Myoelectric Upper Extremity Prosthesis

The Myoelectric uses signals from muscles of the residual limb to control the opening and closing of the terminal device (hook or hand) or elbow depending on the level of amputation. Electrodes are incorporated into the prosthetic socket and by contracting the muscles of the residual limb, electrical signals are sent to the motors which open and close the terminal device (hook or hand) or lift and lower the forearm at the elbow.
