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.
Interventions
OTHERSeat height
Seat height of a manual wheelchair will be changed according the different arms specified. The participant will complete a course in the manual wheelchair with each arm.
OTHERSeat inclination
Seat inclination of a manual wheelchair will be changed according the different arms specified. The participant will complete a course in the manual wheelchair with each arm.

Inclusion criteria
* student in College of Rehabilitation Sciences enrolled in Master of Occupational Therapy, Master of Physical Therapy, or Bachelor of Respiratory Therapy program at the University of Manitoba. * Able-bodied individuals
Exclusion criteria
* Students whose hip width exceeds 21 inches or lower leg length is shorter than 16 inches will be excluded as the test manual wheelchair will not accommodate these dimensions.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| 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). |
