Background:
Lateral and posterior position of the fetal presenting parts may be associated with more painful, prolonged or obstructed labour and difficult delivery. It is possible that maternal posture may influence fetal position.
Objectives:
The objective of this review is to assess the effects of adopting a hands and knees maternal posture in late pregnancy when the presenting part of the fetus is in a lateral or posterior position.
Search Strategy:
We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register. Date of last search: February 1999.
Selection Criteria:
Randomised trials of hands and knees maternal posture compared to other postures.
Data Collection And Analysis:
Both reviewers assessed trial eligibility and quality.
Main Results:
One trial involving 100 women was included. Four different postures (four groups of 20 women) were combined for the comparison with the control group of 20 women. Lateral or posterior position of the presenting part of the fetus was less likely to persist following 10 minutes in the hands and knees position compared to a sitting position (relative risk 0.25, 95% confidence interval 0.17 to 0.37).
Reviewer'S Conclusions:
Hands and knees maternal posture for lateral or posterior fetal presentation appears to result in short term effects ion fetal position. No other perinatal or maternal outcomes were reported. There is not enough evidence to evaluate the effectiveness of a hands and knees maternal posture when the fetal presenting part is lateral or posterior, on clinically important outcomes.
