Design outcomes

Primary

MeasureTime frameDescription
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at Week 12Week 12The WOMAC contains 24 questions, including pain for 5 questions, stiffness for 2 questions, and physical function for 17 questions, answered on a range of 0 (mildest) to 4 (most severe). The sum of responses is evaluated as the WOMAC scores.

Secondary

MeasureTime frameDescription
Each WOMAC subscale score at Week 12Week 12The WOMAC contains 24 questions, including pain for 5 questions, stiffness for 2 questions, and physical function for 17 questions, answered on a range of 0 (mildest) to 4 (most severe). The sum of each subscale response is evaluated as the WOMAC subscale score.
Subjective symptoms at Week 12Week 12Assess knee pain, stiffness, discomfort, and health using visual analogue scale. There is a 100 mm straight line with the best and worst degree of sensation indicated at both ends, and the current degree of sensation is marked on the line with the best imaginable state being 0 and the worst state being 100.
