Abstract

Our novel prosthetic hand is controlled by extrinsic flexor muscles and tendons of the metacarpal-phalangeal joints. The hand uses tendon-activated pneumatic (TAP) control and has provided most subjects, including amputees and those with congenital limb absence, control of multiple fingers of the hand. The TAP hand restores a degree of natural control over force, duration, and coordination of multiple finger movements. An operable hand will be demonstrated.
