Abstract: The invention provides an apparatus and method for recording characteristics of a person's foot and for interpreting the results to design a function foot orthosis. As the person undergoes a movement routine, video cameras (24, 26, 28, 30) view the person's foot in real time from below, from the front, from the right side and from the rear to produce simultaneous images which together give a three-dimensional record of the person's foot. During analysis, selected video images from the recordings are calibrated and analyzed geometrically to ascertain the characteristics of the person's foot. A functional orthotic is designed and manufactured by computer-aided apparatus.
