“…Professional singers can relate vocal fatigue to a reduced ability to project or sustain voice, reduced vocal power, pitch, and loudness, increased hoarseness, increased effort to produce voice, or general vocal constriction 36 . The gradual decrease in task performance in singers with vocal fatigue may be due to neuromuscular inefficiency, which may involve an inadequate phonatory pattern and inefficient muscle recruitment, may increase the energy demand for function performance, and may or may not involve deficit recovery 20,23 . Neuromuscular adjustments used for singing are sophisticated and require a sizeable vocal demand 6 , and any complaint that indicates a possible vocal alteration, mainly behavioral, can compromise the vocal performance and lead to a sensation of vocal effort, possibly due to neuromuscular inefficiency.…”

“…This reduction of oxygenation would cause a decrease in the ability to perform a task over time, which can be explained by neuromuscular inefficiency or a recovery deficit. Neuromuscular inefficiency may involve an inadequate phonation muscle pattern, while recovery deficit may be affected by lack of training [20][21][22][23] .…”

“…19 It is usually due to increased demand for use or vocal load, leading to the perception of vocal effort or discomfort, decreased flexibility and pitch range, and vocal projection. 20 Vocal fatigue is defined as a set of symptoms of self-perception, 19,21−24 a negative physiological consequence for a vocal load of task 19 ; a perceived progressive increase in phonatory effort and loss of phonatory skills 25,26 ; and a quantifiable decrease in both in functional performance and voice perception, which influences the vocal task performance. 27 Although vocal fatigue can improve with adequate vocal rest, 19 in the present study, there was no improvement of symptoms after rest.…”

Objective To analyze the vocal self-perception of individuals who wore face masks for essential activities and those who wore them for professional and essential activities during the coronavirus disease pandemic. Materials and Methods This was an observational, descriptive, cross-sectional study. The study included 468 individuals who were stratified into two groups: the Working Group, comprising individuals who wore face masks for professional and essential activities during the pandemic; and the Essential Activities Group, with individuals who wore face masks only for essential activities during the pandemic. The outcome measures tested were self-perception of vocal fatigue, vocal tract discomfort, vocal effort, speech intelligibility, auditory feedback, and coordination between speech and breathing. Descriptive and inferential statistics were performed. Results Face masks increased the perception of vocal effort, difficulty in speech intelligibility, auditory feedback, and difficulty in coordinating speech and breathing, irrespective of usage. Individuals who wore face masks for professional and essential activities had a greater perception of symptoms of vocal fatigue and discomfort, vocal effort, difficulties in speech intelligibility, and in coordinating speech and breathing. Conclusion Use of face masks increases the perception of vocal symptoms and discomfort, especially in individuals who wore it for professional and essential activities.

“…Exaustivas horas de aulas e a dificuldade para realizar um descanso vocal satisfatório são realidades encontradas entre os docentes, as quais os tornam susceptíveis a apresentar mais problemas vocais do que aqueles que não são professores, podendo a fadiga vocal ser um dos sinais e sintomas iniciais (17,20,21) . No entanto, ainda há uma baixa procura por tratamento precoce entre os docentes que apresentam queixas e sinais de alterações vocais, sendo essa busca, geralmente, quando o problema já está instalado e comprometendo o desempenho vocal desse profissional em sala de aula (20) .…”

RESUMO Objetivo Verificar a autopercepção da fadiga vocal e fatores associados em professores universitários em ensino remoto durante a pandemia de COVID-19. Métodos Estudo transversal, observacional, descritivo e analítico, com abordagem quantitativa com professores universitários em ensino remoto no período da pandemia de COVID-19. Os participantes, após o aceite, responderam a um questionário sociodemográfico, Questionário de Sinais e Sintomas Vocais, Protocolo Índice de Fadiga Vocal (IFV) e Protocolo Índice de Desvantagem Vocal 10 (IDF-10). A análise dos dados ocorreu por meio da estatística descritiva e inferencial. As associações entre as variáveis qualitativas foram verificadas por meio dos testes Qui-quadrado e Exato de Fisher. Já as médias do IFV e IDV-10, foram comparadas com o número de sinais e sintomas por meio do teste de Mann-Whitney. Resultados Amostra de 91 professores, maioria do gênero feminino (83,5%) e média de idade de 44,0 anos. Os professores apresentaram média de 3,8 sinais e sintomas e o escore total do IFV indicou a presença de risco para fadiga vocal, com valores compatíveis para indivíduos disfônicos. Não apresentaram desvantagem vocal. Conclusão Os professores universitários em ensino remoto se autoavaliaram apresentando risco para fadiga vocal. Entre os fatores associados ao IFV, os docentes que apresentaram mais de dois sinais e sintomas vocais tiveram maior sensação de fadiga vocal. Não foi observada autopercepção de desvantagem vocal, porém, aqueles que apresentaram mais de dois sinais e sintomas vocais tiveram pior autopercepção para desvantagem vocal.
