Upper extremity amputees were tested on a standardized series of tasks using a myoelectric hand, a conventional prosthesis (cable-controlled hook), and their normal hand (unilateral amputees only). They answered also a questionnaire on activities of daily living (ADL) and provided other prosthetic information. Amputees who had been fitted only with a conventional prosthesis, and used their prosthesis regularly, tended to wear the prosthesis more hours per day (14 hours) than amputees fitted with a myoelectric hand (9.6 hours), some of whom continued to use a conventional prosthesis for some jobs. However, the amputees with myoelectric prostheses had a greater functional range of motion (ROM) than those with a conventional prosthesis, and many regular wearers of a myoelectric prosthesis had long since rejected a conventional prosthesis. Amputees took about 2.5 times as long to complete the tasks tested with a conventional prosthesis and about five times as long with a myoelectric prosthesis than with their normal hand. Despite the slower function, more than 60% of below-elbow (B-E) amputees accepted the myoelectric prosthesis in preference to a conventional prosthesis, which they had all been fitted with previously. Others preferred to continue using a conventional prosthesis to which they had become accustomed (13%) or no prosthesis (26%). The combination of function, ROM, and cosmetic appearance of a myoelectric prosthesis is preferred by most B-E amputees, despite its slower performance at the present time.
