Method for relating the centre of pressure locus during dynamic stance to the anatomical structure of the foot.

This study describes a new methodology for relating the centre of pressure locus to the anatomical structure of the foot. This technique involved locating three radio-opaque markers placed over anatomically located marks (the posterior border of the calcaneus and the first and fifth metatarsal heads) and relating these to the coordinates of the corresponding centre of pressure. In this manner, dynamic functional data are related to a standing roentgenogram of the complete foot.
