Primary Outcome Measures
NameTimeMethod
Self-report measure of exercise adherence over the last 3-months on a numeric rating scale24 month

Exercise adherence was assessed by the single self-report item "How would you rate your level of adherence to the prescribed BOOST exercise program, over the last 3 MONTHS?" Participants selected a number from 0 (not at all) to 10 (completely as instructed). Higher scores reflect better adherence.

Secondary Outcome Measures
NameTimeMethod
Exercise qualityAverage measure of exercise quality over 24 months

The outcome will be assessed at the end of the 24 month follow-up period as the number of calendar periods (1 month per calendar period) that the participant exercises at least half the number of prescribed sessions (a minimum of 6 out of 12 over a 4 week period) with the agreed upon level of intensity.

24 -month change in self-report of pain and function using the WOMAC indexpost the 1-month exercise class, 24 months

The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is a self-administered questionnaire consisting of 24 items divided into 3 subscales:

Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in/out of a car, shopping, putting on/taking off socks, rising from bed, lying in bed, getting in/out of bath, sitting, getting on/off toilet, heavy domestic duties, light domestic duties Responses to individual questions \[between 0 (extreme) and 4 (None)\] are summed to a raw score ranging from 0 (worst) to 96 (best) and then normalized to a WOMAC Score of between 0 (worst) to 100 (best). The difference in pain and function subscale values between the measures following the exercise class and the 24-month follow-up were used for secondary outcomes.

Quadriceps strengthChange in quadriceps strength from baseline to 24 months.

Isokinetic quadriceps strength will be assessed with a Biodex

Timed Physical Function tasksChange in timed physical function task over 24 months

Timed physical function tasks will include a timed get up and go, timed stair ascent and descent, and a 5 and 10 chair stand time. We will examine the association of adherence, as a dichotomous and continuous variable, to change in timed physical function using logistic and linear regression, respectively.
