A kinematic characterization of human walking by using CaTraSys

Abstract

This paper presents an experimental characterization of the biomechanics of human gait by means of Cassino Tracking System (CaTraSys). CaTraSys is a passive cablebased parallel manipulator that is used to determine pose and exerted force of mechanical systems along large trajectories. It is a low-cost easy-operable system that has been utilized in the present work for a clinical application as an assessing device for diagnosis and rehabilitation procedures. A methodology for experimental tests and data analysis is outlined, which includes mean extrapolation of acquired trajectory data. Basic characteristics of two-dimensional (2D) and three-dimensional (3D) resulting gait patterns are discussed. Using spatiotemporal parameters, different test conditions and anthropometric characteristics are evaluated in order to assess their influence on the human walking from the kinematic point of view.
