Abstract:
Study examined the relationship between wheelchair pushrim biomechanics and progressive shoulder injury in manual wheelchair users. Biomechanical data were obtained on 14 subjects with spinal cord injury who used manual wheelchairs. Magnetic resonance images (MRIs) of both shoulders were completed for each subject on 2 occasions, approximately 2 years apart. Differences between the first and second and MRI scores were calculated and subjects were divided into 2 groups based on change in score. Seven subjects were in the group with worsening scores (MRI+) and 7 were in the group with improving or unchanging scores. There were significantly more women in the MRI+ group. This group used significantly greater force directed toward the axle to propel their wheelchairs at the time of the first MRI.
