Voz, monotonia e autonomia no ambiente de trabalho de professores / Voice, monotony, and autonomy in teachers' work setting / Voz, monotonía y autonomía en el entorno laboral docente

Introdução: a relação entre voz e trabalho é objeto de estudo constante. Ainda não há investigação sobre a relação de monotonia e autonomia com queixas vocais. Objetivo: investigar a relação entre a monotonia e a autonomia no ambiente de trabalho com o surgimento de queixas vocais entre professores. Método: estudo exploratório, qualitativo e descritivo, realizado a partir de grupo focal considerando o ineditismo da temática do estudo. Dez professores triados em estudo anterior com suspeita de distúrbio de voz pelo Índice de Triagem de Distúrbio de Voz, que indicaram percepção de monotonia e falta de autonomia no ambiente de trabalho por meio do instrumento Condições de Produção Vocal de Professores foram convidados a participar. Sete professores aceitaram e foram conduzidos dois grupos focais. Perguntas disparadoras sobre monotonia e autonomia no ambiente de trabalho foram feitas. Após análise de conteúdo, foram criadas quatro categorias principais e subcategorias de análise. Resultados: os participantes debateram questões relacionadas à quebra de expectativas sobre o trabalho, frustrações, rotina e desafios diários. Considerações sobre a voz estavam relacionadas ao uso repetitivo e por longos períodos e ambiente com acústica desfavorável. Queixas como rouquidão e baixa projeção vocal foram citadas. Conclusão: monotonia no ambiente de trabalho foi percebida como algo repetitivo e as relações com o surgimento de queixas vocais podem estar relacionadas a situações de uso da voz de forma intensa e constante. A falta de autonomia parece ocasionar a monotonia e, consequentemente, desmotivação, frustração com a carreira e adoecimento, dentre eles, o distúrbio de voz. (AU)

Introduction: the relationship between voice and work is the subject of constant study. There is still no investigation into the relationship between monotony and autonomy and vocal complaints. Objective:to investigate the relationship between monotony and autonomy in the workplace with the emergence of vocal complaints among teachers. Method: exploratory, qualitative and descriptive study, carried out through a focus group considering the novelty of the study theme. Ten teachers screened in a previous study with suspected voice disorders using the Voice Disorder Screening Index, who indicated a perception of monotony and lack of autonomy in the work environment using the Teacher Vocal Production Conditions instrument were invited to participate. Seven teachers accepted and two focus groups were conducted. Triggering questions about monotony and autonomy in the workplace were asked. After content analysis, four main categories and subcategories of analysis were created. Results: participants discussed issues related to broken expectations about work, frustrations, routine and daily challenges. Considerations about the voice were related to repetitive use for long periods and an environment with unfavorable acoustics. Complaints such as hoarseness and low vocal projection were cited. Conclusion: monotony in the work environment was perceived as something repetitive and the relationship with the emergence of vocal complaints may be related to situations of intense and constant use of the voice. The lack of autonomy seems to cause monotony and, consequently, demotivation, frustration with one's career and illness, including voice disorders. (AU)

Introducción: la relación entre voz y trabajo es objeto de constante estudio. Todavía no se ha investigado la relación entre monotonía, autonomía y quejas vocales. Objetivo: investigar la relación entre monotonía y autonomía en el lugar de trabajo con la aparición de quejas vocales entre docentes. Método: estudio exploratorio, cualitativo y descriptivo, realizado a través de un grupo focal considerando la novedad del tema de estudio. Se invitó a participar a diez docentes evaluados en un estudio previo con sospecha de trastornos de la voz mediante el Voice Disorder Screening Index, que indicaron una percepción de monotonía y falta de autonomía en el ambiente de trabajo utilizando el instrumento Teacher Vocal Production Conditions. Siete profesores aceptaron y se realizaron dos grupos focales. Se formularon preguntas desencadenantes sobre la monotonía y la autonomía en el lugar de trabajo. Luego del análisis de contenido, se crearon cuatro categorías y subcategorías principales de análisis. Resultados:los participantes discutieron cuestiones relacionadas con expectativas rotas sobre el trabajo, frustraciones, rutina y desafíos diarios. Las consideraciones sobre la voz estuvieron relacionadas con el uso repetitivo por períodos prolongados y un ambiente con acústica desfavorable. Se citaron quejas como ronquera y baja proyección vocal. Conclusión: la monotonía en el ambiente laboral fue percibida como algo repetitivo y la relación con la aparición de quejas vocales puede estar relacionada con situaciones de uso intenso y constante de la voz. La falta de autonomía parece provocar monotonía y, en consecuencia, desmotivación, frustración con la propia carrera y enfermedades, incluidos trastornos de la voz. (AU)

Voice Disorder, Job Stress, and COVID-19 in Teachers: Impacts in Times of Pandemic

