The innominate up slip dysfunction is the most common in athletes and non-athletes, who present with low back pain and sacroiliac dysfunction. The main muscular structure that forms the force closure of the joint involves the bicep femoris and gluteus maximus that are involved in the stability of the of the pelvis through immense attachments through the Sacro-tuberous ligament. The objective of this study is to determine the effectiveness of Post Isometric Relaxation (PIR) of Quadratus lumborum with and without Gluteus maximus activation on pain, disability and pelvic tilt angle in patients with innominate upslip suprapubic dysfunction.

The study will be a randomized controlled trial involving 34 patients both males and females aged 20 to 40 years with history of unilateral pelvic pain not radiating to L5 or above, Positive finding of sitting flexion test, standing flexion tests, stork test and Positive active straight leg raise test will be randomly recruited by consecutive sampling technique. The subjects having ankylosing spondylitis, lumbar radiculopathy, spinal pathologies, or any lumbar fracture will be excluded. All the patients in the study will be randomly assigned into two groups where Group A will be given muscle energy technique of quadratus lumborum along with gluteus maximus activation and Group B will be a control group treated with muscle energy technique only. Both groups will be given buttock squeezing and drawing in maneuver as common treatment along with muscle energy technique. Each session will be repeated for 20 minutes thrice a week. The treatment duration will be 4 weeks. Outcomes will be measured at the first day and then at the end of the 4th week by numeric pain rating scale, modified Oswestry disability index and iHandy inclinometer application. .
