  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.
