ABSTRACT

PURPOSE: To assess the performance of the phonatory deviation diagram and its measurements in monitoring voice quality before and after voice exercise in individuals with Parkinson's Disease. METHODS: Retrospective and documentary study. A sample of 30 subjects was used, 50% male, with a mean age of 62.13 ± 9.05 years. The results of the phonatory deviation diagram were analyzed, in the moments before and after vocal exercise with the pushing technique associated with plosive sounds, considering the area, density, shape and location of the diagram in the quadrants. For comparison purposes, the acoustic parameters of jitter, shimmer, glottal to noise excitation ratio and results of the auditory-perceptual analysis, carried out in previous research, were also considered, in the pre- and post-technical moments. RESULTS: Despite the fact that there was no difference in the distribution of samples in the diagram, after performing the vocal technique, a change in the displacement of the diagram towards the area of normality was identified in the visual qualitative analysis, and there was an association between the general degree of vocal deviation in the analysis auditory perception and the area of the diagram. There was an improvement in the shimmer values after the vocal technique. CONCLUSION: The displacement of the phonatory deviation diagram towards the area of normality corroborated the results in relation to the general degree of dysphonia, evaluated by the auditory-perceptual analysis and the shimmer results, after the vocal technique. Thus, the diagram shows good performance in monitoring voice quality of individuals with Parkinson's.


OBJETIVO: Verificar o desempenho do diagrama de desvio fonatório e de suas medidas no monitoramento da qualidade da voz, pré e pós exercício vocal, em indivíduos com Doença de Parkinson. MÉTODO: Estudo retrospectivo e documental. Utilizou-se uma amostra de 30 sujeitos, sendo 50% do sexo masculino, com média de idade de 62,13 ± 9,05 anos. Foram analisados os resultados do diagrama de desvio fonatório, nos momentos pré e pós exercício vocal com a técnica de empuxo associada aos sons plosivos, considerando-se a área, densidade, forma e localização do diagrama nos quadrantes. Para fins de comparação, os parâmetros acústicos de jitter, shimmer, glottal to noise excitation ratio e resultados da análise perceptivo-auditiva, realizada em pesquisa anterior, também foram considerados, nos momentos pré e pós-técnica. RESULTADOS: A despeito de não ocorrer diferença na distribuição das amostras no diagrama, após realização da técnica vocal, foi identificada, na análise qualitativa visual, mudança no deslocamento do diagrama em direção à área de normalidade e houve associação entre o grau geral do desvio vocal da análise perceptivoauditiva e a área do diagrama. Houve melhora nos valores de shimmer, após a técnica vocal. CONCLUSÃO: O deslocamento do diagrama de desvio fonatório em direção à área de normalidade corroborou os resultados em relação ao grau geral de disfonia avaliado pela análise perceptivoauditiva e os resultados de shimmer, após a técnica vocal empregada. Desse modo, o diagrama de desvio fonatório apresentou bom desempenho no monitoramento da qualidade vocal de indivíduos com Parkinson.

ABSTRACT

PURPOSE: To analyze the effects of lingual frenotomy on the breastfeeding of infants, based on the electrical activity of the masseter and suprahyoid muscles and assessment of the breastfeeding. METHODS: Observational study developed between October 2017 and June 2018 with a sample of 20 newborns and infants who attended a dental clinic and were diagnosed with ankyloglossia. Another 20 were excluded for meeting some of the following exclusion criteria: babies more than 6 months old, who were not on exclusive or mixed breastfeeding, who had other clinical impairments that interfered with breastfeeding, who had other foods introduced into their diet, who had neurological changes and/or craniofacial deformities, and/or who did not finish all the stages of the study. Breastfeeding was assessed with the UNICEF Breastfeeding Assessment and Observation Protocol, while the muscle electrical activity was assessed with the Electrical Activity Assessment Protocol for the Masseter and Suprahyoid Muscles in Newborns During Breastfeeding. The same speech-language-hearing therapist conducted the two assessments both before the conventional frenotomy and 7 days after it. RESULTS: The signs suggestive of breastfeeding difficulties changed 7 days after the surgery, with a p-value ≤ 0.002 for general observation of the mother, position of the infant, latch, and sucking. The maximum voluntary contraction of the masseter was the only integral parameter with a difference, as the electrical activity had decreased. CONCLUSION: Behaviors favorable to breastfeeding increased 7 days after the frenotomy in all the breastfeeding assessment categories, whereas the electrical activity of the masseter decreased.

