With an estimated 1% of the total population wheelchair dependent and despite the low mechanical efficiency associated with hand-rim wheelchair propulsion, hand rim propulsion continues to be the most common mode of propulsion in daily life and wheelchair sports.

Numerous factors make up the wheelchair-user combination and are suggested to contribute to wheelchair propulsion performance. Factors that can be easily manipulated by individuals are important starting points into the understanding of hand-rim wheelchair propulsion and the optimisation thereof, in particular the physiological aspects and mechanical efficiency.

The present thesis investigates the efficiency of synchronous and asynchronous hand-rim wheelchair propulsion strategies. The results provide a platform for the both theoretical as well as practical significance in the context of propulsion. Generating information on optimum conditions for cyclic arm work in rehabilitation and wheelchair sports is important for wheelchair performance and efficiency of functioning.
