A dynamic system adapted to test a human subject to determine the degree to which his physical stability is impaired without regard to the cause of impairment. The system includes an unsteady platform on which the subject to be tested stands, the platform being supported at a raised position above ground to normally lie in a horizontal plane having an X axis which extends through the center of the platform and a Y axis which is normal to the X axis and extends through the center. The platform is tiltable by the subject standing thereon about the X and Y axes to thereby change the orientation of the platform, the tiltability being is restrained so that the standing subject is not rendered insecure. Electronic sensors are mounted on the platform yield signals which depend on the deviation of the platform from the X and Y axes. When the subject standing on the platform shifts his weight thereon to change the orientation of the platform, the resultant signals are indicative of the degree to which the stability of the subject is impaired.
