Abstract des Autors

The effect of physical activity to the joint-protecting musculature and the bone seems to support the durability of the total arthroplasty. Inactivity and obesity are risks for the early loosening of the prosthesis. The criterion for the load and functional capacity of the patients are not clear. Deficits in strength and especially in strength endurance could not be explored in the consulting room but are frequently existent in these patients. These deficits remaining after rehabilitation in patients with osteoarthritis and prosthesis are described in detail. Objectively and quantitatively reproducible measurements must be recorded for patients prior to rehabilitative training with dynamic and static strengthening exercises, since individual training is not otherwise possible. From the point of time, therapy must begin prior to surgery when the diagnosis is first made and may not stop six month after surgery. The integration of lower cost sports therapeutic measures, such as in sports groups, is indicated due to the constantly ageing population with an increasing rate of arthritis given the continuously increasing costs and reductions in budgets. Training effects can be demonstrated up to 2 years after progressive rehabilitation and thus have long term effect. Verf.-Referat
