Physical activity despite osteoarthritis increases quality of life

A wide variety of health benefits can achieved by people with osteoarthritis simply by increasing their level of physical activity, says a study presented at the American College of Rheumatology annual meeting in San Diego.

Data on physical activity levels in adults with or at risk of knee osteoarthritis was analysed. Participants were part of the Osteoarthritis Initiative, which involved more than 4,700 people.
