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.

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.

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.

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.

Introducción: La complejidad del fenómeno vocal dificulta que el/la terapeuta monitoree de manera rápida y eficaz los logros obtenidos por el/la usuario/a mediante la intervención fonoaudiológica. La evaluación del avance terapéutico depende de la habilidad del/la terapeuta para emplear criterios de medición válidos, confiables y significativos. Objetivo: Desarrollar un modelo teórico de criterios de logro para su consideración en la formulación de los objetivos operacionales en las planificaciones terapéuticas que emplean los profesionales fonoaudiólogos en la atención de usuarios/as que presentan queja vocal. Metodología: Investigación cualitativa, de tipo conceptual y modélica, en la que se lleva a cabo una revisión crítica de la literatura a través de un muestreo teórico no probabilístico de los modelos teóricos propuestos para la formulación y medición de objetivos en el contexto terapéutico y sus alcances respecto de la intervención vocal. A partir de ello, se propone una taxonomía de criterios de logro para la verificación del avance terapéutico. Resultados: Se propone una taxonomía organizada en torno a criterios de logro cuantitativos, cualitativos y mixtos, los que son propuestos para el monitoreo de diversos aspectos de la función vocal en el contexto de la intervención fonoaudiológica. Conclusión: El modelo proporciona una guía precisa para evaluar de manera efectiva el progreso y los resultados alcanzados por el/la usuario/a en el abordaje fonoaudiológico vocal a través de los objetivos operacionales planteados para la intervención.

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.

Objetivo: El objetivo de este estudio fue establecer valores normativos para la escala Voice Symptom Scale (VoiSS) en población comunitaria española (sin problemas de voz), utilizando una muestra de un área extensa del sureste de España. Metodología: La muestra estuvo compuesta por 115 personas (60 mujeres y 55 hombres) con edades comprendidas entre los 16 y 87 años. Los participantes eran familiares que acompañaron a los pacientes a las sesiones clínicas de ORL y de Logopedia de un hospital de referencia de la Región de Murcia, así como personal del hospital. Todos declararon no padecer ningún trastorno de la voz. Resultados: Los valores normativos obtenidos en este estudio para el VoiSS fueron 14.61 (SD=8.18) para la puntuación total, 7.57 (SD = 5.42) para la subescala Limitación, 1.04 (SD = 1.65) para la subescala Emocional y 5.99 (SD = 3.61) para la subescala Física. Los valores percentílicos se obtuvieron también para la escala VoiSS y para sus tres subescalas. Conclusiones: Este estudio presenta valores normativos para la escala VoiSS que no han sido todavía obtenidos en España. Estos valores pueden utilizarse como referencia para detectar posibles trastornos de voz.

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.

Consensus Auditory Perceptual Evaluation of Voice (CAPE-V): revisión sistemática de los métodos utilizados para su adaptación y validación

Introducción: CAPE-V es ampliamente utilizado para evaluación perceptual vocal y ha sido adaptado y validado en múltiples idiomas. A través de un análisis exhaustivo, este estudio buscó avanzar en establecer un estándar en el método utilizado para su adaptación y validación. Objetivo: Revisar los artículos publicados entre 2002 y 2022 que han adaptado y validado CAPE-V a distintos idiomas, para evaluar exhaustivamente la adaptación, metodología y estadísticas utilizadas. Métodos: Se realizó una revisión sistemática utilizando Scopus, Google Scholar y PubMed para identificar artículos que adaptaran y/o validaran CAPE-V entre 2002 y 2022. Se analizó el título y resumen para preseleccionar la muestra. Para evaluar el riesgo de sesgo de los estudios incluidos se analizó de forma crítica el texto completo. Resultados: La búsqueda inicial identificó 568 artículos. Al eliminar duplicados se revisaron 559 y 23 fueron preseleccionados. 12 se incluyeron finalmente y fueron analizados, considerando adaptación, metodología y análisis estadístico. Los resultados revelan que la adaptación y validación de CAPE-V a diversos idiomas es fundamental para garantizar mediciones precisas y confiables en diferentes poblaciones. Análisis y discusión: Existe heterogeneidad en la forma de realizar la adaptación y validación de CAPE-V. No obstante, todos los estudios tuvieron éxito en producir resultados válidos, subrayando la importancia de estos procesos para la práctica clínica. Conclusiones: Las adaptaciones y validaciones de CAPE-V se realizaron heterogéneamente por ausencia de un protocolo estándar. Es necesario generar orientaciones para realizar estos procesos por el aporte de esta escala a la clínica, asegurando calidad y confiabilidad de los resultados.

