Abstract
Longitudinal cervical length changes differ significantly throughout gestation among singleton, twin, and triplet pregnancies. Cervical length measurements made in a standing position are comparable with those measured while supine, whereas cervical lengths measured during the Valsalva maneuver are significantly shorter than those made in either the supine or standing position.
