This clinical trial is designed to evaluate the combined therapeutic effects of pelvic floor muscle exercises and muscle energy techniques on pain intensity and functional disability in individuals with sacroiliac joint dysfunction. It is commonly linked to altered lumbopelvic mechanics and impaired stability, and interventions that target both joint alignment and deep stabilizing musculature may offer improved clinical outcomes. All participants will undergo baseline assessment, including sacroiliac joint pain provocation tests, pain intensity measured with the Numeric pain rating scale, and functional disability assessed using the Modified Oswestry Disability Index. The intervention will occur three times per week for six weeks, with each session lasting approximately 40-45 minutes. Both groups will receive standard physiotherapy consisting of a hot pack and Transcutaneous Electrical Nerve Stimulation for pain modulation, followed by muscle energy techniques directed at the hamstrings, gluteus medius, piriformis, and iliopsoas to improve muscle balance and sacroiliac joint mobility. The experimental group will additionally participate in a structured pelvic floor exercise program designed to enhance pelvic stability and reinforce load transfer across the sacroiliac joint. Participants will be advised to avoid any external treatments during the study period. Post-intervention assessments will be conducted immediately, after three weeks of treatment and again at six weeks post-treatment to determine both immediate and short-term follow-up effects. This study aims to clarify whether the integration of pelvic floor exercises with traditional muscle energy techniques results in superior clinical outcomes compared to muscle energy techniques alone in the management of sacroiliac joint dysfunction.
