Hydrotherapy Helpful in Osteoarthritis

"Water-based and land-based exercise programs both provide functional improvements over control for patients with osteoarthritis (OA), according to the results of a randomized trial published in the December issue of the Annals of the Rheumatic Diseases. Although strength gain was greater on land, the investigators suggest that water therapy should be used to improve aerobic capacity in those unable to do so on land, and that further studies are needed to demonstrate long-term benefits."
