Conception et évaluation d'un prototype de fauteuil roulant avec une technique non-conventionnelle de propulsion manuelle / Design and testing of a wheelchair prototype with non-conventional manual propulsion technique

Rifaii Sarraj, Ahmad 17 December 2009 (has links)
Le but de ce travail est de prouver la supériorité d’une technique alternative de propulsion manuelle non-conventionnelle basée sur le système à leviers. La faisabilité d’un prototype intégrant la technique non-conventionnelle ainsi que les avantages et les inconvénients sont également recherchés. Les évaluations objectives et subjectives en relation avec l’interface sujetprototype ainsi que les habiletés sur terrain et les paramètres physiologiques ont fait l’objet d’études expérimentales. Le prototype conçu pourrait constituer une tentative dans le domaine de l’handisport permettant aux sportifs handicapés de recourir à une stratégie de propulsion manuelle non-conventionnelle évitant les complications induites par la technique conventionnelle / Wheelchair propulsion has been reported to be responsible for musculoskeletal pain in the upper extremities. Epidemiological studies have shown a high prevalence of shoulder complaints in paraplegic and quadriplegic spinal cord injured (SCI) people. It has been argued that the high incidence of shoulder complaints in SCI was the result of the weightbearing or propulsion function of the upper extremity in those subjects. This work aimed at proposing an alternative wheelchair propulsion technique based on the levers’ system. The interface prototype-users, the wheelchair skills evaluation, the oxygen uptake and the cardiac frequency are investigated by an objective and subjective studies. Our prototype is designed to be an attempt in the field of disabled athletes having some advantages of a non-conventional manual wheelchair propulsion technique, avoiding complications induced by the conventional one
