According to the ESSG criteria, for a patient to be classified as having SpA, he or she has to satisfy one of two entry criteria: Inflammatory spinal pain OR synovitis that is either asymmetric or predominantly in the lower limbs.
Inflammatory back pain: Back pain is common among the general population. However, “inflammatory” back pain is much less common. Back pain is considered inflammatory if four of the following five criteria are found:
Onset of back discomfort before the age of 40 years
Persistence for at least three months
Associated with morning stiffness
Improvement with exercise
Asymmetrical synovitis: Asymmetrical synovitis, predominantly of the lower limbs is manifested by soft tissue swelling, warmth over a joint, joint effusion, and reductions in both active and passive range of motion. As with inflammatory spinal pain, the symptoms are worse after a period of rest.
