A Virtual Reality based Training and Assessment System for Hand Rehabilitation

Virtual reality is widely applied in rehabilitation robot to help post-stoke patients complete rehabilitation training for the body function recovery. Most of virtual rehabilitation training systems lack scientific assessment standards and doctors don't usually use quantitative examinations but qualitative observation and conversation with patients to evaluate the motor function of limb. Based on this situation, a virtual rehabilitation training and assessment system is designed, which contains two rehabilitation training games and one assessment system. The virtual system can attract patient attention and decrease the boredom of rehabilitation training and assessment. Compared with the existing rehabilitation assessment methods, the proposed virtual assessment system can give the assessment results similar to Fugl-Meyer Assessment, which is more quantitative, interesting and convenient. Five volunteers participate in the study of assessment system and the experimental results confirm the effectiveness of assessment system.
