Respiratory-swallow coordination (RSC) is critical for safe and efficient swallowing. In healthy adults, RSC is most frequently characterized by an exhale-swallow-exhale pattern initiated within the mid-lung volume range with a respiratory pause of approximately one second. This combination in RSC behaviors is thought to be most optimal for swallowing-related bolus clearance and airway protection. Deviations from these RSC behaviors are observed at disproportionately higher rates in people with Parkinson’s disease (PD) when compared to non-dysphagic, healthy adults. However, little is known about which variables influence RSC in PD, if the RSC behaviors that are most optimal for swallowing in healthy adults are also most optimal for swallowing in PD, and if respiratory-swallow training can be used to successfully rehabilitate suboptimal RSC, swallowing safety, and swallowing efficiency in PD. This dissertation document includes a series of four studies that address these important clinical research questions. Chapter 1 will begin by reviewing the current body of literature as it relates to dysphagia in PD, RSC in healthy adults and PD, respiratory-swallow training as a skill-based treatment for dysphagia rehabilitation, and motor learning considerations for respiratory-swallow skill training in PD. Chapter 2 will be used to examine the relationships among RSC with patient- and swallowing-specific factors in PD. Chapter 2 will also be used to assess the influence of RSC behaviors on measures of swallowing safety (penetration-aspiration) and swallowing efficiency (pharyngeal residue) in PD. Chapter 3 will then evaluate the effects of verbal cueing on RSC in PD as a method of determining if RSC is stimulable for rehabilitative change. Chapter 4 will explore the effects of respiratory-swallow training on swallowing safety and efficiency rehabilitation in a person with mid-stage PD and severe dysphagia within the context of a single-subject experimental design. Chapter 5 will then examine the effects of respiratory-swallow training on dysphagia and RSC rehabilitation within the context of a cohort study. Chapter 5 will also be used to compare the effects of constant versus variable practice in order to explore how principles of motor learning can be used to enhance respiratory-swallow training outcomes. This document will then conclude by synthesizing the results from Chapters 2-5 and by discussing directions for future research.

The purpose of this study was to determine the amount, type, and content of training acquired by SLPs presently working in dysphagia management, as well as their level of involvement. A questionnaire was sent to 97 Oregon SLPs. Of these, 77 (80%) responded, and 52 met criteria. The resulting data indicated that SLPs involved with dysphagia work in a variety of settings, including hospitals, nursing homes, home health agencies, and private practice. Seventy-two percent of the subjects have been involved with dysphagia management for less than 10 years; 79% treated between 1 and 10 patients for dysphagia the month prior to filling out the questionnaire; and 81% have provided other staff in their settings with in-service on dysphagia.

Progressive disorders of airway protection, namely cough (dystussia) and swallowing (dysphagia) dysfunction, are highly prevalent in Parkinson’s disease (PD), impacting quality of life and contributing to the development of aspiration pneumonia – a leading cause of death in this population. To date, dysphagia rehabilitation has remained the primary (and often only) treatment target of choice by clinicians managing dysphagia in patients with PD and other neurodegenerative disease. This is a major concern since the progressive nature of PD makes it somewhat unreasonable to expect that treatments can fully rehabilitate swallowing dysfunction and eliminate chronic aspiration. Instead, rehabilitating cough dysfunction can serve as an adjunctive approach to promote pulmonary health. Considering that impairments in motor control and organization are primary features of PD, skill training may have a necessary role in cough rehabilitation. Despite a growing body of research supporting the feasibility and effectiveness of cough skill training, a significant gap remains in our understanding of optimal skill training parameters that maximize treatment outcomes through motor learning. This document addresses this gap in the literature in a series of three research studies. Chapter 1 will begin by reviewing the current body of literature related to normal and disordered mechanisms of airway protection dysfunction in PD, skill training as an efficacious approach to rehabilitate cough dysfunction, and motor learning considerations to maximize treatment outcomes. Chapter 2 will characterize motor performance and learning during a voluntary cough skill training paradigm, and evaluate the contributions of physiologic (i.e., lung volume) and treatment-specific (i.e., biofeedback) factors to treatment response in PD. Chapter 3 will then characterize trajectories of motor performance during multiple sessions of sensorimotor cough skill training and explore the role of task-specific predictors (i.e., variability, motor learning) on motor performance. Chapter 4 will examine the effects of cough skill training with variable practice on motor performance and motor learning and characterize contributions of laryngeal and respiratory subsystems to cough strength. This document will then conclude (Chapter 5) by synthesizing results from these studies and discussing clinical implications, limitations, and potential directions for future research.

