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

Not yet recruiting

• Conditions: Pelvic Floor Dyssynergia; Phonation Disorder

• Registration Number: NCT06716268
• Lead Sponsor: Cairo University

Brief Summary

The purpose of the study is to know if there is relation between the dynamics of pelvic floor muscles and different phonation pattern.

Detailed Description

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.

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Assessment of pelvic floor muscle displacement	1 month	Pelvic floor displacement during phonation will be assessed using trans-abdominal ultrasound with a 3.5-MHz transducer. Posterior bladder wall displacement will be measured in the sagittal plane with standardized markers at rest and maximal distortion. A bladder filling protocol will ensure imaging clarity. Participants will perform pelvic floor tasks (e.g., contraction, strain, Valsalva) and phonation/respiratory exercises (e.g., "ah" sounds, coughing, SOVT exercises). Tasks will last 3 seconds, be repeated thrice, and baseline and end measurements will be recorded.

Secondary Outcome Measures

Name	Time	Method
Voice pitch classification	1 month	the females' voice pitch will be classified by having them read "The North Wind and the Sun" three times consecutively in a quiet room, using a Samsung Note 20 mobile phone application for recording. The microphone is placed 30 centimeters from their mouths. The application measures average, median, highest (95th percentile), and lowest (95th percentile) frequencies in Hz to provide a comprehensive analysis of voice pitch and volume, aiding in assessing voice quality and potential disorders.
