Application of Transperineal 3‐Dimensional Ultrasound in Evaluating Levator Ani Muscle Contraction During Female Pelvic Floor Rehabilitation

Transperineal 3-dimensional ultrasonography allows non-invasive and quantitative evaluation of pelvic floor anatomy. The strong correlations between dynamic parameters and the Oxford score demonstrate its ability to objectively assess pelvic floor muscle strength. This modality may therefore contribute to the objective characterization of pelvic floor muscle function and may inform future studies in postpartum pelvic floor rehabilitation.
