| Popis: | Manual wheelchair users face a high prevalence of upper extremity pain and injuries associated with poor biomechanics and the relatively low mechanical efficiency of conventional push wheeling. Recently developed geared wheels, which permit the wheelchair user to propel forwards by pulling at the handrims using a 'rowing' motion, have been speculated to improve ergonomics and reduce operational energy costs. This study compared the gross mechanical efficiency (GME) and perceived exertion (RPE) of these geared wheels to standard wheelchair wheels after a motor skill-based training session was conducted to familiarise participants with using both wheels. Fourteen able-bodied males were enrolled in the study. A within-participants, repeated-measures design was used to assess oxygen uptake (VO |
