Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The goal of this clinical trial is to assess whether a combination of forward-leaning inversion and side-lying release procedures and Rebozo technique in a pre-specified sequence during the first stage of labor among women with a posterior fetus would favor anterior rotation. The main questions it aims to answer is:
• What is the probability of persistent occiput posterior position of the fetal head three hours and thirty minutes after randomization, diagnosed by sonography? Researchers will compare the intervention group, which received a sequence of forward-leaning inversion (FLI), side-lying release procedures (SLR), and the Rebozo technique (lasting 90-105 minutes), to the control group, which received standard care (free maternal postures), to assess whether the specific combination of interventions in the experimental group reduces the probability of the fetal head remaining in the occiput posterior position.
Participants in the intervention group will undergo a combination of forward-leaning inversion, side-lying release procedures, and the Rebozo technique, administered in a pre-determined sequence. In contrast, participants in the control group will receive standard care (free maternal postures).

Rebozo and Maternal Procedures
Intervention Type
OTHER
Combination of FLI and side-lying release SLR and Rebozo technique in a pre-specified order:
1\) FLI for 30 seconds repeated for 3 subconsequent contractions; 2) SLR for 30 seconds repeated for 3 consequent contractions; 3) Rest with free maternal postures for 15 minutes; 4) 15 minutes of Rebozo on maternal pelvis (women on hands and knees); 5) Rest with free maternal postures for 15 minutes; 6) 15 minutes of Rebozo on the side of the fetal spine (supine women).
Duration of the intervention ranges between 90 and 105 minutes. The intervention will start within thirty minutes after randomization; it can be interrupted at any time if needed. It will be considered performed when the proposed sequence is completed. After completion of the sequence, women will be allowed to move freely and adopt different postures. No FLI or SLR procedures or the Rebozo technique will be further allowed until sonographic assessment of the fetal head is performed at 3 hour and thirty after randomization
Control group
Standard of care, including upright, semi-recumbent, lateral recumbent, and hands-and-knees position.
