Abstract

<p>[Purpose] The purpose of this study was to investigate whether joint function and physical ability differ according to the presence of pain during knee joint extension in knee osteoarthritis (knee OA). [Participants and Methods] Thirty-one female patients with knee OA were included. The presence of pain during knee extension was assessed under three conditions: (1) active knee extension, (2) stepping, and (3) one-legged squatting. In addition, knee extension range of motion (ROM), knee extension strength, 5-meter walking distance (5MWT), Timed Up & Go Test (TUG) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were evaluated. [Results] The WOMAC score was significantly higher, knee extension strength and ROM were significantly lower, and 5MWT (maximum speed) and TUG were significantly slower in the group with pain during active knee extension. Moreover, the group with pain during stepping had a significantly slower 5MWT (comfortable speed). [Conclusion] In patients with knee OA, pain during knee extension was associated with poorer knee joint function and lower gait speed.</p>
