Background: Sacroiliac joint dysfunction is a frequent cause of lower back pain and the primary contributor of reduced mobility and impaired daily activities. Effective therapeutic interventions are essential for alleviating symptoms. This study investigates and compares the outcomes of mulligan’s mobilization techniques and Lumbosacral exercises program in individuals diagnosed with sacroiliac joint dysfunctions.

Objective: To determine the comparative effects of Mulligan’s mobilization techniques and Lumbosacral exercises on functional disability and pain, measured using Modified Oswestry Disability Index (MODI) and Numeric Pain Rating Scale (NPRS).

Methods: Twenty four patients (15 females and 9 males) with sacroiliac joint dysfunction (SIJD) were randomly assigned into two groups 12 in group A (Mulligan’s Mobilization Techniques)12 and group B (Lumbosacral Exercises) after fulfilling inclusion criteria. Both groups underwent treatment over six weeks. Assessment using outcome measures MODI and NPRS were carried out at baseline, 3^rd week and 6^th week. Data analysis was conducted in SPSS, employing descriptive statistics, repeated measures ANOVA and independent t-test to identify significant differences within and between groups.

Results: Significant improvements in both Functional disability and Pain scores were observed in both groups over the course of treatment (p<0.05). Although both interventions were effective, Group A had slightly greater reduction in Functional disability scores by the third and sixth week but NPRS scoring results were same in both groups showing significant reduction in pain, although not all differences were statistically significant.

Conclusion: Both Mulligan mobilization and Lumbosacral exercises proved beneficial for managing Sacroiliac Joint Dysfunction. Mulligan’s technique may offer slightly enhanced short term benefits, but further research with a larger sample size is recommended to confirm these findings.
