Abstract

Transformation of the medial arch angle of human foot was observed at sagittal plane during gait cycle by two methods: X ray television and Computer Aided Video Motion Analysis (VICON). Although the X-ray television has access to measurement of angles between templates, the X ray television has problems such as exposure to radiation, human error in acquiring digital data out of the templates, and low sampling late of Digital Radiograph- Fluroscopy. The VICON is a method to measure 3D coordinates of markers attached at the surface of the foot by 3D video tracking system, then estimate medial arch angle of the templates from the 3D markers. Transformation of the medial arch angle at stance phase were measure by the X ray television and the VICON, and results of the two methods were compared. The transformation pattern estimated by the VICON was approximate to the transformation measured by the X ray. Use of the VICON for the estimation of the medial arch angle of human foot was confirmed.
