Impact of the subject and wheelchair properties during slope ascent in manual wheelchair: a theoretical study

摘要

This study investigated the influence of the MWC and subject characteristics on the tangential effort applied by the user on the handrim to ensure the MWC propulsion on slope, using this tangential force as an indicator of the propulsion difficulty. This work allowed characterising other effects than the expected wheelchair weight, and could help improving the wheelchair design for enhancing slope ascent capabilities. The mechanical model defined for this study could also be used to help in the definition of future standards for building accessibility.
