ABSTRACT:
A body-powered prosthetic arm is mountable on a socket attached to the arm stump of a person. The prosthetic arm includes a base for attachment to the socket, a forearm section having a proximal end and a distal end, a terminal device such as a hook, anthropomorphic hand, etc. attached to the distal end of the forearm section for selectively opening or closing, and an elbow joint for joining the proximal end of the forearm section to the base, the elbow joint being pivotable to enable moving the forearm section upwardly or downwardly. Control straps and cables fitted on the person are responsive to body movements of the person for selectively locking the elbow joint to prevent it from pivoting while allowing the terminal device to open or close or locking the terminal device to prevent it from opening or closing while allowing the elbow joint to pivot.
