Application of the Capability Model to assess crossfall gradient requirements for attendants pushing wheelchairs.
(Proceedings) 12th International Conference on Transport for Elderly and Disabled People.
The current study set out to investigate the effect of crossfall gradient on attendant wheelchair propulsion by measuring the capabilities required of the attendant to keep the wheelchair travelling in a straight line along three footways with different crossfall gradients (0%, 2.5% and 4%). When travelling on a flat footway, it was found only one capability was required: the ability to produce sufficient force to move the wheelchair. However, when there was a crossfall this capability increased and a second capability was also required: the ability to provide different forces to the right and left handles. The results of this study indicate that the necessity to apply differing forces to the right and left handle while maintaining enough overall force to generate a reasonably straight line in the forward direction may well prove the limiting factor for people’s ability to push a wheelchair along steeper crossfall gradients.