ABSTRACT

PURPOSE: to verify whether there are differences in acoustic measures and oropharyngeal geometry between healthy individuals and people with Parkinson's disease, according to age and sex, and to investigate whether there are correlations between oropharyngeal geometry measures in this population. METHODS: 40 individuals participated, 20 with a diagnosis of Parkinson's disease and 20 healthy individuals, matched by age, sex, and body mass index. Acoustic variables included fundamental frequency, jitter, shimmer, glottal-to-noise excitation ratio, noise, and mean intensity. Oropharyngeal geometry variables were measured with acoustic pharyngometry. RESULTS: geometry variables were smaller in the group with Parkinson's disease, and older adults with Parkinson's disease had a smaller oropharyngeal junction area than healthy older adults. Regarding acoustic parameters of voice, fundamental frequency values were lower in males with Parkinson's disease, and jitter values ​​were higher in the non-elderly subjects with Parkinson's disease. There was a moderate positive correlation between oral cavity length and volume, pharyngeal cavity length and vocal tract length, and pharyngeal cavity volume and vocal tract volume. CONCLUSION: individuals with Parkinson's disease had smaller glottal areas and oropharyngeal junction areas than healthy individuals. When distributed into sex and age groups, the fundamental frequency was lower in males with Parkinson's disease. There was a moderate positive correlation between oropharyngeal length and volume measures in the study sample.

ABSTRACT

Childhood obesity is a significant public health problem. Studies show that obese children are more likely to become obese adults. In an attempt to ascertain the factors associated with childhood obesity, research has shown that this condition is associated with changes in food consumption and masticatory performance. The aim of this study was thus to evaluate food consumption and masticatory performance in normal weight, overweight and obese children aged 7 - 12 years. A cross-sectional study was carried out with 92 children aged 7 - 12 years, of both sexes, from a public school in a Brazilian municipality. The children were divided into the following groups: normal weight (n = 48), overweight (n = 26) and obese (n = 18). Anthropometric parameters, food consumption, food consistency preference, and masticatory performance were evaluated. Pearson's chi-square test was used to compare categorical variables. To compare numerical variables, the one-way ANOVA test was applied. For variables not conforming to a normal distribution, the Kruskal-Wallis test was used. The level of statistical significance was set at p ≤ 0.05. Our results show that the children with obesity consumed fewer fresh foods (median = 3, IQI = 4.00-2.00, p = 0.026), consumed more ultra-processed foods (median = 4, IQI = 4.00-2.00, p = 0.011), performed fewer mastication sequences (median = 2, IQI = 3.00-2.00, p = 0.007), and ate faster (median = 58.50, IQI = 69.00-48.00, p = 0.026) compared to children of normal weight. We conclude that children with obesity exhibit differences in food consumption and masticatory performance compared to children of normal weight.

ABSTRACT

ABSTRACT Purpose: to conduct a scoping review to identify procedures to obtain and analyze ultrasound images related to swallowing in adults and older adults. Methods: the strategy (participants, concept, and context) was employed to determine inclusion criteria - population (adults and older adults), concept (ultrasound assessment), and context (assessment of swallowing). The review will analyze observational, experimental and/or quasi-experimental, descriptive, analytical, and qualitative studies, and opinion texts and articles. It will exclude studies unavailable in full text, in animals, or in vitro, letters to the editor, errata, study protocols, and studies using ultrasound with purposes other than swallowing. There will be no restriction on the language. Two independent professionals will select the studies in the databases (MEDLINE, EMBASE, LILACS, Web of Science, and Scopus). The review will analyze the year of publication, study design, sample, age, and procedures to assess swallowing with ultrasound. Data will be presented in diagrams, tables, and narrative. Final Considerations: the literature has described ultrasound as an assessment instrument to analyze biomechanical swallowing movements. This scoping review will describe methods to acquire ultrasound images to assess swallowing.

