A diagnosis of arthritis may make it seem like your world has literally stopped. With a future full of pain, swelling and limited motion, stopping activity may seem like the only option. Yet, the complete opposite is actually the answer to living a healthy life.Research continually points to the benefits of adding exercise as part of a comprehensive plan for arthritis treatment, and a recent study proves it. Reported at the annual meeting of the American College of Rheumatology (Nov. 2014), the two-year study of 206 adults with hip or knee osteoarthritis (OA) shows that adding either manual or physical therapy (PT) can significantly relieve pain and improve stiffness. Participants received seven weekly therapy sessions and were then instructed to continue prescribed exercises alone, along with three other visits during the study.
