Criteria for Fibromyalgia To reduce misdiagnosis and confusion, the American College of Rheumatology (ACR) recognized the need to establish a clear definition and guidelines. They sponsored a multicenter study to develop these criteria. The diagnostic criteria include 2 basic requirements. The first is the presence of pain in all 4 quadrants of the body, as well as in the axial skeleton on a more or less continuous basis for at least 3 months. The pain often is described as widespread or global. The second criterion is the presence of at least 11 of 18 anatomically specific tender points. A tender point hurts only at the area where pressure (enough to cause the examiner's nail bed to blanch, or about 4 kg) is applied, and there is no referred pain. An instrument known as a dolorimeter can be used to apply exactly 4 kg of pressure over the tender points during the examination. The 18 possible tender points exist as 9 pairs. Tender points may be found in any palpable muscle, but 18 sites are consistently present
