New imaging method for assessing pelvic floor biomechanics

Abstract

Translabial ultrasound can be used to measure strain, a component of pubovisceral muscle elasticity, and we have validated the technique against clinical assessment. Pubovisceral strain during contraction correlates positively with Oxford grade. Pubovisceral strain during Valsalva correlates negatively with resting tone grade. This new non-invasive ultrasound technique may be of value for assessing patients with pelvic floor dysfunction.
