Adaptive propulsion strategies protect some manual wheelchair users from injury, pg 385
This study compares the propulsion biomechanics of manual wheelchair users with and without upper-limb impairment. Forty-seven manual wheelchair users propelled an instrumented wheelchair ergometer while a 3-D motion analysis system collected joint kinematic and temporal data, as well as hand rim and joint kinetics. The data suggest manual wheelchair users with upper-limb impairment adopt strategies to remain independent, and some of these strategies may protect them from the development of secondary upper-limb pathologies.
Athletics has no impact on should pain in wheelchair users, pg 395
This study investigates the prevalence and identity of shoulder pathology in athletic and nonathletic manual wheelchair users. Fifty-two manual wheelchair users completed a survey regarding the nature of their injury, sports involvement, history, and presence of current and/or past shoulder pathology. Volunteers currently experiencing shoulder pain underwent a clinical examination of both shoulders. No difference was found in the incidence of shoulder pain, past or present, between athletes and nonathletes. These findings indicate that involvement in athletics does not increase, nor decrease, the risk of shoulder pain in the manual wheelchair population.
Seat position impacts wheelchair use, pg 403
This study examines the effect of seat position on hand rim biomechanics. Information on hand rim forces and motion were collected in a motion analysis laboratory while volunteers propelled a wheelchair over a smooth level floor at a self-selected speed. The axle position was changed to examine the effect seat position has on wheelchair propulsion biomechanics. A seat unit positioned behind the drive wheels improved some wheelchair timing variables. Wheelchair timing measures can be improved by altering wheelchair fit.
