Sacroiliac joint (SIJ) dysfunction is known as an important contributing factor in lower back pain. Pain and stiffness experienced from the sacroiliac joint in the SI region (hips/groins or may spread to lower extremity) is referred as SIJ dysfunction.Physiotherapists have a wide range of options in managing SIJD including Manipulation, Kinesiotaping, Muscle Energy Technique (MET), McKenzie, Maitland's mobilization, and Mulligan's mobilization. So far studies have shown the efficacy of different treatment tools in combination or in isolation. Likewise, researchers have also studied the effect of piriformis stretch in combination with other exercises on sacroiliac joint pain. However, there is very limited literature available on the cumulative effect of piriformis stretch along with mobilization maneuvers on pain and disability in patient with SIJ dysfunction.Since piriformis is one of the most important muscles involved in stabilization of SI joint and a major source of SI dysfunction, hence the current study is designed to investigate the additional effects of piriformis stretch with manual therapy in the management of sacroiliac joint dysfunction.

SIJ dysfunction is a prominent source of pain in low back pain patients. It is reported that 10-30% of individuals suffering from lower back pain is due to SIJ dysfunction.There are different risk factors for developing SIJ dysfunction including leg length discrepancies, a history of lumbar fusion, scoliosis, sustained athletic activity, pregnancy, spondyloarthropathies, or gait abnormalities.Muscles that are commonly found to be shortened (or tightened) in SIJ dysfunction include the rectus femoris, tensor fascia Lata, hip adductors, quadratus lumborum, piriformis, obturator internus, and latissimus dorsi. Particular attentions should be directed to the piriformis muscle. t alters the SIJ motion by rotating the sacrum to the opposite side.Continued inflexibility of this muscle is often thought to be part of the source of recurrent pain Over time several treatment aporaches have been developd to treat SIJ dysfunction.Clinicians also use different electrotherapy modalities, biomechanical correction techniques, and exercises for addressing SI joint pain. Many therapeutic exercises including piriformis stretch, muscle activation exercises and exercise therapy have the potential of improving sacroiliac joint dysfunction , however evidence is deficient. This research presents additional effects of piriformis stretch in the management of sacroiliac joint dysfunction.It will expand current understanding of effects of piriformis stretch on disability and pain in patients with SIJ dysfunction and help in providig treatment protocols for improving pain in patients with sacroiliac joint dysfunction.

Main objective of thi study is to determine and compare the effect of piriformis stretch along with mobilization as compared to SIJ mobilization alone on pain and disability in patients with SIJ dysfunction.

The participants meeting the eligibility citeria will be recruited, followed by random allocation to 2 groups. Both groups will recive standard treatment protocol which consists of Hot pack TENs, mobalization.Three sessions will be provided on alternative days. Pre and Post assessment of pain and disability will be noted
