Abstract
A rehabilitation system for training hand movement of a user, the system comprising: a platform to be attached to the hand of the user; a plurality of finger assemblies operatively connected to the platform, each finger assembly having: a motor, a proximal follower assembly for a metacarpophalangeal (MCP) joint having a proximal rail guide operatively connected to the motor, and an intermediate follower assembly for a proximal interphalangeal (PIP) joint having an intermediate rail guide operatively connected to the proximal follower assembly; wherein a knuckle joint indicator of the proximal rail guide corresponds to a first virtual center and knuckle joint indicator of the intermediate rail guide corresponds to a second virtual center, the alignment of the knuckle joint indicators to the virtual centers enable motion of the finger to be controlled and maintain rotational axes of the finger about each virtual center when the proximal and intermediate follower assemblies are actuated by the motor.
