Influence of Varying Level Terrain on Wheelchair Propulsion Biomechanics

This study investigates how different level ground surfaces affect the way people in wheelchairs propel themselves. It looks at smooth and rough concrete, tile, and carpet. Researchers measured the forces and timing of wheelchair propulsion on these surfaces to understand how the terrain impacts the effort required. The findings can help in designing homes and communities that reduce the strain on wheelchair users' upper bodies, potentially preventing injuries.

• 1
  Propulsion frequency was significantly greater during both concrete conditions than either tile or carpet ground conditions.
• 2
  Forces and moments were greatest during the aggregate concrete ground condition and lowest during propulsion across tile flooring.
• 3
  There were no side-to-side differences for any of the temporal or kinetic variables.