Utilization of airway protective rehabilitation among individuals with neurodegenerative disease is astoundingly low. Yet, due to progressive decline in airway protective function and resulting health consequences such as aspiration pneumonia, the need for rehabilitation is clear. Moreover, a growing literature supports the benefit of airway protective rehabilitation in neurodegenerative populations. Therefore, it is a healthcare priority to increase treatment utilization in order to improve health and quality of life for individuals with neurodegenerative disease. Improving treatment accessibility and relevance are two approaches that have the potential to improve utilization. Despite the need to increase treatment accessibility and the growing evidence base to support the use of telehealth to increase access, a significant gap remains in our understanding of the feasibility and acceptability of telehealth to manage dysphagia in neurodegenerative disease. Moreover, little is known about patient perspectives which are critical to refine person-centered models of care that are relevant to patient’s needs. To address this important clinical research gap, this dissertation includes a series of three research studies aimed at improving accessible and relevant rehabilitation for airway protective dysfunction in neurodegenerative disease. Chapter 1 will provide an overview of the current literature as it relates to airway protective dysfunction in neurodegenerative disease, existing rehabilitation approaches, telehealth to manage dysphagia, and the need for personalized care. Chapter 2 will examine the feasibility of rehabilitating airway protection via telehealth in individuals with neurodegenerative movement disorders. Chapter 3 will then explore speech language pathologists’ (SLPs) perspectives and experiences using telehealth to manage dysphagia. Chapter 4 will characterize patient perspectives on airway protective dysfunction and treatment experience following cough skill training (CST). I will conclude (Chapter 5) by synthesizing the findings from chapters 2-4 and suggesting directions for future research.

Introdução: A miastenia gravis (MG) é uma doença autoimune caracterizada por diminuição da força nos músculos voluntários, que se agrava com o esforço, podendo evoluir com alterações de voz e deglutição. Objetivo: Caracterizar as manifestações laríngeas da MG. Métodos: Foi realizado um estudo transversal por meio da avaliação de 37 pacientes portadores de MG, no período de maio de 2015 a novembro de 2016. Os pacientes foram recrutados no Ambulatório de Neurologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo/SP. Além dos dados clínicos e demográficos, todos os pacientes foram analizados pelo Índice de Desvantagem Vocal-10 (IDV-10), análise perceptivo-auditiva da voz, videolaringoestroboscopia e videoendoscopia da deglutição. Resultados: Na avaliação de voz, foi identificada disfonia em 89,2% dos sujeitos, sendo 59,5% de grau discreto e 29,7% moderado a grave. A autopercepção da desvantagem vocal foi significativamente maior nos pacientes diagnosticados com algum grau de disfonia. Foram identificadas alterações anatômicas em 8 pacientes à videolaringoestroboscospia. Ao comparar o grau da doença com as variáveis contração faríngea e sensibilidade laríngea na VED, observou-se maior ocorrência nos sujeitos com doença mais avançada e comprometimento bulbar. A associação entre as alterações de sensibilidade laríngea e estase indicou que os pacientes com ausência de sensibilidade tiveram estase para saliva, líquido e principalmente para purê e sólido. Conclusões: Portadores de MG apresentam alterações de voz e deglutição relacionadas à doença. A disfonia causa um impacto na vida do paciente com diagnóstico de MG. As alterções da deglutição estiveram presentes em pacientes com acometimento generalizado e maior evolução da doença / Introduction: Myasthenia gravis (MG) is an autoimmune disease characterized by a reduction in the strength of the voluntary muscles, aggravated by effort, with the possibility of developing with voice and deglutition disorders. Objective: Characterize the laryngeal manifestations of MG. Methods: A tranversal study was carried out by evaluating 37 patients with MG in the period between May 2015 and November 2016. Patients were recruited in the Neurology outpatient center at the Hospital das Clínicas, \"Faculdade de Medicina, Universidade de São Paulo\". Besides clinical and demographic data, all patients were analyzed according to the Vocal Disadvantage Index-10 (VDI-10), auditory-perceptual voice