OBJECTIVE To assess the repeatability of two muscle function measures -- leg extensor power (LEP) and isometric quadriceps force (IQF) -- in a population of patients with osteoarthritis of the knee. DESIGN Repeat measures of LEP and IQF at 25 degrees and 50 degrees knee flexion were taken within seven days. Both legs were measured and a numerical rating scale was used to assess pain on the two occasions.
