Voice Disorders in Teachers: Clinical, Videolaryngoscopical, and Vocal Aspects

Dysphonia is more prevalent in teachers than among the general population. The objective of this study was to analyze clinical, vocal, and videolaryngoscopical aspects in dysphonic teachers. Ninety dysphonic teachers were inquired about their voice, comorbidities, and work conditions. They underwent vocal auditory-perceptual evaluation (maximum phonation time and GRBASI scale), acoustic voice analysis, and videolaryngoscopy. The results were compared with a control group consisting of 90 dysphonic nonteachers, of similar gender and ages, and with professional activities excluding teaching and singing. In both groups, there were 85 women and five men (age range 31-50 years). In the controls, the majority of subjects worked in domestic activities, whereas the majority of teachers worked in primary (42.8%) and secondary school (37.7%). Teachers and controls reported, respectively: vocal abuse (76.7%; 37.8%), weekly hours of work between 21 and 40 years (72.2%; 80%), under 10 years of practice (36%; 23%), absenteeism (23%; 0%), sinonasal (66%; 20%) and gastroesophageal symptoms (44%; 22%), hoarseness (82%; 78%), throat clearing (70%; 62%), and phonatory effort (72%; 52%). In both groups, there were decreased values of maximum phonation time, impairment of the G parameter in the GRBASI scale (82%), decrease of F0 and increase of the rest of acoustic parameters. Nodules and laryngopharyngeal reflux were predominant in teachers; laryngopharyngeal reflux, polyps, and sulcus vocalis predominated in the controls. Vocal symptoms, comorbidities, and absenteeism were predominant among teachers. The vocal analyses were similar in both groups. Nodules and laryngopharyngeal reflux were predominant among teachers, whereas polyps, laryngopharyngeal reflux, and sulcus were predominant among controls.

Vocal effectiveness of speech-language pathology students: Before and after voice use during service delivery.

BackgroundAs a professional voice user, it is imperative that a speech-language pathologist's (SLP) vocal effectiveness remain consistent throughout the day. Many factors may contribute to reduced vocal effectiveness, including prolonged voice use, vocally abusive behaviours, poor vocal hygiene and environmental factors.ObjectivesTo determine the effect of service delivery on the perceptual and acoustic features of voice.MethodA quasi-experimental., pre-test–post-test research design was used. Participants included third- and final-year speech-language pathology students at the University of Pretoria (South Africa). Voice parameters were evaluated in a pre-test measurement, after which the participants provided two consecutive hours of therapy. A post-test measurement was then completed. Data analysis consisted of an instrumental analysis in which the multidimensional voice programme (MDVP) and the voice range profile (VRP) were used to measure vocal parameters and then calculate the dysphonia severity index (DSI). The GRBASI scale was used to conduct a perceptual analysis of voice quality. Data were processed using descriptive statistics to determine change in each measured parameter after service delivery.ResultsA change of clinical significance was observed in the acoustic and perceptual parameters of voice.ConclusionGuidelines for SLPs in order to maintain optimal vocal effectiveness were suggested.

Discriminant Capacity of Acoustic, Perceptual, and Vocal Self: The Effects of Vocal Demands

To analyze the discrimination ability of acoustic, auditory parameters, and perception of vocal effort during professional and social voice use, and the correlations of these parameters with the vocal demands. Longitudinal study. Seventy-three subjects participated in the study: 31 females aged from 28 to 65years (G1; professional voice users) and 42 females aged from 31 to 59years (G2, social voice users; ). All the subjects were subjected to acoustic voice analysis including F0 median, semiamplitude interquartile, quantile 99.5%, and skewness; first F0 derivate mean, standard deviation (SD), and skewness; intensity skewness; spectral slope mean, SD, and skewness; long-term average spectrum-frequency SD, perceptual parameters (GRBASI scale), and self-perception of vocal effort, before and after 2hours and 30 minutes of voice use. Statistical analyses were completed via multivariate discriminant analysis and canonical correlation analysis. Discriminant analysis of acoustic, perceptual, and self-rating variables and analysis of the grouped parameters did not differentiate the samples before and after vocal use. Higher levels of canonical correlation were found for the professional voice group after voice use, with a correlation between perceptual analysis and acoustic measures. The current measures could not discriminate the differences of the type of vocal demands, professional or social.

