A Novel Push-pull Central-lever Mechanism Reduces Peak Forces and Energy-cost Compared to Hand-rim Wheelchair Propulsion During a Controlled Lab-based Experiment
Abstract:Background: Hand-rim wheelchair propulsion is straining and mechanically inefficient, often leading to upper limb complaints. Previous push-pull lever propulsion mechanisms have shown to perform better or equal in efficiency and physiological strain. Propulsion biomechanics have not been evaluated thus far. A novel push-pull central-lever propulsion mechanism is compared to conventional hand-rim wheelchair propulsion, using both physiological and biomechanical outcomes under low-intensity steady-state conditio… Show more
