Die Rehabilitation
-
The ninth book of the German social code, SGB IX, has intensified questions on the effectiveness and usefulness of medical rehabilitation, a multimodal multidisciplinary team care model, especially but not exclusively for chronic back pain. In 2002 back pain was the reported leading cause for 29 % of all medical and other rehabilitative services provided by German statutory pension funds. A previous systematic review of all available German studies (January 1980 to June 2001) analysed the effectiveness of inpatient rehabilitation for chronic back pain. The present report provides an update and critical appraisal of the review. ⋯ The small size of medium term effects indicates a basic problem of inpatient rehabilitation for chronic back pain in Germany. This becomes even greater when the results of international controlled studies are used as reference. Possible reasons for the disappointing situation (weak methodology, inappropriate selection of patients, weak intervention) are to be discussed. At present, we have no convincing evidence for a general effectiveness of Germany's system of inpatient rehabilitation for chronic back pain.
