The 2012 Provisional PMR Classification Criteria (A Collaborative Initiative of the European League Against Rheumatism and the American College of Rheumatology).
| PMR Classification criteria | Points |
|---|---|
| Clinical Criteria | |
| Morning stiffness duration >45 min | 2 |
| Hip pain or limited range of motion | 1 |
| Absence of rheumatoid factor or anti-citrullinated peptide antibodies | 2 |
| Absence of other joint pain | 1 |
| Ultrasound Criteria | |
| At least one shoulder with subdeltoid bursitis and/or biceps tenosynovitis and/or glenohumeral synovitis (either posterior or axillary), and at least one hip with synovitis and/or trochanteric bursitis | 1 |
| Both shoulders with subdeltoid bursitis, biceps tenosynovitis, or glenohumeral synovitis | 1 |
Required criteria for all cases: (1) age 50 or older; (2) bilateral shoulder pain; (3) elevated ESR and/or CRP.
With only clinical criteria, a score of >4 is required. With combined clinical and ultrasound criteria, a score of >5 is required. The required score has 68% sensitivity and 78% specificity for discriminating PMR from comparison patients. The positive predictive value is 69%, and the negative predictive value 77%.
