Wearable Power Assistive Device for Helping a User to Move Their Hand
A rehabilitation system (10) for training hand movement of a user, the system comprising: a platform (24) to be attached to the hand of the user; a plurality of finger assemblies (71) operatively connected to the platform (24), each finger assembly (71) having: a motor (12), a proximal follower assembly (13) for a metacarpophalangeal (MCP) joint having a proximal rail guide (14) operatively connected to the motor (12), and an intermediate follower assembly (16) for a proximal interphalangeal (PIP) joint having an intermediate rail guide (17) operatively connected to the proximal follower assembly (13); ; wherein a knuckle joint indicator (22) of the proximal rail guide (14) corresponds to a first virtual center (30) and knuckle joint indicator (25) of the intermediate rail guide (17) corresponds to a second virtual center (31), the alignment of the knuckle joint indicators (22, 25) to the virtual centers (30, 31) enable motion of the finger to be controlled and maintain rotational axes of the finger about each virtual center (30, 31) when the proximal and intermediate follower assemblies (13, 16) are actuated by the motor (12).
