Evaluating Erector Spinae Plane Block for Persistent Back Pain in Adults with Ankylosing Spondylitis Under Treatment

What this Trial Is About

Ankylosing spondylitis is a chronic inflammatory disease mainly affecting the spine and sacroiliac joints, causing persistent back pain and stiffness. This research aims to evaluate the effects of the erector spinae plane block, a regional pain-relief technique, on patients who have controlled disease activity under treatment but continue to experience persistent back pain. The study addresses an important need for additional pain management options beyond standard therapies. The erector spinae plane block procedure is performed under ultrasound guidance by injecting a combination of local anesthetic and steroid into a specific muscle plane in the back. This is done twice within one week by experienced specialists. Patients will undergo this procedure and be followed up at baseline, 2 weeks, and 2 months to assess changes in pain and clinical outcomes. Participants will have assessments at three timepoints to measure pain severity, disease activity, spinal mobility, functional status, and back pain-related function. Tools such as the Numeric Rating Scale and various ankylosing spondylitis indices will be used. The study involves regular monitoring of these outcomes to understand the impact of the intervention over two months after treatment.