Auditory-perceptual analysis of voice in abused children and adolescents

IntroductionAbused children and adolescents are exposed to factors that can trigger vocal changes. ObjectiveThis study aimed to analyze the prevalence of vocal changes in abused children and adolescents, through auditory-perceptual analysis of voice and the study of the association between vocal changes, communication disorders, psychiatric disorders, and global functioning. MethodsThis was an observational and transversal study of 136 children and adolescents (mean age 10.2 years, 78 male) who were assessed by a multidisciplinary team specializing in abused populations. Speech evaluation was performed (involving the aspects of oral and written communication, as well as auditory-perceptual analysis of voice, through the GRBASI scale). Psychiatric diagnosis was performed in accordance with the DSM-IV diagnostic criteria and by applying the K-SADS; global functioning was evaluated by means of the C-GAS scale. ResultsThe prevalence of vocal change was 67.6%; of the patients with vocal changes, 92.3% had other communication disorders. Voice changes were associated with a loss of seven points in global functioning, and there was no association between vocal changes and psychiatric diagnosis. ConclusionThe prevalence of vocal change was greater than that observed in the general population, with significant associations with communication disorders and global functioning. The results demonstrate that the situations these children experience can intensify the triggering of abusive vocal behaviors and consequently, of vocal changes.

Anxiety and Depression Symptoms in Dysphonia Patients before and after Speech Therapy

Methods: It is an uncontrolled clinical trial with patients who attended voice therapy at the outpatient clinic of a hospital (southern Brazil). All the patients underwent otorhinolaryngologic assessment for laryngeal disorder diagnosis. Perceptual-auditory voice assessment (GRBASI scale) and Hospital Anxiety and Depression Scale (HADS) were applied before and after voice therapy. Mann-Whitney, Wilcoxon, and Pearson Correlation tests were carried out, maximum significance level of 5% (p ≤ 0.05), SPSS 16.0. It was approved by Ethics Committee of Institution (record 986/12).

Perceptual and acoustic parameters of vocal nodules in children

Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children. PurposeTo study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules. DesignDiagnostic test study. Patients and interventionsA comparative study was carried out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between 4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out. ResultsThere was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ, shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups. ConclusionCompromising of auditory-perceptual (G, R, B and S) and acoustic vocal parameters (jitter, PPQ, shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

Avaliação de voz e qualidade de vida após laringectomia supracricóide

OBJETIVO: Avaliar sujeitos submetidos a laringectomia supracricóide quanto à autoavaliação da voz, análises perceptivo-auditiva e acústica e impacto da alteração vocal na qualidade de vida. MÉTODOS: Estudo prospectivo, observacional, que envolveu 12 sujeitos do gênero masculino, com disfonia orgânica, média de idade de 59,3 anos, que realizaram laringectomia supracricóide para exérese de neoplasia maligna de laringe. Foi realizada análise perceptivo-auditiva, por meio da escala GRBASI em duplo-cego. A análise acústica realizada através do software VOXMETRIA® considerou parâmetros de frequência fundamental, jitter e shimmer, proporção harmônico-ruído e diagrama de desvio fonatório. A autoavaliação vocal e o estudo do impacto da disfonia na qualidade de vida dos sujeitos ocorreram por meio de aplicação dos protocolos: Qualidade de Vida em Voz (QVV) e o Índice de Desvantagem Vocal (IDV). RESULTADOS: A frequência das vozes variou entre 91,59 Hz e 260,05 Hz e as medidas de shimmer e jitter mostraram-se alteradas, comprovando as análises perceptivo-auditivas, que revelaram vozes com grau de desvio de moderado a intenso. A maioria dos sujeitos qualificou suas vozes como razoável ou boa. O QVV demonstrou escores brutos em níveis compatíveis com vozes disfônicas em 50,0%. O IDV mostrou predomínio do domínio orgânico. CONCLUSÃO: O grau de desvio vocal dos sujeitos mostrou-se entre moderado e intenso, confirmando parâmetros acústicos, enquanto que os sujeitos qualificaram suas vozes como razoáveis ou boas. Os escores do QVV e IDV revelaram predomínio de domínios físico e orgânico, respectivamente, com parte dos sujeitos com escores compatíveis a vozes disfônicas. Sugerem-se estudos que busquem aprofundar o conhecimento entre autopercepção da voz e impacto na qualidade de vida de sujeitos com disfonia decorrente de carcinoma de laringe.

