sEMG Signal Acquisition Strategy towards Hand FES Control

Figure 4

sEMG signal acquisition for tasks (hand open, power grasp, fine pinch, pronation, and supination) with FES stimulation. An isometric contraction was performed by the subject for each part of the trial. The motion was repeated 5 times per part. A session included 5 repetitions of volitional contraction, followed by 5 repetitions of sEMG evoked by FES, and finally, 5 repetitions of volitional contraction plus the evoked sEMG by the FES stimulation.
