Fluency shaping with surface electromyography: a pilot study

TEMA: utilização de recursos tecnológicos para promoção da fluência. OBJETIVO: verificar a efetividade de um tratamento para gagueira baseado exclusivamente no uso da eletromiografia de superfície (EMGS). MÉTODO: participaram desse estudo quatro adultos gagos de ambos os sexos. A avaliação pré e pós-tratamento consistiu de uma sessão para coleta de amostra de fala, análise da tensão muscular de repouso e do tempo de reação para fala. O tratamento consistiu de 12 sessões de 20 minutos, monitoradas pela EMGS. RESULTADOS: observou-se redução estatisticamente significante das disfluências gagas e comuns. Os demais parâmetros, bem como a variação dos dados eletromiográficos, não apresentaram variação estatisticamente significante. CONCLUSÃO: a EMGS mostrou-se eficaz na redução da gagueira, sem a necessidade de associação com outras técnicas de promoção da fluência.BACKGROUND: the use of a technological resource in fluency promotion. AIM: to verify the effectiveness of a stuttering treatment based on the use of surface electromyography (SEMG) exclusively. METHOD: participants were four stuttering adults of both genders. Assessment, pre and post-treatment, consisted of a speech gathering session and the analyses of the rest tension and of the reaction time for speech. Treatment consisted of twelve twenty minute training sessions monitored by SEMG. RESULTS: there was a statistically significant reduction in the number of stuttering-like disfluencies (p = 0.094) and in the number of other disfluencies (p = 0.014). The other parameters, as well as differences in the electromyographic measurements, did not present significant variation. CONCLUSION: SEMG proved to be effective in the reduction of stuttering, with no need of association to other techniques

Quality of life of individuals with persistent developmental stuttering

TEMA: qualidade de vida. OBJETIVO: conhecer a influência da habilidade de fala - quanto as reações afetivas, comportamentais e cognitivas - sobre a qualidade de vida de indivíduos fluentes e com gagueira persistente do desenvolvimento (GPD). MÉTODO: 40 indivíduos adultos divididos em dois grupos, pareados por gênero e idade. O grupo de pesquisa (GI) foi composto por 20 indivíduos com PDS, sem qualquer outro déficit associado. O grupo controle (GII) foi composto por 20 indivíduos fluentes. Todos os participantes responderam ao Protocolo de Auto-Avaliação - versão para adultos. O protocolo é composto por três sessões de temáticas, cada uma delas com cinco questões, sendo que cada pergunta pode ser respondida numa escala de 1 (discordo plenamente) a 7 (concordo plenamente). A primeira sessão corresponde aos componentes afetivos, a segunda aos componentes comportamentais e a terceira aos componentes cognitivos. Todos os participantes responderam a todas as 15 questões. RESULTADOS: os achados indicaram que existe diferença na percepção da fala e da fluência entre indivíduos fluentes e com PDS. No grupo de indivíduos com PDS os diferentes graus de gravidade da patologia não identificaram pontos de divergência, ao contrário, mesmo os indivíduos com PDS leve apresentaram o mesmo perfil afetivo, comportamental e cognitivo que os indivíduos com maior comprometimento da fluência da fala. CONCLUSÃO: pelos resultados do estudo foi observado que a experiência com a gagueira diferencia os indivíduos em termos das características observáveis de fala, das dificuldades funcionais de comunicação vivida pelo falante no seu dia a dia gerando impacto negativo na qualidade de vida do indivíduo.BACKGROUND: quality of life. AIM: to verify the influence of the readiness of speech - regarding affective, behavioral and cognitive reactions - over the life quality of fluent individuals and those with persistent developmental stuttering (PDS). METHOD: 40 adults divided in two groups, paired by gender and age. The research group (GI) consisted of 20 individuals with PDS, with no other associated deficit. The research group (GII) consisted of 20 fluent individuals. All of the participants answered a Self-Assessment Protocol - version for adults. This protocol is composed by three thematic sessions, each one presenting five questions. Each question should be answered by choosing a number on a scale that varies from 1 (completely disagree) to 7 (completely agree). The first session corresponds to the affective reactions, the second to the behavioral reactions and the third to the cognitive reactions. All of the participants answered all of the 15 questions. RESULTS: the findings indicate that a difference in the perception of speech and speech fluency exists between fluent individuals and individuals with PDS. For the individuals with PDS, the different stuttering severity levels did not present divergent points; on the contrary, even the individuals with mild PDS presented the same affective, behavioral and cognitive profiles of those with a more severe stuttering. CONCLUSION: the results indicate that the experience with stuttering is different among the individuals in terms of the observable speech characteristics, functional communication difficulties experienced by the individual in everyday situations, having a negative impact in the quality of life