Introduction: The conditions of teachers' work during the COVID-19 pandemic affected teachers' lives regarding voice disorder and stress, even in emergency remote classroom situation. Objective: To analyze the relationship between the presence of voice disorder, job stress, and COVID-19 in teachers when in emergency remote classroom teaching situation at the time of the pandemic. Method: This is a primary, exploratory, observational cross-sectional study with the use of survey forwarded online during the period of emergency classes after the arrival of COVID-19 pandemic in Brazil. The teachers answered the sociodemographic questions about the presence of COVID-19 and the following instruments: Condition of Vocal Production-Teacher [Condição de Produção Vocal - Professor (CPV-P)], Screening Index for Voice Disorder (SIVD), and Job Stress Scale (JSS). Results: Of the 118 teachers analyzed, 94.1% were female; the average age was 44 years. The SIVD recorded the presence of voice disorder in 66.9% of the participants. Regarding the JSS, which are the findings related to stress at work in the demand domain, the teachers showed high levels, a fact which presupposes the existence of pressure of psychological nature to perform their work. Conclusion: The teachers self-reported the presence of voice disorder even in remote class situation, on the occasion of COVID-19, which were more common in older teachers. When comparing the presence of voice disorders, coronavirus symptoms, and stress domains in relation to demand, control, and social support, there was no significance. It is hoped that this study will help to reflect on the need to improve teachers' working conditions, strengthening work-related voice disorder actions and guiding actions for vocal care and well-being.

Introducción: Las condiciones de trabajo de los profesores durante la pandemia de COVID-19 afectaron sus vidas en lo que respecta al trastorno de la voz y el estrés, incluso en situaciones de emergencia en aulas remotas. Objetivo: Analizar la relación entre la presencia de trastorno de la voz, estrés laboral y COVID-19 en profesores cuando se encontraban en situación de emergencia de enseñanza en aulas remotas en la época de la pandemia. Método: Se trata de un estudio primario, exploratorio, observacional de tipo transversal, con el uso de encuesta remitida online durante el periodo de clases de emergencia tras la llegada de la pandemia de COVID-19 en Brasil. Los profesores respondieron a las preguntas sociodemográficas sobre la presencia de COVID-19 y a los siguientes instrumentos: Condición de Producción Vocal-Profesor (CPV-P), Índice de Detección de los Trastornos de la Voz (SIVD) y Escala de Estrés Laboral (JSS). Resultados: De los 118 profesores analizados, el 94,1% eran mujeres; la mediana de edad era de 44 años. El (SIVD) registró la presencia de trastorno de la voz en el 66,9% de los participantes. En cuanto a la JSS, que son los hallazgos relacionados con el estrés laboral en el dominio de la demanda, los profesores mostraron niveles elevados, hecho que presupone la existencia de presiones de naturaleza psicológica para realizar su trabajo. Conclusión: Los profesores autoinformaron de la presencia de trastornos de la voz incluso en situación de clase a distancia, con ocasión del COVID-19, que fueron más frecuentes en los profesores de más edad. Al comparar la presencia de trastornos de la voz, los síntomas del coronavirus y los dominios de estrés en relación con la demanda, el control y el apoyo social, no hubo resultados significativos. Se espera que este estudio ayude a reflexionar sobre la necesidad de mejorar las condiciones de trabajo de los docentes, fortaleciendo las acciones de Trastorno de la voz relacionado con el trabajo (WRVD) y orientando acciones para el cuidado y bienestar vocal.

Vocal Load of University Professors: Preliminary Results

Purpose: To describe the acoustic characteristics of a classroom, voice quality, fatigue, and vocal load of university professors. Methods: Exploratory, observational, longitudinal, and descriptive study with a single group of participants, including vocal monitoring data over two weeks. Acoustic characterization of the classroom, perceptual-auditory evaluation, and acoustic analysis of voice samples were conducted before and after classes. Vocal dosimetry was performed during classes, and the Vocal Fatigue Index (VFI) was assessed at the beginning of each week. Descriptive analysis of the findings was conducted, and randomization test was performed to verify the internal reliability of the judge. Results: All participants reported speaking loudly in the classroom, with the majority reporting vocal changes in the past six months, and only one participant reported a current vocal change. The classroom had acoustical measures and estimations that deviated from established standards. The professors used high vocal intensities during classes. After the classes, an increase in the absolute values of the aggregated data for CAPE-V, jitter, and fundamental frequency was found, varying within the range of normality. Furthermore, there was an observed increase in both post-lesson intensity and VFI when comparing the two-week period. Conclusions: Vocal intensities and VFI were possibly impacted by the acoustics of the classroom. The increase in average VFI between the weeks may be attributed to a cumulative fatigue sensation. Further research with a larger number of participants and in acoustically conditioned classrooms is suggested in order to evaluate collective intervention proposals aimed at reducing the vocal load on teachers.

Objetivo: Describir las características acústicas, calidad vocal, fatiga y carga vocal de profesores universitarios. Métodos: Estudio exploratorio, observacional, longitudinal, descriptivo con un solo grupo de participantes y datos de monitoreo vocal durante dos semanas. Se realizó caracterización acústica de la sala, evaluación auditiva-perceptiva y acústica de muestras de voz antes y después de las clases. Se realizó dosimetría vocal durante las clases y se verificó el Índice de Fatiga Vocal (IFV) en dos semanas. Se realizó un análisis descriptivo de los hallazgos y una prueba de aleatorización para verificar la confiabilidad interna del juez. Resultados: Todos los participantes informaron hablar en voz alta en clase, la mayoría informó cambios vocales en los últimos seis meses y solo uno informó cambios vocales actuales. La sala presentó mediciones y estimaciones acústicas fuera de las normas establecidas. Los profesores utilizaron intensidades vocales altas durante las clases. Hubo un aumento en los valores absolutos de los datos agrupados para CAPE-V, jitter y frecuencia fundamental, variando dentro de los límites normales, después de las clases. La intensidad después de las clases y el IFV, en la comparación entre las dos semanas, mostraron un aumento. Conclusiones: La dosis vocal y el IFV posiblemente se vieron afectados por la acústica del aula. El aumento del IFV medio entre semanas pudo deberse a la sensación de cansancio acumulada. Se sugieren nuevas investigaciones con un mayor número de participantes y que se realicen en la sala acondicionada acústicamente para evaluar propuestas de intervención colectiva, con el objetivo de reducir la carga vocal de los docentes.

