Manual wheelchair propulsion

Consumers, experts, industry contacts and researchers interviewed, identified manual wheelchair propulsion as an area in need of technological advancement. This technology area includes methods of wheelchair propulsion other than manual wheel turning, as well as wheelchair component design changes to facilitate efficient propulsion. There are over 1.4 million wheelchair users and about 75% of them use manual wheelchairs. There has been little change in the design of the manual wheelchairs over the last decade. Manual wheelchairs are complex systems and wheelchair design can limit propulsion, independence and accessibility. The investigation of manual wheelchair propulsion has become increasingly important because the population of individuals using wheelchairs is growing and requires efficient mobility to maintain a quality of life equivalent to the general population. Several attempts have been made at improving manual wheelchair propulsion, such as changes in the wheels and tires, adding gears and designing alternative propulsion systems. Still, experts and consumers generally agree that innovation in propulsion is still needed.