ABSTRACT

RESUMO Vários estudos mostram a importância da avaliação quantitativa na patência nasal e do estado funcional das vias aéreas superiores para fornecer informações clínicas e diagnósticas em indivíduos respiradores orais, as quais são de grande interesse para a fonoaudiologia. O objetivo deste estudo foi avaliar o efeito da irrigação de solução salina nasal nas vias aéreas superiores através da aeração nasal e rinomanometria anterior ativa em crianças respiradoras orais. Estudo de série de oito casos, realizado em crianças com idades entre 7 e 10 anos, com diagnóstico clínico otorrinolaringológico de respiração oral. O estudo consistiu em três etapas: avaliação inicial; intervenção e avaliação final. Foram aplicados os questionários do Índice de Identificação dos Sinais e Sintomas da Respiração Oral e qualidade de vida específica para doenças em pacientes pediátricos com queixas sinonasais. Realizaram-se as avaliações da aeração nasal e o exame da rinomanometria anterior ativa. A intervenção foi realizada por meio da irrigação de solução salina nasal com 10 ml. Em seguida, os pacientes foram reavaliados pela avaliação da aeração nasal e rinomanometria, para comparar os resultados. Em relação à avaliação da aeração nasal e rinomanometria, das 16 medidas comparativas entre pré e pós-irrigação nasal, constataram-se mudanças significativas na aeração nasal e na resistência nasal. A irrigação nasal resultou em melhora nas medidas da aeração nasal, enquanto para o fluxo nasal da rinomanometria, as medidas permaneceram inalteradas entre pré e pós-irrigação nasal.


ABSTRACT Several studies have shown the importance of quantitative assessment in nasal patency and functional status of the upper airways to provide clinical and diagnostic information in oral breather individuals, which are of great interest to speech therapy. The aim of the study was to evaluate the effect of nasal saline solution irrigation on the upper airways through nasal aeration and active anterior rhinomanometry in oral breathing children. This was an eight case series study, carried out in children aged 7 to 10 years with an otorhinolaryngological clinical diagnosis of mouth breathing. The study consisted of three stages: (I) initial evaluation; (II) intervention; and (III) final evaluation. The questionnaires of the Index for the Identification of Oral Breathing Signs and Symptoms and disease-specific quality of life in pediatric patients with sinonasal complaints were applied, nasal aeration assessments and the anterior active rhinomanometry exam were carried out. The intervention was performed by irrigating nasal saline solution with 10ml. Afterwards, they were re-evaluated by nasal aeration evaluation and rhinomanometry to compare the results. Regarding nasal aeration and rhinomanometry evaluation, from the 16 comparative measurements between pre and post nasal irrigation, we obtained significant changes in nasal aeration and nasal resistance. Nasal irrigation resulted in improvement in nasal aeration measurements while nasal flow measurements from rhinomanometry remained unchanged considering pre and post nasal irrigation.

ABSTRACT Purpose To analyze the effects of lingual frenotomy on the breastfeeding of infants, based on the electrical activity of the masseter and suprahyoid muscles and assessment of the breastfeeding. Methods Observational study developed between October 2017 and June 2018 with a sample of 20 newborns and infants who attended a dental clinic and were diagnosed with ankyloglossia. Another 20 were excluded for meeting some of the following exclusion criteria: babies more than 6 months old, who were not on exclusive or mixed breastfeeding, who had other clinical impairments that interfered with breastfeeding, who had other foods introduced into their diet, who had neurological changes and/or craniofacial deformities, and/or who did not finish all the stages of the study. Breastfeeding was assessed with the UNICEF Breastfeeding Assessment and Observation Protocol, while the muscle electrical activity was assessed with the Electrical Activity Assessment Protocol for the Masseter and Suprahyoid Muscles in Newborns During Breastfeeding. The same speech-language-hearing therapist conducted the two assessments both before the conventional frenotomy and 7 days after it. Results The signs suggestive of breastfeeding difficulties changed 7 days after the surgery, with a p-value ≤ 0.002 for general observation of the mother, position of the infant, latch, and sucking. The maximum voluntary contraction of the masseter was the only integral parameter with a difference, as the electrical activity had decreased. Conclusion Behaviors favorable to breastfeeding increased 7 days after the frenotomy in all the breastfeeding assessment categories, whereas the electrical activity of the masseter decreased.

