Candidate criteria were evaluated in a 6\u2010month prospective cohort study of 125 patients with new\u2010onset PMR and 169 non\u2010PMR comparison subjects with conditions mimicking PMR. A scoring algorithm was developed based on morning stiffness &gt;45 minutes (2 points), hip pain\/limited range of motion (1 point), absence of rheumatoid factor and\/or anti\u2013citrullinated protein antibody (2 points), and absence of peripheral joint pain (1 point). A score \u22654 had 68% sensitivity and 78% specificity for discriminating all comparison subjects from PMR. The specificity was higher (88%) for discriminating shoulder conditions from PMR and lower (65%) for discriminating RA from PMR. Adding ultrasound, a score \u22655 had increased sensitivity to 66% and specificity to 81%. According to these provisional classification criteria, patients \u226550 years old presenting with bilateral shoulder pain, not better explained by an alternative pathology, can be classified as having PMR in the presence of morning stiffness &gt;45 minutes, elevated C\u2010reactive protein and\/or erythrocyte sedimentation rate, and new hip pain. These criteria are not meant for diagnostic purposes.<\/jats:p>","DOI":"10.1002\/art.34356","type":"journal-article","created":{"date-parts":[[2012,3,4]],"date-time":"2012-03-04T15:12:44Z","timestamp":1330873964000},"page":"943-954","source":"Crossref","is-referenced-by-count":312,"title":["2012
