Abstract

An electrically-operated hand, controlled by myopotentials, has been fitted with strain gauges in the index finger which measure the gripping force between thumb and index finger. These strain gauges cause an electrical stimulus to be applied to the skin directly above the median nerve. This stimulus consists of a series of pulses with the pulse repetition rate increasing as the pinch force increases. Patients fitted with prostheses incorporating this feedback report an improved level of confidence when using the prosthesis.