ABSTRACT

RESUMO Objetivo Verificar o desempenho do diagrama de desvio fonatório e de suas medidas no monitoramento da qualidade da voz, pré e pós exercício vocal, em indivíduos com Doença de Parkinson. Método Estudo retrospectivo e documental. Utilizou-se uma amostra de 30 sujeitos, sendo 50% do sexo masculino, com média de idade de 62,13 ± 9,05 anos. Foram analisados os resultados do diagrama de desvio fonatório, nos momentos pré e pós exercício vocal com a técnica de empuxo associada aos sons plosivos, considerando-se a área, densidade, forma e localização do diagrama nos quadrantes. Para fins de comparação, os parâmetros acústicos de jitter, shimmer, glottal to noise excitation ratio e resultados da análise perceptivo-auditiva, realizada em pesquisa anterior, também foram considerados, nos momentos pré e pós-técnica. Resultados A despeito de não ocorrer diferença na distribuição das amostras no diagrama, após realização da técnica vocal, foi identificada, na análise qualitativa visual, mudança no deslocamento do diagrama em direção à área de normalidade e houve associação entre o grau geral do desvio vocal da análise perceptivoauditiva e a área do diagrama. Houve melhora nos valores de shimmer, após a técnica vocal. Conclusão O deslocamento do diagrama de desvio fonatório em direção à área de normalidade corroborou os resultados em relação ao grau geral de disfonia avaliado pela análise perceptivoauditiva e os resultados de shimmer, após a técnica vocal empregada. Desse modo, o diagrama de desvio fonatório apresentou bom desempenho no monitoramento da qualidade vocal de indivíduos com Parkinson.


ABSTRACT Purpose To assess the performance of the phonatory deviation diagram and its measurements in monitoring voice quality before and after voice exercise in individuals with Parkinson's Disease. Methods Retrospective and documentary study. A sample of 30 subjects was used, 50% male, with a mean age of 62.13 ± 9.05 years. The results of the phonatory deviation diagram were analyzed, in the moments before and after vocal exercise with the pushing technique associated with plosive sounds, considering the area, density, shape and location of the diagram in the quadrants. For comparison purposes, the acoustic parameters of jitter, shimmer, glottal to noise excitation ratio and results of the auditory-perceptual analysis, carried out in previous research, were also considered, in the pre- and post-technical moments. Results Despite the fact that there was no difference in the distribution of samples in the diagram, after performing the vocal technique, a change in the displacement of the diagram towards the area of normality was identified in the visual qualitative analysis, and there was an association between the general degree of vocal deviation in the analysis auditory perception and the area of the diagram. There was an improvement in the shimmer values after the vocal technique. Conclusion The displacement of the phonatory deviation diagram towards the area of normality corroborated the results in relation to the general degree of dysphonia, evaluated by the auditory-perceptual analysis and the shimmer results, after the vocal technique. Thus, the diagram shows good performance in monitoring voice quality of individuals with Parkinson's.

