esults discourage the routine use of abdominal drainage and suggest that abdominal drainage should be performed sparingly. Hand-rim wheelchair propulsion is straining and mechanically inefficient, often leading to upper limb complaints.

A novel push-pull central-lever propulsion mechanism is compared to conventional hand-rim wheelchair
