Mechanisms of Sporadic Control Failure Related to the Skin-Electrode Interface in Myoelectric Hand Prostheses

Introduction This study is concerned with the control of hand prostheses based on electromyograms. As the prosthesis is moved in space, the socket and electrodes can shift on the residual limb, causing changes in the observed electromyograms. These changes can be misinterpreted by the electronic controller and cause the hand to move unintentionally or fail to execute solicited movements. The goal of this study was to explore the mechanisms...
