Advances with Neonatal Aerodigestive Science in the Pursuit of Safe Swallowing in Infants: Invited Review
AbstractFeeding, swallowing, and airway protection are three distinct entities. Feeding involves a process of sequential, neurosensory, and neuromotor interactions of reflexes and behaviors facilitating ingestion. Swallowing involves anterograde bolus movement during oral-, pharyngeal-, and esophageal phases of peristalsis into stomach. During these events, coordination with airway protection is vital for homeostasis in clearing any material away from airway vicinity. Neurological –airway-digestive inter-relationships are critical to the continuum of successful feeding patterns during infancy, either in health or dis...

25  Years of Dysphagia Rehabilitation: What Have We Done, What are We Doing, and Where are We Going?
AbstractAs deglutologists, we strive to use the best evidence available in the treatment of swallowing disorders. Evidence-based medicine is a bottom-up approach that thoughtfully combines the best external evidence with individual clinical expertise and the patients ’ choice reflective of their clinical state and preferences for their specific care plan. Evidence-based medicine is not restricted to randomized clinical trials and meta-analyses; rather, evidence-based medicine includes our ability to discriminate the best external evidence with which to answer clinical questions and then skillfully and appropriately b...

Progression of Dysphagia in Spinocerebellar Ataxia Type 6
AbstractSpinocerebellar ataxia type 6 (SCA6), an autosomal dominant triplet repeat disease, predominantly affects the cerebellum with a late onset and generally good prognosis. Dysphagia is commonly associated with the outcomes of neurodegenerative diseases such as SCA6. Although the characteristics of dysphagia have been rarely reported in SCA6, our previous study indicated that dysphagia is generally milder in SCA6 than in SCA3, another inherited ataxia with multisystem involvement. However, abnormalities in the pharyngeal phase in SCA6 were indistinguishable from those in SCA3, with no explainable reason. To determine t...

Evaluating the Psychometric Properties of the Eating Assessment Tool (EAT-10) Using Rasch Analysis
AbstractEarly and reliable screening for oropharyngeal dysphagia (OD) symptoms in at-risk populations is important and a crucial first stage in effective OD management. The Eating Assessment Tool (EAT-10) is a commonly utilized screening and outcome measure. To date, studies using classic test theory methodologies report good psychometric properties, but the EAT-10 has not been evaluated using item response theory (e.g., Rasch analysis). The aim of this multisite study was to evaluate the internal consistency and structural validity and conduct a preliminary investigation of the cross-cultural validity of the EAT-10; floor...

Pre-pharyngeal Swallow Effects of Recurrent Laryngeal Nerve Lesion on Bolus Shape and Airway Protection in an Infant Pig Model
In this study, we used geometric morphometrics to understand the effect of bolus shape on penetration and aspiration in infants with and without RLN lesion. We hypothesized (1) that geometric bolus properties are related to airway protection outcomes and (2) that in infants with RLN lesion, the relationship between geometric bolus properties and dysphagia is changed. In five infant pigs, dysphagia in 188 swallows was assessed using the Infant Mammalian Penetration –Aspiration Scale (IMPAS). Using images from high-speed VFSS, bolus shape, bolus area, and tongue outline were quantified digitally. Bolus shape was analyz...

Modulation of Upper Esophageal Sphincter (UES) Relaxation and Opening During Volume Swallowing
AbstractUES opening occurs following cricopharyngeus deactivation and submental muscle contraction causing hyolaryngeal elevation and UES distraction. During impedance manometry, the inverse of impedance (admittance) can be used to measure bolus presence and infer UES opening. We hypothesized that the temporal relationship between UES relaxation, opening and hyolaryngeal elevation would change with increasing bolus volume. Simultaneous intramuscular cricopharyngeal (CP) electromyography (EMG), surface submental EMG (SM-EMG), and high-resolution impedance manometry were recorded in eight (aged 27  ± 7 ...
