The Effects of Vocal Function Exercises on Aerodynamic Parameters for Children Receiving Voice Lessons

by Sayles, Claire Lindsey

Abstract (Summary)
The primary purpose of this investigation was to examine the effects of Vocal Function Exercises (VFEs) on the aerodynamic parameters of open quotient, speed quotient, maximum flow declination rate, and subglottal pressure in 8 subjects between the ages of 6 years 2 months and 8 years 11 months with an interest in singing. Results were compared to normative data. This study also evaluated the difference between the average weekly phonation times of the subjects’ Vocal Function Exercise #4 across 8 weeks of intervention. Each subject underwent aerodynamic assessment before and after the 8-week VFE intervention period. During the 8-week intervention period, each subject performed the VFEs twice a day. Results indicated significant difference between certain tasks of the aerodynamic measurements of open quotient, maximum flow declination rate, and subglottal pressure. A significant increase was found for the mean average weekly phonation times across the 8-week intervention period.
