M.Tech. (Chiropractic) / To compare the effectiveness of biomechanical pelvic blocking to segmental drop piece adjustments in the treatment of sacroiliac joint dysfunction. Method: Thirty participants were randomly divided in two equal groups. Group A (n = 15) received biomechanical pelvic blocking and Group B (n = 15) received segmental drop piece adjustments. The trial consisted of seven treatment visits over a period of three weeks, of which the first six were treatment sessions, with the final seventh session serving the purpose of obtaining final post-treatment data. Data was obtained only at the first, fourth, and seventh visits. Subjective data was obtained by having each participant complete a numerical pain rating scale and the oswestry low back pain and disability questionnaire. Objective data consisted of pain pressure threshold over the posterior superior iliac spine by using a pressure algometer. Results: The subjective results showed that there was a decrease in the numerical pain rating scale (NPRS) reading scores over the treatment visits for both groups. Group A had a statistically significant decrease (p = 0.000) in the NPRS reading scores between visit 1 and 4, and a statistically significant decrease (p = 0.000) between visit 4 and 7. Group B showed that there was a statistically significant decrease (p = 0.001) from visit 1 to 4, and a statistically significant decrease (p = 0.002) between visit 4 and 7. According to the Mann-Whitney test both groups showed a statistically significant decrease in their NPRS readings over the treatment period (p = 009), however Group A had a greater decrease in pain than Group B when looking at the mean score values. This indicates that both biomechanical pelvic blocking and segmental drop piece adjustments delivered to the dysfunctional sacroiliac joints are effective in decreasing pain. Over time, statistical analysis showed that there was a decrease in oswestry pain and disability for both groups A and B when looking at the Friedmann and Wilcoxon-signed rank test. Group A showed a statistically significant decrease (p = 0.012) from visit 1 to 4, and a statistically significant decrease (p = 0.002) for visit 4 to 7. Group B also showed that from visit 1 to 4, there was a statistically significant decrease (p = 0.001), and from visit 4 to 7 there was a statistically...
