Does vaginal closure force differ in the supine and standing positions?

Article Abstract:

The study aims to quantify resting vaginal closure force (VCF(super REST)), maximum vaginal closure force (VCF(super REST)), and augmentation of vagina closure force augmentation (VCF(super REST)). It concluded that with change the posture, vaginal closure force increases because of higher intra-abdominal pressure and greater resistance in the pelvic floor muscles.

Pudendal nerve stretch during vaginal birth: A 3D computer simulation

Article Abstract:

The study aims to determine the increase in pudendal nerve branch lengths using a 3D computer model of vaginal delivery. The inferior rectal branch exhibited the maximum strain, 35%, and this strain varied by 15% from the scenario with the least perineal descent to that with the most perineal descent.

Can women without visible pubococcygeal muscle in MR images still increase urethral closure pressures?

Article Abstract:

The ability to increase maximum urethral closure pressure (MUCP) with pelvic muscle contraction in women without pubococcygeal muscle (PCM) is examined. Results reveal that there was a 50 percent decline in the ability to increase urethral pressure in women with loss of pubococcyeus.
