“…There is also evidence of negative outcomes associated with increased thickness: the IDDSI review [26**] identified greater vallecular residue for thicker consistencies [39,41,50,51] and Troche et al [40] observed a greater number of tongue pumps required to swallow a pudding-thick consistency than a thin liquid. This trend was also recently observed for starch-but not gum-based thickeners [37*] (with equal apparent viscosity) with significantly more oral and pharyngeal residue was apparent for starch vs gum at thicker consistencies.…”

Purpose: Texture modification is a widespread practice as a strategy for the management of dysphagia and can be very effective in individual cases. However, it is often performed in a qualitative, subjective manner and practices vary internationally according to multiple sets of national guidelines. This paper aims to identify best practice by reviewing the theory and practice of texture modification, focussing on recent advances. Recent findings:Instrumental assessment of texture modification in-vivo is challenging, but studies including rheology and perception have indicated that fluid viscosity is only one of many factors affecting texture modification in practice. Systematic reviews have identified a historical lack of high-quality clinical evidence, but recent controlled studies are beginning to identify positive and negative aspects of thickened fluids. Research and practice to date have been limited by the lack of control and standardisation of foods and drinks. However in 2015 a notfor-profit organisation, the International Dysphagia Diet Standardisation Initiative, has published a framework for texture modification from thin liquids to solid foods based on all the existing documentation and guidance, and the -limited-available clinical evidence. Summary:Rheology exists in the lab, however normal practice is often subjective or lacking control and standardisation. In the near future, cohesion of practice and the availability of practical standardisation tools may increase awareness and use of rheology. KeywordsDysphagia, Swallowing, Rheology, Viscosity, Texture modification Key points •The relationships between rheology and swallowing are beginning to be characterised using oral pressure sensing and videofluoroscopy, together with careful control of bolus rheology.• It is becoming clearer that viscosity alone is not sufficient to categorise texture modification.• Literature to date shows a trend for reduced aspiration with increased thickness of liquids, and increased residue with some thicker consistencies, however evidence is scarce.• An inconsistent approach to definition of texture modification techniques has been limiting the collation of a coherent evidence base.• A new international standard (IDDSI) has been created, drawing on available evidence and including practical objective measures.

“…Parece claro, após esta revisão, que há diferenças tanto na aplicabilidade quanto na eficácia deste método quando usado para populações com disfagia mecânica e neurogênica, sendo ainda necessário esclarecer dentre estas, qual a etiologia das mais beneficiadas (34,36) . Assim, confirmando a tendência dos estudos de eficácia em disfagia e independente dos métodos terapêuticos aplicados, há de se considerar a especificidade das etiologias, caso queiramos comprovar a atuação de práticas fonoaudiológicas.…”

INTRODUÇÃOA disfagia é uma condição que submete o indivíduo a constante instabilidade clínica, podendo ocasionar complicações como pneumonia aspirativa, desidratação, desnutrição e óbito. Devido a estas questões, este sintoma pode aumentar os custos dos cuidados de saúde com o indivíduo disfágico, bem como prolongar a duração da estada hospitalar (1) . Desta forma, distintas tem sido as propostas para a reabilitação da disfagia orofaríngea pesquisadas ao longo dos anos e discutidas por alguns artigos de revisão (2)(3)(4) . A mais nova abordagem proposta para a reabilitação da disfagia orofaríngea trata-se da eletroestimulação neuromuscular (EENM), considerada uma técnica não invasiva, aplicada através de eletrodos de forma transcutânea. Considerada um dos recursos terapêuticos atuais para a disfagia orofaríngea, a EENM é usada desde 1997 nos Estados Unidos, quando aprovada pelo Food and Drug Administration (FDA), com a finalidade de promover movimentação suprahióidea, laríngea e para o favorecimento da contração dos grupos musculares envolvidos diretamente com a deglutição (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) . A EENM vem sendo citada como tendo um importante papel em vários segmentos na clínica da reabilitação. A EENM pode ser usada para conseguir o aumento efetivo na força muscular, no tratamento das limitações da amplitude de movimento das articulações devido a restrições de tecidos moles ou fraqueza, para a redução da debilidade no desempenho neuromuscular minimizando a incapacidade associada a espasticidade, para a redução das debilidades de controle do movimento, nos músculos inativos e para favorecer a criação de um feedback que maximize o desempenho muscular após exercícios de contração muscular voluntária (17)(18)(19)(20)(21) . O objetivo do presente estudo foi apresentar revisão bibliográfica sobre a aplicabilidade e a eficácia da eletroestimulação neuromuscular na reabilitação da disfagia orofaríngea, a partir de um amplo levantamento bibliográfico nas bases de dados (SciELO, LILACS, PubMed e Cochrane), entre 1983 à 2010, e livros sobre a área. REVISÃO DE LITERATURAA EENM terapêutica foi proposta como uma opção de tratamento para a disfagia orofaríngea, demonstrando benefí-cios para disfágicos após Acidente Vascular Encefálico (AVE), pós-radioterapia, em pacientes com xerostomia (22) , tensões e dores, com resultados favoráveis para o aumento na qualidade vocal e na deglutição desta população (20) . No entanto, pouco

“…Many of the studies investigating the effect of NMES in the treatment of dysphagia compared swallowing ability and the occurrence of penetration and aspiration before and after therapy as indicators of the effectiveness of the therapeutic procedure [ [29,32,34,37,39,40,41,42,43,44,48,49,51,52,53,54,55,56,57,58,59,60] amongst others, see tables 1, 3 for an overview]. Some studies, especially the earlier ones, were criticized regarding their study designs [29,32,34].…”

Objective: Neuromuscular electrical stimulation (NMES) has been proposed in the treatment of laryngopharyngeal dysfunctions (dysphonia, dyspnoea, dysphagia) for more than 40 years. Several studies have investigated possible therapeutic effects. Some researchers described favourable results, whereas others did not find relevant benefits. This article aims to review available studies to give an overview regarding the current state of knowledge. Methods: We conducted a selective literature search using PubMed. Results: In total, 356 papers were identified: 6 case reports, 11 reviews, 43 prospective clinical trials and 3 retrospective trials were found. Conclusion: Due to different stimulation protocols, electrode positioning and various underlying pathological conditions, summarizing the present studies appears to be difficult. However, there is evidence that NMES is a valuable adjunct in patients with dysphagia and in patients with vocal fold paresis. Nevertheless, more empirical data is needed to fully understand the benefits provided by NMES. Further research suggestions are put forward.
