Hand rehabilitation device

Hand Rehabilitation Training Device

This technology is a rehabilitation device that guides wrist and hand movements by combining multi-axis rotating joints (first and second axes) with a grip resistance component.

There is a lack of systematic grip and wrist rehabilitation training for patients with physical impairments such as hand paralysis or finger curling to aid in muscle and joint recovery.

This technology features a base frame, a wrist training unit, and a grip training resistance component that includes a spring to adjust the load according to the user's training status and measure joint angles. It can be applied to rehabilitation training, gait assistance, and medical/welfare services. By providing a comprehensive system that trains hand and wrist movements and controls load resistance based on the user's clamping force, it enhances the effectiveness of hand rehabilitation training.

Key Features:

• A first grip member disposed between the other sides of a pair of support members, which induces a hand-clenching exercise based on a first load training value while gripped by the user.
• A grip training unit connected to the base frame to rotate about a second axis perpendicular to the first axis.
• A grip training resistance unit provided with a first spring disposed between a fixed part and a moving part to provide the first load training value.
• The grip training unit includes a pair of support members, one side of which is rotatably connected to the base frame.
