The aim of this paper is to present a new method for kinematic analysis of human movements, especiallywalking. This study uses video imaging of ten healthy men walking and kinematic analysis of their movementsusing relative coordinates attached to the body. Joint range of motion is reported based on this pattern. Thismethod directly measures and provides designers with the quantities needed for local biomechanical assessmentsof joints and the design of mobile equipment for the lower extremities.