analysis, videolaryngostroboscopy and videoendoscopy of swallowing. Results: In the voice evaluation, dysphonia was identified in 89.2% of patients, 59.5% with a discreet degree and 29.7% from moderate to severe. Self-perception of the vocal disadvantage was significantly greater in patients diagnosed with some degree of dysphonia. Anatomical changes were identified in 8 patients through viodeolaryngostroboscospy. When comparing the degree of the disease with the variables pharyngeal contraction and laryngeal sensitivity in the VED, a greater incidence in patients with a more advanced disease and bulbar involvement was noticed. The association between the changes in laryngeal sensitivity and stasis showed that patients with a lack of sensitivity had stasis for saliva, liquid and mainly for purée and solids. Conclusions: MG patients present changes in voice and deglutition related to the disease. Dysphonia causes a great impact in the life of the patient diagnosed with MG. Changes in deglutition were present in patients with generalized involvement and greater progression of the disease

Estudos têm tentado compreender a relação entre a SAOS e disfagia orofaríngea, porém ainda existem dúvidas sobre o tema. O objetivo deste estudo foi verificar se aspectos miofuncionais orofaciais, respiratórios e de coordenação neuromuscular oral e laríngea se relacionam com sinais e sintomas de disfagia orofaríngea em indivíduos com SAOS. Para isso foram avaliados 12 adultos com mediana de 43 anos e diagnóstico de SAOS comprovado por meio de exame de polissonografia. Todos os participantes foram submetidos a cálculo do índice de massa corporal (IMC), medida da circunferência do pescoço, avaliação do espaço orofaríngeo por meio do grau de Mallampati, aplicação do questionário de sintomas de disfagia orofaríngea EAT 10, avaliação da deglutição durante a videofluoroscopia com aplicação da Dysphagia Outcome and Severity Scale DOSS e Escala de Resíduos, exame miofuncional orofacial utilizando o Protocolo MBGR, avaliação da pressão de língua utilizando o Iowa Oral Performance Instrument (IOPI), provas de diadococinesia (DDC) oral e laríngea, avaliação da capacidade inspiratória com o uso do Peak Nasal Inspiratory Flow (PNIF). Os dados foram tabulados, analisados estatisticamente por meio do teste de Correlação de Ponto Bisserial e Correlação de Spearman, considerando o nível de significância de 5% (p<0,05). Os pacientes apresentaram IMC e circunferência cervical acima da normalidade, grau IV de Mallampati, pontuação do EAT 10 entre 0 e 3 pontos e Nível 6 na DOSS em sua maioria; escala de Resíduos com graus 1 e 2 com presença de resíduos em língua, valécula e esfíncter esofágico superior para líquido e pudim; tonicidade e mobilidade orofacial alteradas; modo respiratório nasal; tipo respiratório superior; desempenho nas provas elevação, lateralização e protrusão do IOPI abaixo da normalidade; parâmetros de média e perturbações do período abaixo da normalidade na DDC oral e laríngea e valores do PNIF abaixo da normalidade. Ao correlacionar os dados da VDF com as demais avaliações houve correlação forte a moderada e significante (p<0,05) entre as provas de lateralização de língua à direita e protrusão do IOPI com resíduos na língua e intraesofágico; valores do PNIF com atraso do início da fase faríngea, resíduos em seios piriformes e faringe; valores da DDC oral e laríngea com resíduos em valécula e na língua, escape posterior prematuro, atraso do início da fase faríngea e alteração da função de língua. Portanto, conclui-se que os aspectos de pressão de língua, pico do fluxo inspiratório nasal e coordenação neuromuscular oral e laríngea apresentaram relação com sinais de Disfagia Orofaríngea nos indivíduos com SAOS desta amostra. / Studies have tried to find a relationship between obstructive sleep apnea syndrome and oropharyngeal dysphagia, but many questions still remain. The aim of this study was to verify if orofacial myofunctional aspects, respiratory aspects and oral and laryngeal neuromuscular coordination are related to signs and symptoms of oropharyngeal dysphagia in individuals with OSAS. For it, 12 adults with a median of 43 years were evaluated, who has a diagnosis of OSAS verified by polysomnography. All patients were undergo calculation of body mass index (BMI), measured the neck circumference, evaluation of oropharyngeal space through the Mallampati grade, application of the questionnaire of symptoms of oropharyngeal dysphagia EAT 10, swallowing evaluation during videofluoroscopy with the application of Dysphagia Outcome and Severity Scale - DOSS and Scale