Purpose: to characterize and relate the vocal, occupational and general health profile of elementary school teachers from Santa Maria/RS. Methods: observational analytical cross-sectional study of quantitative character. The sample consisted by 127 teachers (average age of 38.25 years-old) who responded to a questionnaire and underwent hearing screening, perceptual voice assessment and acoustic analysis. Results: average of 7,03h/day of teaching; work as a teacher for 13,13 years on average; high occurrence of vocal complaints and there was no reports of respiratory disorders, alcoholism and smoking habits; most showed no disorders in the auditory perceptual parameters; the acoustic analysis presented disorders in measures of disturbance frequency, the amplitude and noise; the teachers who have submitted complaints vocals had daily workload higher than those that did not show; teachers with vocal complaints presented significant changes in measurement of the fundamental frequency variation (jitter); and it was found a statistically significant relationship between respiratory disorders and the measurement of the relative average frequency disturbance (jitter). Conclusion: there is high occurrence of vocal complaints among elementary school teachers, and these were related with the high workload and acoustic measures of jitter, which also presented relation to the related respiratory disorders. Keywords: Epidemiology; Dysphonia; Occupational Health; Voice RESUMO Objetivo: caracterizar e relacionar o perfil vocal, ocupacional e de saúde geral de professores do ensino fundamental de Santa Maria/RS. Métodos: estudo transversal observacional analítico de caráter quantitativo. A amostra constituiu-se de 127 professores (média de idade de 38,25 anos), que responderam a um questionário e foram submetidos à triagem auditiva, avaliação vocal perceptivoauditiva e avaliação acústica. Resultados: média de 7,03h/dia de docência; trabalho como docente há 13,13 anos em média; elevada ocorrência de queixas vocais e ausência de relato de distúrbios respiratórios e hábitos de etilismo e tabagismo; a maioria não apresentou alterações nos parâmetros perceptivoauditivos, e na análise acústica, apresentou alterações nas medidas de perturbação de frequência e amplitude e de ruído; os professores que apresentaram queixas vocais tinham carga horária diária superior aos que não apresentaram; os professores com queixas vocais apresentaram alterações significantes na medida variação da frequência fundamental (jitter); e verificou-se relação estatisticamente significante entre distúrbios respiratórios e a medida da média relativa da perturbação de frequência (jitter). Conclusão: há elevada ocorrência de queixas vocais entre professores do ensino fundamental e essas se relacionam com a carga horária elevada e com medidas acústicas de jitter que também apresentam relação com o relato da presença de distúrbios respiratórios.
Purpose: to characterize and to relate the quantity and hydration status, the voice use time and the dryness of complaints of professionals and future voice professionals. Methods: cross-sectional study, non-experimental, retrospective and quantitative, using database. There were analyzed records of 105 subjects of both genders, professionals and / or students future voice professionals at the age between 19:0-42:6 years. There were used data about age, profession, gender, quantity and hydration status, voice use time and dryness of complaints. There were used: Hypothesis test for Proportion, Chi-Square test and Fisher's exact test.Results: significant frequency of available water in the workplace and voice use less than eight hours. The intake of less than seven glasses of water daily was percentage higher than the intake of more than seven cups. There are significant associations between intake less water quantity and use the voice for less time and between having water at work and intake more than seven glasses of water every day. There was not significance in relation to dryness complaint. Conclusion: most of the voice professionals and future professionals used it for less than eight hours and had water available at work. Those who intake less than seven glasses of water daily a present daily time vocal use less than eight hours and those who drank more than seven cups of water a day had water available at work. Resultados: frequência significante de água disponível no ambiente de trabalho e de uso da voz menos de oito horas diárias. A ingestão de menos de sete copos diários de água foi percentualmente maior do que a ingestão de mais de sete copos. Houve associação significante entre ingerir menor quantidade de água e usar a voz por menor tempo e entre ter água no trabalho e ingerir mais de sete copos de água diários. Não houve qualquer significância em relação à queixa de ressecamento. Conclusão: a maioria dos profissionais e futuros profissionais da voz a utilizava por menos de oito horas diárias e possuía água disponível no trabalho. Aqueles que ingeriam menos de sete copos de água diários apresentavam tempo diário de uso vocal menor do que oito horas e aqueles que ingeriam mais de sete copos de água por dia tinham água disponível no trabalho.
O tema deste estudo é a Síndrome de tensão musculoesquelética, musculatura laríngea extrínseca e postura corporal. Tem como objetivo descrever, a partir de revisão de literatura,as características da musculatura extrínseca da laringe; postura corporal; Síndrome de tensão musculoesquelética e suas implicações vocais; avaliação e tratamento fisioterapêutico e fonoaudiológico. Foi realizado levantamento bibliográfico dos últimos 13 anos em que foram incluídos artigos cujo objetivo e/ou corpo do texto estivessem em consonância com os objetivos do estudo. A pesquisa foi realizada nos bancos de dados das bases Literatura Latino-Americana e do Caribe em Ciências da Saúde, Biblioteca Regional de Medicina, PublicMedline, Medical Literature Analysis and Retrieval System on Line, Scientific Electronic Library Online e Google Schoolar. Estabeleceram-se relações importantes do âmbito fisioterapêutico e fonoaudiológico, dentre as quais se destacam as relações musculares, posturais e funcionais na sinergia do aparato vocal. Na fisioterapia para redução da tensão muscular, a literatura aponta uso de eletroterapia transcutânea, laser de baixa intensidade, laser acupuntura, crioterapia, bem como terapia manual com tração, massagens, manipulações e mobilizações cervicais, associadas ou não a exercícios, alongamentos, relaxamento isométrico, mobilização assistida dos tecidos moles, exercícios terapêuticos visando à correção e equilíbrio muscular, reeducação respiratória diafragmática e terapia com flexão craniocervical. Na fonoaudiologia, foram encontrados apenas estudos com a manipulação digital da laringe e exercícios de trato vocal semiocluído.