Evidência de validade baseada nos processos de resposta de um protocolo de análise espectrográfica da voz / Evidence of response process validity of a spectrographic voice analysis protocol

RESUMO Objetivo desenvolver a etapa de validade baseada nos processos de resposta do Protocolo de Análise Espectrográfica da Voz (PAEV). Métodos foram recrutados dez fonoaudiólogos e dez alunos de graduação em Fonoaudiologia, que aplicaram o PAEV em dez espectrogramas, realizaram o julgamento dos itens do PAEV e participaram de uma entrevista cognitiva. A partir das respostas, o PAEV foi reanalisado para reformulação ou para exclusão de itens. Utilizou-se o teste Qui-Quadrado e os valores de acurácia para análise das respostas dos questionários, assim como análise qualitativa dos dados da entrevista cognitiva. Resultados os participantes obtiveram acurácia maior que 70% na maioria dos itens do PAE. Apenas sete itens alcançaram acurácia menor ou igual a 70%. Houve diferença entre as respostas de presença versus ausência de dificuldade na identificação dos itens no espectrograma. A maioria dos participantes não teve dificuldade na identificação dos itens do PAEV. Na entrevista cognitiva, apenas seis itens não obtiveram correta identificação da intenção, conforme verificado na análise qualitativa. Além disso, os participantes sugeriram exclusão de cinco itens. Conclusão após a etapa de validação baseada nos processos de resposta, o PAEV foi reformulado. Sete itens foram excluídos e dois itens foram reformulados. Dessa forma, a versão final do PAEV após essa etapa foi reduzida de 25 para 18 itens, distribuídos nos cinco domínios.

ABSTRACT Purpose To develop the validity step based on the response processes of the Spectrographic Analysis Protocol (SAP). Methods 10 speech therapists and 10 undergraduate students of the Speech Therapy course were recruited, who applied the SAP in 10 spectrograms, performed the evaluation of the PAE items, and participated in a cognitive interview (CI). The SAP was reanalyzed to reformulate or exclude items based on the responses. The chi-square test and the accuracy values were used to analyze the answers to the questionnaires and qualitative analysis of the CI data. Results the participants achieved accuracy > 70% in most items of the SAP. Only seven items achieved accuracy ≤ 70%. There was a difference between presence vs. absence of difficulty in identifying items in the spectrogram. Most participants had no problem identifying the SAP items. In the CI, only six items did not correctly identify the intention, verified in the qualitative analysis. In addition, participants suggested excluding five items. Conclusion After the validation step based on the response processes, the SAP is reformulated. Seven items were deleted, and two items were reformulated. Thus, the final version of the SAP after this stage was reduced from 25 to 18 items, distributed in the five domains.

Distúrbio de Voz Relacionado ao Trabalho: um olhar sobre o passado, o presente e o futuro / Work-Related Voice Disorder: a look at the past, present, and future

Resumo Introdução: o Distúrbio de Voz Relacionado ao Trabalho (DVRT) é um agravo de elevada prevalência, especialmente em professores. Em 2018, o Ministério da Saúde (MS) publicou o Protocolo DVRT, visando orientar sua identificação e notificação, de modo a subsidiar ações de vigilância sobre seus determinantes. Objetivo: sintetizar história, resultados de debates e reflexões acerca do DVRT no Brasil, desafios enfrentados e caminhos futuros para a formalização do seu reconhecimento. Método: ensaio teórico, realizado a partir de revisão de literatura, documentos e registros de participação dos atores sociais no processo de reconhecimento do DVRT. Resultados: a busca do reconhecimento do DVRT percorreu uma trajetória não linear, destacando-se três fases: elaboração de protocolos e formalização preliminar do DVRT; internacionalização das discussões; e inclusão do DVRT na nova lista de doenças relacionada ao trabalho do MS, seguida de revogação e repristinação. Conclusão: o processo de busca de reconhecimento do DVRT se transformou em um "imbróglio político-social", desdobrando-se em iniciativas do Poder Legislativo e do Conselho Nacional de Saúde e no reconhecimento nos estados da Bahia e do Espírito Santo. Desafios surgiram com as mudanças no mundo do trabalho, implementação de linhas de cuidado e capacitação profissional para o manejo do DVRT.

Abstract Introduction: Work-Related Voice Disorder (WRVD) is a highly prevalent condition, especially among teachers. In 2018, the Brazilian Ministry of Health (BMH) issued the WRVD Protocol to its identification and reporting as a means to subsidize health surveillance actions. Objective: to summarize the history, debate outcomes, challenges, and reflections about WRVD in Brazil. Methods: theoretical essay based on a literature review, documents, and records of social actors' involvement in the WRVD recognition process. Results: WRVD recognition followed a cumbersome trajectory comprising three phases: Protocol design and initial WRVD recognition; Improvement of exchanges with international communities; WRVD classification as a work-related disease (WRD), decision that was later repealed and then repristinated. Conclusion: WRVD recognition process unfolded into a "sociopolitical imbroglio," prompting initiatives by the Legislative Branch and the Brazilian National Health Council, and its recognition by the Bahia and Espirito Santo states. Challenges arose following changes in work, implementation of healthcare paths, and professional training for managing WRVD.

