Abstract

Introduction Kinematic analysis of motion often requires the evaluation of quantities not always directly measurable, like velocity and acceleration in order to be complete. (Hatze 1984). Acceleration could be measured by means of accelerometers fixed to the landmarks to be analyzed, but due to the disturbance ofthe subject it is better to compute them from the landmarks' trajectories evaluated by means ofa movement analyser using a passive marker, like the ELITE system (Ferrigno and Pedotti 1985).