Language therapy and autism: results of three different models

TEMA: as dificuldades de comunicação e linguagem são elementos essenciais dos distúrbios do espectro autista, fazendo parte da tríade de sintomas utilizada para o diagnóstico. OBJETIVO: verificar a existência de diferenças observáveis a partir das características do perfil funcional da comunicação e do desempenho sócio-cognitivo de crianças e adolescentes do espectro autístico, atendidos em três diferentes situações terapêuticas, tanto no que diz respeito a um período experimental pré-determinado de intervenção, quanto na manutenção dos resultados obtidos após um igual período de tempo de atendimento fonoaudiológico regular. MÉTODO: os sujeitos foram crianças e adolescentes com diagnósticos psiquiátricos incluídos no espectro autístico em início de processos de terapia fonoaudiológica. Os participantes foram divididos em três grupos de acordo com o desenho terapêutico oferecido por um período de seis meses. RESULTADOS: não indicaram diferenças estatisticamente significativas, embora observáveis. O grupo com mais indicadores de progresso durante o período específico de intervenção diferenciada, foi o grupo A, em que os sujeitos eram atendidos em duplas. O resultado não previsto foi que não só em nenhum dos grupos foi observada diminuição dos índices obtidos, após um período de seis meses, como em algumas situações o número de sujeitos com progresso aumentou após esse período. CONCLUSÃO: os resultados do presente estudo reiteram a adequação de procedimentos de determinação do perfil individual de habilidades e inabilidades de cada sujeito como fundamentação para definições a respeito do modelo de intervenção adotado.BACKGROUND: language and communication disorders are essential features of the autistic spectrum disorders, and are part of the diagnostic criteria. AIM: to verify the existence of observable differences in the functional communicative profile and in the social cognitive performance of autistic children and adolescents receiving language therapy in three different situations. Assessment focused on the period of modified intervention and on the following period. METHOD: subjects were children and adolescents with psychiatric diagnosis within the autistic spectrum. Participants were divided in three groups according to the intervention received during a period of six months. RESULTS: determined observable differences, but not statistically significant. The group that presented the most progress was the one in which the subjects received therapy in pairs. The fact that none of groups presented a decrease in their progress indicators, as well as the fact that in a few situations the number of subjects who presented progress increased after this period was not expected. CONCLUSION: the results of the present study reinforce that the procedures used to determine the individual abilities and inabilities were useful in planning the intervention procedures.CNP

