During functional wheelchair movement there are several types of
stroke pattern that a manual wheelchair user (MWCU) can utilize in order to propel. Objectives: To examine the biomechanical differences between disabled
(WCU) and able-bodied (NWCU) children whilst taking part in functional activities
at the Cheetahs Wheelchair Sports Club. Study Design:
A multiple measures cohort
study. Methods: Eleven participants were divided into two groups; WCU (n = 7) and
NWCU (n = 4). All subjects were asked to perform three functional tasks;
30-second agility test, 1-minute distance test and a 10-metre sprint test. Upper
body kinematics were recoded using a XSens MVN BIOMECH motion capture suit.
Results: NWCU outperformed the WCU in all of the tasks, however, no significant
differences between the group's results were found. Nevertheless, significant
differences were found in the maximum shoulder flexion angle for both right and
left with NWCU utilizing more flexion and near significant differences in the
NWCU overall shoulder range for right and left. Conclusions: In order to increase
function in young MWCU then more specific-based sessions should be implemented
targeting the exploitation of large shoulder ranges during propulsion,
consequently resulting in more efficient movement. Clinical relevance Employing a
propulsion technique which uses larger ranges of shoulder motion and decreased
pushrim frequency results in an optimal cost-effect balance without predisposing
MWCU to overuse injuries.
