D-2-5 Effect of rear wheel operation for manual wheelchair by helpers on user's riding comfort and helper's physical strain, navigating steps(General Session in English (2))
Proceedings of the Annual Conference of Biomedical Fuzzy Systems Association
Abstraet; steps are one ofthe main,tLictons that have an qt}lect on the physical strain of wheelchair heipers andthe scoflety oj'u4heelchair usens. in this stzicly, we examined the relationship between the movement of the rear veheels ofthe wheelchair during the navigation ofsteps and ive examined the relationship between the movement of the rear wheels of the wheelchair during the navigation of steps, and the pbysical strain ofheipers and user 's riding conzfort. Although the niaximum height
