Influence of trunk flexion on biomechanics of wheelchair propulsion

J REHABIL RES DEV , 2000, vol. 37, n° 3, p. 283-295 Doc n°: 98010 Localisation : Documentation IRR Descripteurs : DF3 - ANALYSE DU MOUVEMENT, KF6 - FAUTEUIL ROULANT Propulsion styles that are characterized by high stresses may influence the susceptibility of manual wheelchair users (MWCU) to upper limb injury. An experimental, cross-sectional study was designed to compare physiological and bio-mechanical characteristics of wheelchair propulsion in two groups of MWCU - a trunk flexion propulsion style group (FG) and a non-trunk flexion propulsion style group (NFG) - across fresh and fatigued states. Data on joint kinetics and kinematics, handrim kinetics, propulsion temporal characteristics, and electromyography were collected at the fresh and fatigued states, and oxygen uptake was collected continuously, to characterize wheelchair propulsion performance of 19 MWCU during a sub-maximal exercise test to exhaustion. The FG was characterized by a more flexed trunk position accompanied by greater shoulder flexion and elbow extension (p<0.05), which was accentuated with fatigue when compared to the NFG.