ABSTRACT

OBJECTIVE: To verify possible correlations between formant and cepstral parameters and oropharyngeal geometry in singers, stratified by sex. METHOD: Voice records and oropharyngeal measures of 31 singers - 13 females and 18 males, mean age of 28 (±5.0) years - were retrieved from a database and analyzed. The oropharyngeal geometry measures were collected with acoustic pharyngometry, and the voice records consisted of sustained vowel /Ԑ/ phonation, which were exported to Praat software and edited to obtain the formant and cepstral parameters, stratified by sex. The Pearson linear correlation test was applied to relate voice parameters to oropharyngeal geometry, at the 5% significance level; the linear regression test was used to justify the variable related to the second formant. RESULTS: Differences between the sexes were identified only in the oral cavity length (greater in males) and pharyngeal cavity length (greater in females). There was a linear correlation between the third formant and the cepstrum in the female group. In the male group, there was a linear correlation between the cepstrum and the third and fourth formants. A positive linear correlation with up to 95% confidence was also identified between the pharyngeal cavity volume and the second formant in the female group, making it possible to estimate a regression model for the second formant (R2 = 0.70). CONCLUSION: There are correlations between the oropharyngeal geometry and formant and cepstral parameters in relation to sex. The pharyngeal cavity volume showed the greatest correlation between females and the second formant.

ABSTRACT

INTRODUCTION: Patients undergoing maxillectomies may present alterations in the stomatognathic functions involved in oral communication. Rehabilitative treatment should favor the rescue of these functions, through surgical flaps, obturator prostheses or both. OBJECTIVES: The present study aims to present the impact of the use of the palatal obturator on the oropharyngeal geometry and on the voice of patients undergoing maxillectomies, after adaptation to trans-surgical palatine obturators (TPO). METHODS: Twelve patients treated at a Cancer Hospital, submitted to maxillectomy and rehabilitated during surgery were evaluated. The oropharyngeal geometry was measured by acoustic pharyngometry and the vocal parameters were evaluated through auditory-perceptual and acoustic analyses. The comparison between the results with and without TPO was analyzed using the Wilcoxon test and the correlation between oropharyngeal measurements and acoustic parameters using Spearman's correlation coefficient, all with a significance level of 5%. RESULTS: There was a decrease in the following oropharyngeal measurements with the use of TPO: length of the pharyngeal cavity and vocal tract, volume of the oral cavity, pharyngeal and vocal tract and area of ​​the oropharyngeal junction. There was no difference in the length of the oral cavity and in the glottic area between situations with and without TPO. In the vocal evaluation, changes in intelligibility and resonance were observed in the situation without TPO and, in only one case, mild hypernasality was detected in the situation with TPO. CONCLUSIONS: It is concluded that the use of TPO brought the oropharyngeal measurements closer to normal values ​​and provided an improvement in speech intelligibility and vocal resonance in maxilectomized individuals.

ABSTRACT

OBJECTIVE: To verify whether the dimensions of different segments of the oropharyngeal cavity have different proportions between Parkinson's disease patients and vocally healthy subjects and investigate whether the measurements of these subjects' oropharyngeal geometry associate with their acoustic measurements of voice. METHOD: Quantitative, descriptive, cross-sectional, and retrospective study with secondary data, approved by the Human Research Ethics Committee under no. 4.325.029. We used vocal samples and data from the oropharyngeal geometry of 40 subjects - 20 with Parkinson's disease stages I to III and 20 who formed the control group, matched for sex and age. Each group had 10 males and 10 females, mean age of 61 years (±6.0). Formant (F1, F2, and F3) and cepstral measures of the sustained vowel /ε/ were extracted and arranged in the database to determine their values using Praat software. The data were descriptively analyzed, with statistics generated with R software. The proportion of oropharyngeal geometry measurements was arranged by mean values and coefficients of variation. Pearson's linear correlation test was applied to relate voice parameters to oropharyngeal geometry, considering P < 0.05, and linear regression test, to justify F2. RESULTS: The Parkinson's disease group showed a linear relationship between oral cavity length and F1 in males (P = 0.04) and between glottal area and F2 in females (P = 0.00); linear relationships were established according to age in both groups, and a regression model for F2 was estimated (R2 = 0.61). There was no difference between pathological and healthy voices; there was a difference in the proportional relationship of oropharyngeal geometry between the groups. CONCLUSION: The proportional relationship of oropharyngeal geometry differs between the Parkinson's disease group and the control group, as well as the relationship between oropharyngeal geometry and formant and cepstral values of voice according to the subjects' sex and age.