Medidas espectrais e cepstrais em mulheres com disfonia comportamental / Spectral and cepstral measurements in women with behavioral dysphonia

RESUMO Objetivo Investigar se existem diferenças nas medidas acústicas cepstrais e espectrais entre mulheres com disfonia comportamental com e sem lesão laríngea, bem como verificar se existe correlação entre tais medidas e o julgamento perceptivo-auditivo da qualidade vocal. Método Participaram 78 mulheres com disfonia comportamental sem lesão laríngea (DCSL) e 68 com disfonia comportamental com lesão laríngea (nódulos vocais) (DCCL). Foram extraídas as medidas CPP (cepstral peak prominence), CPPS (cepstral peak prominence smoothed), declínio espectral e H1-H2 (diferença entre a amplitude do primeiro e do segundo harmônico), assim como o julgamento perceptivo-auditivo (JPA) do grau geral de desvio vocal (GG), graus de rugosidade (GR), de soprosidade (GS) e de tensão (GT). Resultados Mulheres com DCCL apresentaram maiores valores de H1-H2 e menores valores no CPP e CPPS, em relação às mulheres com DCSL. As vozes mais desviadas apresentaram menores valores do CPP e CPPS. As vozes soprosas apresentaram menores valores de CPP e CPPS, assim como maior valor de H1-H2 em relação às vozes rugosas. Houve correlação negativa fraca entre o CPP e o GR, negativa moderada com o GG e negativa forte com o GS. O CPPS apresentou correlação negativa moderada com o GG, GR e GS. A medida H1-H2 apresentou correlação positiva fraca com o GS. Houve correlação positiva fraca entre o declínio espectral e o GT. Conclusão As medidas acústicas H1-H2, CPP e CPPS apresentam diferenças entre mulheres com DCSL e DCCL. Além disso, há correlação entre as medidas cepstrais e espectrais e os diferentes parâmetros do JPA.

ABSTRACT Purpose To investigate whether there are differences in cepstral and spectral acoustic measures between women with behavioral dysphonia with and without laryngeal lesions and verify whether there is a correlation between such measures and the auditory-perceptual evaluation of voice quality. Methods The sample comprised 78 women with behavioral dysphonia without laryngeal lesions (BDWOL) and 68 with behavioral dysphonia with laryngeal lesions (vocal nodules) (BDWL). Cepstral peak prominence (CPP), cepstral peak prominence-smoothed (CPPS), spectral decrease, and H1-H2 (difference between the amplitude of the first and second harmonics) were extracted. They were submitted to the auditory-perceptual evaluation (APE) of the grade of hoarseness (GH), roughness (RO), breathiness (BR), and strain (ST). Results BDWL women had higher H1-H2 values and lower CPP and CPPS values than BDWOL women. More deviant voices had lower CPP and CPPS values. Breathy voices had lower CPP and CPPS values and higher H1-H2 values than rough ones. There was a weak negative correlation between CPP and RO, a moderate negative correlation with GH, and a strong negative correlation with BR. CPPS had a moderate negative correlation with GH, RO, and BR. H1-H2 had a weak positive correlation with BR. There was a weak positive correlation between spectral decrease and ST. Conclusion H1-H2, CPP, and CPPS were different between BDWOL and BDWL women. Furthermore, cepstral and spectral measures were correlated with the different APE parameters.

Autopercepção do Impacto Imediato na Voz de Cantores Gospel após uma Apresentação de uma hora / Self-perception of the Immediate Impact on the Voice of Gospel Singers after a one-hour Presentation

RESUMO Objetivo Investigar o impacto imediato na voz de cantores gospel com e sem queixa vocal após uma apresentação individual de uma hora. Método Aplicação de um questionário online que abordou os seguintes aspectos: 1 - Dados sociodemográficos; 2 - Autoavaliação da habilidade de cantar pelo protocolo Evaluation of the Ability to Sing Easily (EASE-BR); 3 - Autoavaliação de sintomas de fadiga vocal pelo Índice de Fadiga Vocal (IFV); e 4 - Autoavaliação da desvantagem vocal pelo protocolo Índice de Desvantagem Vocal 10 (IDV-10). Os participantes foram divididos em dois grupos: Grupo Com Queixa (CQ) e Grupo Sem Queixa (SQ) com base no escore total do IDV-10. Os dados passaram por análise estatística descritiva e inferencial considerando o nível de significância de 5%. Resultados Participaram 43 cantores gospel com idade mediana de 34 anos, divididos entre 32 do grupo SQ e 11 do grupo CQ. O grupo CQ autorrelatou rouquidão e maior dificuldade ao cantar no EASE e maiores escores nos protocolos IDV-10 e IFV. Foi evidenciada correlação positiva entre a dificuldade ao cantar e a desvantagem vocal com a fadiga de cantores amadores gospel, sendo que essa correlação foi maior para o grupo SQ. Conclusão Cantores com queixa vocal apresentaram maiores índices de fadiga vocal, desvantagem vocal e maior dificuldade para cantar após uma hora de apresentação. Cantores sem queixa podem ter a habilidade de cantar prejudicada pela fadiga vocal. Variações na habilidade ao cantar e desvantagens vocais de cantores amadores gospel podem ter relação direta com a fadiga vocal.

