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.

Conditions

Pelvic Floor Dyssynergia; Phonation Disorder

Study Design

• Observational Model Type: OTHER
• Study Time Perspective: CROSS_SECTIONAL

Study Groups

Twenty healthy female university students

They will be selected from the faculty of physical therapy ,Cairo university

phonation and respiratory tasks

Intervention Type: OTHER

Participants performed various tasks to evaluate pelvic floor muscle activity and displacement. These included a maximum voluntary contraction ("cutting off the flow of urine mid-stream"), a pelvic floor strain ("bearing down for a bowel movement"), and the Valsalva maneuver to clear the Eustachian tubes. Additionally, phonation and respiratory exercises were conducted, such as producing the "ah" sound at different pitches, open-mouth exhalation, coughing, and semi-occluded vocal tract (SOVT) exercises using a small coffee straw, commonly used in singing warm-ups to enhance vocal efficiency. Each task lasted 3 seconds, with 1-minute rest intervals to assess their impact on pelvic floor displacement
