Temporal characteristics of velopharyngeal function in children

Area of Science:

• Speech-language pathology
• Aerodynamics
• Pediatric audiology

Background:

• Velopharyngeal closure is crucial for speech production.
• Aerodynamic analysis provides insights into velopharyngeal function.
• Understanding temporal aspects of velopharyngeal closure in children is essential.

Purpose of the Study:

• To evaluate the performance of children with normal speech on temporal aspects of aerodynamic tasks.
• To examine aerodynamic features related to velopharyngeal function during speech tasks.
• To establish normative data for velopharyngeal closure in children.

Main Methods:

• Descriptive evaluation of aerodynamic features during speech.
• Participants included 24 children aged 3-12 years with normal speech and velopharyngeal function.
• Measures included peak intraoral air pressure, peak nasal airflow, and temporal parameters.

Main Results:

• Aerodynamic procedures were reliable for assessing velopharyngeal closure in children.
• A trend of decreased temporal parameter duration with increasing age was observed.
• Children's temporal values were comparable to those of normal-speaking adults.

Conclusions:

• This study provides preliminary data for comparing velopharyngeal closure temporal features in children.
• Findings can aid in the aerodynamic evaluation of children with impaired velopharyngeal function.
• Normative data on temporal aspects of velopharyngeal closure are valuable for clinical assessment.
