Transperineal ultrasound imaging was used to record sagittal images of pelvic structures during involuntary coughing and sustained maximal voluntary contractions. Imaging data were analyzed to calculate displacements of pelvic floor landmarks associated with activation of the puborectalis, striated urethral sphincter, and bulbocavernosus muscles. Anatomical features of functional urethral length and the resting position of the ano\u2010rectal and urethra\u2010vesical junctions were calculated. A principal component analysis and multiple logistic regression were used to consider which combinations of variables best distinguish between men with and without incontinence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five principal components were identified that together explained 72.0% of the data. Two principal components that represented (i) striated urethral sphincter activation and (ii) bulbocavernosus and puborectalis muscle activation were significantly different between participants with and without incontinence. Together these components correctly identified 88.1% of incontinent men, with a specificity and sensitivity of 91.3% and 84.2%, respectively. Poor function of the bulbocavernosus and puborectalis muscles could be compensated by good striated urethral sphincter function, but the bulbocavernosus and puborectalis muscles had less potential to compensate for poor striated urethral sphincter function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Dynamic features of pelvic floor muscle activation, particularly shortening of the striated urethral sphincter during cough and voluntary contraction, are related to continence status after
