Abstract

A technique to analyze the functional instability of an ankle is proposed. The technique is based on measurements using two digital still cameras. We carried out several experiments using this technique. Subjects are requested to stand on an experimental table whose angle of inclination is adjusted. By comparing the postures of both feet, we could tell that the subjects had experienced an ankle sprain and had functional instabilities in their ankles.
