Brief Summary

This is a randomized controlled experimental study to determine the effect of maternal position on the progression of labour in deliveries in which the foetus is in the occiput posterior position. The study included 148 gravidas admitted to a private Istanbul hospital, who consented to participate. They were divided into intervention and control groups (n=72). The intervention group assumed a side-lying position on the occiput side for 20 minutes, a prostrate position for 15 minutes, then leaned towards the bed's head for 10 minutes (rest), followed by another 20-minute side-lying position. The control group received routine delivery care.

Intervention group

EXPERIMENTAL

The positioned group assumed a side-lying position on the occiput side for 20 minutes, a prostrate position for 15 minutes, then leaned towards the bed's head for 10 minutes (rest), followed by another 20-minute side-lying position.

Behavioral: Positioned group

Control group

NO INTERVENTION

The control group was followed up in the routine delivery room, and no positioning was done.

Interventions
