This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers at the VA have designed a special ergonomic wheelchair with a chain drive system that positions the hand rims in a way that may reduce shoulder strain and improve pushing efficiency. This study will test whether different gear ratios (similar to gears on a bicycle) help wheelchair users move more efficiently on flat surfaces, carpet, and inclines. The goal is to develop a multi-speed wheelchair that adapts to different terrain and situations.
Many manual wheelchair users experience shoulder pain and fatigue from propelling their chairs. While the new ergonomic wheelchair design shows promise, researchers haven't yet tested whether adjustable gears can make pushing even more efficient and easier for different situations—like starting movement, climbing slight inclines, or rolling over carpet.

You will come to the research center and try pushing the ergonomic wheelchair with three different gear settings—one that helps with difficult terrain, one standard setting, and one optimized for flat surfaces. Researchers will measure how much energy you use and how efficiently you move using specialized equipment at the hand rims. In the second part of the study, you'll compare your own standard wheelchair to a new multi-speed ergonomic wheelchair to see which works better for you.