ABSTRACT Purpose To investigate the immediate impact on the voice of gospel singers with and without vocal complaints after a one-hour individual presentation. Methods Application of an online questionnaire that addressed the following aspects: 1 - Sociodemographic data; 2 - Self-assessment of the ability to sing using the Evaluation of the Ability to Sing Easily (EASE-BR) protocol; 3 - Self-assessment of vocal fatigue symptoms using the Vocal Fatigue Index (VFI) protocol; and 4 - Self-assessment of voice handicap using the Voice Handicap Index 10 (VHI-10) protocol. Participants were divided into two groups: Group with Vocal Complaint (WVC) and Group with no Vocal Complaint (WnVC) based on the total score of the IDV-10. Data underwent descriptive and inferential statistical analysis with a significance level of 5%. Results The study included 43 gospel singers with a median age of 34 years: 32 were in the WnVC group and 11 were in the WVC group. The WVC group reported hoarseness and experienced more difficulty while singing in the EASE, resulting in higher scores in both the VHI-10 and VFI protocols. A positive correlation was observed between singing difficulty and vocal handicap due to fatigue in amateur gospel singers, with this correlation being stronger within the WnVC group. Conclusion After one hour of performance, singers with vocal complaints exhibited higher rates of vocal fatigue, vocal disadvantage, and greater difficulty in singing. Singers without complaints may have their ability to sing impaired by vocal fatigue. Variations in singing ability and vocal handicaps in amateur gospel singers may be directly related to vocal fatigue.

The influence of listener experience, measurement scale and speech task on the reliability of auditory-perceptual evaluation of vocal quality

ABSTRACT Purpose To assess the influence of the listener experience, measurement scales and the type of speech task on the auditory-perceptual evaluation of the overall severity (OS) of voice deviation and the predominant type of voice (rough, breathy or strain). Methods 22 listeners, divided into four groups participated in the study: speech-language pathologist specialized in voice (SLP-V), SLP non specialized in voice (SLP-NV), graduate students with auditory-perceptual analysis training (GS-T), and graduate students without auditory-perceptual analysis training (GS-U). The subjects rated the OS of voice deviation and the predominant type of voice of 44 voices by visual analog scale (VAS) and the numerical scale (score "G" from GRBAS), corresponding to six speech tasks such as sustained vowel /a/ and /ɛ/, sentences, number counting, running speech, and all five previous tasks together. Results Sentences obtained the best interrater reliability in each group, using both VAS and GRBAS. SLP-NV group demonstrated the best interrater reliability in OS judgment in different speech tasks using VAS or GRBAS. Sustained vowel (/a/ and /ɛ/) and running speech obtained the best interrater reliability among the groups of listeners in judging the predominant vocal quality. GS-T group got the best result of interrater reliability in judging the predominant vocal quality. Conclusion The time of experience in the auditory-perceptual judgment of the voice, the type of training to which they were submitted, and the type of speech task influence the reliability of the auditory-perceptual evaluation of vocal quality.

Rehabilitación deglutoria y fonatoria de una paciente traqueostomizada. Reporte de caso / Swallowing and Phonatory rehabilitation of a tracheostomized patient. A case report

La traqueostomía es un procedimiento quirúrgico enfocado en brindar una vía de respiración alterna, en el que sus mayores consecuencias son las afectaciones comunicativas y deglutorias. La evaluación e intervención fonoaudiológica es indispensable dentro del proceso de rehabilitación de pacientes traqueostomizados, teniendo en cuenta las secuelas comunicativas, deglutorias y de fonación asociadas a este procedimiento. El presente artículo tiene como objetivo destacar el rol y actuar fonoaudiológico dentro de la restauración de las funciones alteradas en el caso de una paciente femenina con traqueostomía, quien acude al servicio de urgencias de un hospital público de Bogotá, Colombia. Se aplicaron pruebas estandarizadas y subjetivas para la valoración fonoaudiológica, estableciendo así el plan de manejo enfocado en la restauración de la deglución y la fonación, así como la intervención para el mantenimiento del estado orofacial, sensibilidad y movilidad de las estructuras.

O que cantores amadores que se apresentam em cultos religiosos conhecem sobre saúde e higiene vocal? / What do amateur singers who perform in religious services know about vocal health and hygiene?

RESUMO Objetivo Descrever o conhecimento de cantores amadores que se apresentam em cultos religiosos sobre saúde e higiene vocal e comparar esses achados em dois momentos distintos. Métodos Pesquisa descritiva, longitudinal, com 100 participantes que praticavam canto amador em cultos religiosos; idades entre 18 e 82 anos (média 33,72 anos), 54 mulheres e 46 homens. Os participantes responderam ao Questionário Inicial, que inclui dados pessoais e autoavaliação vocal, e ao Questionário de Saúde e Higiene Vocal, este em dois momentos, com intervalo de 20 dias e com as questões aleatorizadas. Foi dada devolutiva desse questionário após cada aplicação, por meio da apresentação das respostas corretas de cada um de seus itens. Os dados foram analisados de forma descritiva e inferencial. Resultados A maior parte dos cantores referiu algum grau de alteração vocal e relatou ao menos um sintoma vocal (principalmente pigarro e falha na voz). A pontuação foi maior na segunda aplicação do questionário e não houve correlação entre a autoavaliação vocal e a pontuação obtida. Conclusão Cantores amadores de ambos os gêneros que se apresentam em cultos religiosos demonstraram conhecimento sobre saúde e higiene vocal correspondente ao de indivíduos vocalmente saudáveis, acima do ponto de corte em ambas as aplicações do Questionário de Saúde e Higiene Vocal. Contudo, a maioria referiu alterações e sintomas vocais. Verificou-se aumento do conhecimento sobre saúde e higiene vocal na segunda aplicação, ainda que discreto. O nível de conhecimento sobre saúde e higiene vocal não se correlacionou com o grau de alteração vocal.

