Research on Microelectronic System of Antagonism Inhibiting Spasticity Based on Electro-Myo-Graphic Bridge

In this paper, based on the principle of stimulating antagonistic muscles, functional electrical stimulation (FES) is used to achieve the purpose of spasticity suppression. The microelectronic system for spasticity suppression was designed and studied, and then used to simulated spasticity of healthy people. First, based on the characteristics of spastic EMG signals, obtained by the EMG signal detection system of the research group, a detection module was designed to detect EMG signals of voluntary movement, simulated EMG signals of spastic patients. Furthermore, an adaptive pattern recognition algorithm for spasticity was designed to identify spasticity signals from the detected EMG signals. Then, on basis of the functional electrical stimulation core circuit of the research group, a microelectronic FES system based on the myoelectric bridge was designed. Finally, the functional verification experiment of the FES system to stimulate antagonist muscle to inhibit spasm was carried out, The results show that the system is effective for stimulating the wrist extensor muscle as an antagonist muscle to inhibit spasm.
