Methods: From October 2004 to October 2007 in prenatal care, 36 weeks of gestation until the movables, ultrasound and obstetrics examination confirmed by occipital posterior position, 200 children aged 21 to 35 years old were randomly divided into two groups , The observation group to take side prone position and thoracolumbar combined with posterior position correction pillow, the control group to take free position. Results: In the movable group, 89 cases were transferred to the anterior occipital position, 5 to the occipital transverse position, 6 posterior occiput posterior position and 6% In 46 cases, the posterior occiput posterior position and posterior occipital posterior position were 46%, the difference was statistically significant (P <0.01).
