Exercise is one of the best treatment options for individuals with osteoarthritis. It can help them regain flexibility and functionality while increasing strength levels. Building muscle strength around affected joints helps alleviate stress from those joints. Additionally, exercise can help individuals with osteoarthritis lose weight, taking excess strain off of joints. For example, research has shown (Messier, 2005) that losing one pound can result in four times as much pressure being removed from knee joints. For these reasons, as well as all other associated benefits of exercise and physical activity, individuals with osteoarthritis should incorporate daily exercise into their lifestyles.
