This study describes a new custom measurement system designed to investigate the
biomechanics of sitting-pivot wheelchair transfers and assesses the reliability
of selected biomechanical variables. Variables assessed include horizontal and
vertical reaction forces underneath both hands and three-dimensional trunk,
shoulder, and elbow range of motion. We examined the reliability of these
measures between 5 consecutive transfer trials for 5 subjects with spinal cord
injury and 12 nondisabled subjects while they performed a self-selected sitting
pivot transfer from a wheelchair to a level bench. A majority of the
biomechanical variables demonstrated moderate to excellent reliability (r > 0.6).
The transfer measurement system recorded reliable and valid biomechanical data
for future studies of sitting-pivot wheelchair transfers.We recommend a minimum
of five transfer trials to obtain a reliable measure of transfer technique for
future studies.
