One leg testing in hip and knee osteoarthritis - a comparison with a two-leg oriented functional outcome measure and self-reported functional measures

To compare the responsiveness of two unilateral lower-limb performance-based tests, the one-leg rise test and the maximal step-up test, with the bilateral 30-second chair-stand test and the self-reported measure of physical function (HOOS/KOOS). Specific aims were to evaluate responsiveness, floor/ceiling effect and association between the instruments.
