Suitability of the Oxford Shoulder Score for measuring pain in clinical trials evaluating interventions for people with shoulder disorders according to the OMERACT filter 2.2
Authors' conclusion
The OSS total score shows adequate construct validity and responsiveness, but its combined assessment of pain and function makes it unsuitable for measuring pain alone.