Introduction: Knowledge about effective vocal techniques will contributes to the prevention/treatment of work-related voice disorder. Purpose: Verifying acoustic vocal, auditory-perceptive and videolaryngostroboscopic measures in dysphonic teachers of two groups before and after a brief and intensive therapy program with finger kazoo technique, comparing to their control groups, and comparing the study groups between themselves. Methods: Randomized study, pre-test and post-test, with control group, blind to the evaluator. Two study groups, with and without structural laryngeal affection (24 dysphonic teachers) performed15 sessions of a brief and intensive care with finger kazoo over three weeks and they were compared to two control groups (17 dysphonic teachers), who did not do therapy, in a total of 41 subjects. We carried out vocal acoustic analysis (Multi-Dimensional Voice Program Advanced), perceptual analysis (by three speech therapists) and videolaryngostroboscopy analysis (by three otolaryngologists) to compare the results obtained by each group. Results: Significant reduction in harmonic-noise ratio in the study group with alteration after therapy was observed. In the comparison between the study group without affection with the respective control, there was a significant decrease in jitter, shimmer and voiceless segments in favor of the study group. It was also observed a significant reduction in dysphonia, hoarseness, breathiness and tension levels, as well as a lower incidence of triangular slit -level II -and higher amplitude of vibration of the vocal folds in the study group with alteration. Conclusion: The brief and intensive care with finger kazoo provided voice, glottal closure and amplitude of mucosal wave vibration of the vocal folds improvements in dysphonic teachers with and without structural alterations of the vocal folds, especially in teachers without structural alterations.
Purpose: Correlating the Voice-Related Quality of Life (VRQOL), perceptual-auditory and acoustic assessment of teachers with vocal complaints. Methods: The study included 74 teachers aged between 20 and 62 years (mean 38.75 years). Self-assessment of VRQOL, voice perceptual-auditory assessment, acoustic voice analysis of glottal and spectrographic source, in narrowband (NB) and wideband (WB) and relevant statistical analysis were carried out. Results: There was a negative correlation between VRQOL and fundamental frequency (f0), maximum f0 and standard deviation of f0; roughness and amplitude variation.
For this literature review, we researched national and international scientific publications on vocal warm--up and cool-down of the speaking voice, through databases such as Lilacs, MedLine and Scielo, in order to identify and describe the methodological parameters and the effects of the vocal warm-up and cool-down proposals that are described in national and international literature. We performed the location and selection of studies through a survey of texts published on the theme from 1999 to 2013. We included original research articles; published in Portuguese or English; with emphasis on vocal warm-up and cool-down; associated or not. The recommended time of execution for warm-up ranged from 15 to 30 minutes or three sets of 15 repetitions, and the cool-down from 5 to 15min. The most used exercises for warm-up were voiced fricative sounds and vibrant of tongue or lips, in ascending scales, and for the vocal cool-down the nasal sounds, fricative sounds and vibrant of tongue or lips, in descending scales, were the most used exercises. The exercises showed positive vocal changes, observed by vocal acoustic and auditory-perceptual vocal and, self-evaluation and aerodynamic related to phonation. There was unanimity on the importance of completing the vocal warm-up and cool-down for voice professionals and on the positive results after carrying out the procedures. There was no agreement on the time of execution and on the exercises that were used. Keywords: Warm-up Exercise; Voice Quality; Voice Training; Voice; Speech, Language and Hearing Sciences RESUMO Esta revisão da literatura levantou publicações científicas nacionais e internacionais sobre aquecimento e desaquecimento vocais da voz falada, por meio das bases de dados Lilacs, MedLine e Scielo, com o objetivo de identificar e descrever os parâmetros metodológicos e os efeitos das propostas de aquecimento e desaquecimento vocal descritas na literatura nacional e internacional. Foi realizada a localização e seleção dos estudos por meio de levantamento de textos publicados sobre o assunto no período de 1999 a 2013. Foram incluídos artigos originais de pesquisa; publicados na língua portuguesa ou inglesa; que pesquisaram aquecimento e desaquecimento vocal; associados ou não. O tempo de execução recomendado para o aquecimento variou de 15 a 30min ou três séries de 15 repetições, e para o desaquecimento foi de 5 a 15min. Os exercícios mais utilizados para o aquecimento foram sons fricativos sonoros e vibrantes de língua ou de lábios, em escalas ascendentes, e para o desaquecimento vocal foram sons nasais, fricativos sonoros e vibrantes de língua e ou de lábios, em escalas descendentes. Os exercícios mostraram mudanças vocais positivas, observadas por meio de medidas vocais acústicas e perceptivoauditivas, de autoavaliação e aerodinâmicas relacionadas à fonação. Houve unanimidade quanto à importância da realização do aquecimento e desaquecimento vocais para profissionais da voz e aos resultados positivos após a realização dos procedimentos.
