[Generalized tendomyopathy. II: Pathogenesis and therapy].

Many factors are known to play a role in the pathogenesis of generalized tendomyopathy (GTM), or fibromyalgia. While the secondary forms develop along with known diseases, particularly rheumatoid arthritis, the cause of primary GTM is often not well understood. The fact that this disorder usually appears first at a single site, e.g., as low-back pain or cervical syndrome in which poor posture or malformation of the spine can be observed, gives rise to the theory that local changes in the spine or the joints are particular underlying causes of the initial manifestation. As the disorder becomes generalized, however, psychological causes predominate. Psychosocial factors in particular seem to further the process of generalization. Therapy can take many forms. Above all, it calls for an understanding attitude on the part of the managing physician and, whenever, possible, elimination of likely causal factors. Analgesics and antiinflammatories are often inadequate; antidepressants and neuroleptics provide more effective relief. Moreover, intensive physiotherapy and psychotherapy are necessary. GTM in many cases is resistant to treatment despite intensive management, although it often subsides naturally after age 60. Recognizing GTM is of great importance in order to initiate appropriate treatment promptly, avoid incorrect diagnoses and their consequences, e.g., repeat surgery, and to prevent premature disability.
