Background technique

In 1967, Miller et al. proved that the activities of the autonomic nervous system, such as heart rate, blood pressure, gland secretion, etc., can be regulated bidirectionally through "learning" conditioned reflexes. Later, Birk proposed biofeedback therapy and the concept of "behavioral medicine" in 1973. Currently, biological Feedback has been applied in the treatment of many physical and mental disorders. Myoelectric biofeedback is to use electronic engineering technology to feed back some neuromuscular activities that cannot or are not easily perceived by the human body to the patient by means of visual or auditory feedback, so as to help patients train muscles, improve limb muscle functions, and achieve the purpose of treating related diseases.

Surface electromyographic signal is the bioelectrical signal of the neuromuscular system activity that is guided and recorded from the surface of the skin or cavity through electrodes. It has different degrees of correlation with the activity state and functional state of the muscle, so it can be To a certain extent, it reflects neuromuscular activity, and its time-frequency characteristics and nonlinear dynamic characteristics are sensitively dependent on the activity level and state of the system, so it can be used as an effective method for neuromuscular function evaluation, and the signal can also be fed back in real time Guide patients to perform muscle exercises and help patients actively recover. As a treatment method for muscle rehabilitation, low-frequency pulse electrical stimulation stimulates the damaged neuromuscular system to cause passive rhythmic contraction. On the one hand, it strengthens the muscle proprioception and rebuilds neural pathways. Exercise to preserve muscle function, delay the development of atrophy and degeneration, and help muscle function return to normal. In addition, it can also improve the symptoms of muscle abnormalities and restore normal physiological functions by regulating the coordination of the nervous system.

The neuromuscular rehabilitation treatment equipment on the market applies the principles of myoelectric biofeedback and neuromuscular electrical stimulation. Generally, the computer collects the surface electromyography signal and controls the electric stimulator at the same time; but this kind of treatment equipment is generally large in size , requires a special medical cart to move, and is currently mainly used in large hospitals, which is not convenient for home use, and is not conducive to daily use due to the inconvenience of carrying and moving due to its size.
