Identifying reliable, valid and feasible outcome measures for adults aged 50 years or older with hip or knee osteoarthritis participating in supervised exercise programs: a scoping review

Multiple outcome measures demonstrated acceptable reliability and validity for adults with hip or knee OA, but feasibility data were limited, and no tools were validated in the context of supervised exercise. Consequently, no measure fulfilled all three psychometric criteria for this setting. Future research should include structured feasibility assessments and evaluate measures within exercise-based interventions.
