WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee or index hip during past 48 hours. It was calculated as mean of the scores from the 5 individual questions scored on a numerical rating scale (NRS) of 0 to 10, where higher scores indicated higher pain. Total score range for WOMAC pain subscale score was 0 to 10, where higher scores indicated higher pain. |
