Effect of Seat Height and Angle on Wheelchair Foot Propulsion

- Registration Number
- NCT06035484
- Lead Sponsor
- University of Manitoba
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Effectiveness of foot propulsion gait ~30-60 seconds Evaluated using the Wheelchair Propulsion Test developed by Askari et al. (2013). Simple, valid and reliable measure of propulsion for either upper or lower extremity propulsion techniques.
Perceived difficulty with foot propulsion ~30-60 seconds Participant will provide subjective evaluations of how difficult they found foot propulsion after each trial, using Perceived Difficulty Questionnaire (Heinrichs et al., 2021).
Propulsion speed ~30-60 seconds Speed will be determined via video recording. Two outcomes will be determined initial 10m and total test course
Knee range of motion ~30-60 seconds Xsens sensors and mobile app will be used to determine the positions of the thigh and lower leg and knee joint angle will be obtained from the difference between these positions.
