USE OF FEEDBACK IN STIMULATION OF MUSCLES OF THE MUSCULOSKELETAL SYSTEM IN THE SYSTEM OF AUTOMATIC MEASUREMENT OF MECHANICAL MECHANICS OF MUSCLE FIBER

Abstract

This paper considers the scheme of technical solutions that allow to form in the patient’s muscle tissue stimulating signals with a given amplitude, current and shape, while measuring the state of excitation of the muscle fiber and its deformation to ensure the best result. Schematic technical solutions, mathematical model, and possibility of application of these solutions in clinical practice in a complex of preventive and improving measures and rehabilitation and physiotherapeutic treatment are shown. The paper develops a new method of collecting data on the state of excitation of muscle tissues and calculating the parameters of excitatory signals during stimulation; the method of calculation of parameters of the signals used for stimulation is offered; developed a device for obtaining signals that characterize the state of excitation of muscle tissue and the simultaneous supply of stimulating signals; on the basis of the developed system the existing method of stimulation of muscles of the musculoskeletal system and control of their physiological condition is significantly improved. Using this method, it is possible to synthesize a system for automatically measuring the mechanical deformation of a muscle fiber, which would be fully described mathematically and modelled. Also, using the methods of analysis of automatic control systems, you can calculate the following parameters of the voltage of the stimulation signals: amplitude, frequency and phase; which will lead to the establishment of muscle tissue in a specific state of arousal or relaxation, which is calculated in advance, predicted and clearly controlled. And this is relevant when conducting a variety of physiotherapy activities in the sessions of therapeutic, preventive and rehabilitation medicine.