Vocal Parameters and Voice-Related Quality of Life in Adult Women With and Without Ovarian Function

To identify the perceptual and acoustic parameters of voice in adult women with and without ovarian function and its impact on quality of life related to voice. Cross-sectional and analytical study with 106 women divided into, two groups: G1, with ovarian function (n=43) and G2, without physiological ovarian function (n=63). The women were instructed to sustain the vowel "a" and the sounds of /s/ and /z/ in habitual pitch and loudness. They were also asked to classify their voices and answer the voice-related quality of life (V-RQOL) questionnaire. The perceptual analysis of the vocal samples was performed by three speech-language pathologists using the GRBASI (G: grade; R: roughness; B: breathness; A: asthenia; S: strain; I: instability) scale. The acoustic analysis was carried out with the software VoxMetria 2.7h (CTS Informatica). The data were analyzed using descriptive statistics. In the perceptual analysis, both groups showed a mild deviation for the parameters roughness, strain, and instability, but only G2 showed a mild impact for the overall degree of dysphonia. The mean of fundamental frequency was significantly lower for the G2, with a difference of 17.41Hz between the two groups. There was no impact on V-RQOL in any of the V-RQOL domains for this group. With the menopause, there is a change in women's voices, impacting on some voice parameters. However, there is no direct impact on their quality of life related to voice.

Distúrbio de voz em professores: autorreferência, avaliação perceptiva da voz e das pregas vocais

OBJETIVO: Analisar a presença do distúrbio de voz em professores na concordância entre autorreferência, avaliação perceptiva da voz e das pregas vocais. MÉTODOS: Deste estudo transversal, participaram 60 professores de duas escolas públicas de ensino fundamental e médio. Após responderem questionário de autopercepção (Condição de Produção Vocal do Professor - CPV-P) para caracterização da amostra e levantamento de dados sobre autorreferência ao distúrbio de voz, foram submetidos à coleta de amostra de fala e exame nasofibrolaringoscópico. Para classificar as vozes, três juízes fonoaudiólogos utilizaram à escala GRBASI e, para pregas vocais (PPVV), um otorrinolaringologista descreveu as alterações encontradas. Os dados foram analisados descritivamente, e a seguir submetidos a testes de associação. RESULTADOS: No questionário, 63,3% dos participantes referiram ter ou ter tido distúrbio de voz. Do total, 43,3% foram diagnosticados com alteração em voz e 46,7%, em prega vocal. Não houve associação entre autorreferência e avaliação da voz, nem entre autorreferência e avaliação de PPVV, com registro de concordância baixa entre as três avaliações. Porém, houve associação entre a avaliação da voz e de PPVV, com concordância intermediária entre elas. CONCLUSÃO: Há maior autorreferência a distúrbio de voz do que o constatado pela avaliação perceptiva da voz e das pregas vocais. A concordância intermediária entre as duas avaliações prediz a necessidade da realização de pelo menos uma delas por ocasião da triagem em professores.

Idiopathic Parkinson's disease: vocal and quality of life analysis

To compare voice and life quality of male patients with idiopathic Parkinson's disease, with individuals without disease (Control Group). A cross-sectional study that evaluated the voice of individuals with Parkinson's disease, the group was composed of 27 subjects, aged from 39 to 79 years-old (average 59.96). The Control Group was matched on sex and age. Participants underwent voice recording. Perceptual evaluation was made using GRBASI scale, which considers G as the overall degree of dysphonia, R as roughness, B as breathiness, A as asthenia, S as strain and I as instability. The acoustic parameters analyzed were: fundamental frequency, jitter, shimmer, and harmonic to noise ratio (NHR). For vocal self-perception analysis, we used the Voice Related Quality of Life protocol. Fundamental frequency and jitter presented higher values in the Parkinson's group. NHR values were higher in the Control Group. Perceptual analysis showed a deviation ranging. The vocal disorder self-perception demonstrated a worse impact on quality of life. Individuals with Parkinson's disease have an altered voice quality and a negative impact on quality of life.

Análise vocal em pacientes com disfonia espasmódica nos momentos pré e pós tratamento com toxina Botulínica A

OBJETIVO: avaliar de forma objetiva e subjetiva a voz de pacientes com disfonia espasmódica nos momentos pré e pós aplicação de toxina botulínica A. MÉTODO: as emissões vocais de onze pacientes do sexo feminino foram registradas antes e após (15 dias) o tratamento. As amostras vocais foram analisadas por duas fonoaudiólogas com experiência em voz por meio da análise perceptivo-auditiva (escala GRBASI) e da análise espectrográfica. RESULTADOS: na análise perceptivo-auditiva com vogal sustentada os parâmetros que alteraram após o tratamento foram o grau de severidade, tensão e instabilidade, enquanto na fala encadeada foram o grau de severidade e a tensão. Na análise espectrográfica ocorreu melhora do traçado após o tratamento sem significância estatística entre os parâmetros. CONCLUSÃO: ocorreu melhora significante dos aspectos perceptivo-auditivos após o tratamento e, portanto, as injeções de toxina botulínica A mostraram-se eficazes no tratamento da disfonia espasmódica no grupo estudado.

