Time Frame: Baseline, Weeks 8, 16, and 24
|
WOMAC physical function subscale is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in the index joint (knee or hip) in the past 48 hours.
It is calculated as the mean of the scores from the 17 individual questions scored on a NRS of 0 to 10, where higher scores indicate worse function.
Total score range for WOMAC physical function subscale score is 0 to 10, where higher scores indicate worse function.

Time Frame: Baseline, Weeks 8, 16, and 24
|
Participants answered: Considering all the ways your osteoarthritis in your knee or hip affects you, how are you doing today?
Participants rated their condition using a 5-point scale where 1 = very good (asymptomatic and no limitation of normal activities), 2 = good (mild symptoms and no limitation of normal activities), 3 = fair (moderate symptoms and limitation of some normal activities), 4 = poor (Severe symptoms and inability to carry out most normal activities) and, 5 =very poor (Very severe symptoms which are intolerable and inability to carry out all normal activities).
Higher score indicated severe condition.

Change From Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Physical and Mental Component Scores at Week 24
Time Frame: Baseline, Week 24
|
SF-36v2 is a self-administered questionnaire evaluating 8 aspects/domains of functional health and wellbeing: physical function, role physical, bodily pain, vitality, general health, social function, role emotional and mental health.
Total score for each aspect were scaled 0-100(100=highest level of functioning).
For obtaining physical and mental component scores, z-score for each scale=(observed score - mean score for general 1990 United States [US] population)/corresponding standard deviation.
The 2 component scores were obtained by multiplying each aspect z-score by physical or mental factor score coefficient (1990 general US population) and summing the eight products.
Component scores indicated how many standard deviations higher (in case of positive z-score [better functioning])/lower (in case of negative z-score [worse functioning]) participant's value was relative to the mean of the reference population.
Change from baseline >0 indicates an improvement.
