What are the components of an upper extremity prosthesis?
As stated in your online reading assignment, “each prosthesis consists of a method of suspension that holds the prosthesis to the body; a socket into which the stump fits; mechanical joints (in above-elbow amputations) designed to approximate, at least in part, hand function; and a source of power; to operate the terminal device (either muscle control or external power sources.)”
