Effect of the birthing position on its evolution from a biomechanical point of view

During vaginal delivery, several positions can be adopted by the mother to more comfortable and help labor process. The chosen are very influenced factors such as monitoring intervention during second stage of labor. However, there is limited evidence support most ideal birthing position. This work aims at contributing a better knowledge associated with widening pubic symphysis biomechanics flexible non-flexible sacrum that labor, well their resulting pathophysiological consequences. A validated computational model composed pelvic floor muscles attached bones, fetus head was used simulate deliveries. modified mimic two positions: one allows free movement coccyx in other which this restricted positions. also considered facilitate passage head. results obtained showed that, positions, where restricted, occur rotation 3.6° 6 mm symphysis. In contrast, move, 15.7° 3 mm, appearing beneficial for mother's pelvis, but slightly higher stresses were detected muscles. Globally, allow conclude different lead changes female space, so certain reduce risk obstructed development dysfunctions. More specifically, kneeling, standing, squatting sitting bone structure her pelvis they lower