Análise perceptivo-auditiva, acústica e autopercepção vocal em crianças

To establish the occurrence of dysphonic children and to relate data from auditory-perceptive, acoustic and vocal self-perception analyses of dysphonic and non-dysphonic children. Participants were 70 children, 37 female and 33 male, with ages ranging from 6 to 10 years. The sustained emission of the vowel /a/ was recorded, and children replied to the question "What do you think of your voice?".After that, the auditory-perceptive analysis of their voices was carried out, based on the parameters of the GRBASI scale. The acoustic analysis was also conducted, considering the following measures: fundamental frequency, frequency and amplitude perturbation quotient, and harmonic-to-noise ratio. The self-perception analysis of the subjects' voices was based on content analysis. Data were statistically analyzed. The occurrence of dysphonic children was 37.14%. Breathiness was the most common vocal quality among dysphonic children, followed by roughness, which was also common. The acoustic measures frequency and amplitude perturbation quotient and harmonic-to-noise ration were higher among dysphonic children. However, these measures were similar between children that had positive self-perception and those with negative self-perception. Negative self-perception was more frequent among dysphonic children. The occurrence of dysphonia in the studied group was 37.14%. Dysphonic children present negative self-perception of their voices, voice quality predominantly rough and/or breathy, and altered acoustic measures, when compared to non-dysphonic children.

Avaliação vocal e cervicoescapular em militares instrumentistas de sopro

OBJETIVO: Este estudo transversal e prospectivo objetivou avaliar qualidade vocal, respiração e região cervicoescapular em instrumentistas de sopro integrantes da Banda Musical do Exército. MÉTODOS: Foram estudados 42 sujeitos do gênero masculino, militares, com idades entre 20 e 45 anos, divididos em: Grupo Experimental, com 30 instrumentistas de sopro, e Grupo Controle, com 12 instrumentistas de percussão. Todos passaram por entrevista; avaliação vocal - registro da voz e análise perceptivo-auditiva com uso da escala GRBASI; avaliação do tipo respiratório; avaliação fisioterapêutica da região cervicoescapular - inspeção visual dos perfis anterior, lateral e posterior, palpação dos músculos trapézio fibras-superiores, esternocleidomastoídeos, escalenos e base de occipital; e testes de mobilidade cervical e de encurtamentos musculares. RESULTADOS: Não houve diferença entre Grupo Experimental e Controle quanto à presença de queixas vocais; os sujeitos do Grupo Experimental apresentaram mais sintomas laríngeos e relataram mais dor em músculo trapézio e região cervical quando comparados aos sujeitos do Controle. Os sujeitos do Grupo Experimental apresentaram maior alteração nos parâmetros vocais tensão e instabilidade do que os sujeitos do Grupo Controle. Constatou-se maior incidência da respiração costodiafragmático-abdominal no Grupo Experimental. Não houve diferença entre os grupos estudados quanto à postura, encurtamentos musculares e mobilidade cervical; porém o Grupo Experimental apresentou mais dor à palpação em músculo trapézio - fibras superiores. CONCLUSÃO: Os militares instrumentistas de sopro apresentaram alterações vocais e da musculatura cervicoescapular e necessitam de ações de promoção à saúde vocal e postural.

Acoustic and hearing-perceptual voice analysis in individuals with idiopathic Parkinson's disease in "on" and "off" stages

To evaluate the voice quality of patients with idiopathic Parkinson's disease, at the "on" and "off" moments of the disease. Five individuals with Parkinson's disease and five of the control group were assessed. All of them underwent the recording of voice and speech. The acoustic parameters analyzed were: fundamental frequency, jitter, shimmer, harmonic noise proportion and index of tremor, besides performing the hearing-perceptual analysis by means of GRBASI scale. The findings were analyzed using statistics through t test and the level of significance adopted was p < 0.05. There was no difference in the acoustic parameters in the three analyzed groups. In the hearing-perceptual analysis, patients with idiopathic Parkinson's disease showed altered voice quality and the ones from the control group, neutral vocal quality. Patients with idiopathic Parkinson's disease present rough, breathy and unstable vocal quality in both stages. In the acoustic analysis, there are no differences in the studied parameters.

