The study of Running Specific Prostheses (RSPs) is often limited to the blade. The setup developed and presented here is a simple experiment based on a testing machine and a camera that assesses two indicators relevant to coaches and athletes in the field of athletics: secant stiffness and energy dissipation. The influence of four parameters on global prosthesis behaviour was assessed: the load line adjustment, the prosthesis-ground angle, the sole type and the flooring type. The load line adjustment and the flooring type have little to no influence on their behaviour. The prosthesis-ground angle impacts the stiffness: an increase in angle brings a significant decrease in stiffness. The influence of the type of sole is harder to use for athletics since the practice of sport imposes the use of spikes. The camera images allow assessing the local behaviour of the sole, thus enabling to follow its strain through the compression process. |