Introduction: CAPE-V is widely used for vocal perceptual evaluation and has been adapted and validated in multiple languages. Through an exhaustive analysis, this study sought to advance in establishing a standard in the method used in its adaptation and validation. 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.

Introducción: Debido a las exigencias comunicativas inherentes a la profesión, el profesional del derecho se beneficia del seguimiento logopédico para el correcto uso de la voz y para evitar la aparición de trastornos vocales. El desarrollo de instrumentos específicos contribuirá con datos más relevantes para guiar este seguimiento. Objetivo: Verificar la aplicabilidad del Protocolo General de Detección de Riesgo de Disfonía (DRSP-G) y el Protocolo de Detección de Riesgo Específico para Profesionales del Derecho (DRSP-LP) y correlacionar las puntuaciones de ambos con varias variables de interés. Metodología: Participaron 50 profesionales del derecho. Todos completaron el DRSP-G y DRSP-LP y grabaron sus voces para detectar la presencia de alteraciones en la calidad de la voz. Resultados: La mayoría presentó un alto riesgo de disfonía, que fue mayor en los hombres. Se observó alteración en la calidad de la voz en el 34% de los participantes. Los ítems con puntajes más altos en el DRSP-G fueron hablar mucho (76%), ingesta diaria excesiva de café (70%), contacto con fumadores (60%) e hidratación y sueño insuficientes (48%); y en el DRSP-LP, consumo de alcohol (68%) y exposición al aire acondicionado (64%). No hubo correlación entre las puntuaciones de riesgo y el grado de disfonía, ni con la edad o la antigüedad profesional. La puntuación DRSP-G se correlacionó con los signos y síntomas vocales y la autopercepción vocal. Conclusiones: La aplicación conjunta del DRSP-G y el DRSP-LP permitió un análisis cuantitativo y cualitativo de los factores de riesgo de disfonía en profesionales del derecho.

Preliminary analysis of the effect of individualized voice therapy on pediatric voice disorders / 临床耳鼻咽喉头颈外科杂志

Objective:To determine the effectiveness of individualized voice therapy in persistent pediatric voice disorders. Methods:Thirty-eight children who were admitted to the Department of Pediatric Otolaryngology Shenzhen Hospital, Southern Medical University due to persistent voice disorder from November 2021 to October 2022 were included. All children were evaluated by dynamic laryngoscopy before voice therapy. Two voice doctors performed GRBAS score and acoustic analysis on the children's voice samples to obtain the relevant parameters including F0, Jitter, Shimmer, and MPT; All children were given personalized voice therapy for 8 weeks. Results:Among 38 children with voice disorders, 75.8%（29 cases） were diagnosed with vocal nodules, 20.6%（8 cases） were vocal polyps, and 3.4%（1 case） were vocal cysts. And in all children. And 51.7%（20 cases） had the sign of supraglottic extrusion under dynamic laryngoscopy. GRBAS scores decreased from 1.93 ± 0.62, 1.82 ± 0.55, 0.98 ± 0.54, 0.65 ± 0.48, 1.05 ± 0.52 to 0.62 ± 0.60, 0.58 ± 0.53, 0.32 ± 0.40, 0.22 ± 0.36, 0.37 ± 0.36. F0, Jitter, Shimmer decreased from（243.11±39.73） Hz, （0.85±0.99）%, （9.96±3.78）% to（225.43±43.20） Hz, （0.33±0.57）%, （7.72±4.32）%, respectively MPT was prolonged from（5.82±2.30） s to（7.87±3.21） s after treatment. All parameters changes had statistical significance. Conclusion:Voice therapy can solve children's voice problems, improve their voice quality and effectively treat children's voice disorders.

