I didn't check whether the link mentioned goes into this, but I wanted to add that two 'tricks' I was taught as a doula were to have mom on hands & knees and partner use hands (or their own knees by standing behind her, if you can picture that) and apply a 'double-hip squeeze', or having her rock/circle her hips in this position or while standing. Also during labor you can create a larger space for a babe to turn anterior by lunging with the leg on the side where the back of baby needs to turn to (i.e. - baby's back is to the left, so stand and raise the right leg on a chair a lunge gently to really open that right hip. Now baby can swing round in that open space to face the other way.)
My sense is that rotation may not occur until during descent in labor, although all of that hands & knees rocking is definately worth it.
[ps. also helps to refuse non-necessary induction since a baby who is not ready to come out may not have moved into final position.]
