Evaluation of the Effect of Cycling wheel chair on Driving force and Usability by Changing the Seat Position

Abstract

In this study, we evaluated the usability of a cycling wheelchair by changing the seat position. A cycling wheelchair is one of the system that lower-limb disabled patients are able to move easily. However, when the patient uses the cycling wheelchair in the daily life, it has some structural problems. In order to resolve the problems, we focus on the position of the seat. We evaluate the influence that between user ’s pedaling motion and the position of the seat. For analyzing, two links model is used to estimate hip and knee joint torques. Finally, we conducted the experiment to confirm the effect of the seat position.
