Spatiotemporal analysis of EMG signals for muscle rehabilitation monitoring system

Abstract

This study proposes spatiotemporal EMG signal analysis for muscle rehabilitation monitoring system. Through this monitoring system, users - both patient and therapist - can check one's status: muscle intensity, muscle fatigue, exercise posture, speed and number of movement. We performed three remedial exercises - SLR, SLR(P), and LE - to analyze the EMG signal. In addition, exercises with inappropriate postures and various joint angles also carried out. As a result, clearly different EMG features were extracted for every condition.
