Change from Baseline at Week 12 in weekly average of average daily knee pain intensity, assessed on the Numeric Rating Scale (NRS)
Query!
Assessment method [1]
0
0
To capture information on the self-reported average knee pain intensity in index knee, over the past 24 hours, participants will be asked to mark their average pain-intensity daily, using the NRS, on an 11-point scale (0-10), with 0 = no pain, and 10 = pain as bad as you can imagine. Daily scores for each participant will be averaged over 7 days to obtain a weekly score.

The WOMAC proprietary set of standardized questionnaires used by health professionals and to evaluate the condition of participants with osteoarthritis of the knee and hip, including pain, stiffness of the joints. The questionnaire covers pain, stiffness and function related to OA in the index knee over the past 48 hours. Participants will respond to each question using an 11- point NRS (0-10), with 0 = no pain/stiffness/difficulty, and 10 = extreme pain/stiffness/difficulty.

The WOMAC is a widely used, proprietary set of standardized questionnaires used by health professionals to evaluate the condition of participants with osteoarthritis of the knee and hip, for physical functioning of the joints. The questionnaire covers pain, stiffness and function related to OA in the index knee over the past 48 hours. Participants will respond to each question using an 11- point NRS (0-10), with 0 = no pain/stiffness/difficulty, and 10 = extreme pain/stiffness/difficulty.
