In this clinical longitudinal study short-, medium-, and long-term influences of a stationary, balneological rehabilitative treatment on patients with artificial knee and hip joints are investigated. 189 potential patients have been acquired, of which 86 persons completed all planned measurements. In addition to the general positive outcome of rehabilitation and to the subjectively perceived healing success, significant and sustainable improvements at all measuring levels could be observed up to a year after the end of rehabilitation. Standardized indicators of cardial-autonomic regulation, agility, complaints, relaxation, stress, sleep and quality of life or general mood show a significant improvement, whereas individual temporal recovery dynamics of subjective and physical factors can be determined.
