Objective: To compare the effects of Post Isometric Relaxation (PIR) of gluteus maximus and Static Stretching (SS) of hip flexors on pain and functional status in patients with Anterior Innominate Dysfunction.

Methodology: A quasi experimental trial was conducted on thirty six patients of Anterior Innominate Dysfunction. All were randomly allocated to post isometric relaxation group and static stretching group. Both groups were treated with 12 treatment sessions in 4 weeks at frequency of 3 sessions per week. Numeric Pain Rating Scale (NPRS) and Modified Oswestry Disability Index (MODI) were used to measure the treatment effect at baseline, after 2 weeks and after 4 weeks. Data was analyzed by SPSS 21.

Results: Mean Age of Group A (PIR) was 34.28±7.76 and Group B (SS) was 35.72±7.16. Mean BMI of participants was 23.84±3.29. Across group, both post isometric relaxation and static stretching had shown significant results with P value <0.05. But within group, post isometric relaxation had shown more significant results as compared to static stretching with P value <0.05.

Conclusion: Both treatment techniques; Post isometric relaxation and Static stretching are effective and produced significant difference in NPRS and MODI score to improve pain and functional status but PIR had shown more promising results in patients with anterior innominate dysfunction.
