The determination of foot/ankle roll-over shape: clinical and research applications

Abstract

The roll-over shape of the foot/ankle complex is calculated as the transformation of center of pressure data into a shank-based coordinate system. Some qualitative characteristics of roll-over shapes are orientation, translation, radius of curvature, and length. Roll-over shapes may be useful in the design and alignment of prostheses and orthoses as well as in the development of walking models and theories.
