Myoelectric prosthetics is an advanced system of upper limb prosthetics that uses electrical signals from the muscles in the residual limb to control movement in the attached artificial limb. The user is trained to use specific muscles so as to activate sensors in the prosthesis which in turn activates motion commands via an electric motor. The technology is fast moving in this area and new developments increasingly mimic the dexterity and versatility of the human hand and arm.
