Distribution of the pelvic floor muscle fibers: Comparison between magnetic resonance tractography and finite element method representation

The pelvic modeling usually starts with the use of geometric models from MRI to posterior numerical simulations (d´Aulignac et al. 2005). These allow us to simulate contraction or valsalva maneuver, which illustrate the two most frequent pelvic floor muscles functions: the active and conscious voluntary muscle contractions and the involuntary/passive muscle contraction to counteract the increase in intra-abdominal pressure during coughing, weight lift or jumping exercises, vaginal delivery or chronic bowel obstruction.
