ABSTRACT
OBJECTIVE: The aim of the present workis to correlate the perceptual parameters grade, roughness and breathiness of the GRB scale with the contact quotient (CQ) obtained by electroglotography. MATERIAL AND METHOD: 70 samples of normal and pathological voices were analyzed by means of auditory-perceptual analysis and electroglotography. The perceptual analysis was carried out by two expert judges depending on the parameters grade, roughness and breathiness. The CQ values were obtained through the VoceVista System Version 3.3.7. RESULTS: The results show a strong correlation between CQ and breathiness (r = -0.869), whereas between grade of dysphonia and CQ (r = -0.567), and roughness and CQ (r = 0.643) the correlation is average. CONCLUSIONS: It is possible to establish relationships between the vibrational behavior of the vocal folds and the resulting phenomenon that we perceive auditively. The most relevant parameter in this respect was breathiness. The correlation between grade, roughness and CQ was weaker.

El sonar Doppler es una herramienta que permite captar lo que sucede durante la etapa faríngea de la deglución, siendo el sonido percibido y observado un reflejo parcial de la actividad motora que se desencadena. El presente trabajo indaga acerca de las posibilidades del sonar Doppler y su aplicación en la evaluación funcional de la deglución. Se desarrolla un diseño de investigación observacional y retrospectivo, bajo la metodología de revisión sistemática a partir de material bibliográfico, investigaciones y publicaciones de artículos de revistas en inglés, portugués y español, consultando las bases de datos PubMed, SciELO, EBSCO Host, Scopus, Springer, Cochrane, además de revistas especializadas en ASHA, MedLine, CEFAC y Redalyc. Aunque la fiabilidad y validez en el uso del sonar Doppler para la evaluación funcional de la etapa faríngea de la deglución no están aseguradas, podría llegar a brindar enorme ayuda en el diagnóstico de las aspiraciones y/o penetraciones durante el proceso deglutorio. Se insiste en una constante revisión de la metodología para la detección correcta de los sonidos de la deglución y su posterior análisis e interpretación clínica (AU)
Sonar Doppler is a tool that can capture what happens during the pharyngeal stage of swallowing, being the sound perceived and the noting a partial reflection of the motor activity that is triggered. This paper focuses on the possibilities of sonar Doppler and its application in functional assessment of swallowing. The design of this research is retrospective and observational, developed under the systematic review methodology, from bibliographical material, pieces of research and publications of journal articles in English, Portuguese and Spanish, taking the databases of PubMed, SciELO, EBSCO Host, Scopus, Springer, Cochrane, besides specialized magazines in ASHA, MedLine, CEFAC and Redalyc. Although the reliability and validity in the use of sonar Doppler for the functional evaluation of the pharyngeal stage of swallowing are uncertain, it could provide enormous help in diagnosing aspirations and/or penetrations during the swallowing process. We insist on a constant review of the methodology for the correct detection of sounds of swallowing and subsequent analysis and clinical interpretation (AU)

El presente trabajo constituye una revisión bibliográfica acerca de la efectividad de la terapia/entrenamiento funcional aplicada a docentes con alteraciones vocales funcionales. Se desarrolla un diseño de investigación observacional y retrospectivo, bajo la metodología de revisión sistemática, a partir de publicaciones de revistas en las bases de datos PubMed, SciELO, Scopus y Cochrane, así como en revistas especializadas como la de la American SpeechLanguage-Hearing Association (ASHA), Journal of Voice, CEFAC y Redalyc. La revisión del material evidencia resultados positivos para los distintos abordajes abarcados. En diversas proporciones, cada uno contribuye a mejorar la calidad vocal, sostener el equilibrio entre los componentes que construyen la emisión y prolongar la armonía que debe sustentar la voz.
This paper constitutes a bibliographic review on the effectiveness of therapeutic/training approaches applied in teachers with vocal alterations. Research has been designed in a retrospective and observational way, with a systemic review methodology based on publications from papers indexed in PubMed, SciELO, Scopus and Cochrane databases, as well as specialized journals such as American Speech-Language-Hearing Association (ASHA), Journal of Voice, CEFAC and Redalyc. The review of the material showed positive results for the different approaches. In varying proportions each one contributes to improve voice quality, hold the balance between the components that build the emission and prolong the harmony which should sustain the voice.