Objective Vocal Quality in Children Using Cochlear Implants: A Multiparameter Approach

The purpose of this study was to determine the objective vocal quality in 36 prelingually deaf children using cochlear implant (CI) with a mean age of 9 years. An additional purpose was to compare the objective vocal quality of these 36 CI users with 25 age-matched children with prelingual severe hearing loss using conventional hearing aids (HAs) and 25 normal hearing (NH) children. The design for this cross-sectional study was a multigroup posttest-only design. The objective vocal quality was measured by means of the dysphonia severity index (DSI). Moreover, perceptual voice assessment using the GRBASI scale was performed. CI children have a vocal quality by means of the DSI of +1.8, corresponding with a DSI% of 68%, indicating a borderline vocal quality situated 2% above the limit of normality. The voice was perceptually characterized by the presence of a very slight grade of hoarseness, roughness, strained phonation, and higher pitch and intensity levels. No significant objective vocal quality differences were measured between the voices of the CI children, HA users, and NH children. According to the results, one aspect of the vocal approach in children with CI and using HAs must be focused on the improvement of the strained vocal characteristic and the use of a lower pitch and intensity level.

Medialization thyroplasty: vocal outcome of silicone and titanium implant

Unilateral vocal fold paralysis can result in incomplete glottic closure, compromising the vocal efficiency and increasing the risk of aspiration. The glottic gap can be reduced by medialization thyroplasty. Both silicone and titanium implants have been described to be efficient in the improvement of the vocal outcome. The aim of this study was to assess the vocal outcome after medialization thyroplasty using silicone and titanium implants and to compare the results of the two implanted materials using prospective sequential cohort study. 24 patients underwent medialization thyroplasty, performed under local anaesthesia with intravenous sedation: 10 patients were included in the silicone cohort and 14 in the titanium cohort. All patients underwent vocal assessment preoperatively and postoperatively, using the Voice Handicap Index, the GRBASI scale, maximum phonation time and the Dysphonia Severity Index. Postoperative analysis of the entire population showed statistically significant improvement for the Voice Handicap Index, maximum phonation time, Dysphonia Severity Index and the parameters G, B and A of the GRBASI scale (83% follow up). Subgroup analysis showed a statistically significant greater improvement of Voice Handicap Index of the titanium cohort compared with the silicone cohort. Improvement of maximum phonation time, Dysphonia Severity Index and GRBASI scale of the titanium cohort was greater than improvement of the silicone cohort, but this difference was not statistically significant. Both silicone and titanium medialization implants showed improvement of vocal outcome, the results of the titanium implant being superior.

Perceptual evaluation of pathological voice quality: A comparative analysis between the RASATI and GRBASI scales

To provide mutual understanding between different evaluation scales for pathological voice quality, comparative analyses between the GRBASI and the RASATI systems were conducted. A total of 100 voice samples were rated by experienced Brazilian and Japanese listeners. Analysis by factor analysis with varimax rotation identified significant interrelations between the scales, with asthenia, instability, and roughness as the common factors. Grade-of-hoarseness, only included in GRBASI, corresponds to a combination of roughness, breathiness, and instability. Harshness, included only in RASATI, can be predicted by breathiness with strain in the GRBASI scale. Roughness is found to be the most consistent factor and the easiest to identify by evaluators with different linguistic background.

Correlação entre dados perceptivo-auditivos e qualidade de vida em voz de idosas

vocal quality and voice-related quality of life in elderly women to assess the vocal quality and voice-related quality of life in elderly women, as well as verify if the presence of dysphonia has an influence on the life quality of these women. one hundred and three elderly women, with ages ranging from 60 to 103 years, were recruited. The V-RQOL was answered by the participants and their voices were registered and analyzed perceptually by five experienced speech pathologists, using the GRBASI scale. After the intra-rater reliability analysis, three speech pathologists were selected with whom a single GRBASI scale was built for each of the participant's voice. Later, this single assessment was compared to the physical, socio-emotional and total V-RQOL scores. most of the elderly women presented V-RQOL total scores between 70 and 100. They also presented a mild to moderate vocal disorder in the overall scores related to dysphonia, roughness, breathiness and instability in the GRBASI scale and did not present scores related to asthenia or strain. The G, R, B and I parameters of the GRBASI scale were statistically correlated to the physical and total V-RQOL scores. although most of the elderly women presented some level of dysphonia, the vocal disorders did not have an influence on their life quality. However, the physical and total V-RQOL scores were correlated to dysphonia severity, indicating that the more sever the dysphonia, the lower the voice-related quality of life.
