Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Summary
What it measures:
- The WOMAC is a disease-specific tool used for people with hip or knee OA to measure physical function, pain, and stiffness in the past 48 hours.
- The WOMAC is a self-administered instrument containing 24 items measuring 3 subscales: physical function (17 items), pain (5 items), and stiffness (2 items).
- Scores can be calculated for each subscale and a total score is calculated by adding all 3 subscale scores. Higher points signify higher levels of functional difficulty.
Target Population:
Adults with hip or knee osteoarthritis (OA), although it has also been used in populations with low back pain, rheumatoid arthritis (RA), juvenile RA, systemic lupus erythematosus, fibromyalgia, and post-lower extremity arthroplasty.