ABSTRACT Purpose To describe the knowledge of amateur singers who perform in religious services, about vocal health and hygiene, and compare these findings at two different moments. Methods Descriptive, longitudinal research with 100 participants who practice amateur singing in religious services; ages between 18 and 82 years (average 33.72 years), 54 women and 46 men. Participants answered the Initial Questionnaire (Q1), which includes personal data and vocal self-assessment, and the Vocal Health and Hygiene Questionnaire (QSHV), on two occasions with an interval of 20 days and with the questions randomized. The participants were given a feed-back of the QSHV after each application i.e. the correct answers to each item. The data were analyzed descriptively and inferentially. Results Most singers reported some degree of self-assessed vocal alteration and reported at least one vocal symptom (mainly throat clearing and voice failure). The score was higher in the second application of the QSHV and there was no correlation between the vocal self-assessment and the score obtained in the QSHV. Conclusion Amateur singers of both sexes who perform in religious services demonstrated knowledge about vocal health and hygiene corresponding to that of vocally healthy individuals, above the cutoff point in both applications; however, the majority reported vocal changes and symptoms. There was an increase in knowledge about vocal health and hygiene in the second application, however discreet. The level of knowledge about vocal health and hygiene did not correlate with the degree of vocal alteration.

How to build measurable treatment goals? A taxonomy of outcome criteria for vocal intervention monitoring

Introduction: The complexity of the vocal phenomenon hinders the therapist's ability to quickly and effectively monitor the achievements obtained by the patient through vocal intervention. The assessment of therapeutic progress relies on the therapist's capability to utilize valid, reliable, and meaningful outcome criteria. Aim: Develop a conceptual framework of outcome criteria to be used in the treatment plans designed by speech-language pathologists for patients with vocal complaints. Methodology: Qualitative, conceptual, and model-type research in which a critical review is conducted through a non-probabilistic theoretical sampling of the theoretical models of therapy treatment plans, the outcome criteria involved and their relevance to voice intervention. Building upon this, a taxonomy of outcome criteria is proposed for verifying therapeutic progress in voice therapy. Results: A conceptual outcome criteria framework is proposed. This model incorporates quantitative, qualitative, and mixed criteria to monitor the diverse aspects of vocal function in the context of voice intervention. Conclusion: The model provides a precise guide to assess the results achieved by the patient in vocal intervention through treatment goals.

Exploring the Feasibility of a Comprehensive Screening for Voice and Swallowing Function in Post-Extubation Patients: A Pilot Study

Objectives: This pilot study aimed to identify and test a battery of time-efficient and cost-effective voice and swallowing screening tools for post-extubated patients in Chile. Methods: A panel of four experts selected and rated voice and swallowing screening tools. Seven measures were selected: smoothed cepstral peak prominence (CPPS) and maximum phonation time (MPT) for voice assessment, Volume-Viscosity Swallow Test (V-VST) for swallowing, voluntary and reflex peak cough flow for cough assessment, Eating Assessment Tool-10 (EAT-10), and Vocal Symptom Scale (VoiSS) for patient-reported outcomes. These tools were applied to four post-extubation patients within 48-72 hours post-hospital discharge, alongside the assessment of 17 matched controls. Results: Post-extubation patients showed significantly shorter MPT, lower CPPS values, increased V-VST dysphagia signs, reduced voluntary peak cough flow, and more pronounced symptoms on both the VoiSS and EAT-10 compared to controls. Limitations: The study had a modest sample size and relied solely on clinical screening tools. Value: This pilot study suggests a feasible and cost-effective approach to voice and swallowing screening for post-extubation patients, valuable in resource-constrained settings. Conclusion: While these accessible tools are not gold-standard assessments, they offer valuable insights and can guide future research. This study underscores the potential of selected tools in facilitating early detection of voice and swallowing disorders in post-extubation patients.

Objetivos: Este estudio piloto tuvo como objetivo identificar y probar una batería de herramientas de detección de problemas de voz y deglución que fueran eficientes en cuanto a tiempo y costo para pacientes chilenos postextubados. Métodos: Un panel de cuatro expertos seleccionó y evaluó herramientas de detección de voz y deglución. Se seleccionaron siete medidas: prominencia de pico cepstral suavizado (CPPS) y tiempo máximo de fonación (TMF) para la evaluación de la voz, prueba de volumen-viscosidad (V-VST) para la deglución, flujo máximo voluntario y reflejo de la tos para evaluar la tos, Eating Assessment Tool-10 (EAT-10) y la Escala de Sintomas Vocales (ESV) para los resultados informados por los pacientes. Estas herramientas se aplicaron a cuatro pacientes postextubados (48-72 horas), junto con la evaluación de 17 controles pareados. Resultados: Los pacientes postextubados mostraron un TMF y CPPS significativamente más bajos, aumento de los indicios de disfagia en la V-VST, reducción del flujo máximo de la tos y síntomas más pronunciados tanto en la ESV como en la EAT-10 en comparación con los controles. Limitaciones: El estudio tuvo un tamaño de muestra reducida y se basó únicamente en herramientas de detección clínica. Valor: Este estudio piloto sugiere un enfoque factible y rentable para la detección de problemas de voz y deglución en pacientes postextubados, valioso en entornos con recursos limitados. Conclusión: Aunque ese abordaje no sustituye a las evaluaciones de referencia, ofrece información valiosa y puede guiar futuras investigaciones que busquen facilitar la detección temprana de los trastornos de la voz-deglución en pacientes postextubados.

