Analyse biomécanique pour la compréhension et l’amélioration du fauteuil roulant dans son application au tennis de haut niveau

Abstract : The development of Paralympics has done a lot for a more positive image of handicap and has opened up new opportunities for the practice of disability sport, known to be highly beneficial for the physical and psychological health of disabled people. Conducted in close partnership with a high level tennis player, this study focuses on the influence of the wheelchair settings on its behavior in order to adapt this behavior to wheelchair tennis playing. The study first highlighted the forces of resistance to straight line or rotating wheelchair movements, thanks to mechanical models validated by experiments. Then, the inertial parameters of the seated player's body segments were assessed by adapting a volumic model to the sitting position, and his propulsion at maximal velocity was studied, in order to understand the effect of the seat fore-and-aft position on this movement. Then, an experimental study proved the major influence of the center of gravity position on free rotation, which was modelized too.In a nutshell, this research work has led to a better understanding of the effects of the wheelchair settings on its behavior, its results have allowed to modify various settings on our partner's wheelchair and can be used as a basis for future wheelchair conception/design. They have also proved useful for conventional wheelchairs and in the meantime, our tennis player partner has become wheelchair tennis world champion…
