What researchers measure

Primary outcomes

  1. Difference in total Western Ontario and McMaster Universities Arthritis index (WOMAC) score total between D168 and inclusion visit.

    The Western Ontario and McMaster Universities Arthritis index (WOMAC) is a 24-item, condition-specific questionnaire available in a 5-point Likert and 100 mm visual analog scale (VAS) as well as an 11-box numerical rating scale, composed of three subscales: pain (5 questions), stiffness (2 questions) and physical function (17 questions). VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)

    Time frame: 168 days

Secondary outcomes

  1. Change in pain measurements, assessed using the Western Ontario and McMaster Universities Arthritis (WOMAC) pain severity index, as compared to D0

VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)

    Time frame: up to 168 days

  2. Change in the Western Ontario and McMaster Universities Arthritis (WOMAC) functional severity index, as compared to D0

VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)

    Time frame: up to 168 days

  4. Pain at walking on a 100 mm VAS

    Time frame: up to 168 days

  5. Percentage of subjects using analgesics

    New NSAID / analgesics drugs usage

    Time frame: up to 168 days

  6. Measurement of relief satisfaction by the patient

    7-point Likert scale (1 point very unsatisfied to 7 points for very satisfied)

    Time frame: 168 days

  7. Measurement of therapeutic efficacy by the investigator (assessor)

    7-point Likert scale (1 point very unsatisfied to 7 points for very satisfied)

    Time frame: 168 days