of Residues, orofacial myofunctional examination using MBGR Protocol, evaluation of tongue pressure using the Iowa Oral Performance Instrument (IOPI), oral and laryngeal diadochokinesia tests, inspiratory flow using the Peak Nasal Inspiratory Flow (PNIF). The data were tabulated, statistically analyzed using the Bisserial Point Correlation and Spearman Correlation test, considering the significance level of 5% (p<0.05). Patients had BMI and cervical circumference above normal, Mallampati grade IV, EAT 10 score between 0 and 3 points and Level 6 in DOSS mostly, Scale of Residues with grades 1 and 2 with presence of residuals in tongue, vallecula and upper esophageal sphincter for liquid and pudding, altered orofacial tonicity and mobility, nasal respiratory mode, upper respiratory type, performance in the IOPI elevation, lateralization and protrusion tests below normality, parameters of mean of period and period dysfunction below normality in oral and laryngeal DDC and PNIF values below normality. When correlating VDF data with the other evaluations, there was a strong to moderate and significant correlation (p<0.05) between the tests of right tongue lateralization and protrusion of IOPI with residuals in the tongue and intraesophageal; PNIF values with delayed onset of pharyngeal phase, residuals in pharyngeal and pyriform sinuses; values of oral and laryngeal DDC with residuals in vallecula and tongue, premature posterior leakage, delayed pharyngeal phase onset and altered tongue function. Therefore, it was concluded that the aspects of tongue pressure, peak nasal inspiratory flow and oral and laryngeal neuromuscular coordination were related to signs of Oropharyngeal Dysphagia in individuals with OSAS.

Introdução: A esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa progressiva, de etiologia desconhecida, que envolve os neurônios motores do córtex cerebral, do tronco encefálico e da medula espinhal. O comprometimento dos neurônios motores inferiores causa disfagia, distúrbios de fala e outros sintomas, como fraqueza muscular global e sintomas respiratórios. A dificuldade de deglutição ou disfagia pode causar complicações, como pneumonia aspirativa, má nutrição e desidratação, e afeta a qualidade de vida destes pacientes, sendo necessária a indicação de via alternativa de nutrição. Atualmente, esta indicação é dada subjetivamente pelo exame clínico e funcional realizado pela equipe multidisciplinar, de acordo com a deterioração dos parâmetros da função respiratória, do estado nutricional e de comprometimentos na deglutição. Objetivos: objetivo geral: verificar se a redução de pressão de língua pode ser indicadora de necessidade de gastrostomia (GEP) como via alternativa de nutrição em pacientes com diagnóstico de ELA. Objetivos específicos: verificar se há redução significativa nas medidas funcionais e de pressão de lábio, de língua e de bochecha entre o momento da primeira avaliação e da indicação da GEP; avaliar o tempo desde o primeiro sintoma da doença até a indicação da GEP; verificar se o tempo de indicação da GEP foi influenciado por variáveis demográficas, manifestação clínica inicial (espinhal ou bulbar), condições clínicas, medidas funcionais globais e de deglutição, com destaque para pressão de língua, de lábios e de bochechas. Métodos: Foram estudados longitudinalmente 63 pacientes, avaliados do ponto de vista fonoaudiológico com os instrumentos: escala ASHA, escala ALSFRS, avaliação funcional, medida de pressão dos órgãos fonoarticulatórios com o aparelho IOPI, encaminhamento para videoendoscopia da deglutição (VED) e capacidade vital forçada (CVF) no momento da indicação da GEP. Resultados: Os pacientes tinham faixa etária entre 28 e 79 anos (média de 58 anos de idade), com média de 7,04 anos de escolaridade, tempo médio de doença no momento da avaliação inicial de 34,96 meses, 32% manifestação clínica inicial da forma bulbar, 39,5% espinhal membros superiores e 28,5% espinhal membros inferiores, porém, na avaliação fonoaudiológica inicial, todos apresentavam alguma queixa de acometimento bulbar. Cinquenta pacientes foram encaminhados à GEP, 1 foi a óbito e 12 mantiveram dieta via oral exclusiva até o término do estudo. Medidas funcionais e de pressão de língua, lábio e bochecha apresentaram redução significativa no agravamento da ELA (p < 0,001). Dificuldades com líquido espessado: de contenção (p=0,001), de transporte (p=0,005) e de proteção de vias aéreas inferiores (p =0,003), e com a consistência pastosa: contenção na cavidade oral, (p < 0,001) observadas em avaliações clínicas fonoaudiológicas, e a idade (p =0,014) influenciam na indicação de GEP. Conclusão: A medida de pressão de língua pode, portanto, servir como um indicador adicional, objetivo e prático para o exame do prognóstico da funcionalidade da deglutição, e, em particular, da possibilidade ou não de manutenção de vias tradicionais em pacientes com diagnóstico de ELA / Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease of unknown etiology that involves motor neurons from the cerebral cortex, from the brainstem and from the spinal cord. The damage on the lower motor neurons causes dysphagia, speech disorders and other symptoms such as overall muscle weakness and respiratory symptoms. The difficulty in swallowing, or dysphasia, may cause complications such as aspiration pneumonia, malnutrition and dehydration and affects the quality of live of these patients. Thus, it is necessary to indicate and alternative form of nutrition. This indication is currently given subjectively by the clinical and functional evaluation performed by the multidisciplinary team, according to deterioration of respiratory function parameters, nutritional status and swallowing impairments. Objectives: general objective: verify if reduced tongue pressure could indicate the need for gastrostomy (PEG) as an alternative form of nutrition for patients who have been diagnosed with ALS. Specific objectives: verify if there is significant reduction on tongue, lips, and cheeks pressure as well as functional measures between the moment of the first evaluation and the indication of PEG; evaluate the time between the first symptom of the disease and the indication of PEG; verify if the time of the indication of PEG was influenced by demographic variables, initial clinical manifestation (spinal or bulbar forms), clinical conditions, global and swallowing functional measures, highlighting tongue, lips and cheeks pressure. Methods: 63 patients have been longitudinally studied. They have been assessed from the speech-language therapy point of view with the following instruments: ASHA, ALSFRS, functional evaluation, pressure measurement of the phono-articulatory organs with the IOPI, referral to videoendoscopy of swallowing and FVC at the moment of the indication of PEG. Results: The patients, whose ages ranged from 28 to 79 years old (average of 58 years old), had, on average, 7.04 years of education. They had been suffering from the disease for an average of 34.96 months at the time of the first evaluation. 32% showed initial clinical manifestation of the bulbar form, 39.5% upper limbs spinal form and 28.5% lower limbs spinal form. At the initial speech-language therapy assessment, however, all of them showed some sort of complaint regarding bulbar impairment. 50 patients were sent to PEG, 1 died and 12 continued with an oral exclusive diet until the end of this study. Tongue, lips and cheeks as well as functional measures showed significant decrease with the aggravation of ALS (p < 0,001). Difficulties with thickened liquid: with containment (p=0,001), with transport (p=0,005) and with protection of lower airways (p =0,003) and with pasty consistencies: containment in the oral cavity, (p < 0,001) observed in speech-language therapy clinical assessments, as well as age (p =0,014) have influence on the indication of PEG. Conclusion: The measure of the tongue pressure can, therefore, serve as an additional, objective and practical indicator for the evaluation of the prognosis of swallowing functionality, particularly of the possibility or not of maintenance of traditional forms in patients who have been diagnosed with ALS

O corpo humano executa uma determinada função ao se alimentar, a qual promove a condução do alimento ao estômago. Esta função é denominada deglutição. A deglutição pode ser afetada, pela falta de secreção salivar, por processos mecânicos que dificultam a passagem do bolo, ou pela fraqueza das estruturas musculares responsáveis pela disfunção da rede neuronal que coordena e controla a deglutição, e também pela propulsão do bolo alimentar. A dificuldade na deglutição ou disfagia, geralmente reflete problemas que envolvem a transição esofagogástrica, a cavidade oral, faringe e esôfago. Esta disfagia pode trazer alguns problemas ao indivíduo, como entrada de alimento na via aérea, na qual provocam problemas pulmonares, tosse, sufocação/ asfixia ou aspiração. Além disso, traz danos relacionados ao estado nutricional do indivíduo, como perda de peso, desidratação e até mesmo morte. A disfagia orofaríngea neurogênica pode ser causada por doenças neuromusculares degenerativas, encefalopatias, demências, traumas