Comparative Effects of Two Rehabilitation Approaches on Lumbopelvic Function in Sacroiliac Joint Dysfunction

This research compares two rehabilitation strategies for people with sacroiliac joint dysfunction (SIJD): Dynamic Neuromuscular Stabilization (DNS) and Core Stability Exercises (CSE). SIJD is presented as a biomechanical source of low-back, buttock and leg pain caused by altered joint mechanics, muscle control problems, or asymmetric pelvic alignment; diagnosis relies on clinical provocation tests and exclusion of other causes. The study aims to determine which of the two exercise-based approaches better reduces pain and improves lumbopelvic control. The trial is a single-blinded, parallel randomized controlled trial conducted in an outpatient physiotherapy setting with supervised sessions over four weeks. Adults aged 20-50 with at least three positive SIJ provocation tests and moderate, chronic pain were included; important exclusions were prior spinal/pelvic surgery, systemic inflammatory disease, pregnancy, cardiopulmonary limitation or poor session attendance. Each participant received a baseline conventional physiotherapy package; one arm received a DNS program (breathing-based and developmental movement patterns) and the other performed progressive core-stability training emphasizing transversus abdominis and multifidus activation. Primary outcomes are pain (Numeric Pain Rating Scale) and lumbopelvic stability measured with a pressure biofeedback unit (PBU). Data were collected at baseline and after four weeks; the analysis plan uses SPSS with paired and independent t-tests, ANCOVA to adjust for baseline differences, and effect sizes/confidence intervals to interpret clinical relevance. Safety, informed consent, assessor blinding and standard ethical safeguards are described. The synopsis notes a gap in direct RCT evidence comparing DNS and CSE for SIJD and positions this trial to address that gap with clinical and mechanistic outcomes.
