“…Searching the literature revealed that the precedent terminology for swallowing speed is heterogeneous and includes particularly the terms “swallowing velocity,” “swallowing capacity,” “flux of ingestion,” or “swallowing flow” as well . Considering all these terms, we found five studies assessing swallowing speed primarily in PD patients but none with an objective evaluation of aspiration using either FEES or VFSS .…”

Background There is still a lack of a clinical test to reliably identify patients with Parkinson's disease (PD) being at risk for aspiration. Methods In this prospective, controlled, cross‐sectional study, we assessed if swallowing speed for water is a useful clinical test to predict aspiration proven by flexible endoscopic evaluation of swallowing (FEES). Due to this, we measured the swallowing speed for 90 mL water in 115 consecutive and unselected PD outpatients of all clinical stages and 32 healthy controls. Key Results Average swallowing speed was lower in patients compared with controls (6.5 ± 3.9 mL/s vs 8.5 ± 3.2 mL/s; P < .01). The disease‐independent widely used threshold of <10 mL/s showed insufficient sensitivity of 88% and specificity of 19% with high false‐positive rates of 63% for patients and 69% for controls. Receiver operating characteristic (ROC) analysis was carried out to define a suitable cutoff value for detection of aspiration of water (area under the curve 0.72, P < .001) in PD patients. The optimized cutoff value was 5.5 mL/s with a sensitivity of 69% and a specificity of 64%. Conclusion and Inferences Measuring swallowing speed is prone to methodological errors and not suitable as a screening instrument to predict aspiration in PD patients.

Swallowing is a process in which the food bolus is taken into the mouth and broken down to be transported from the oral cavity to the stomach via the pharynx and oesophagus. In this process, over 30 nerves and muscles in the face, mouth, pharynx, larynx and oesophagus work in precise temporal and spatial coordination. 1 In particular, during pharyngeal swallowing, in which the bolus passes through the pharynx and is transported into the oesophagus, organs and muscles attached to the pharynx and larynx act in concert to close the airway and transport the bolus in less than a second, without the risk of aspiration or choking. 2 Thus, it is important to evaluate the movement of the larynx Abstract Background: Movement of the hyoid and laryngeal complex is critical for preventing aspiration, as well as smooth bolus passage through the pharynx. We have developed a non-invasive system for measuring laryngeal movement during swallowing with a bend sensor and have already reported the time coordination between the signal waveform from the sensor and hyoid movement.Objective: The aim of this study was to clarify the quantitative association between the output value of the sensor and hyoid movement during swallowing.Methods: A small bend sensor was fixed on the skin surface along the midline of the neck of 13 healthy men (mean age, 30.8 ± 4.5 years). Laryngeal and hyoid movements during swallowing of 5 mL of water were recorded synchronously by the bend sensor and videofluorography. The relationship between the bend sensor output value (LM value) and hyoid position (x-and y-axis displacements) by videofluorography from the onset to the offset of the signal waveform was analysed for all tasks and for each task using Pearson's correlation coefficients.Results: There was a positive correlation between the LM value and hyoid position for all tasks (x-axis displacement: r = .647, y-axis displacement: r = .233). In particular, there was a moderate to high correlation between the LM value and x-axis displacement for each task (.453 ≤ r ≤ .934). Conclusion:The LM value can be a quantitative parameter of anterior hyoid movement during swallowing that might be associated with bolus flow and upper oesophageal sphincter opening.

“…The literature describes the existence of anatomical and functional differences between men and women throughout the digestive tract (oral cavity, pharynx, upper esophageal sphincter, and esophagus) 1,6 . According to the literature, women demonstrate higher oropharyngeal transit times 5,6 , longer durations of the upper oesophageal sphincter opening 26 , shorter time periods between swallows and lower food bolus volume for each swallowing 13 , longer durations of laryngeal closure during swallowing 1 , and early laryngeal closure relative to the upper esophageal sphincter opening 11 compared with men. Hiss et al 9 also reported that women present longer swallowing apnea.…”

-Background: Videofluoroscopy is considered the "gold standard"procedure for the evaluation of swallowing by most units that treat patients with dysphagia, having a great impact in decision making, not only in therapeutic terms, but also in determining the prognosis. Aim: To propose and to verify the reproducibility of the results of a perceptual two-dimensional videofluoroscopic protocol for the analysis of the pharyngeal phase of swallowing in a population of healthy adults. Methods: Participants were 20 healthy adults, of both genders, with ages between 50 and 65 years. Videofluoroscopy was performed during the swallow of the following consistencies: 10 ml of liquid; 7 ml of paste; and half a "salt and water" biscuit. The protocol was composed by four parts: assessment of the pharyngeal transit time; assessment of the duration of the tongue base movement to the posterior pharyngeal wall; valleculae residue ratio; assessment of penetration/aspiration. Statistical analysis involved the assessment of data reproducibility between raters and analysis of the quantitative data regarding gender. Results:Comparison among raters indicated that data was highly reproducible. No significant differences were found between genders for pharyngeal transit time; for the duration of the tongue base movement to the posterior pharyngeal wall; and for the valleculae residue ratio. Conclusion: The perceptual two-dimensional videofluoroscopy analysis demonstrated to be a reproducible method. Valleculae residue was present in 40% of the study sample, suggesting that this parameter alone does not indicate alterations of the pharyngeal phase of swallowing. RESUMO -Racional:A videofluoroscopia é considerada o procedimento "padrão-ouro" para avaliação da deglutição pela maioria das unidades que atendem pacientes com disfagia, tendo grande impacto na tomada de decisão, não só em termos terapêuticos, como também na determinação do prognóstico. Objetivo: Propor e verificar a reprodutibilidade de protocolo de análise videofluoroscopica bidimensional perceptual da fase faríngea da deglutição em uma população de adultos saudáveis. Métodos: Participaram desta pesquisa 20 indivíduos saudáveis, de ambos os gêneros, com idades entre 50 e 65 anos. O exame foi realizado durante a ingestão de "alimentos" com as seguintes consistências: 10 ml de líquido; 7 ml de pastoso; e meio biscoito do tipo "água e sal". O protocolo proposto foi composto de quatro partes: avaliação do tempo de trânsito faríngeo; avaliação da duração do contato da base de língua na parede posterior da faringe; avaliação da porcentagem de resíduo alimentar em valécula; avaliação de penetração e aspiração na árvore respiratória. A análise estatística envolveu a avaliação da reprodutibilidade do método de análise entre avaliadores e a análise dos dados quantitativos, levando-se em consideração os gêneros. Resultados: Pela análise comparativa entre os avaliadores houve alta reprodutibilidade. Não foram encontradas diferenças estatisticamente significantes para o tempo de trâns...