Normative Values for the Spanish Version of the Voice Symptom Scale (VoiSS)

Objective: The aim of this study was to establish normative values for the Voice Symptom Scale (VoiSS) in the Spanish community population (without voice problems), using a sample from a large area of southeastern Spain. Method: The sample consisted of 115 adults from ages 16 to 87, 60 of whom were women and 55 were men. Participants included the family members of patients who attended the Otorhinolaryngology (ENT) and Speech Therapy Clinic at a referral hospital in the region of Murcia, Spain, and some of the clinic's staff. All the participants reported never having suffered from any voice disorder before. Results: The normative values obtained in this study for the VoiSS were 14.61 (SD=8.18) for the total score, 7.57 (SD = 5.42) for the Impairment subscale, 1.04 (SD = 1.65) for the Emotional subscale, and 5.99 (SD = 3.61) for the Physical subscale. The percentile values were also obtained for the VoiSS scale and for its three subscales. Conclusions: This study presents normative values for the VoiSS scale that have not previously been obtained in Spain. These values can be used as a reference to detect possible voice disorders.

Vocal Demand Response to the Educational Setting Based Communication Scenarios: A Single Subject Study

Objectives: This was a single-subject study, aimed to demonstrate different vocal demand situations that are typical for primary school and teacher's vocal demand response under two acoustical conditions, with and without voice amplification, during five working days. Methods: The long-term voice dosimetry with Vocal Holter Med (PR.O. Voice Srl) was carried out on a 49-year-old female teacher with voice disorders during daily teaching activities. A sound field amplification system (SFAS) PentaClass Runa was installed in the classroom. Voice dosimetry was provided under two different acoustical conditions: without SFAS (2 days) and with SFAS (3 days). Results: Phonation time percentage, sound pressure level (SPL), SPL SD, fundamental frequency (F0), F0 SD, cycle, and distance doses were investigated in seven communication scenarios (lessons, group/individual classes, sports lessons in the gym and schoolyard, breaks, lunch breaks, and other activities). The median scores of all voice parameters differed significantly between different vocal demand contexts. The significant statistical difference in the vocal demand response was in the communication situations with and without SFAS. In addition, the number of children, reverberation time, and ambient air relative humidity impacted voice SPL and the cycle dose. Conclusions: Lessons, sports lessons held in the gym or schoolyard, breaks, and lunch breaks were considered as high vocal demand communication situations requiring higher voice intensity and fundamental frequency, higher phonation time percentage, cycle, and distance doses. Group/individual work and other teacher activities during the day, unrelated to direct work with students, were categorized as low vocal demand communication scenarios.

Objetivos: Este fue un estudio de sujeto único, cuyo objetivo fue demostrar diferentes situaciones de demanda vocal típicas de la escuela primaria y la respuesta vocal de los docentes bajo dos condiciones acústicas, con y sin amplificación de voz, durante cinco días laborables. Métodos: Se llevó a cabo dosimetría vocal a largo plazo con Vocal Holter Med (PR.O. Voice Srl) durante las actividades diarias de enseñanza en una docente de 49 años con trastornos de la voz. Se instaló un sistema de amplificación de campo sonoro (SFAS) PentaClass Runa en el aula. La dosimetría vocal se realizó bajo dos condiciones acústicas diferentes: sin SFAS (2 días) y con SFAS (3 días). Resultados: Se investigaron el porcentaje de tiempo de fonación, el nivel de presión sonora (SPL), SPL SD, la frecuencia fundamental (F0), F0 SD, ciclos y dosis de distancia en siete escenarios de comunicación diferentes (clases, clases grupales/individuales, clases de educación física en el gimnasio y el patio de la escuela, recreos, almuerzos y otras actividades). Las puntuaciones medias de todos los parámetros vocales diferían significativamente entre los diferentes contextos de demanda vocal. La diferencia estadísticamente significativa en la respuesta a la demanda vocal se observó en las situaciones de comunicación con y sin SFAS. Además, el número de niños, el tiempo de reverberación y la humedad relativa del aire ambiente afectaron al SPL de la voz y la dosis de ciclo. Conclusiones: Las lecciones, las clases de educación física en el gimnasio o el patio de la escuela, los recreos y los almuerzos se consideraron situaciones de comunicación de alta demanda vocal, que requerían una mayor intensidad y frecuencia fundamental de la voz, un mayor porcentaje de tiempo de fonación y dosis de ciclo y distancia más altas. El trabajo grupal/individual y otras actividades del profesor durante el día no relacionadas con el trabajo directo con los estudiantes se categorizaron como escenarios de comunicación de baja demanda vocal.

