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 bursitis2.6 (1.3 to 5.3)1§
Both shoulders with subdeltoid bursitis, biceps tenosynovitis or glenohumeral synovitis2.1 (1.2 to 3.7)1
  • ACPA, anticitrullinated protein antibody; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; RF, rheumatoid factor; CI, confidence interval.

  • * The optimal cut point is 4. A patient with a score of 4 or more is categorised as having polymyalgia rheumatica (PMR).

  • The optimal cut point is 5. A patient with a score of 5 or more is categorised as having PMR.

  • § P = 0.008.
