Abstract Objective: To explore the clinical effective of Bionic Electrical Stimulation Therapy (BEST) for improving women uterus recovering after medical abortion. Methods: From January to December 2014, 179 unwanted pregnant women who performed medical abortion were randomized into three groups: BEST combined oral contraceptive(OC) group(n=60), OC only group(n=61) and control group(n=58). All women were followed up to two weeks after MA and to menstrual recovered. The evaluation index included clinical symptoms, hemoglbin(HB) and oucomes of ultrasonography. Results: The degree and duration of abdominal pain of women in BEST combined with OC group were the lowest in the tree group. Women in BEST combined with OC group and in OC group, whose vaginal bleeding volume was less , bleeding duration was shorter, and the menstrual recovery was quicker(P<0.05). Hemoglobin decreasing of women in BEST combined with OC group was less than that of women in OC group and control group (P<0.05). Based on ultrasonography, number of women with no residue in uterus cavity in BEST combined with OC group were higher than that of control group, and their endometrial were thicker than that of control group (P<0.05). Number of women with no residue in BEST combined with OC group was least among the three groups (P<0.05). Conclusion: The BEST combined with OR should decrease pain and improve uterus recovering for women after medical abortion. It is an advantage therapy with safety, non-invasive and no side effect, which is worthy of clinical promotion.
