Graham (2014) Australia | To determine the feasibility of a multicentre RCT to investigate whether DR of the foetal head from OP position in the second stage of labour reduces the risk of OD | Pilot study | 1004 women consented. Randomised: 30; DR: 15 Sham procedure: 15 |
Le Ray (2007) France | To identify the risk factors for failure of MR in patients with OP or OT positions during labour and to study the caesarean rate in relation to the success of the rotation | Case-control study | MR performed on 796 women. After randomization: 79 successful MR, 68 failed MR |
