Pompoir is a technique poorly studied in the literature that claims to improve pelvic floor strength and coordination. This study aims to investigate the pelvic floor muscles' coordination throughout the vaginal canal among Pompoir practitioners and non-practitioners by describing a high resolution map of pressure distribution.
This cross-sectional, study included 40 healthy women in two groups: control and Pompoir. While these women performed both sustained and "waveform" pelvic floor muscle contractions, the spatiotemporal pressure distribution in their vaginal canals was evaluated by a non-deformable probe fully instrumented with a 10×10 matrix of capacitive transducers.
Pompoir group was able to sustain the pressure levels achieved for a longer period (40% longer, moderate effect, P=0.04). During the "waveform" contraction task, Pompoir group achieved lower, earlier peak pressures (moderate effect, P=0.05) and decreased rates of contraction (small effect, P=0.04) and relaxation (large effect, P=0.01). During both tasks, Pompoir group had smaller relative contributions by the mid-region and the anteroposterior planes and greater contributions by the caudal and cranial regions and the latero-lateral planes.
Results suggest that specific coordination training of the pelvic floor muscles alters the pressure distribution profile, promoting a more-symmetric distribution of pressure throughout the vaginal canal. Therefore, this study suggests that pelvic floor muscles can be trained to a degree beyond strengthening by focusing on coordination, which results in changes in symmetry of the spatiotemporal pressure distribution in the vaginal canal.
“蓬波尔运动”是一种在文献中研究较少的技术，据称可增强盆底力量和协调性。本研究旨在通过描绘压力分布的高分辨率图谱，调查“蓬波尔运动”练习者和非练习者整个阴道管内盆底肌肉的协调性。
这项横断面研究纳入了40名健康女性，分为两组：对照组和“蓬波尔运动”组。当这些女性进行持续性和“波形”盆底肌肉收缩时, 通过一个完全配备有10×10电容式换能器矩阵的不可变形探头，评估她们阴道管内的时空压力分布。
“蓬波尔运动”组能够将达到的压力水平维持更长时间（长40%，中度效应，P = 0.04）。在“波形”收缩任务中，“蓬波尔运动”组达到的峰值压力更低、更早（中度效应，P = 0.05），收缩率（小效应，P = 0.04）和松弛率（大效应，P = 0.01）降低。在两项任务中，“蓬波尔运动”组中部区域和前后平面的相对贡献较小，而尾侧和头侧区域以及外侧平面的贡献较大。
结果表明，盆底肌肉的特定协调性训练会改变压力分布模式，促进整个阴道管内压力更对称地分布。因此，本研究表明，通过专注于协调性，盆底肌肉可以训练到超出增强力量的程度，这会导致阴道管内时空压力分布对称性的变化。
