Rehabilitation in rheumatic diseases and osteoporosis-a multidisciplinary taskAdvances in medications and changes in therapeutic options have significantly reduced limitations in functional capacity and quality of life for patients with rheumatic diseases and osteoporosis, but there is still a large number of patients in whom the diseases do not take the desired course. Older rheumatic patients also often have comorbidities that require a multidisciplinary and multimodal approach to therapy. Rehabilitation measures are, therefore, an important part of the treatment concept for these patients in order to maintain their functional health, social participation, and, in the case of those who are still working, in particular their gainful employment. They can help to limit sequelae, preserve existing functions, reduce pain, and maintain the quality of life of those affected. The article aims to provide an overview of the rehabilitative therapy concept and the level of evidence for individual forms of therapy.
