Hands and knees position and pelvic rocking exercise does not help babies to rotate from the posterior to the anterior position before birth. Kariminia and colleagues (p 490) randomised 2547 pregnant women to the exercise or to standard care during the last four weeks of pregnancy. They found no differences of persistent posterior fetal position, transverse arrest, mode of delivery, and duration of labour between groups.