Orofacial myofunctional characterization in Parry-Romberg syndrome

Objetivo: Caracterizar os aspectos miofuncionais orofaciais de pacientes acometidos pela síndrome de Parry-Romberg, por meio de protocolos clínicos padronizados e da Eletromiografia de Superfície (EMGs) dos músculos mastigatórios. Métodos: A amostra foi composta por quatro pacientes com síndrome de Parry-Romberg e quatro indivíduos normais, separados em Grupo Pesquisa (GP) e Grupo Controle (GC), respectivamente, pareados por gênero e idade. Os grupos foram comparados em relação ao desempenho na avaliação clínica fonoaudiológica - Protocolo de Avaliação Miofuncional Orofacial com Escores Expandido (AMIOFE-E), registro das medidas de antropometria facial e de movimentos mandibulares e na avaliação instrumental - Eletromiografia de Superfície (EMGs) dos músculos mastigatórios. Para todas as comparações, foi utilizado o nível de significância de 5%. Resultados: Observou-se diferença significativa entre os grupos nas variáveis postura/posição e escore total do AMIOFE-E. Além disso, a análise das variáveis categóricas do AMIOFE-E indicou diferença significativa entre os grupos para palato - altura e largura - e comportamento da língua na deglutição e função mastigatória. A análise das medidas antropométricas indicou diferença significativa entre os grupos somente para e lateralidade mandibular à direita. Não foram observadas diferenças para os dados eletromiográficos. Conclusão: O presente estudo é o primeiro a avaliar o Sistema Miofuncional Orofacial de indivíduos acometidos pela síndrome de Parry-Romberg, por meio de protocolos padronizados. Os resultados indicam que esses indivíduos apresentam alterações, principalmente quanto à mobilidade mandibular e mobilidade de língua, na deglutição e na função de mastigação.Purpose: To characterize the orofacial miofunctional aspects of patients with Parry-Romberg syndrome, using standardized clinical protocols and Surface Electromyography (sEMG) of the masticatory muscles. Methods: Participants were four patients with Parry-Romberg syndro¬me and four healthy individuals, paired by age and gender, divided in two groups: Study Group (SG) and Control Group (CG), respectively. The groups were compared regarding performance during clinical examination - Orofacial Myofunctional Evaluation with Expanded Scores (OMES-E) and record of facial anthropometric measures and of jaw movements, and during an instrumental evaluation - Surface Elec¬tromyography (sEMG) of the masticatory muscles. Results: Statistically significant differences between the groups were observed for the follo¬wing variables: 1) numerical: mandibular lateral movement to the right, OMES-E posture/position and total score, 2) categorical: palate, behavior of the tongue during swallowing and chewing function. At sEMG no statistically significant differences were observed. Conclusion: The pre¬sent study is the first to evaluate the orofacial myofunctional system of individuals with Parry-Romberg syndrome using standardized protocols. Results indicate that these individuals present alterations specially when considering mandibular movements, tongue mobility during swallowing and chewing function

Oral motor and electromyographic characterization of adults with facial fractures: a comparison between different fracture severities

OBJECTIVES: To characterize the oral motor system of adults with facial injuries and to compare the oral motor performance/function between two different groups. METHODS: An observational, descriptive, cross-sectional study was conducted in 38 patients presenting with facial trauma who were assigned to the Division of Orofacial Myology of a Brazilian School Hospital. Patients were divided into two groups: Group 1 (G1) consisted of 19 patients who were submitted to open reduction of at least one facial fracture, and Group 2 (G2) consisted of 19 individuals who were submitted to closed fracture reduction with maxillomandibular fixation. For comparison purposes, a group of 19 healthy volunteers was recruited. All participants underwent a clinical assessment that included an oral motor evaluation, assessment of the mandibular range of motions, and electromyographic assessment of the masticatory muscles. RESULTS: Clinical assessment of the oral motor organs indicated that G1 and G2 presented deficits related to the posture, position, and mobility of the oral motor organs. Patients also presented limited mandibular ranges of movement. Deficits were greater for individuals in G1, especially for maximal incisor opening. Additionally, patients in G1 and G2 presented a similar electromyographic profile of the masticatory muscles (i.e., patients with facial fractures presented lower overall muscle activity and significant asymmetrical activity of the masseter muscle during maximum voluntary teeth clenching). CONCLUSION: Patients in G1 and G2 presented similar functional deficits after fracture treatment. The severity of facial fractures did not influence muscle function/performance 4 months after the correction of fractures

