Abstract
The present invention provides a method and device for evaluating foot posture and its effect of the functional biomechanics of the lower extremities. The device is divided into one half and another half, both of which are identical mirror images and which are connected by a releasable connecting member. Each section includes a split-surface platform mounted on a frame. The split-surface platform has a front and a rear plate. The front and rear plates each have a means for adjusting the horizontal angle of the plate through a range of 25.degree. in either direction and a means for indicating the specific angle. The mechanics of the front and rear plates are not connected to each other, thus allowing independent manipulation of the front and rear portion of the patient's foot. The rear plate may be fitted with variable height booster plates for providing sagittal plane control for limb length discrepancies as well as for accommodating high-arched (equinas) foot types. A non-slip surface may be applied to the upper surface of the front and rear plates, as well as the booster plates, to help prevent the patient's foot from slipping from the plate surfaces.
