Abstract
A method and apparatus for providing a topographical map of the bottom of a patient's rear foot with the foot in a semi-weight bearing condition and in the neutral position adjusted for the effects of tibial torsion. A foot scanner with a pivoted air cushion is adjusted to a first position whereupon the foot is captured. Then the air cushion is oscillated relative to the first position until the talus and navicular exhibit congruency to establish a measurement position. A three-dimensional scanner measures the distances corresponding to the spacing between a reference plane and the bottom of at least the rear foot and midfoot. A manufacturing facility converts these measurements into information by which computer numerical controlled equipment machines an orthotic insert for the patient's footwear.
