Objective: Upper-limb paresis is a major source of disability in stroke survivors, and robotic device-aided exercise therapy is a promising approach to enhance motor abilities. Few robotic devices have been available to provide therapy to the fingers and hand. This study was designed to test a new robotic device for hand rehabilitation in stroke survivors.
Design: This is an open-label pilot study of 12 individuals with chronic moderate hemiparesis after stroke. Participants underwent a 6-wk training program using a hand robotic device. Participants received a total of 18 hrs of robotic therapy.
Results: Improvements were found in multiple measures of motor performance, including the Upper Extremity Fugl-Meyer test, the Motor Activity Log, the Manual Ability Measure-36, and the Jebsen Hand Function Test. All subjects tolerated the treatment well and no complications were observed.
Conclusions: Robotic therapy for hand paresis after stroke is safe and feasible, and further studies of efficacy are justified by these preliminary results.
