In both fibromyalgia and rheumatoid arthritis, pain was bilateral, involved multiple sites, and was of equal intensity (60.8 versus 58.7, respectively, on a scale of 100). Fibromyalgia pain, however, was less localized to the joints and suggested greater spatial diffusion. It involved more kinds of pain experiences (radiating, steady, spreading, spasms, gnawing, unlocalized, pricking, crushing, shooting, pressing, splitting, cramping, nagging, and pins and needles), and was dispersed over larger areas of the body. The anatomic sites best for discrimination between patients with fibromyalgia and patients with rheumatoid arthritis were the lower back, thigh, abdomen, head, and hips for fibromyalgia, and wrist, foot, and fingers for rheumatoid arthritis. The traditional clinical description of aching and stiffness does not appear to accurately describe the complexity of the fibromyalgia pain syndrome.<\/jats:p>","DOI":"10.1002\/art.1780290611","type":"journal-article","created":{"date-parts":[[2007,2,14]],"date-time":"2007-02-14T21:10:20Z","timestamp":1171487420000},"page":"775-781","source":"Crossref","is-referenced-by-count":74,"title":["Comparison of pain properties in fibromyalgia patients and rheumatoid arthritis patients"],"prefix":"10.1002","volume":"29","author":[{"given":"Frank","family":"Leavitt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert S.","family":"Katz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harvey E.","family":"Golden","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul B.","family":"Glickman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lawrence F.","family":"Layfer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,29]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"928","article-title":"Two contributions to understanding of the \u201cfibrositis\u201d syndrome","volume":"28","author":"Smythe HA","year":"1977","journal-title":"Bull Rheum Dis"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0049-0172(81)90096-2"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006842-197507000-00008"},{"key":"e_1_2_1_5_2","first-page":"S32","article-title":"Sleep studies in patients with fibrositis syndrome (abstract)","volume":"26","author":"Golden H","year":"1983","journal-title":"Arthritis Rheum (suppl)"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.3.1.56"},{"key":"e_1_2_1_7_2","volume-title":"Primer on the Rheumatic Diseases","author":"Committee of the American Rheumatism Association Section of the Arthritis Foundation","year":"1973"},{"key":"e_1_2_1_8_2","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1016\/S0025-7125(16)31708-4","article-title":"Diagnosis and management of fibrositis syndrome and psychogenic rheumatism","volume":"63","author":"Beetham WP","year":"1979","journal-title":"Med Clin North Am"},{"key":"e_1_2_1_9_2","first-page":"175","article-title":"1958 revision of diagnostic criteria for rheumatoid arthritis","volume":"9","author":"Ropes MW","year":"1958","journal-title":"Bull Rheum Dis"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(75)90044-5"},{"key":"e_1_2_1_11_2","volume-title":"SPSSx Advanced Statistics Guide","author":"Norusis MJ","year":"1985"},{"key":"e_1_2_1_12_2","first-page":"58","article-title":"Differential diagnosis of primary fibromyalgia syndrome","volume":"4","author":"Yunus MB","year":"1983","journal-title":"Intern Med Specialist"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(84)90007-1"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4886(76)90271-5"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(77)90139-7"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(82)90182-8"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(79)90010-1"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780250216"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780271004"},{"key":"e_1_2_1_20_2","first-page":"500","article-title":"Psychological status in primary fibrositis and fibrositis associated with rheumatoid arthritis","volume":"11","author":"Wolfe F","year":"1984","journal-title":"J Rheumatol"}],"container-title":["Arthritis &amp;