Odinofonía: una actualización clínica

Introducción: En la actualidad, la odinofonía es considerada como un síntoma más dentro de los desórdenes de la voz y, por lo mismo, su estudio ha tenido una relevancia menor en comparación a la investigación del dolor expresado en otras regiones del cuerpo humano. Objetivo: Actualizar el concepto de odinofonía, según los últimos hallazgos que explican su etiología, evaluación y manejo terapéutico. Método: Se buscaron trabajos en las bases de datos PubMed, Scopus, ScienceDirect y SciELO. Se seleccionaron artículos según diversos criterios, que incluyeron la fecha de publicación, el diseño y el objetivo. Resultados: La etiología de la odinofonía incluye, según criterios de intensidad y cronicidad del dolor, a la odinofonía primaria y secundaria. La evaluación de la odinofonía comprende una detallada entrevista clínica; la identificación, mediante escalas e índices, de su frecuencia, intensidad y duración; y la aplicación de herramientas como la algometría, para reconocer el grado de sensibilidad de los tejidos afectados. La intervención de la odinofonía depende de su naturaleza (primaria o secundaria) y, en general, incluye al abordaje educativo, sintomático, biomecánico y psicosocial. Conclusión: La literatura actual posiciona a la odinofonía como una condición compleja, cuya etiología, evaluación e intervención aún carecen de total comprensión.

Introduction: At present, odynophonia is considered one more symptom within voice disorders and, therefore, its study has had less relevance if compared to the research of pain expressed in other regions of the human body. Objective: To update the concept of odynophonia, according to the latest findings that explain its etiology, evaluation and therapeutic management. Methodology: The databases PubMed, Scopus, ScienceDirect, and SciELO were searched. Articles were selected according to various criteria, including date of publication, design and objective. Results: The etiology of odynophonia, according to criteria of intensity and chronicity of pain, includes primary and secondary odynophonia. The evaluation of odynophonia entails a detailed clinical interview; the identification of its frequency, intensity and duration using scales and indexes; and the application of tools such as algometry, to recognize the degree of sensitivity of the affected tissues. The intervention of odynophonia depends on its nature (primary or secondary) and, in general, includes educational, symptomatic, biomechanical and psychosocial approaches. Conclusion: Current literature positions odynophonia as a complex condition, whose etiology, evaluation, and intervention are still not fully understood.

Estudio preliminar para la validación de la versión chilena del Vocal Tract Discomfort-VTD en población docente / Validation of the chilean version of the Vocal Tract Discomfort-VTD on teachers: a preliminary study

Debido a la carga vocal a la que están expuestos los profesionales de la voz, como los profesores, son frecuentes los trastornos de voz y mal uso vocal en este grupo, lo que hace necesario poder contar con instrumentos de pesquisa rápidos y sencillos para un diagnóstico precoz de sintomatología vocal. El objetivo del presente estudio es realizar una adaptación y validación preliminar de la pauta "Vocal Tract Discomfort Scale (VTD)" al idioma español chileno en profesores. Se comenzó con la traducción al español del instrumento original por parte de dos expertos nativos y luego la retro-traducción por dos expertos en idioma inglés para determinar concordancias y discrepancias. Luego se continuó con la validación de apariencia y contenido realizada por valoración de grupo de expertos compuesto por dos metodólogos y cinco fonoaudiólogos con experiencia en el área vocal. La validez de criterio se obtuvo mediante la correlación entre la escala en estudio y el Voice Handicap Index en su versión validada al español como prueba gold-standard, para lo cual se aplicó en una muestra de 31 docentes. La validación de la escala VTD es fiable y deja a disposición de los fonoaudiólogos una herramienta sencilla y comprensible para el entendimiento del impacto generado en personas con disfonía, particularmente, en profesionales de la voz como los profesores.

