Ostheoarthritis (WOMAC)

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a widely used, proprietary set of standardized questionnaires used by health professionals to evaluate the condition of patients (in this case: Lifelines participants) with osteoarthritis of the ankles, knees and hips, including pain, stiffness, and physical functioning of the joints (section: diseases & symptoms).
It can be self-administered and was developed at Western Ontario and McMaster Universities in 1982.

The WOMAC measures the following dimensions of osteoarthritis of hips, knees, and ankles:

pain (5 items, score range 0–20)
stiffness (2 items, score range 0–8)
functional limitation (17 items, (score range 0–68).
