Back ground: lumbar spine hyperlordosis acombined with excessive anterior pelvic tilting is considered a wide spread postural disorder related to abnormalities in musculoskeletal balance. Although there were a lot of studies have reported that anterior pelvic tilting is correlated to sacroiliac joint, hip dysfunction and knee pain, fewer studies have been showed its effect on low back pain. The purpose: this study was conducted to investigate the effect of posterior iliosacral joint manipulation on subjects with hyperlordosis of lumbar spine. Material and methods: Thirty subject of both genders with age ranged from 20-40 years and body mass index ranged from 18, 5 to 24, 9 kg/m2 assigned in one group and iliosacral joint manipulation was done one shoot, hyperlordosis of lumbar spine was measured by photographic analysis (Surgimap spine software), while special subjective ISJ tests were used to determine the affected limb side (right or left) and the direction of tilting (anterior or posterior) of ISJ, anterior pelvic tilting was measured by inclinometer and pain intensity was measured by numerical rating scale pre and post immediately. Results: there was a significance difference in the mean values of anterior pelvic tilting in the pre and immediate post treatment tests, (8.86±0.77) and (4.86±0.68) degrees respectively (F=535.385, p< 0.0001) and also there was a significance difference in the mean values of pain level in the pre and post immediate treatment tests, ( 5.8±1.44) and (5.03±1.32) degrees respectively (F=29.445, p< 0.0001).Conclusion: posterior iliosacral joint manipulation has increased the sacroiliac joint range of motion and decreased sacroiliac pain in subjects with hyperlordosis of lumbar spine
