A Chinese study has concluded that electroacupuncture (EA) at Sanyinjiao SP-6 is an effective way of decreasing labour pain. A total of 350 women in labour were randomised to either electroacupuncture at Sanyinjiao SP-6, sham electroacupuncture at Sanyinjiao SP-6 or a control group. Self-rated labour pain scores from women in the verum electroacupuncture group were significantly less than in the control group after 30 minutes of needle retention and at two and four hours after needle withdrawal. Other evaluated outcomes did not show significant differences among the three groups. (Effects of Sanyinjiao (SP6) with electroacupuncture on labour pain in women during labour.
