Rehabilitation system for upper limb of hemiplegic patients and method thereof

The present invention relates to a system for rehabilitating an upper limb of a hemiplegic patient and a method therefor. The system comprises: an operating tool of a small-sized structure; a sensor module sensing a motion of the operating tool and transmits information about the motion; and an auxiliary unit receiving the information about the motion of the operating tool from the sensor module. The auxiliary unit has a game content program which maps the motion of the operating tool on a screen to execute a rehabilitation exercise game. The present invention allows a hemiplegic patient, who cannot move his or her arm freely, such as, a stroke patient or a patient with a prosthetic arm, to perform rehabilitation training in connection with the game, thereby keeping the user amused and interested, so that the user can actively participate in the rehabilitation training.
