Method ：Multiple angle micro-sensors were used to acquire the angle data of some positions of upper extremities in the virtual rehabilitation to interactively driven a virtual object in the virtual environment. A new concept of compensative motor rate and recognition algorithm of compensative motor were proposed to judge and quantify the compensative motor in the basic motion training. With the help of a newly-constructive virtual rehabilitation plat- form, three subjects with normal upper extremity function completed a simulation training of wrist extension re- spectivelywithdifferent motion modesin ordertoverify therecognitionalgorithm ofcompensativemotor.
