Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) A Pain Score | Week 12 | The pain score is based on a score of 0 to 4; the higher the score, the higher the amount of pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Weekly Average of Daily Knee Pain Scores by VAS | Week 26 | Knee pain will be assessed on a score of 0 to 100; the lower on the scale, the less the amount of knee pain experienced. Weekly post-baseline average daily knee pain scores will be calculated. |
| Change From Baseline in Weekly Average of Daily Global Pain Scores by VAS | Week 26 | Global pain will be assessed on a score of 0 to 100; the lower on the scale, the less the amount of global pain experienced. Weekly post-baseline average daily global pain scores will be calculated |
