Journal ArticleDOI
TL;DR: This study found subject weight to be related to pushrim forces and median nerve function and it may be possible to prevent median nerve injury in manual wheelchair users.

Journal ArticleDOI
TL;DR: Specific biomechanical parameters known to correlate with median nerve injuries were found to be related to axle position relative to the shoulder and can improve propulsion biomechanics and likely reduce the risk of injury.

TL;DR: Analysis found significantly higher peak wrist flexion for MWU who demonstrated CTS via the nerve conduction study, suggesting it may be prudent to instruct MWUs to avoid extremes of wrist extension.
Abstract: This study compared wrist kinematics during manual wheelchair propulsion (MWP) for 22 experienced Manual Wheelchair Users (MWU) with and without evidence of median mononeuropathy (MMN), an indicator of CTS. Thirteen (13) MWUs tested positive for MMN. Analysis found significantly higher peak wrist flexion for MWU who demonstrated CTS via the nerve conduction study. It may be prudent to instruct MWUs to avoid extremes of wrist extension.

TL;DR: The electromyographic activity of forearm muscles and pushrim forces were compared between a standard and an ergonomic wheelchair pushrim for a group of non-impaired subjects propelling at two and four miles per hour.
Abstract: The electromyographic (EMG) activity of forearm muscles and pushrim forces were compared between a standard and an ergonomic wheelchair pushrim for a group of non-impaired subjects propelling at two and four miles per hour. The maximum EMG signals were not statistically different for any of the muscles between rims while significantly higher peak tangential, radial, and resultant forces were found for the ergonomic pushrims.

Journal ArticleDOI
TL;DR: The semicircular motion of propulsion displayed characteristics consistent with reduced repetition and more efficient propulsion, which may reduce trauma to the upper extremities and Clinicians should consider training individuals in this propulsion style.

TL;DR: Specific joint forces and moments were related to measures of shoulder pathology, which may indicate a need to reduce the overall force required to propel a wheelchair in order to preserve upper limb integrity.

Journal ArticleDOI
TL;DR: In the light of the current biomechanical and physiological knowledge of manual wheelchair propulsion there seems to be a need for the stimulation of other than hand rim propelled manual wheelchairs.
