Rehand Lightweight robotic solution for REHABILITATION OF FINGER/THUMB MANIPULATION and FUNCTIONAL GRASP


Rehand ReHand:

What is it? The ReHand is a patent-protected, lightweight robotic solution for rehabilitation of finger/thumb manipulation and functional grasp. The modular hand rehabilitation system is designed to target a large range of hand impairments (from mild to severe) following stroke. The system is intended to be used as a standalone device or in conjunction with arm rehabilitation systems, such as TECNALIA’s ArmAssist system. In both scenarios, the device is compatible with virtual training software interfaces such as TECNALIA’s ReHub. The ReHand module provides force assistance to the thumb and fingers in flexion and extension and allows sufficient thumb mobility to enable training of essential styles of grasp as well as independent control of at least 3 digits: index, thumb and coupled middle, ring and little fingers.

Features Portable and modular.

Lightweight robotic solution for rehabilitation of finger/thumb manipulation and functional grasp

Why ReHand Impaired subjects have difficulty in finger extension. Healthy subjects most often use fingers in extension during grasp tasks - where moderate to severe patients can’t reach. Design is focused on extension exercise, but control allows both actuation directions (flexion + extension). Real sensorial (tactile) feedback is preferred over artificial (e.g. vibrotactile stimulation). ReHand fingertips are unobstructed. Main focus for clinicians is on EARLY rehabilitation of subacute patients; basic movements are primary focus. Independent movement for each finger highly desirable (not necessarily simultaneous). Thumb: one active flexion/extension DoF; manually adjustable adduction/abduction. Sensors: force & position, for clinical assessment. Compliant structure. Clinically validated (18 stroke patients).

Lightweight (1kg) and wearable. Independent finger actuation.