de cabeça ou pescoço, ou acidente vascular cerebral (AVC). A avaliação clínica da deglutição, tem como objetivo identificar alterações da fisiologia da dinâmica da deglutição, fornecer a necessidade ou não de exames objetivos, identificar as fases comprometidas, o grau de severidade, a classificação da disfagia, enfim, colher informações que possam auxiliar num diagnóstico e conduta terapêutica mais adequada. Este estudo teve como objetivo descrever a eficácia e importância da avaliação clínica da deglutição, tendo como referência a avaliação objetiva da deglutição (nasolaringofibroscopia), em pacientes com disfagia orofaríngea neurogênica, com diagnóstico de Acidente Vascular Cerebral (Isquêmico ou Hemorrágico), Doença de Alzheimer e Doença de Parkinson. Foram avaliados 35 pacientes, 6 do gênero feminino e 29 do gênero masculino, que apresentaram a faixa etária de 52-82 anos. A avaliações foram realizadas no mesmo dia, sendo feita primeiramente a avaliação clínica seguindo protocolo proposto por Silva (2004) e posteriormente a avaliação nasofibroscópica da deglutição, seguindo protocolo proposto por Langmore et al (1988); Aviv et al (1998); Macedo Filho (2003). Ocorreram coincidências entre os achados dos resultados da avaliação clínica da deglutição, tendo como padrão a avaliação nasofibroscópica. Houve uma forte correspondência e associação entre as escalas da avaliação clínica e nasofibroscópica. Com base nos achados adquiridos neste estudo, conclui-se que a avaliação clínica da deglutição deve ser realizada no paciente com disfagia orofaríngea neurogênica, pois o fonoaudiólogo pode determinar um diagnóstico adequado, classificar a disfagia quanto ao tipo e grau de severidade; detectar os problemas durante a deglutição; auxiliar na conduta terapêutica; determinar qual via de alimentação e determinar quais manobras específicas da deglutição podem ser utilizadas no paciente avaliado. / The human body performs a certain function by feeding, which promotes driving of the food to the stomach. This is called swallowing. Swallowing can be affected by the lack of saliva secretion, by mechanical means which hinder the passage of the bolus, or muscle weakness of the structures responsible for the dysfunction of the neuronal network that coordinates and controls swallowing, and also by propulsion of the bolus. The difficulty in swallowing or dysphagia, generally reflects problems involving the esophagogastric junction, oral cavity, pharynx and esophagus. This dysphagia may bring some trouble to the individual, such as food intake in the air, which cause lung problems, coughing, choking / suffocation or aspiration. Furthermore, brings harm related to the nutritional status of the individual, such as weight loss, dehydration and even death. The neurogenic oropharyngeal dysphagia can be caused by degenerative neuromuscular diseases, encephalopathy, dementia, head trauma or neck, or stroke. Clinical evaluation of swallowing, aims to identify physiological changes of the swallowing dynamics, provide the necessity of objective tests, identify compromised phases, the degree of severity, dysphagia classification, finally, gather information that can help a diagnosis and improve treatment. This study aimed to describe the effectiveness and importance of clinical evaluation of swallowing, with reference to the objective evaluation of swallowing (nasolaringofibroscopia) in patients with neurogenic oropharyngeal dysphagia, with a diagnosis of stroke (ischemic or hemorrhagic), Alzheimer\'s Disease and Parkinson\'s disease. We evaluated 35 patients, 6 females and 29 males, who presented the age group of 52-82 years. The evaluations were performed on the same day, being first made the following clinical evaluation protocol proposed by Silva (2004) and later the nasofibroscopy swallowing, following the protocol proposed by Langmore et al (1988); Aviv et al (1998); Macedo Filho (2003). There were similarities between the findings of the results of the clinical evaluation of swallowing, and defaults to nasofibroscopy. There was a strong correlation and association between the scales of clinical and nasofibroscopy. Based on the findings obtained in this study, it is concluded that the clinical evaluation of swallowing should be performed in patients with neurogenic oropharyngeal dysphagia because the audiologist can determine a proper diagnosis, sort dysphagia on the type and severity; detect problems during swallowing; support therapeutic conduct; determine which power via determine which specific maneuvers of swallowing can be used in the patient assessed.
