How do arm and hand prosthetic devices work?

ANSWER

The oldest and most commonly used prosthetic arm is operated with the body's own movements and a harness that extends in a figure eight across the back and under the opposite arm. Others use a rechargeable battery to run small motors in the prosthetic hand or hook. The battery improves grip strength.
