Background: The sacroiliac joint (SI) has long been thought to be a cause of lower back and/or buttock discomfort, with or without symptoms in the lower limb.

Objective: To determine the role of gluteus maximus strengthening with hamstring release by traction straight leg raise technique among subjects having sacroiliac joint dysfunction.

Methodology: It was a randomized clinical trial conducted at Sports and Spine professionals. Trial was registered in Clinical Trial Registry and the registration number is NCT04757415. Total 38 diagnosed patients with Sacroiliac joint (SI) syndrome were involved in this research with convenient sampling method. The subjects were divided randomly into two groups using the concealed envelope method. Group 1 patients got Gluteal activation exercises along with traction straight leg raise technique of Mulligan while Group 2 got just gluteal activation exercises. Heating pad was applied to both groups. The goniometry, the sphygmomanometer, NPRS Scale and Oswestry disability index are data collection tools to evaluate all patients before and after 5 weeks of treatment. Statistical examination was calculated by SPSS 20.0.

Results: There is statistically significant difference in results of NPRS in between group analysis. Pain decreased to greater extent in post treatment of Group 1 with mean value 2.15±0.83 as compared to 9.10±13.79 of Group 2. OSWESTRY Disability Index decreased to greater extent in post treatment of group 1 with mean value 11.31 ±1.68 as compared to Group 2 with mean value 22.47± 2.36. Hamstring range of group was increased to significant value with mean value 76.84±9.71 as compared to mean value of group 2 which was 38.56±3.70. Gluteus muscle strength was noticed in group 1 with mean value 70.42±8.68as compared to group 2 with mean value39.52±4.11.

Conclusion: Results of this study shows statistically as well as clinically significant results in terms of NPRS, OSWESTRY Disability Index, hamstring range and gluteal muscles strength. It was indicated that combination of gluteal activation along with straight leg raise technique by mulligan was helpful in pain relief, improving range of movement, strength and daily life activity status in patients with sacroiliac joint syndrome.
