In 78.3% of our patients, the sides of SIJ hypomobility and LDH were the same. After treatment, the patients showed statistically significant improvements in Gillet, standing flexion and sitting flexion tests in the 5th session and at 1-month follow-up (P ≤ 0.001). The findings also indicated 95% improvement in the results of the SIJ hypomobility tests after SMT. We also observed a 20% improvement in the SLR test results and a 15% improvement in the slump test in the 5th session and at 1-month follow-up after SMT, although these changes were not statistically significant (Table 3).Table 3Distribution of improvements in diagnostic test results in the 5th session and after 1-month follow-upTest5th session1 month(Positive/Negative)P-value(Positive/Negative)P-valueGillet1/19< 0.001*1/19< 0.001*Standing flexion1/19< 0.001*1/19< 0.001*Sitting flexion1/19< 0.001*1/19< 0.001*SLR16/40.1217/30.25Slump17/30.2517/30.25Abbreviations: SLR straight leg raising*Significant recovery compared to baseline
