Consequences of a change in rear-wheel position on seating ergonomics and mobility in spinal cord injured wheelchair users
(English)Manuscript (preprint) (Other academic)
The aim of this study was to analyse the consequences of a change in rear-wheel position on mobility and seating ergonomic aspects. Twelve randomly selected paraplegic wheelchair users were tested iu two different activities, treadmill propulsion and computer work, in two different seating positions. The change in wheel position did affect chair ergonomics with respect to weight distribution and seat-inclination. These changes did have an effect on push frequency and stroke angle during treadmill, propulsion. We found no consistent effect on mechanical efficiency, estimated exertion, breathlessness or seating quality in this group. Nor did we find any consistent significant effect on pelvic position or under-seat pressure. There are effects from wheelchair adaptation, but these seem to be individual. With the knowledge of risk factors related to seating posture in mind, future research concerning effects of wheelchair adaptation has to be performed with considerations for individual changes.
