Respiratory and Laryngeal Function During Spontaneous Speaking in Teachers with Voice Disorders

Lowell, Soren January 2005 (has links)
Purpose: The purpose of this study was to determine if respiratory and laryngeal function during spontaneous speech production were different for teachers with voice disorders as compared to teachers without voice problems. The basic research questions posed in this study, as assessed during spontaneous speaking were: 1) Do subjects with a voice disorder show differences in lung volume patterns relative to control subjects? 2) Do subjects with a voice disorder show differences in vocal fold approximation as measured by contact quotient and contact index relative to control subjects? 3) Are these between-group differences most pronounced for mock teaching tasks versus a conversational speaking task? 4) Do subjects with a voice disorder rely more on laryngeal versus respiratory-based strategies for increasing loudness level as compared to control subjects?Method: Nine teachers with and nine teachers without voice problems were included in this study. Respiratory function was measured with magnetometry, and laryngeal function was measured with electroglottography. Respiratory and laryngeal function were measured during three spontaneous speaking tasks: a simulated teaching task at a typical and increased loudness level, and a conversational speaking task. Two structured speaking tasks were included for comparison of electroglottography measures: a paragraph reading task and a sustained vowel.Results: Lung volume termination level in spontaneous speaking was significantly lower for the teachers with voice disorders relative to teachers without voice problems. Lung volume initiation level was lower for the teachers with versus without voice problems during teaching-related speaking tasks. Laryngeal function as assessed with electroglottography did not show between-group differences. Across tasks, the measure of contact index was lower (more negative) during the conversational speaking task as compared to the sustained vowel task, indicating greater contact phase asymmetry during vocal fold vibration.Conclusions: These findings suggest that teachers with a voice disorder use different speech breathing strategies than teachers without voice problems. Management of teachers with voice problems may need to incorporate respiratory training that alters lung volume levels during speaking. Future research is needed to determine whether altering such patterns results in improved voice parameters and self-perceived improvement in vocal symptoms.

Profesijos ir balso sutrikimų ryšys / THE RELATIONSHIP BETWEEN AN OCCUPATION AND VOICE DISORDERS

Ulytė, Agnė 11 February 2012 (has links)
Darbe atlikta teorinė balso sutrikimų sampratos bei balso sutrikimų atsiradimo aiškinimo teorijų analizė. Anketinės apklausos metodu buvo atliktas tyrimas, kurio tikslas – išsiaiškinti profesijos ir balso sutrikimų ryšį. Atlikta statistinė (aprašomoji procentų, x2 testo) duomenų analizė. Tyrime dalyvavo 308 respondentai. Kauno klinikų medicinos darbuotojai (40), Naujosios Akmenės ligoninės medikai (50), Šiaulių miesto pedagogai (89) iš jų lopšelio – darželio auklėtojų (23), tiksliųjų ir humanitarinių mokslų mokytojų (35), pradinių klasių mokytojų (31). Taip pat buvo apklausti pardavėjai (36), vadybininkai (27 ), įstaigų vadovai (31 ) bei nekvalifikuoti darbininkai (35). Empirinėje dalyje nagrinėjamas profesijos ir balso sutrikimų ryšys. Taip pat bandoma išsiaiškinti, ar yra ryšys tarp lyties ir problemų susijusių su balsu. Svarbiausios empirinio tyrimo išvados: 1. Pedagoginės, psichologinės ir medicininės literatūros analizė atskleidė, kad pagrindinės balso sutrikimų atsiradimo priežastys yra pinkaudžiavimas balsu ir netinkamas jo vartojimas. 2. Pedagogo profesija patenka į didžiausią rizikos grupę, pagal balso sutrikimų atsiradimą, o darbininkai ir vadybininkai mažiausiai jaučia neigiamų balso pokyčių. 3. Pojūčius bei pokyčius, susijusius su balso sutrikimų atsiradimu, dažniausiai jaučia lopšelio – darželio auklėtojai, o mažiausiai – darbininkai, vadybininkai bei vadovaujantis personalas. 4.

