Abstract

Levator ani muscles undergo significant stretching and micro-trauma at childbirth. The goal was to assess the neuromuscular integrity of this muscle group by means of magnetomyography and correlate with Brink score - a commonly used digital assessment of pelvic floor muscle strength. Methods: Non-invasive magnetomyography (MMG) data was collected on 22 pregnant women during rest and voluntary contraction of the pelvic-floor muscles (Kegels). The mean amplitude and power spectral density (PSD) of the Kegels were correlated to Brink pressure score. Results: The Brink's scores demonstrated medium correlations (≥0.3) with MMG amplitude and PSD with the average Kegel of medium intensity and rest. Data showed that the "resting state" of the pelvic floor is, in actuality, quite dynamic and may have implications for pelvic floor disorder propensity postpartum. Conclusion: These results confirm the ability of non-invasive magnetomyography to reliably capture pelvic floor contraction as these signals correlate with clinical measure. .

在评估盆底肌肉力量方面，非侵入性磁测图与布林克评分的比较。

肛提肌在分娩时会受到明显的拉伸和微小创伤。我们的目标是通过磁力造影术评估这组肌肉的神经肌肉完整性，并将其与布林克评分--一种常用的骨盆底肌肉力量数字评估方法--相关联。方法：我们收集了 22 名孕妇在休息和骨盆底肌肉（Kegels）自主收缩时的无创性磁力造影术（MMG）数据。结果：布林克评分与中等强度和静止时平均凯格尔运动的 MMG 振幅和 PSD 呈中等相关性（≥0.3）。数据显示，盆底的 "静息状态 "实际上是相当动态的，可能对产后盆底障碍的倾向有影响。结论：这些结果证实了无创磁测图能够可靠地捕捉盆底收缩，因为这些信号与临床测量结果相关。
