Validating new criteria for diagnosing axial spondyloarthritis
Part of Bones, joints & muscles clinical trials.
This study aims to confirm new classification criteria for axial spondyloarthritis, a type of inflammatory arthritis affecting the spine and sacroiliac joints. Participants with chronic back pain lasting at least 3 months and starting before age 45 will undergo a series of tests to see if these new criteria better identify the condition.
Summary written for real people, not researchers, by Clin2.
