The purpose of this work is to evaluate the mechanical energy exchange during the gait cycle of a subject equipped with energy storage devices (jumping stilts). For comparison, the same evaluation was carried out in a gait cycle with no jumping stilts (natural gait). First, a video of the motion was recorded, then the video frames were post-processed to obtain the sagittal plane trajectories of eleven markers (geometric points) placed onto the subject and finally a numerical code was developed to build up a multi-bodies model able to compute the mechanical energy during the gait. Further, the results from the multi-bodies model were compared with those from a simplified model based on the motion of the centre of mass of the subject.

Abstract

The purpose of this work is to evaluate the mechanical energy exchange during the gait cycle of a subject equipped with energy storage devices (jumping stilts). For comparison, the same evaluation was carried out in a gait cycle with no jumping stilts (natural gait). First, a video of the motion was recorded, then the video frames were post-processed to obtain the sagittal plane trajectories of eleven markers (geometric points) placed onto the subject and finally a numerical code was developed to build up a multi-bodies model able to compute the mechanical energy during the gait. Further, the results from the multi-bodies model were compared with those from a simplified model based on the motion of the centre of mass of the subject.
