Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the project is to explore the effect of differences in seat height and seat angle on bilateral foot propulsion using a manual wheelchair. The objectives of the study are to determine whether differences in seat height and seat angle impact: a) propulsion speed; b) knee range of motion used during propulsion; c) effectiveness of foot propulsion gait; and d) perceived difficulty with foot propulsion.

A repeated measures designs allows comparison between 5 different seat height conditions and 4 different seat angle conditions to determine whether there are significant differences in outcome, and if so, which conditions provide better outcomes. Participants will propel a customized MWC through a standardized course using each seat configuration; the sequence will be randomized to reduce any learning effects.
