We hypothesize that the holistic and multiplanar depiction of pelvic floor structures by dynamic MRI is of particular value in rendering information about the extent of functional changes that can lead to pelvic floor dysfunction.
134 women were prospectively included for assessment of their pelvic floor function.
Study groups differed significantly in the direction of their force-displacement-vectors. A shift from ventral to dorsal is present depending on parity, mode of delivery and age. Maternal age and body height correlated to the force-displacement-vector, whereas maternal weight did not. Pressing direction proved to be dependent on the inclination of the pelvis and the aperture of the levator hiatus while remaining independent from the aperture of the abdominal wall.
Biomechanical data interpretation uncovered the pathogenetic relevance of progressive retroflection of the force-displacement-vector. This is responsible for the onset of a vicious cycle of trauma-related force deflection perpetuating pelvic floor traumatization.
我们假设，通过动态 MRI 对盆底结构进行整体和多层面的描述，对于提供有关可能导致盆底功能障碍的功能变化程度的信息具有特殊价值。
前瞻性纳入 134 名女性，评估其盆底功能。
研究组在力-位移矢量的方向上存在显著差异。根据产次、分娩方式和年龄的不同，存在从腹侧向背侧的移位。产妇年龄和身高与力-位移矢量相关，而产妇体重则不相关。按压方向取决于骨盆的倾斜度和提肌裂孔的开口，而与腹壁的开口无关。
生物力学数据分析揭示了力-位移矢量进行性后反的发病相关性。这是导致与创伤相关的力偏折的恶性循环开始的原因，这种偏折持续使盆底受到创伤。
