Wearable muscular movement state recognition and electrical muscular stimulation movement assistant system

Abstract

The invention relates to a wearable muscular movement state recognition and electrical muscular stimulation movement assistant system. The system comprises a binding belt which is provided with corresponding electromyographic signal collection points and muscular stimulation points, and a signal analysis control center is arranged on the back of the binding belt; the electromyographic signal collection points are used for completing collection of electromyographic signals, and transmitting the collected electromyographic signals to the signal analysis control center; the signal analysis control center is used for analyzing the collected multichannel electromyographic signals, judging the muscular movement type and generating stimulation voltage data corresponding to the type according to the muscular movement type. According to the stimulation voltage data, the muscular stimulation points generates stimulation signals to stimulate muscular contraction. By means of the system, corresponding stimulation current can be generated according to the movement condition of a specific muscle group, muscular contraction is generated, and therefore the movement is assisted.

Description

technical field [0001] The invention relates to the technical field of myoelectric signal perception and motion assistance, in particular to a wearable muscle motion state recognition and muscle electrical stimulation motion assistance system. Background technique [0002] In recent years, people have paid attention to the use of functional electrical stimulation (FES) for post-stroke treatment to achieve motor function rehabilitation. Many experiments on stroke patients with functional electrical stimulation have shown that FES can promote neuroplasticity. It has a positive effect on the recovery of motor function of patients. A normal human body transmits electrical signals from the motor cortex nerves to the motor nerves of the spinal cord, and the nerve signals from the motor nerves are transmitted to the neuromuscular junction to activate the muscles to generate force, thereby realizing the movement of the limbs. For stroke patients, due to central nervous system damag...
