Does the prevalence of levator ani muscle avulsion differ when assessed using tomographic ultrasound imaging at rest <i>vs</i> on maximum pelvic floor muscle contraction?

Abstract

Findings on transperineal TUI performed in women at rest and on contraction correlate reasonably well. However, given the trend towards an association with signs of pelvic floor dysfunction, diagnosis of LAM avulsion on contraction seems to be more reliable. Consistency in technique and interpretation should be maintained.
