• The Wheelchair User’s Shoulder Pain Index (WUSPI) is a simple and effective self-report questionnaire for quickly measuring the functional cost of shoulder pain in wheelchair users.
  • The WUSPI targets activity limitation resulting from shoulder pain (4 subsections), including wheelchair transfers, wheelchair mobility, self-care and general activities. However, it does not obtain information about the type or frequency of pain experienced during the activities.

Equipment

None

Scoring

  • You will need approximately 5 minutes to complete the WUSPI.
  • Each item is scored 0-10 on a 10 cm visual analog scale (VAS).
  • Total score (0-150) is the sum of all item scores.
  • Higher scores indicate greater interference due to shoulder pain.
  • No strategies are suggested to assist with scoring if a person indicates they do not do certain activities (e.g./ load their chair into a car).