Análise perceptivo-auditiva e acústica em mulheres com nódulos vocais

Zitta, Simone Maganhotto 2010 October 1914 (has links)
A proposta deste trabalho foi estudar a avaliação perceptivo-auditiva e acústica de 25 indivíduos do gênero feminino, sendo 20 com nódulos vocais e 5 com laringe e vozes normais. O software VoxMetria. foi instrumento de análise para os dados acústicos. O estudo foi aprovado pela Comissão de Ética em Pesquisa (CEP) do Hospital Erasto Gaertner, em Curitiba/ Paraná e os indivíduos selecionadas foram submetidos a três avaliações: laringológica, perceptivo-auditiva e acústica. Para o exame de laringe, utilizou-se a videolaringoestroboscopia. Para a avaliação perceptivo-auditiva da qualidade vocal, utilizouse a escala RASAT. E e os parâmetros de freqüência fundamental (f0), a medida de ruído GNE (glottal to noise excitation ratio) e a espectrografia vocal para a análise acústica; sendo utilizado a vogal sustentada [é]. Os resultados revelaram que os valores da freqüência fundamental foram mais graves no grupo com nódulos vocais e o parâmetro GNE não mostrou-se sensível na avaliação dos dois grupos, apresentando os resultados dentro dos padrões de normalidade. A avaliação perceptivo-auditiva e a espectrografia vocal revelaram diferenças significativas entre as vozes normais e com nódulos vocais. A espectrografia vocal mostrou-se extremamente confiável quando comparada à avaliação perceptivo-auditiva da qualidade vocal. / This work ayms to study the perceptual evaluation and the acoustic analysis in 25 women. In this population, 20 women had vocal nodule and 5 had normal voices and larynx. It was defined the vocal node as the interest pathology, which is a reaction to the excessive use of the voice, that induces to the constant vocal folds movement. It was used VoxMetria software to analise the acoustic data. This research was approved by Hospital Erasto Gaertner Research and Ethics Commission, in Curitiba/ Paraná. The selected women were submitted to 3 evaluations: laryngological, perceptual and acoustic. In the larynx exam it was used the “videolaringoestroboscopia”. In the perceptual evaluation it was used the RASAT scale. The basic frequency parameters (f0), the noise measure GNE (glottal to noise excitation ratio) and the vocal spectrogram, to the acoustic analysis, where it was used the supported vowel [é]. The results showed that the basic frequency values were more thick in the group with vocal nodule and the noise measure GNE wasn’t sensitive in both group analysis and showed normal results. The perceptual evaluation and the vocal spectrogram revealed significant differences between the two groups. The vocal spectrogram were really sensitive when compared to the perceptual evaluation

Teixeira, Mariane Zulian de Marqui January 2002 (has links)
Resumo: Alterações na voz das crianças são geralmente confundidas pelos pais com sintomas de infecções de vias aéreas superiores ou tachadas como qualidade normal da voz. Foram objetivos deste trabalho verificar a opinião dos pais sobre a voz de seus filhos no que diz respeito a: percepção e preocupação relacionadas às alterações de voz de seus filhos, fatores que influem na qualidade vocal, atitudes tomadas frente às alterações de voz, percepção de problemas vocais e referência de queixas vocais pelos filhos, importância da voz na vida familiar, escolar e para o futuro do filho. Participaram do estudo 526 pais de crianças, com idade entre 5 e 12 anos, sendo 50,2% do sexo feminino, que freqüentam escolas da rede municipal e estadual da cidade de Garça, São Paulo. Os pais responderam a um questionário padronizado. Os resultados mostraram que 74% dos pais caracterizaram a voz de seus filhos como normal e/ou bonita, sendo que 26% percebem algum tipo de desvio, entre eles muito alta, alterada, nasal e rouca ; os pais referiram que 37,5 a 68% das crianças apresentam eventualmente alguma alteração na voz e 45% dos pais se preocupam com tais alterações. A maioria dos pais que percebem alterações na voz do filho (68%) tomam alguma atitude, 36% dos pais acreditam que as crianças não percebem quando têm alterações na voz, 77,5 a 92% dos pais referiram que o filho nunca relatou queixas vocais. Grande parte dos pais (80 a 95,8%) apontou que o filho nunca apresentou mudanças na voz no decorrer do dia, perda total da voz ou rouquidão, 44% dos pais responderam que a criança se sente incomodada quando tem alguma alteração na voz e relacionam a alteração com o abuso vocal, 79,5 a 49,5% afirmaram que a voz é muito importante para a vida pessoal, familiar, escolar e para o futuro do filho.

The aim of this work was to assess the parent's opinion about their child voice regarding factors that influence in vocal quality, perception and worries about the children voice modification. Moreover, perception and attitude taken for the parents facing their child voice alteration and finally, the parent's perception of the importance of their child voice for familiar and scholar life and for the child future. Participated in this study, five hundred and twenty-six parents of children with age between 5 and 12 years. 50,2% of them were female,that frequent private and public schools in the city of Garça, state of São Paulo. The parents answered a standard questionnaire. As a result of this study we had 74% of the parents caracterized the children's voice as normal and/or beautiful, 26% perceived any kind of deviation like very high, altered, nasal and hoarse. The parents also refered that 37,5% to 68% eventually has any voice disorder and 45% of the parents are worried about that disorders. The majority of the parents that perceive the child voice disorder (68%) take any attitude; 36% of the parents believe that children do not believe that children do not perceive when they have voice disturbances; 77,5% to 92% of the parents refered that the child has no voice complaint. Several parents (80 to 95,85%) reported that the child has never had voice changes in the course of the day, total lost of the voice or hoarseness; 44% answered that the child gets unquiet when has some voice disturbance and associate the disturbance with the vocal abuse; 79,5% to 49,5% affirmed that the voice is very important to the personal life, familiar, scholar and to the child future...
