A method and apparatus for use in analyzing the gait of a subject has an elongated transparent platform over which the subject may stride and a moveable camera disposed below the platform for viewing the plantar aspects of the subject's foot while the subject strides. The camera is mounted on a trolley driven by a cable and pulley system connected to a belt worn by the subject so that the camera is moved in synchronism with the strides of the subject. High intensity lighting including a fluorescent lamp is placed closely adjacent to one edge of the platform while the remaining edges are covered with highly reflective material to minimize loss of light. The surface of the platform is heated by electrical heating elements so as to preclude the formation of condensation as the subject strides over the platform.
A method of analyzing the gait of a human subject comprising,
Apparatus for use in analyzing the natural gait of a subject while striding comprising, an elongated transparent platform having a surface on which the subject may make a number of strides, a camera, means for mounting said camera for viewing from beneath said platform the plantar aspects of at least one foot of said subject, and drive means for moving said camera in response to the strides of the subject so that the plantar aspects of said foot may be monitored throughout at least one full gait cycle while the subject is moving.
