一种新的理论声称，骨盆底肌肉（PFM）可以通过腹横肌（TrA）进行训练。本研究的目的是使用4D会阴超声比较PFM和TrA收缩指令对提肌裂孔收缩的影响。13名患有盆腔器官脱垂的妇女参加了这项研究。采用站立位会阴超声检查来评估提肌裂孔的收缩情况。离线进行分析，测量最小裂孔尺寸的轴向平面。在PFM期间，所有食管裂孔尺寸的减小均显著大于TrA收缩。在PFM收缩期间，所有患者的提肌裂孔面积均减小（平均减小24.0%;范围6.1-49.2%）。在两名患者中，有一个增加的提肌裂孔面积在TrA收缩。PFM收缩的指导比TrA收缩更有效。
A new theory claims that the pelvic floor muscles (PFM) can be trained via the transversus abdominis (TrA). The aim of the present study was to compare the effect of instruction of PFM and TrA contraction on constriction of the levator hiatus, using 4D perineal ultrasonography. Thirteen women with pelvic organ prolapse participated in the study. Perineal ultrasound in standing position was used to assess constriction of the levator hiatus. Analyses were conducted off-line with measurements in the axial plane of minimal hiatal dimensions. The reduction of all the hiatal dimensions was significantly greater during PFM than TrA contraction. All patients had a reduction of the levator hiatus area during PFM contraction (mean reduction 24.0%; range 6.1-49.2%). In two patients, there was an increase of the levator hiatus area during TrA contraction. Instruction of PFM contraction is more effective than TrA contraction.
