Abstract
Stroke is a cerebrovascular disease which could lead to physiological impairment, which affects one's ability to do activities of daily living. Several previous studies state that only small number of patients regain useful motoric abilities. This is due the fact of which patients' psychological needs are often neglected in a conventional rehabilitation. Hence, the development of rehabilitation methods which ease patient's psychological burden is necessary. The system used functional electrical stimulation with PID control, combined with repetitive game scenario. Seven normal subjects participated in this study. Average impaired hand movement error was 5.66° from target and range-of motion of 87.86% maximum flexion. Game object control accuracy reached 100%. Moreover, subjects showed improved accuracy by 37.18% at the end of the rehabilitation sessions. Impaired hand trajectory also follows control hand movement, proving the system feasibility for rehabilitation use. Future studies with real hemiplegic patient may provide further validation to the system effectiveness.
