Objective: The purpose of this study was to compare the effect of childbirth delivery method on vaginal pressure and abdominal thickness during Valsalva maneuver.
Methods: Subjects were 30 female adults in their 20s and 30s. Subjects were divided into nulliparous, vaginal delivery and Cesarean delivery groups with 10 subjects in each group.
A digital perineometer was used to measure the vaginal contraction pressure during Valsalva. Ultrasound was used to measure the thickness of the abdominal muscles.
Valsalva maneuver was defined as the maximum straining effort with forced expiration against a closed glottis.
