Abstract

OBJECTIVE: The Osteoarthritis Research Society International (OARSI) recommends assessment of physical function using a performance-based test of stair negotiation but was unable to recommend any specific test. We assessed the reliability, validity, responsiveness, measurement error, and minimum important change (MIC) of the 6-step timed Stair Climb Test (SCT). METHODS: We used pooled data from 397 participants with hip or knee osteoarthritis (54% women) from 4 clinical trials (86% retained at 12-week follow-up). Construct validity was assessed by testing 6 a priori hypotheses against other OARSI-recommended physical function measures. A self-reported Global Rating of Change scale was used..
