Abstract/OtherAbstract:
OBJECTIVES: The primary purpose of the present study was to establish a preliminary adult normative database for 41 phonatory aerodynamic measures obtained with the KayPENTAX Phonatory Aerodynamic System (PAS) Model 6600 (KayPENTAX Corp, Lincoln Park, NJ). A second purpose was to examine the effect of age and gender on these measures.
DESIGN: Prospective data collection across groups.
METHOD: A sample of 157 normal speakers (68 males and 89 females) were divided into three age groups (18-39, 40-59, and 60+ years). The PAS protocols of vital capacity, maximum sustained phonation, comfortable sustained phonation, variation in sound pressure level, and voicing efficiency were used to collect 41 phonatory aerodynamic measures. Comfortable pitch and loudness levels were used with each protocol requiring phonation.
RESULTS: A statistically significant main effect of age was found for seven measures, and a statistically significant main effect of gender was found for five measures. The remaining 29 measures did not reach statistical significance; however, 13 of these had high observed power. The remaining 16 measures did not reach significance and had low observed power.
CONCLUSIONS: Because age- and gender-related changes were found for some measures, one must account for these two variables when assessing phonatory aerodynamics using the PAS Model 6600. The clinical implications of the findings for the assessment and treatment of individuals with voice disorders using the PAS Model 6600 are discussed.
