SME MS94-230

ALTHOUGH SEVERAL ARM PROSTHESIS MODELS ARE AVAILABLE, THE 1940'S DESIGNED BODY-POWERED TYPE REMAINS THE CHOICE OF AN OVERWHELMING MAJORITY OF AMPUTEES. A RECENT SET OF EXPERIMENTS DESIGNED TO COMPARE UNCONSTRAINED MOTION OF THE UNIMPAIRED ARM AND BODY-POWERED PROSTHESIS CLEARLY SHOWS THE DISCRETE ACTION PHENOMENON NOTED BY SEVERAL OTHER RESEARCHERS IN THE MOTOR CONTROL FIELD: LONG, SMOOTH HUMAN MOVEMENTS APPEAR TO BE COMPOSED OF A SERIES OF SUCCESSIVE SHORT MOVEMENTS. PERFORMANCE BASED ON DISCRETE ACTIONS YIELD INSIGHT INTO ACCURACY AND SPEED CONSTRAINTS ON THE PROSTHESIS AND JUSTIFY FUTURE STUDY OF THIS FEATURE OF MOVEMENT.
