Physical functioning questions cover everyday activities such as stair use, standing up from a sitting or lying position, standing, bending, walking, getting in and out of a car, shopping, putting on or taking off socks, kellgren and lawrence grading of osteoarthritis knee in bed, getting in or out of a bath, sitting, and heavy and light household duties. Versions of the WOMAC have also been developed that can be used in telephone or online surveys.
The WOMAC is among the most widely used assessments in arthritis research. It has been translated into more than 65 languages. The American College of Rheumatology notes that the test-retest reliability of the WOMAC varies for the pain, stiffness, and function subscales. The ACR says the pain subscale «has been variable across studies but generally meets the minimum standard.
Reliability for the physical function scale «has been more consistent and stronger but the stiffness subscale has shown low test-retest reliability. When used in clinical studies, the WOMAC pain and function subscales perform comparably or better than other tests in being responsive to change from experimental interventions, but this varies for the different subscales and types of intervention.

What causes it and how is it measured and scored? What Does Joint Space Narrowing Reveal? X-ray images can detect joint space narrowing.
In healthy joints, there is a normal amount of space between the ends of the bones that form the joint. The ends of the bones in a joint are covered by articular cartilage. Articular cartilage serves as the cushion and shock absorber within the joint. Evaluating arthritis usually involves measuring the joint space and judging whether it has narrowed. It varies in the different knee compartments of the same knee and surfaces of the hip joint affected.
