What this research studies
You would try a manual wheelchair that moves the hand rims forward using a chain drive so pushes happen along a longer, more comfortable arc while keeping the big wheels behind for stability. The wheelchair has changeable gearing so you can use a lower gear for starting or rolling over carpet and a higher gear for steady pushes on flat ground. In a crossover test, 18 Veterans with spinal cord injury will try three gear settings (low, normal, high) while researchers measure the work at the pushrims and the calories you burn. The goal is to compare how different gear ratios affect how much effort it takes to move and how far you can go per unit of energy.
Who could benefit from this research
Good fit: Veterans with spinal cord injury or disorder who use and can self-propel a manual wheelchair are the ideal candidates.
Not a fit: People who rely on power/electric wheelchairs, cannot self-propel, or whose shoulder/arm function is too limited to use a manual chair likely would not benefit from this device.
Why it matters
Potential benefit: If successful, this could reduce the physical effort needed to push a manual wheelchair and improve daily mobility and independence.
How similar studies have performed: Previous ergonomic handrim designs have shown promise for reducing propulsion effort, but using adjustable multi-speed gearing in a manual wheelchair is a newer idea that has not been fully studied in people.