ABSTRACT

Introdução: A mastigação tem uma importância significativa para o desenvolvimento das estruturas do Sistema Estomatognático (SE), sendo esta aperfeiçoada no decorrer da vida. A eletromiografia de superfície destaca-se como uma importante ferramenta de avaliação capaz de quantificar a atividade elétrica dos músculos mastigatórios, sendo uma forma de caracterizar o comportamento dessa função estomatognática. Observando a complexidade e importância da mastigação, torna-se importante conhecer melhor as modificações desta função no decorrer dos ciclos de vida. Objetivo: O objetivo do estudo foi realizar análise eletromiográfica dos músculos da mastigação em indivíduos sem queixas orofaciais representantes dos ciclos da infância, adolescência, fase adulta e senescência. Método: A amostra foi composta por 120 voluntários de ambos os sexos, distribuídos em quatro grupos de acordo com a faixa de idade. Os voluntários foram submetidos à avaliação da mastigação por meio da eletromiografia de superfície durante o repouso, contração voluntária máxima, mastigações unilaterais direita e esquerda e mastigação habitual; bem como a verificação da força de mordida entre os dentes incisivos centrais, molares do lado direito e molares do lado esquerdo. Realizou-se, ainda, a tomada de medidas antropométricas faciais das hemifaces direta e esquerda dos voluntários. Resultados: Os resultados apontaram comportamentos morfológicos e funcionais distintos entre os grupos estudados, bem como a influência da variável sexo nas respostas eletrofisiológicas da função mastigatória. Conclusão: foi verificado que o comportamento mastigatório variou segundo a idade e o sexo, apontando uma tendência de correlação entre os componetes anatômicos e funcionais envolvidos nessa função estomatognática.


Introduction: Chewing is of significant importance for the development of the structures of the Stomatognathic System (SE), which is improved throughout life. Surface electromyography stands out as an important assessment tool capable of quantifying the electrical activity of the masticatory muscles, being a way to characterize the behavior of this stomatognathic function. Observing the complexity and importance of chewing, it is important to better understand the changes in this function during the life cycles. Objective: The objective of the study was to perform an electromyographic analysis of the muscles of mastication in individuals without orofacial complaints representing the cycles of childhood, adolescence, adulthood and senescence. Method: The sample consisted of 120 volunteers of both sexes, distributed in four groups according to the age group. The volunteers underwent chewing assessment by means of surface electromyography during rest, maximum voluntary contraction, unilateral right and left chewing and habitual chewing; as well as the verification of the bite force between the central incisor teeth, molars on the right side and molars on the left side. Facial anthropometric measurements of the direct and left hemifaces of the volunteers were also taken. Results: The results showed distinct morphological and functional behaviors between the groups studied, as well as the influence of the gender variable on the electrophysiological responses of the masticatory function. Conclusion: it was found that the masticatory behavior varied according to age and sex, pointing to a trend of correlation between the anatomical and functional components involved in this stomatognathic function.

ABSTRACT

PURPOSE: This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) associated with vocal therapy in women with behavioral dysphonia. METHOD: Seventeen women with behavioral dysphonia were divided into an experimental group (n = 8) and a placebo group (n = 9). All were submitted to six sessions of vocal therapy, according to the Comprehensive Voice Rehabilitation Program. In the experimental group, therapy was associated with TENS (30 minutes) and in the placebo group, the electrodes were placed and the equipment remained off. The vocal handicap, the voice through the acoustic and auditory perception evaluation, the electrical activity, and the superficial temperature of the suprahyoid and infrahyoid muscles were evaluated. Pre and post data were compared by parametric and nonparametric tests. RESULTS: There was a decreased in vocal handicap of the placebo group (P = 0.002) and a decreased in the percentage of electrical activity of the right (P = 0.036) and left (P = 0.017) infrahyoid muscles of the experimental group in vowel emission and sequential speech (P = 0.036). There was an increase in temperature in the right infrahyoid region in vowel emission (P = 0.027) and the temperature difference decreased quantitatively between the supra and infrahyoid regions in the experimental group. CONCLUSION: TENS associated with vocal therapy reduced the electrical activity of the infrahyoid muscles and balance the temperature between the supra- and infrahyoid regions in women with behavioral dysphonia.
