A systematic review from Holland has concluded that acupuncture-type interventions (moxibustion, acupuncture, or electro-acupuncture) on Zhiyin BL 67 are effective in correcting breech presentation, compared with expectant management. Of 65 citations retrieved from various databases, six RCTs and three cohort studies fulfilled the reviewers’ inclusion criteria. In the RCTs the pooled proportion of breech presentations was 34% following treatment versus 66% in the control group. The pooled proportion in the cohort studies was 15% versus 36%. Including all studies, the proportion of breech presentations was 28% following treatment versus 56% for the control group.
