1. A wearable power assistive device for hand rehabilitation comprising:
(a) a palm brace having an external platform and an internal platform connected to and spaced inwardly from the external platform, the external platform extending in a longitudinal direction between proximal and distal ends thereof; (b) a plurality of finger assemblies adjustably mounted on and extending outwardly from the distal end of the external platform generally in a longitudinal direction, each finger assembly comprising a proximal follower assembly for a metacarpophalangeal joint; and (c) a plurality of motors for actuating the plurality of finger assemblies respectively, each motor having a proximal end connected to the proximal end of the external platform through an individual rear support, and a distal end of each motor coupled to its corresponding proximal follower assembly by a ball joint;
wherein the external platform has an inturned thumb platform, and one of the finger assemblies for the thumb is adjustably connected to the inturned thumb platform;the device further comprises an engagement member detachably mounted on an inner surface of the inturned thumb platform, the engagement member having two opposite sides, each having a plurality of longitudinally spaced projections selectively engageable with the plurality of longitudinally spaced recesses formed on the proximal end portion of the finger assembly for the thumb, wherein the inturned thumb platform is formed with a plurality of laterally spaced and longitudinally elongated openings, and wherein at least one screw is adapted to pass through a selected one of the laterally spaced and longitudinally elongated openings and is releasably driven into the at least one threaded opening of the finger assembly for the thumb, thereby allowing the finger assembly for the thumb to be adjustable in the longitudinal direction to match different thumb lengths and adjustable to different lateral positions to match different thumb positions. |
