Développement d'outils pour l'analyse et la quantification des interactions utilisateur-fauteuil-environnement lors de déplacements en fauteuil roulant manuel

Abstract : ABSTRACT : Wheelchairs compensate for motor dysfunctions, and transform bipedal locomotion to the seated position. The upper limbs become the locomotive limbs. This antiphysiological means of locomotion leads to various specific pathologies, which are mainly neurological and osteoarticular. The purpose of this thesis is to make a significant contribution in the field of biomechanics of wheelchair propulsion by developing tools. These theoretical and experimental tools are mechanical modelling of forces during wheelchair moving, an outdoor kinematics analyse system and an outdoor instrumented wheelchair, called CERAHFIT. We show that integrating rolling resistance parameter is essential to get realistic modelling. Our kinematics analyse system use standard video acquisition and a numerical manikin matched on user wheelchair's pictures to reconstruct users' movements in three dimensions. This system could be associated with CERAHFIT in order to adding measures of puschrim, footrest, seat and backrest forces and moments. The next step of this study will be acquisitions with disable persons in order to obtain unbiased arguments to assist the choices of wheelchair adjustments and to improve wheelchair conception.
