The platform comprises a plurality of beams each of which is supported at each end by means for detecting the load imposed on each beam. The video outputs of the two cameras and the load on each beam are displayed on a monitor screen. The apparatus also includes circuitry for determining from the loads on the ends of the beam where the center of pressure is on each beam. These centers of pressure are displayed superimposed on the image of the plantar surface. | |
