Apparatus for analyzing the forces acting on a human foot
First Claim
1. An apparatus for analyzing the forces acting on a foot comprising:
- a platform composed of a plurality of transparent beams,each end of each beam being associated with means for measuring a load imposed on that end of the beam by a subject walking across said platform;
a first television camera for providing a first video image of the gait of said subject;
a second television camera for providing a second video image of the plantar surface of the foot of said subject as viewed through said platform;
means for converting the output of said measuring means to a visual display signal representative of the force acting on the foot of a subject walking across said platform; and
,means for simultaneously displaying said first and second video images and said force representative visual display signal.

Abstract
Apparatus for analyzing the force acting on the human foot comprises television cameras for photographing the gait of the subject and for photographing the plantar surface of his foot through a transparent platform. 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.
