Design outcomes

Primary

MeasureTime frame
The total score of Japanese Knee Osteoarthritis Measure (JKOM) * Compare the amount of change between screening (before consumption) and 12 weeks after consumption

Secondary

MeasureTime frame
1. JKOM Assess the total score of JKOM and the scores of visual analogue scale (VAS), pain and stiffness in knees, conditions in daily life, general activities, and health conditions 2. The Japanese Orthopaedic Association score for osteoarthritic knees (JOA) Assess JOA scores (the average in both legs, right leg, and left leg) 3. Subjective symptoms related to knee pains (VAS) 4.
