Overview

The diagnosis of PMR is mostly clinical and is supported with an elevated ESR and specific findings on ultrasound of the affected joints. The European League Against Rheumatism/American College of Rheumatology collaborative initiative developed a provisional classification criteria for polymyalgia rheumatica. The following criteria are required: age 50 years, bilateral shoulder aching, and abnormal C-reactive protein (CRP and/or erythrocyte sedimentation rate (ESR).

Diagnostic Criteria

Shown below is the 2012 provisional classification criteria for polymyalgia rheumatica by the European League Against Rheumatism/American College of Rheumatology collaborative initiative. Each of the findings is given a point, then the total score is calculated by adding all the point. Two scores have been developed depending on whether an ultrasound is performed or not.
