A kinematic characterization of human walking by using CaTraSys

• This work presents a characterization of human gait using CaTraSys.
• A procedure is outlined for experimental tests and data analysis.
• Acquired data and spatiotemporal parameters are elaborated for example evaluations.
• Gait patterns are discussed from the kinematic point of view.
• Influence of test conditions and anthropometric characteristics is discussed.

This paper presents an experimental characterization of the biomechanics of human gait by means of Cassino Tracking System (CaTraSys). CaTraSys is a passive cable-based 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 used in this work for a clinical application as an assessing device for diagnosis and rehabilitation procedures. A procedure is outlined for experimental tests and analysis of acquired trajectory data. Basic characteristics are discussed by referring to two-dimensional and three-dimensional resulting gait patterns. Using spatiotemporal parameters, different test conditions and anthropometric characteristics are evaluated in order to assess their influence on human walking from the kinematic point of view.
