Efectividad de los métodos de evaluación fonético acústico para el diagnóstico de la disfonía en adultos y adultos mayores.

Abstract

INTRODUCTION: Dysphonia is a voice disorder that occurs when the quality, tone and volume of this difference, its evaluation can be subjective and objective, highlighting within the objective procedures, two recently developed methods to quantify the severity of the dysphonia, the smoothed cepstral prominence measure (CPPS) and the acoustic voice quality index (AVQI); the objective of this study is to determine the diagnostic precision (AVQI) in relation to the (CPPS) in the evaluation of the sustained and continuous voice METHODS: a systematic systematic review was performed through a literature search and statistical analysis of the information RESULTS: found the test (AVQI) proves to be more specific but less sensitive than the standard reference test. The (AVQI) has greater diagnostic capacity with Odds Ratio values of 42.55 in relation to 22.74 of the test (CPPS). ANALYSIS AND DISCUSSION: the heterogeneity of the evidence found and the diagnostic precision of the tests under study, allows determine that the AVQI is more heterogeneous than the (CPSS), however it is more precise in the evaluation and diagnosis of the voice CONCLUSIONS: The (AVQI) demonstrated the most robust acoustic measure for the evaluation and diagnosis of the severity of dysphonia since it encompasses six acoustic markers that globally measure sustained and continuous voice quality.
