Balance, Limits of Stability, Posture, Self-Help Devices, Sitting Position, Wheelchairs
Conditions
Brief summary
The study's aim is to assess the sitting and dynamic postural control of stability of wheelchair users who have compromised postural control and risk of ulcers while using individually adjusted multi-cell air cushions with and without individual cell-locking function and variable depths.
Interventions
DEVICEWheelchair air cushion
Reaching tasks during each of the seating conditions decribed in the Arms section.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Reach distance | Day 1 | the linear distance from the start position to the furthest reach point during the trial |
| Accuracy | Day 1 | the ratio of the minimum distance (straight line) from the start position to the total distance traveled until the furthest reach point |
| Time | Day 1 | length of time from the start position to furthest reached point |
| total path length of Center of Pressure | Day 1 | — |
| mean velocity of Center of Pressure | Day 1 | — |
| pressure-distribution between the seating surface and the two foot Force-sensing arrays | Day 1 | — |
