Force Estimation for Prosthetic Hands Using Surface Electromyography

Abstract

In order to improve amputees quality of life, electromyogram (EMG) prosthetic hands have been developed to compensate for some daily activities.A force estimation method for prosthetic hands using surface electromyotraphy is proposed in the paper to help amputees.One hand of the subject is tied to imitate amputees.The subjects would grip the force sensor with his healthy hand, while doing the same thing with the tied hand.Meanwhile, EMG signals and force are acquired by LABVIEW.Then a muscle-force model based on stepwise regression method is established .The experiments are carried out to evaluate the grasping force on a single degree of freedom prosthetic hand.The experimental results show that the proposed method is effective.
