Moxibustion was tested for version of a breech position in singleton pregnancies. The women were randomized in week 32 to either moxibustion on acupuncture point Bl 67 daily in 15-20 minutes or no moxibustion. In week 36-37 the fetal position was checked and external cephalic version was offered for those still in breech position. The randomization was stratified for primigravida and multiparae separately. The randomization was made with a random number even and odd numbers indicating moxibustion or not. The randomization result was hidden in a sealed, non-transparent envelope on the obstetrical department and drawn when the woman gave informed consent to the study.
