Method：Take advantage of angle sensors acquiring the angle data of some positions of upper extremity in the vir- tual rehabilitation to interactively driven a virtual object in the virtual environment. Propose a new concept equiva- lence rate and recognition algorithm of motor equivalence to judge and quantify the motor equivalence in the ba- sic motion training. With the help of a newly-constructive virtual rehabilitation platform, three trainers with nor- mal upper extremity function complete a simulation training of wrist extension respectively with different motion modes in order to verify the recognition algorithm of motor equivalence. Result：In the comparative trial，the results of the equivalence rate under correct motion mode and modes of mo- tor equivalence measured by the virtual training platform are in accordance with the practical situation. Conclusion：The recognition algorithm of motor equivalence mentioned in the rehabilitation training method is ef- fective to recognize the motor equivalence occurred in basic motion training of upper extremity and the introduc- tion of the concept equivalence enriches
