[Localized pressure pain in the diagnosis of generalized tendomyopathy (fibromyalgia)].

56 tender points were examined in 100 patients and 50 age- and sex-matched healthy volunteers using a dolorimeter. 24 of the 56 points were especially selected according to ability of discrimination, best possible distribution on the body, and easy localization. All 56 points as well as the 24 specially selected points were examined as to their sensitivity and specificity in the diagnosis of generalized tendomyopathy. The sensitivity and the specificity for both point-combinations were acceptable. The sensitivity and specificity of the 24 points were superior to the 56 points in the case of discrimination ability. A 100% sensitivity and specificity could not, however, be achieved. It remains to be considered if functional and vegetative symptoms must still be used to support the diagnosis of generalized tendomyopathy (fibromyalgia).
