The control group was treated with electroacupuncture and the study group was treated with LONG's chiropractic therapy.

Results： The total effective rate was 94.29% in the study group，and 77.14% in the control group，the difference being significant(P＜0.05)． Before treatment，there was no significant difference in the comparison of scores of symptoms and signs between the two groups(P＞0.05)．After treatment，scores of symptoms and signs in both groups were decreased when compared with those before treatment(P＜0.05)， and the above scores in the study group were lower than those in the control group(P＜0.05)． After treatment，the levels of obturator width difference，hip width difference，iliac crest height difference and femoral neck length difference in the study group were all smaller than those in the control group，differences being significant(P＜0.05)． Conclusion： LONG's chiropractic therapy for patients with rotated pelvic syndrome， can improve the clinical effect and clinical symptoms and signs， and correct the pelvic displacement， whose effect is better than conventional electroacupuncture therapy.
