Dynamics of Pelvic Floor Muscles With Different Phonation Patterns Among Female Students

Some pelvic floor physical therapists are beginning to experiment with using phonation and vocalization cues to elicit different pelvic floor movements . However, there is a significant gap in the literature about the coordination and movement between the pelvic floor and glottis during speech and phonation, and there is an urgent need to identify the voices accompanied by increasing pelvic floor tone and integrating them into pelvic floor strengthening programs and voices accompanied by lowering pelvic floor tone and integrating them into pelvic floor down-training programs. To date, there has been only one study describing pelvic floor displacement during vocalization tasks. So this study aims to investigate pelvic floor muscle displacement during respiratory and phonatory tasks using trans-abdominal ultrasound to assess respiratory and phonatory tasks that can relax or enhance pelvic floor tone and be integrated into clinical practice.
