Analysis of the Relation between Uterine Position and the Effect of Sanyinjiao (SP6) in Patients with Primary Dysmenorrhea / 上海针灸杂志

ABSTRACT

ObjectiveTo explore the relation between the uterine position and acupoint effect by analyzing the data of a clinical trial of electroacupuncture in treating primary dysmenorrhea.MethodThe uterine position was detected by ultrasonic examination;Visual Analogue Scale (VAS) was used to evaluate the pain degree before and after intervention; Retrospective Symptom Scale (RSS) was adopted to determine the improvement of symptoms.ResultThere were no significant differences in comparing the VAS score, real-time effect and post-treatment effect, and effective rate among different uterine positions (P>0.05). Electroacupuncture at Sanyinjiao (SP 6) can produce a real-time effect in releasing abdominal pain and relevant symptoms of dysmenorrhea in patients with anteversion of uterus, a less significant effect was shown in patients with retroposition of uterus, while no effect was shown in patients with uterus at middle position.ConclusionElectroacupuncture at Sanyinjiao possibly has a specific effect in releasing abdominal pain and relevant symptoms of dysmenorrhea at anteversion of uterus, and the uterine position may be related to the corresponding meridians and Zang-fu organs. The current statistical result indicates that there is no relation between the uterine position and the effect of Sanyinjiao, but this conclusion still needs proving by prospective randomized controlled clinicaltrials.
