Effect of Structured Info and Adapted Exercise in OA

Physical activity level is measured at baseline and after 3 and 12 months after structured information and individually adapted exercise for patients with osteoarthritis in hip or knee. The hypothesis of this study is that a supported self management of osteoarthritis program will increase the level of physical activity in patients with osteoarthritis in hip or knee. The second hypothesis is that patients with osteoarthritis in knee will increase their level of physical activity more than patients with osteoarthritis in hip.
