Influence of seat adjustment on the wrist injury risk for the manual wheelchair propulsion

Many studies have shown that the use of the wheelchair is a helpful displacement aid. Some of them relate to the wheelchair instrumentation (Devillard et al. 1992, Veeger et al. 1998) or its adjustments (Hughes et al. 1992, Masse et al. 1992). Our work focuses on the seat arrangement influence on the propulsion technique. For this, we developed a postural ergonometer based on wheelchair. Many studies have shown that the use of the wheelchair induces different injuries (Boninger et al. 2004). The objective of this study is to quantify the influence of the seat adjustment on the wrist injury risk.
