Abstract: The use of theoretical models is an alternative for studying the configuration of manual wheelchairs. Richter and Morrow proposed one of the theoretical models used to study propulsion in manual wheelchairs. However this analytical model is limited to use in the sagittal plane. This article presents a quasi-static 3D model that could examine wheelchair propulsion and provide performance analysis during 3D motion. The 3D model takes into account parameters such as axial forces on the hand, the lateral distance between the shoulder joint and the centre of the axis of the propulsion wheel and the angles of inclination of the propulsion wheel (camber angle). The results obtained using our 3D model of wheelchair propulsion show the influences of the lateral distance between the shoulder joint and the axis of the propulsion wheel as well as the effects of the camber angle in the shoulder and elbow joints.
