Abstract

INTRODUCTION In the recent years, several rehabilitation robots had been built and under clinical trials [1,2,3,4]. A literature revealed that robot-aided rehabilitation for stroke patients could speed up recovery process in acute stage and continuously improve motor functions in chronic stage [5]. However, there is no effective and customized treatment exercise specifically designed for robot-aided rehabilitation. An analysis based on biomechanics and model simulation might be useful for constructing such treatment. This study augmented a biomechanical model of human upper limb, conducted a series of experiments by recruiting a stroke patient and twelve normal subjects, and compared experimental and simulation results between stroke patients and normal subjects when they interacted with the rehabilitation robot system.
