Abstract

It is evident that inappropriate functional electrical stimulation (FES) intensity is easy to trigger muscle fatigue and discomfortableness. This study proposes a FES tuning solution based on surface electromyography (sEMG), which is to form the relationship from sEMG to FES pulse width through the force. Six healthy subjects were invited to verify the proposed method based on the grip experiment. The feasibility of the estimated FES pulse width was evaluated respect to the correlation index (R) between the voluntary grip force and the FES-induced grip force. The experimental results indicated that the estimated pulse width could well induce the grip force that is similar to the voluntary force (\(R>0.9\)), demonstrating the effectiveness of the proposed method and confirming the potential for improving the experience of FES in clinical settings.
