Development of Motion Feedback System with Functional Electrical Stimulation Using Electromyogram

Abstract

Current researches are studied a movement support and a rehabilitation of physical function for a physical paretic patient. Resent research focuses on Functional Electrical Stimulation (FES). FES have an effect on a severe physical paralysis caused by a cerebral stroke or a spinal code injury. The purpose of this research is development the system for a rehabilitation of physical functions to use at a hospital. The system use Electromyogram (EMG) of physical therapist as an input signal. EMG is used to decide output level of FES. EMG measure using surface EMG (sEMG). This rehabilitation is to do FES and an exercise therapy at the same time. We consider that this rehabilitation is more effective than existing rehabilitations. The measurement posture is sitting position. The measurement motion is elbow joint flexion motion of changing weight of a wristband. The measured sEMG signals is used to decide output level of FES.
