OSTEOARTHRITIS
At each monthly visit, participants completed The Knee Injury & Osteoarthritis Outcome Score (KOOS), to assess five separate dimensions: Pain (nine items), symptoms (Sx) (seven items), ADLs (17 items), sport and recreation function (Sport) (five items), and knee-related quality of life (QOL) (four items) [The Veterans Rand 12 Item Health Survey (VR-12), a 12-item survey, was administered at each monthly visit to assess mental and physical health component scores (MCS and PCS). The MCS emphasizes mental health and social functioning, while the PCS assesses physical function and pain. VR-12 scores are standardized using a T-score metric ranging from 0-to-100, with a mean score of 50 for the general population. Increasing values indicate more favorable outcomes [Physical activity was assessed at each monthly visit via the following survey questions: 1) How many minutes per week do you participate in low to moderate intensity cardiovascular training? 2) Please list the types of low to moderate intensity cardiovascular type exercises. 3) How many minutes per week do you participate in high to vigorous intensity cardiovascular training? 4) Please list the types of high to vigorous intensity cardiovascular type exercises. 5) How many minutes per week do you participate in strength training? 6) Please list other types of exercises. These questions were used to quantify minutes per week on average of the following types of exercise: 1) low to moderate intensity aerobic, 2) vigorous intensity aerobic, 3) strength training.
