- The Sacroiliac Joint Dysfunction may lead to hypermobility or hypomobility at the joint, resulting in pain and irritation. Patient complains of dull aching pain on the affected side. The pain increases during the activities while turning, sitting, bending or acquired standing posture. The pain gets referred to either groin, gluteal region or the posterior aspect of the thigh. With or without associated numbness, in groin region and pain on one side is more common than bilateral. This Sacroiliac joint dysfunction can be managed conservatively using physical agent modalities such as electrotherapy, laser therapy, ultrasound, longwave, rest, exercises, or using manual mobilisation.  Purpose of the Study: To determine the effectiveness of Mulligan Mobilisation and Muscle Energy Technique in Sacroiliac Joint Dysfunction.  Material and Method used: 700 subjects were screened to include 72 subjects with diagnosis of sacroiliac joint dysfunction and further were haphazardly divided into two groups viz. Muscle Energy Technique therapy group and Mobilisation group via block randomization, depending on severity of pain (mild, moderate, severe) using lottery method.  Results: The values of Visual Analogue Scale, Modified Oswestry Disability Questionnaire and Pain Pressure threshold within the group were analysed using Paired ttest and among the groups were analysed using independent t-test.  Conclusion: MET and Mobilisation both techniques are operative in treatment of Sacroiliac Joint Dysfunction.
