus configured to perform cyclic flexion and extension of a patient's extremity, for this purpose, during the session with the help of electrodes installed on the skin surface above the resting muscle that drives the limb, electromyographic signals are recorded with subsequent generation by the program module of control signals transmitted to the engine of the simulator for forced movement compensating for the missing strength of the rehabilitated extremity. Maximum, background and control electromyographic signals are recorded with the most intense, relaxed and intermediate tension during the muscle, coming into the program module, and generates control signals transmitted to the simulator engine in accordance with the value of the index determined based on the ratio of the detected electromyographic signals. Electromyographic signals are analyzed to obtain wavelet spectrograms characterizing distribution of amplitudes of said signals by frequencies at time intervals of not more than 0.2 s, in the frequency range from 10 to 2,000 HZ, and determining the integral value P, determined based on the ratio of electromyographic signals, for which subtraction of the value of each amplitude of the wavelet-spectrogram of the background signal from the amplitude-proportional amplitude of the maximum and control signals, division of difference of amplitudes of control and background signal by frequency difference of amplitudes of maximum and background signal by frequency, as well as summation of ratios of said differences of amplitudes to obtain a value of integral index P, in accordance with which program module 6 generates in real time signals correlated with muscular effort of patient.

EFFECT: invention provides recovery of muscular activity, increased rate of reaction, as well as muscular mass of patients, reduced spasticity and level of neuropathic pains.
