🦴 2012 ACR/EULAR PMR Classification
UseWhen to use: age≥50 with bilateral shoulder aching and raised CRP/ESR when PMR classification is considered.
StrataMeets threshold → classifies as PMR; always screen clinically for GCA.
LimitsWhen not to use: without entry criteria, or when late-onset RA better… · Pitfall: missing GCA red flags (vision, jaw claudication, new headach… · Classification ≠ automatic steroid protocol.

When to use
When to use: age≥50 with bilateral shoulder aching and raised CRP/ESR when PMR classification is considered.
How it works
Morning stiffness>45 min (2) + hip pain/ROM (1) + RF/ACPA neg (2) + no other joints (1) ± US (both shoulders 1; shoulder+hip 1).
Key points
- Entry triad required.
- Threshold 4 vs 5 with US.
- Next: GCA assessment; CN rheumatology PMR guidance on zh.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Age ≥50 + bilateral shoulder aching + abnormal CRP and/or ESR | No |
|---|---|
| Morning stiffness > 45 minutes | No (0) |
| Hip pain or limited hip ROM | No (0) |
| RF and/or ACPA negative | No (positive) (0) |
| Absence of other joint involvement | No (other joints involved) (0) |
| Ultrasound available / used in scoring? | No US pathway (threshold ≥4) |
| US: both shoulders abnormal | No / N/A (0) |
| US: ≥1 shoulder AND ≥1 hip abnormal | No / N/A (0) |
→ACR/EULAR PMRNot applicable
- Entry：Needs age≥50, bilateral shoulder aching, abnormal CRP/ESR.
| Age ≥50 + bilateral shoulder aching + abnormal CRP and/or ESR | Yes (required) |
|---|---|
| Morning stiffness > 45 minutes | Yes (2) |
| Hip pain or limited hip ROM | Yes (1) |
| RF and/or ACPA negative | Yes — negative (2) |
| Absence of other joint involvement | Yes — absent (1) |
| Ultrasound available / used in scoring? | US pathway (threshold ≥5) |
| US: both shoulders abnormal | Yes (1) |
| US: ≥1 shoulder AND ≥1 hip abnormal | Yes (1) |
→PMR score8
- Threshold：≥ 5 (with US)
- Classification：Classifies as PMR

FAQ
Frequently asked questions
- Does 2012 ACR/EULAR PMR Classification upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is 2012 ACR/EULAR PMR Classification calculated in practice? Can you show a worked example?
- Inputs: Age ≥50 + bilateral shoulder aching + abnormal CRP and/or ESR No, Morning stiffness > 45 minutes No (0), Hip pain or limited hip ROM No (0), RF and/or ACPA negative No (positive) (0), Absence of other joint involvement No (other joints involved) (0), Ultrasound available / used in scoring? No US pathway (threshold ≥4), US: both shoulders abnormal No / N/A (0), US: ≥1 shoulder AND ≥1 hip abnormal No / N/A (0) → Result: ACR/EULAR PMR Not applicable（Entry: Needs age≥50, bilateral shoulder aching, abnormal CRP/ESR.） Inputs: Age ≥50 + bilateral shoulder aching + abnormal CRP and/or ESR Yes (required), Morning stiffness > 45 minutes Yes (2), Hip pain or limited hip ROM Yes (1), RF and/or ACPA negative Yes — negative (2), Absence of other joint involvement Yes — absent (1), Ultrasound available / used in scoring? US pathway (threshold ≥5), US: both shoulders abnormal Yes (1), US: ≥1 shoulder AND ≥1 hip abnormal Yes (1) → Result: PMR score 8（Threshold: ≥ 5 (with US), Classification: Classifies as PMR）