Due to the vocal load to which voice professionals such as teachers are exposed, voice disorders and vocal misuse are frequently found in this group. This makes it necessary to have quick and simple assessment instruments that allow early detection of vocal symptoms. The objective of this study was to adapt the "Vocal Tract Discomfort Scale (VTD)" to Chilean Spanish and carry out a preliminary validation of this protocol on teachers. First, the original instrument was translated toSpanish by two native speakers, and then back-translated by two English experts, in order to determine the presence of agreements and discrepancies. Subsequently, a group of experts made up of two methodologists and five speech therapists with experience in the voice field performed an appearance and content validation. Criterion validity was obtained through the correlation between the Vocal Tract Discomfort Scale and the Spanish-validated version of the Voice Handicap Index as a gold-standard test, for which the first was appliedto a sample of 31 teachers. The validation of the VTD scale is reliable and provides speech therapists with a simple and understandable tool that allows them to comprehend the impact of dysphonia on people, particularly on voice professionals such as teachers.

Futuros professores e a autopercepção de sintomas vocais e conhecimento em saúde e higiene vocal / Future teachers and the self-perception of vocal symptoms and knowledge about vocal health and hygiene

RESUMO Objetivo Analisar respostas de futuros professores quanto à autopercepção de sintomas vocais e conhecimento sobre saúde vocal e higiene vocal, relacionando-os às variáveis sociodemográficas, ocupacionais e conhecimento prévio sobre voz. Método Estudo observacional, analítico e transversal. Participaram 264 alunos de licenciatura, foram aplicados Questionário de Saúde e Higiene Vocal (QSHV), Escala de Sintomas Vocais (ESV) e questionário com perguntas sociodemográficas, ocupacionais e vocais. Os dados foram analisados estatisticamente considerando nível de significância 5%. Resultados QSHV de futuros professores apresentou escore médio total de 21,89, sugestivo de conhecimento insuficiente sobre saúde e higiene vocal. Resultados da ESV estão acima da nota de corte do instrumento, nos três domínios e no escore total, observou-se maior sintomatologia em estudantes do primeiro ano quando comparados aos demais estudantes, nos domínios emocional, limitação e total. Houve diferença na comparação do QSHV com o ano da graduação (p=0,001), em que alunos dos terceiros e quartos anos obtiveram pontuações maiores. Observou-se correlação positiva entre escore total do QSHV e variável idade (p=0,019). Conclusão Futuros professores apresentam sintomatologia vocal importante, compatível aos indivíduos disfônicos, e possuem conhecimento insuficiente sobre saúde e higiene vocal. O conhecimento é ainda menor em alunos dos anos de graduação iniciais e com menor idade. Futuros professores com mais idade demonstram ter mais conhecimento sobre saúde e higiene vocal. Faz-se necessária a proposição de ações preventivas à essa população, ainda no período da graduação, visando à diminuição dos riscos ao desenvolvimento de problemas vocais em médio ou longo prazo durante a docência.

