It has also been shown that acupuncture plus moxibustion slows fetal heart rates while increasing fetal movement. Two recent studies of Italian patients produced conflicting results. In the first, involving 226 patients, there was cephalic presentation at delivery in 54% of women treated between 33 and 35 weeks with acupuncture and moxibustion, vs. 37% in the control group. The second was terminated prematurely because of poor compliance with treatment, but found no difference between moxibustion and control groups.