Evaluation of oral-motor movements and facial mimic in patients with head and neck burns by a public service in Brazil

OBJECTIVES: The purpose of this study was to analyze the characteristics of oral-motor movements and facial mimic in patients with head and neck burns. METHODS: An observational descriptive cross-sectional study was conducted with patients who suffered burns to the head and neck and who were referred to the Division of Orofacial Myology of a public hospital for assessment and rehabilitation. Only patients presenting deep partial-thickness and full-thickness burns to areas of the face and neck were included in the study. Patients underwent clinical assessment that involved an oral-motor evaluation, mandibular range of movement assessment, and facial mimic assessment. Patients were divided into two groups: G1 - patients with deep partial-thickness burns; G2 - patients with full-thickness burns. RESULTS: Our final study sample comprised 40 patients: G1 with 19 individuals and G2 with 21 individuals. The overall scores obtained in the clinical assessment of oral-motor organs indicated that patients with both second- and third-degree burns presented deficits related to posture, position and mobility of the oral-motor organs. Considering facial mimic, groups significantly differed when performing voluntary facial movements. Patients also presented limited maximal incisor opening. Deficits were greater for individuals in G2 in all assessments. CONCLUSION: Patients with head and neck burns present significant deficits related to posture, position and mobility of the oral myofunctional structures, including facial movements

Electromyographic and ultrasonographic assessment of the masseter muscle in normal individuals: a pilot study

TEMA: estudos recentes utilizaram a ultrassonografia com o objetivo de medir cortes musculares. OBJETIVO: caracterizar o controle motor e a morfologia do músculo masseter em indivíduos normais, verificando a compatibilidade entre a eletromiografia de superfície e a ultrassonografia. MÉTODO: cinco indivíduos adultos, sem alterações no sistema estomatognático. Os procedimentos adotados para a avaliação dos participantes foram: 1. Eletromiografia de Superfície; 2. Ultrassonografia. RESULTADOS: houve alta correlação apenas para a comparação entre hemifaces direita e esquerda no exame de ultrassonografia (repouso 0,95; máxima intercuspidação dentária 0,86). CONCLUSÃO: os resultados indicam não haver correlação entre os métodos testados, sugerindo que os exames são complementares e não excludentes.BACKGROUND: recent studies have used ultrasonography with the purpose of measuring muscle cuts. AIM: to characterize the motor control and the morphology of the masseter muscle in normal individuals, verifying the compatibility between surface electromyography and ultrasonography. METHOD: five adult individuals, with no alterations of the stomatognathic system. The adopted assessment procedures for all participants were: 1. Surface Electromyography; 2. Ultrasonography. RESULTS: a high correlation was observed only when comparing both hemifaces in the ultrasonographic assessment (rest 0.95; biting 0.86). CONCLUSION: the results indicate that there is no correlation between the tested methods, suggesting that both methods are complementary and not mutually excludent

Clinical dysphagia risk predictors after prolonged orotracheal intubation

OBJECTIVES: To elucidate independent risk factors for dysphagia after prolonged orotracheal intubation. METHODS: The participants were 148 consecutive patients who underwent clinical bedside swallowing assessments from September 2009 to September 2011. All patients had received prolonged orotracheal intubations and were admitted to one of several intensive care units of a large Brazilian school hospital. The correlations between the conducted water swallow test results and dysphagia risk levels were analyzed for statistical significance. RESULTS: Of the 148 patients included in the study, 91 were male and 57 were female (mean age, 53.64 years). The univariate analysis results indicated that specific variables, including extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking, and other signs, were possible significant high-risk indicators of dysphagia onset. The multivariate analysis results indicated that cervical auscultation and coughing were independent predictive variables for high dysphagia risk. CONCLUSIONS: Patients displaying extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking and other signs should benefit from early swallowing evaluations. Additionally, early post-extubation dysfunction recognition is paramount in reducing the morbidity rate in this high-risk population
