Influence of floor surface on the energy cost of wheelchair propulsion

Abstract

Carpeting of the type commonly used in hospitals imposed a burden upon normal and patient wheelchair users propelling a wheelchair as reflected in increased energy cost per unit of distance traveled. Wheelchair propulsion also tended to produce high heart rates compared to values reported for normal walking. Pneumatic tires offered no advantage over hard rubber tires on the type of carpet used in this study. Wheelchair propulsion required more energy expenditure per minute than values reported for normal ambulation at the same velocity.
