Effect of Visual Biofeedback Obtained Using the Iowa Oral Performance Instrument on the Suprahyoid Muscle Activation Level During Effortful Swallowing Maneuver
AbstractEffortful swallowing (ES) is a maneuver prescribed for patients who experience pharyngeal residues after swallowing owing to weakness of the tongue and pharyngeal constrictor muscles. ES can increase the pharyngeal contraction force by intentionally increasing the degree of effort during swallowing. However, the effect is limited as the nature of swallowing makes it difficult to maintain a constant high-effort level. The aim of this study was to assess the effect of visual feedback, delivered by the Iowa Oral Performance Instrument (IOPI), a tongue pressure measurement device on ES maneuver effort. Overall, 34 heal...

Chicago Classification Version 4.0 Improves Stratification of Ineffective Esophageal Motility Patients into Clinically Meaningful Subtypes: A Two-Center International Study
AbstractThe 4th iteration of the Chicago Classification (CC v4.0) for esophageal motility disorders offers more restrictive criteria for the diagnosis of Ineffective Esophageal Motility (IEM) compared to version 3.0 (CC v3.0). In light of the updated criteria for IEM, we aimed to characterize and compare the patients who retained their IEM diagnosis to those who were reclassified as normal motility, and to evaluate the clinical impact of the newly introduced CC v4.0. We performed a retrospective case –control study. We included all individuals who underwent a high-resolution manometry (HRM) between 2020 and 2021 at two c...

Pharyngeal Structure and Dysphagia in Patients with Parkinson ’s Disease and Related Disorders
AbstractPharyngeal muscle changes occur in patients with Parkinson ’s disease and related disorders (PRD); however, the association between the structural alterations in the pharynx and the symptoms of dysphagia remains unclear. We assessed structural changes and contractile forces by measuring pharyngeal wall thickness and width. We aimed to define the pharyngea l measurements and determine their value as diagnostic tools for dysphagia. The pharyngeal wall thickness (PWT), pharyngeal width at rest (PWR), and shortest pharyngeal width at swallowing (PWS) were measured using lateral neck roentgenograms and videofluorosco...

Timing of True Vocal Cords Closure for Safe Swallowing: A Review of 5 Studies Using 3D Analysis Using Computerized Tomography (CT)
AbstractTimely and complete laryngeal closure is critical for a successful swallow. Researchers have studied laryngeal closure, including true vocal cords (TVC) closure, closure of the arytenoids to the epiglottis base (laryngeal vestibule closure), and epiglottic inversion, but the most commonly available imaging tools have limitations that do not allow the study of these components individually. Swallowing computerized tomography (CT) has enabled three-dimensional dynamic visualization and quantitative evaluation of swallowing events providing a unique view of swallowing-related structures and their motion. Using CT, TVC...

Difference in the Electromyographic Behavior of the Masticatory and Swallowing Muscles During Cued Versus Spontaneous Swallowing
AbstractThe risk of dysphagia and/or aspiration is determined using screening tests, such as the repeated saliva swallowing test and modified water swallowing test, which evaluate cued swallowing. However, humans masticate and swallow foods with various consistencies, forms, and amounts, without conscious awareness. Therefore, this study aimed to examine the difference in the behavior of masticatory and swallowing muscles during spontaneous versus cued swallowing through a series of mastication and swallowing processes by evaluating surface electromyogram (sEMG) signals. The effect of the consistency and amount of food on ...
