A motor function evaluation system for quantitatively, objectively, noninvasively, and simply evaluating the motor function of a subject. The system comprises (a) means for displaying image information including a target image and a cursor image for tracking the target image, (b) means used when the subject moves the cursor image, (c) means for detecting the state of tracking the target image by the cursor image, (d) means for detecting the active state of muscles of the subject using the means (b), (e) means for analyzing the tracking state detected by the means (c) and the muscle active state detected by the means (d), and (f) means for evaluating the motor function of the subject by using the analysis result obtained by the means (e) as an index.
