The sacroiliac joint dysfunction syndrome (SIJDS) is an ongoing controversial issue and an important source of low back pain (LBP). It has been emphasized in many studies that the pathologies of sacroiliac joint (SIJ) are a source of pain in the lumbar spine and hip region. The prevalence of SIJDS in patients with chronic mechanical LBP is between 15 and 30% SIJD is a condition in which pain arises from the sacroiliac joint and is caused by the abnormal movement of ilium around the sacrum and abnormal function of the SIJ structures, like ligaments, muscles, capsules. The prevalence of SIJP has been stated to be up to 75% in LBP patients.~Physiotherapy techniques are used to correct SIJ mal-alignment manually by restoring the normal function and balance of lumbar and pelvic muscles and ligaments. Mulligan described the positional fault theory in which articular mal-alignment leads to altered kinematics and eventual dysfunction(2). Proprioceptive neuromuscular facilitation (PNF) is a form of flexibility exercises used to resolve muscle shortening and strain.
This study will aim to compare the effects of mulligan mobilization and PNF on pain and disability with patients of SIJ dysfunction and will be helpful for clinical physiotherapist to choose more effective treatment protocol for patients as there are fewer researches on comparison of these techniques.
