What score classifies PMR?

Score ≥4 (without ultrasound) or ≥5 (with ultrasound) classifies PMR with sensitivity 68%/specificity 78% (without US) or 66%/specificity 81% (with US).

What ultrasound features score in PMR criteria?

Subdeltoid bursitis (bilateral = 1 point), glenohumeral or hip tenosynovitis/synovitis (bilateral = 1 point). Ultrasound confirmation of bilateral shoulder involvement adds 1 point.

What ESR or CRP level is typical in PMR?

ESR >40-50 mm/h and/or elevated CRP are typical but not required for diagnosis. Normal ESR/CRP can occur in ∼20% of PMR cases. Rapid steroid response (>70% improvement in 3-4 weeks) also supports diagnosis.

2012 EULAR/ACR PMR Classification Score

Apply the 2012 EULAR/ACR classification criteria for polymyalgia rheumatica. Scores clinical, laboratory, and ultrasound features to distinguish PMR from mimics including RA, GCA, and inflammatory myopathy.

How It Works

Each component has a specific meaning:

Mimics including RA — The mimics including ra recorded for the scenario being assessed.
GCA — The gca recorded for the scenario being assessed.
Inflammatory myopathy — The inflammatory myopathy recorded for the scenario being assessed.

Note: Interpret the pmr classification result against the thresholds and context described above.

How to Use

Enter the mimics including RA, GCA, inflammatory myopathy for the scenario you are assessing. Apply the 2012 EULAR/ACR classification criteria for polymyalgia rheumatica. Scores clinical, laboratory, and ultrasound features to distinguish PMR from mimics including RA, GCA, and inflammatory myopathy. Use the pmr classification result to inform your calculation.
