The effect of parameters of vibration stimulation on muscles during knee joint extension motion change

Abstract

Vibration stimulation on an antagonist muscle changes human motion from his/her intended motion. In previous studies, it has been already known that the human motion change can be generated in forearm supination/pronation, elbow joint flexion/extension, and knee joint extension motion. The purpose of this study is to investigate the effect of frequency change to the amount of knee joint extension motion change. The experimental results suggest that the frequency change from 20 to 100 (Hz) affects the amount of knee joint extension motion change.
