Reliability and Validity of the Osteoarthritis Research Society International Minimal Core Set of Recommended Performance-Based Tests of Physical Function in Knee Osteoarthritis in Community-Dwelling Adults

摘要

The proper reliability analysis for specific type of data and limit study of various types of construct validity are crucial for performance-based tests for the knee osteoarthritis (OA) population. The purpose of this study was to evaluate relative and absolute reliability and construct validity of the Osteoarthritis Research Society International (OARSI) recommended minimal core set of performance-based tests in knee OA in community-dwelling adults.
