Electrotactile EMG feedback improves the control of prosthesis grasping force

A drawback of active prostheses is that they detach the subject from the produced forces, thereby preventing direct mechanical feedback. This can be compensated by providing somatosensory feedback to the user through mechanical or electrical stimulation, which in turn may improve the utility, sense of embodiment, and thereby increase the acceptance rate.In this study, we compared a novel approach to closing the loop, namely EMG feedback (emgFB),...
