Rebozo and maternal postures to prevent persistent occiput posterior position of the fetal head: protocol for a randomised clinical trial 'the ReMaP-POPP RCT'.

introductionOcciput posterior position is the most common fetal malposition, complicating up to 35% of initial labours, and its persistence can lead to increased risks of adverse maternal and perinatal outcomes. The role of maternal postures, such as lateral recumbent and hands-and-knees, in promoting the anterior rotation of the fetal head has been investigated in several randomised trials in the last two decades, with mostly negative results. However, both methodological and study design limitations may have contributed to such findings. Recently, the use of forward-leaning inversion and side-lying release procedures and of the Rebozo technique has been implemented into clinical practice as a non-invasive alternative to promote the anterior rotation of the fetal head. Yet, neither intervention has been rigorously assessed in a controlled study. Our aim is to conduct a randomised controlled trial to assess whether a combination of forward-leaning inversion and side-lying release procedures and the Rebozo technique in a pre-specified sequence during the first stage of labour of women with a posterior fetus would favour its anterior rotation. METHODS AND ANALYSES: The ReMaP-POPP ( ETHICS AND DISSEMINATION: The study has been approved by the Lombardy Ethics Committee n.3 (n. 5499, 20 December 2024). Written informed consent will be obtained from all participants. Women will be free to decline participation or to withdraw at any time. Findings will be presented at scientific meetings and published in peer-reviewed scientific journals in the field of midwifery and obstetrics. Also, they will be disseminated to the public through outreach activities involving families and healthcare specialists. TRIAL REGISTRATION NUMBER: The study has been registered in the Clinical Trials database (NCT06887634).
