Posterior Innominate Mobilization Versus Muscle Energy Technique on Lumbopelvic Angles in Sacroiliac Joint Dysfunction

Sacroiliac joint dysfunction ( SIJ ) refers to a state of altered biomechanics of the SIJ. The sacrum does not exhibit muscle motion with respect to the ilium and SIJs are slackened only during pregnancy. Excessive or restricted motion may affect extra-articular structures surrounding the SIJs (such as the sacrotuberous, sacrospinus, and/or iliolumbar ligaments) and results in pain.

Sacroiliac (SI) joint dysfunction is a common cause of low back pain and accurate diagnosis can be challenging. A complete history and physical examination are critical in differentiating other diagnosis that may have similar signs and symptoms. Positive response to at least three physical provocation tests suggest sacroiliac joint dysfunction.

Muscle Energy Technique (MET) is an active technique in which the patient is also an active participant. MET is based on the concepts of Autogenic Inhibition and Reciprocal Inhibition. If a sub-maximal contraction of the muscle is followed by stretching of the same muscle it is known as Autogenic Inhibition MET, and if a submaximal contraction of a muscle is followed by stretching of the opposite muscle then this is known as Reciprocal Inhibition MET.

SIJ mobilization is a method of physical therapy. The advantages of the SIJ mobilization are reported in many aspects, such as decrease of LBP, decrease lumbar spinal stress by restoring normal function of innominate, promote pelvic symmetry, correct the sacroiliac joint dysfunction and relax surrounding muscles of the SIJ delimitations are

• Patients suffering from SIJ dysfunction with age between 25 and 45
• Patients with pain in gluteal region and around SIJ.
• Patients testing positive in at least 3 of the following test:
