In a study of 1,600 adults with osteoarthritis (OA), researchers from Northwestern University found the right amount of time to exercise for sustaining function and keeping pain down. The study showed any activity or exercise is better than none; however, those who did at least 45 minutes of moderate activity (such as fast walking, moderate cycling) had the best functioing and pain scores after a 2 year follow up. Unfortunately only 10% of adults with OA meet the 45 minute goal, many due to the misinformed notion that pain means they are damaging their joints further (a concept debunked by modern pain science). So, get out and move or call your local PT today for a tune-up before you start!
