Gender Disparity in Shoulder Pain and ROM among Manual Wheelchair Users

This study explores the relationship between sex, range of motion (ROM), and shoulder pain in manual wheelchair users. Results indicate a higher prevalence of shoulder pain in females, potentially linked to decreased ROM. The study suggests a need for further research to understand this sex difference.

  2. Aim • In manual wheelchair users (MWUs), examine relationship between: • Sex. • Range of motion (ROM). • Shoulder pain. • Relevance • Up to 70% of MWUs experience shoulder pain. • Pain more prevalent in females than males. • Causes of this sex discrepancy not understood, but decreased ROM suggested as major contributor.

  3. Method • Divided 30 MWUs (18 males, 12 females) into 2 groups based on self-reported shoulder pain. • Digital goniometer assessed shoulder active and passive ROMs bilaterally on: • Flexion/extension. • Abduction/adduction. • Internal rotation/external rotation. • Visual analog scale assessed shoulder pain.

  4. Results • 47% of participants reported shoulder pain. • Overall, no-pain group had greater ROM than pain group. • Further analysis revealed this was only significant in females during extension.

  5. Conclusion • ROM impairments were only present in extension in females with shoulder pain. • Mechanism underlying this sex difference is not clear.
