During the last four years, the Texas Institute for Rehabilitation and Research has had gratifying results in the restoration of function in the upper extremities of most of 32 patients, by various combinations of powered assistance. The selection of candidates for these devices is governed by evaluation of the patients' psychologic and physiologic conditions. From roentgenographic analysis of the musculoskeletal structure of the normal hand holding common objects, a pattern for the examination of integrated motion was perceived and a plastic hand orthosis was devised that can be readily reshaped by heat for individual adaptation. This versatile orthosis gives the required support and yet allows passive digital mobility. The patients are thoroughly trained in the use of equipment by a qualified occupational therapist. The patient and his family are given thorough instructions in operating and maintenance procedures. Periodic medical and orthotic reevaluations of these patients provide impetus to efforts to increase the versatility of the motions provided by externally powered assistance. Research at present is directed toward simplifying and making more efficient mechanical adaptations and developing self-contained power units for ambulatory patients.
