Abstract: A method for determining an intervention to improve use of upper limb prosthesis which includes instructing a person having an upper limb prosthesis to perform a plurality of tasks, including but not limited to, using the prosthesis in multiple planes, using the prosthesis with a plurality of grasp patterns, using the prosthesis at various distances from the body, using the prosthesis in unilateral and bilateral tasks, and using the prosthesis while the person is arranged in various positions. The method further includes, for each of the plurality of tasks, determining a category score for categories comprising control skills, component feature utilization, compensatory movement, and task completion, and obtaining a cumulative category score for each of the categories based on the category score for each of the plurality of tasks. The method further includes determining an intervention for improving use of the upper limb prosthesis based on at least the cumulative category score for each of the categories.

Abstract: A socket is described for use with a partial prosthesis of the hand. The socket includes a base layer molded to encapsulate and conform to the contours of a natural hand. The base layer has a dorsal portion and a palmar portion. The palmar portion has a distal edge positioned, in use, proximal to the transverse metacarpal arch of a natural hand, and the dorsal portion having a distal edge positioned, in use, along a transverse span along a mid-portion of the dorsum of the natural hand in an area proximal to the area of the second through fifth metacarpals of a natural hand. The palmar portion of the base layer defines a first open area around the hypo-thenar eminence and a second open area surrounding on the palmar portion the thenar eminence and extending to the radial side of the second metacarpal on the dorsal portion.
