The action of squatting in the early postnatal period marginally increases pelvic dimensions

R J Lilford et al. Br J Obstet Gynaecol. 1989 Aug.

Abstract

X-ray pelvimetry was performed on 43 women in the squatting and erect positions within 1 week of delivery. The act of squatting increased the transverse and antero-posterior pelvic dimensions by 1%. The theoretical mechanisms by which posture may affect dimensions are discussed.
