Definition

Inflammatory back pain is part of the symptoms that lead to Spondyloarthritis og Bekheterevs disease in some cases. However, only about XNUM% develop such disease (reference: Wang R, 2018). The criteria for inflammatory back pain are therefore not suitable for making such a diagnosis without additional studies involving a thorough clinical examination, MR and HLA-B27 in the blood.

Criteria for inflammatory back pain

There are at least three versions of criteria for inflammatory back pain: Calin A, 1977, Rudwaleit M, 2006 and ASAS IBP (Sieper J, 2009). These are largely overlapping and pervert: Symptoms of birth before 40's age, duration of at least 3 months, recovery of physical activity, no relief of rest, night pain relieved when standing up and moving.

Rudwaleit's definition has the highest specificity (81%, sensitivity 70%) and is reproduced below:

Inflammatory back pain (reference: Rudwaleit M, 2009):

  • Morning stiffness in the back for at least 30 minutes
  • Improvement by physical activity, not to be at rest
  • Wake up in the second half of the night because of pain
  • Alternating pelvic pain (gluteal)
