A technique to train finger coordination and independence after stroke

Abstract

PURPOSE: Finger coordination and independence are often impaired in stroke survivors, preventing them from performing activities of daily living. We have developed a technique using a robotic interface, the HandCARE, to train these functions. METHOD: The Hand Cable-Actuated REhabilitation (CARE) system can assist the subject in opening and closing movements of the hand, and can be adapted to accommodate various hand sizes and finger shapes. RESULTS: Two game-like exercises have been developed, which use a motivating approach to promote recovery of finger coordination and independence. Mathematical measures have been implemented to evaluate these functions. This technique is validated with two post-stroke subjects who practiced for 20 minutes twice a week during eight weeks. CONCLUSIONS: The results show significant improvements in finger coordination, force modulation as well as finger independence.
