2 Fig 1 Able-bodied subject in instrumented wheelchair during level wheelchair propulsion. Legend: 1, data logger; 2, instrumented wheel; 3, technical marker; 4, electromyographic electrodes (electromyography not used in our study).

5 Fig 4 Net shoulder moments (mean, SD) during the reaching tasks for able-bodied subjects (AB) and subjects with paraplegia (PP) and tetraplegia (TP) for 3 different mass conditions. Reaching height was 0.5m. *Significantly different (P<.001).
