ABSTRACT
Objective.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 (MMG) and correlate with Brink score-a commonly used digital assessment of pelvic floor muscle strength.Approach.Non-invasive 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.Main Results.The modified Brink pressure score 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.Significance.These results confirm the ability of non-invasive MMG to reliably capture pelvic floor contraction as these signals correlate with clinical measure.
