Experience of myoelectric prostheses for unilateral below-elbow amputees in a large region of Great Britain is presented. Of the cases considered, 14 were adults and 29 were 16 years of age or less. The rejection rate was 25% overall but it was lower in adults, at 17%. Comparisons with published data and other aspects of myoelectric prostheses are discussed. Just over half the 37 amputees interviewed were independent in activities of daily living; independence was more common in the adults, at 77%. A very large proportion of myoelectric prosthesis users also used body-powered prostheses, demonstrating a need for both types of prosthesis for optimum rehabilitation. It is recommended that myoelectric prosthetic programmes should be carried out from specialized centres with comprehensive facilities for this expensive rehabilitation aid.
