This project aimed to compare the vibration transmission and required effort to propel different folding manual wheelchairs. The transmitted vibration from the seat to the user exceeds the recommendations from the ISO 2631-1 norm. However, we did not know if an improvement in vibration absorption is or is not correlated to the required energy to propulsion effort.
This project in partnership with Motion Composites aimed to improve the knowledge on these aspects of wheelchair propulsion. Our results suggest that a wheelchair frame made of carbon transmits less vibration to the body than an aluminum wheelchair, and that this better absorption does not lead to a higher propulsion effort.