Objective: To review articles published between 2002 and 2022 that have adapted and validated CAPE-V in different languages, to thoroughly evaluate the adaptation, methodology, and statistics used. Methods: A systematic review was conducted using Scopus, Google Scholar and PubMed to identify articles that adapted and/or validated CAPE-V between 2002 and 2022. The title and summary were analyzed to pre-select the sample. To evaluate the risk of bias of the included studies, the full text was critically analyzed. Results: The initial search identified 568 items. When duplicates were removed, 559 were reviewed and 23 were pre-selected. 12 were finally included and analyzed considering adaptation, methodology, and statistical analysis. The results show that the adaptation and validation of CAPE-V to different languages is essential to ensure accurate and reliable measurements in different populations. Analysis and discussion: There is heterogeneity in how CAPE-V is adapted and validated. However, all studies were successful in producing valid results, underlining the importance of these processes for clinical practice. Conclusions: Adaptations and validations of CAPE-V were performed heterogeneously due to the absence of a standard protocol. It is necessary to generate guidelines to perform these processes by providing this scale to the clinic, ensuring quality and reliability of results.

Risk of Dysphonia in Legal Professionals: Proposal for a Screening Protocol

Introduction: Due to the communicative requirements inherent to the profession, the legal professional benefits from speech therapy monitoring for the proper use of the voice and to avoid the occurrence of vocal disorders. The development of specific instruments will contribute with more relevant data to guide this monitoring. Objective: To verify the applicability of the General Dysphonia Risk Screening Protocol (DRSP-G) and the Specific Dysphonia Risk Screening Protocol for Legal Professionals (DRSP-LP) and to correlate the average scores of both with vocal deviation, sex, age, professional performance time, vocal signs and symptoms, and vocal self-assessment. Methods: Fifty legal professionals participated. All participants completed the DRSP-G and DRSP-LP and recorded their voices for detection of the presence of altered vocal quality. Results: Most participants presented a high risk of dysphonia, which was higher in men. Altered vocal quality was observed in 34% of the participants. The items with the highest scores in the DRSP-G were talking a lot (76%), excessive daily coffee intake (70%), contact with smokers (60%), and insufficient hydration and sleep (48%); in the DRSP-LP, alcohol consumption (68%) and exposure to air conditioning (64%). There was no correlation between risk scores and the degree of dysphonia, or with age or length of professional experience. The DRSP-G score correlated with vocal signs and symptoms and vocal self-perception. Conclusions: The joint application of the DRSP-G and the DRSP-LP enabled a quantitative and qualitative analysis of risk factors for dysphonia in legal professionals.

Evaluar cómo las condiciones de trabajo pueden afectar la salud vocal, evaluar el estrés laboral y valorar los cambios en la calidad vocal de profesoras de primaria de la comuna de Temuco.Método. Se evaluó a 18 profesoras de primaria de la comuna de Temuco, Chile, quienes se encontraban trabajando en modalidad de teletrabajo durante el año 2021, realizando una evaluación al comienzo y al final del año escolar, a través del Voice Handicap Index (VHI-30), Vocal Tract Disconfort (VTD), Maslach Burnout Inventory (MBI) y análisis acústico mediante medidas de perturbación y espectro promedio a largo plazo. Resultados. Solo el 21% de las profesoras contaba con un espacio físico adecuado para el teletrabajo. El 52,6% debía compartir responsabilidades del hogar, como el cuidado de hijos menores durante su jornada de teletrabajo. Los resultados muestran un aumento de la sintomatología y sensaciones de incomodidad a nivel del tracto vocal medidas mediante el VHI-30 y el VTD. En cuanto al estrés laboral medido por la escala de Burnout, solo se evidenció un valor significativo para la subescala agotamiento emocional. No se evidenciaron diferencias significativas en los parámetros acústicos Jitter, Shimmer, HNR y Alpha ratio. Conclusiones. La gran mayoría de las participantes manifestó un aumento del malestar y sintomatología vocal autopercibida (sequedad de garganta, fatiga vocal) en conjunto con un mayor nivel de estrés, lo que a la larga puede desencadenar trastornos de voz

Introduction. Teleworking as a result of COVID-19 has generated high demands that could promote the generation of vocal overexertion.Aim. To evaluate how working conditions assess changes in vocal health, evaluate work stress, and assess changes in the vocal quality of primary school teachers in the Temuco commune.Method. Eighteen elementary school teachers from the commune of Temuco, Chile, who were teleworking during the year 2021, were evaluated not only at the beginning but also at the end of the school year through the Voice Handicap Index (VHI-30), Vocal Tract Discomfort (VTD), Maslach Burnout Inventory (MBI), and acoustic analysis using long-term average spectrum and disturbance measurements.Results. Only 21% of the teachers had adequate physical space for teleworking. In addition, 52.6% had to share household responsibilities such as taking care of minor children during their teleworking day. The results show an increase in symptoms and sensations of discomfort at the level of the vocal tract measured by the VHI-30 and the VTD. Regarding job stress measured by the Burnout scale, only a significant value for the emotional exhaustion subscale was found. Besides, there were not found any significant differences in the acoustic parameters Jitter, Shimmer, HNR, and Alpha ratio.Conclusions. The vast majority of the participants reported increased discomfort and self-perceived vocal symptoms (dry throat, vocal fatigue) together with a higher level of stress, which in the long run can trigger voice disorders
