M.Tech. / Purpose: To compare the effectiveness of sacroiliac joint adjustments and the combination of sacroiliac and hip joint adjustments in the treatment of sacroiliac syndrome. Method: Thirty participants were randomly divided into two groups with fifteen participants in each group. Group A received sacroiliac joint adjustments and Group B received a combination of sacroiliac and hip joint adjustments. The trial consisted of seven visits over a treatment period of three weeks, of which the first six visits the participants received treatment and the seventh visit served the purpose of getting the final data. The data were gathered on the first, fourth and seventh visits. The data was always gathered before the treatment was performed. Objective data consisted of measuring lumbar range of motion by using the digital inclinometer, and internal and external rotation of the hip joint range of motion, using the goniometer. Subjective data was obtained by using the Numerical Pain Rating Scale (NPRS) and the Oswestry Pain and Disability Index. Results: Objectively, Group B showed statistical significance in right hip internal rotation (p = 0.002), left hip internal rotation (p = 0.001), right hip external rotation (p = 0.002) and left hip external rotation (p = 0.005). Group B hip joint range of motion increased more than Group A. Subjectively, both groups showed a statistically significant decrease in their subjective measurements of pain and its effect on the daily living, as perceived by the participant. There was no statistically significant difference between the groups in the NPRS, but there was a statistically significant difference (p = 0.003) between the groups in the Oswestry Pain and Disability Index. Both the groups showed effectiveness in decreasing the pain over the treatment period. Conclusion: The study showed that the combination of sacroiliac and hip joint adjustments was more effective in treating sacroiliac syndrome. The profession needs to look at the joint surrounding the effected joint as well as the muscular and ligamentous structures.
