Despite the high estimated prevalence of dysphagia in OSA, there is a paucity of evidence supporting behavioral interventions for treatment. The purpose of this study was to assess the impact of expiratory muscle strength training (EMST) on validated, standardized metrics of swallow and airway clearance capacity functions in moderate-to-severe OSA. 10 participants with OSA (mean age = 65.

This study investigated sequential swallowing biomechanics in healthy adults. Archival normative videofluoroscopic swallow studies were analyzed for hyolaryngeal complex (HLC) patterning and biomechanical measures from the first 2 swallows of a 90-mL thin liquid sequential swallow task.

Purpose: Spinal pathology is very common with advancing age and can cause dysphagia; however, it is unclear how frequently these pathologies affect swallowing function. This study evaluates how cervical spinal pathology may impact swallowing function in dysphagic individuals observed during videofluoroscopic swallowing studies (VFSSs).
Method: A retrospective case-control study was performed on 100 individuals with dysphagia as well as age-/gender-matched healthy controls (HCs) with available VFSS.
The purpose of this systematic review was to examine the application of event-related potentials (ERPs) to investigate neural processes of swallowing functions in adults with and without dysphagia. Computerized literature searches were performed from three search engines. Studies were screened using Covidence (Cochrane tool) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards (PRISMA-2009).

Thirty-six patient-caregiver pairs completed the Swallowing Quality of Life Questionnaire (SWAL-QOL) using an online survey format. Additional background and clinical information was ascertained.

Purpose: The aim of this study was to identify factors influencing pharyngeal laterality of bolus clearance through the pharyngoesophageal segment.
Method: Two swallowing trials (5-ml nectar-thickened liquid and 5-ml pudding) administered in the anteroposterior viewing plane during videofluoroscopy were extracted from a normative database of 195 healthy adult participants. Each swallow was determined as either having no laterality, right dominance/right side only, or left dominance/left side only.

Background: Post-operative dysphagia is one of the most common complications of anterior cervical spine surgery (ACSS).
Objective: Examine post-operative structural and physiologic swallowing changes in patients with dysphagia following ACSS as compared with healthy age and gender matched controls.
Methods: Videofluoroscopic swallow studies of adults with dysphagia after ACSS were retrospectively reviewed.
At the time of writing this paper, there are over 11 million reported cases of COVID-19 worldwide. Health professionals involved in dysphagia care are impacted by the COVID-19 pandemic in their day-to-day practices. Otolaryngologists, gastroenterologists, rehabilitation specialists, and speech-language pathologists are subject to virus exposure due to their proximity to the aerodigestive tract and reliance on aerosol-generating procedures in swallow assessments and interventions.

Although anticholinergic medications are first-line therapy, they often lead to unacceptable side effects. Radiation therapy and botulinum toxin may be considered when medical management fails.

Further, risk of mortality increases with concomitant presence of cachexia in the COPD population. The purpose of this prospective study was to depict oropharyngeal swallowing physiology in underweight patients with stable but advanced-stage COPD.
View Article and Find Full Text PDFObjective: Laryngeal endoscopy with stroboscopy, a critical component of the assessment of voice disorders, is rarely used as a treatment outcome measure in the scientific literature. We hypothesized that this is because of the lack of a widely used standardized, validated, and reliable method to assess and report laryngeal anatomy and physiology, and undertook a systematic literature review to determine the extent of the inconsistencies of the parameters and scales used in voice treatment outcome studies.
Study Design: Systematic literature review.
Videofluoroscopic imaging of swallowing known as the Modified Barium Study (MBS) is the standard of care for assessing swallowing difficulty. While the clinical purpose of this radiographic imaging is to primarily assess aspiration risk, valuable biomechanical data is embedded in these studies. Computational analysis of swallowing mechanics (CASM) is an established research methodology for assessing multiple interactions of swallowing mechanics based on coordinates mapping muscle function including hyolaryngeal movement, pharyngeal shortening, tongue base retraction, and extension of the head and neck, however coordinates characterizing pharyngeal constriction is undeveloped.