ABSTRACT Purpose To analyze responses of future teachers regarding the self-perception of vocal symptoms and knowledge about vocal health and vocal hygiene, relating them to sociodemographic and occupational variables and previous knowledge about voice. Methods Observational, analytical and cross-sectional study. A total of 264 undergraduate students participated and the Vocal Health and Hygiene Questionnaire (QSHV), Vocal Symptoms Scale (ESV) and a questionnaire with sociodemographic, occupational and vocal questions were applied. Data were statistically analyzed considering a 5% significance level. Results QSHV of future teachers had a total mean score of 21.89, suggestive of lack of knowledge about vocal health and hygiene. The results of the ESV are above the instrument's cutoff score, in each of the three domains and in the total score, there was greater symptomatology in first-year students when compared to other students, in the emotional, limitation and total domains. There was a difference when comparing the QSHV with the year of graduation (p=0.001), in which third and fourth year students obtained higher scores. A positive correlation was observed between the total QSHV score and the age variable (p=0.019). Conclusion Future teachers present important vocal symptomatology, compatible with dysphonic individuals, and have insufficient knowledge about vocal health and hygiene. Knowledge is even lower among students in the early undergraduate years and at a younger age. Older future teachers demonstrate more knowledge about vocal health and hygiene. It is necessary to propose preventive actions with this population, even during the graduation period, aiming to reduce the risks of developing vocal problems in the medium or long term during teaching.

Análise dos tempos de execução da técnica de sons vibrantes em idosas / Analysis of different performance times of the voiced trill technique in older women

RESUMO Objetivo Analisar e comparar os efeitos vocais imediatos da técnica de sons vibrantes sonoros na avaliação de medidas acústicas e perceptivo-auditivas de idosas com e sem autopercepção de alteração vocal. Método Estudo clínico quase experimental, envolvendo 53 idosas com idade entre 60 e 70 anos. Foi aplicado um questionário de autopercepção vocal, avaliação vocal e laríngea, antes e após a realização da técnica vocal com sons vibrantes sonoros. Antes e durante os intervalos da técnica, foram coletadas amostras de vogais sustentadas, totalizando quatro amostras. As mulheres idosas foram divididas em dois grupos: grupo com autopercepção de alteração vocal (n = 25) e grupo sem autopercepção de alteração vocal (n = 28). Foram realizadas avaliações perceptivo-auditivas e análise acústica. Os testes estatísticos foram utilizados para correlacionar os dados: Teste Anova para medidas repetidas, Teste de Friedman e Teste de Wilcoxon e Teste Qui-Quadrado de Pearson. Para todos os testes foi considerado nível de significância de 5%. Resultados Houve predomínio de disfonia moderada em ambos os grupos, de acordo com a julgamento perceptivo-auditivo. Não houve diferença estatisticamente significante entre os grupos na avaliação da análise perceptivo-auditiva quanto à melhora, piora e voz inalterada antes e após os diferentes tempos de execução da técnica. A maioria das idosas melhorou a voz após um minuto de execução da técnica. Conclusão As idosas apresentam elevada presença de alteração vocal quando considerada o julgamento perceptivo-auditivo da voz. Não houve evidências científicas quanto ao momento ideal para se obter um melhor efeito na voz das idosas.

ABSTRACT Purpose To analyze and compare the immediate vocal effects of the voiced trill technique in the assessment of acoustic and auditory-perceptual measures of older women with and without self-perceived vocal changes. Methods Clinical, quasi-experimental study in older women, aged 60 to 70 years (n=53). A questionnaire on vocal self-perception, voice, and laryngeal assessment was applied, before and after performing the voiced trill technique. Before and during intervals of the technique, sustained vowel samples were collected, totaling four samples. Older women were divided into two groups: one with self-perceived voice changes (n=25), and the other without self-perceived voice changes (n=28). Auditory-perceptual assessments and acoustic analysis were performed. Statistical tests were used to correlate the data: ANOVA Test for repeated measures, Friedman Test, Wilcoxon Test, and Pearson's Chi-Square Test. For all tests, the significance level was set at 5%. Results There was a predominance of moderate dysphonia in both groups, according to the auditory-perceptual judgment. There was no statistically significant difference between the groups in the assessment of the auditory-perceptual analysis regarding voice changes (improved, worsened, and unaltered voices) before and after the different technique performance times. Most older women improved their voice after 1 minute of performing the technique. Conclusion Older women often have voice changes when considering the perceptual judgment of the voice. There was no scientific evidence as to the ideal time to obtain a better effect on older women's voices.
