Spatial Characteristics of Jaw Movements During Chewing in Children with Cerebral Palsy: A Pilot Study
This study compared jaw motion between children with cerebral palsy (CP) and their typically-developing (TD) peers during chewing. The jaw movements of 11 children with spastic CP (GMFCS levels II –V) all of whom were exclusively oral feeders with no reported clinical issues with feeding [mean age = 7.49 (2.30) years; 7 males, 4 females] and 11 age- and sex-matched TD peers [mean age = 7.54 (2.35) years] were recorded using optical motion capture. Participants chewed five trials of thre e different consistencies, including puree, mechanical soft, and solid. For each chewing sequence, the path dist...

LVC Timing in Infant Pig Swallowing and the Effect of Safe Swallowing
AbstractRecurrent laryngeal nerve (RLN) injury in neonates, a complication of head and neck surgeries, leads to increased aspiration risk and swallowing dysfunction. The severity of resulting sequelae range from morbidity, such as aspiration pneumonia, to mortality from infection and failure to thrive. The timing of airway protective events including laryngeal vestibule closure (LVC) is implicated in aspiration. We unilaterally transected the RLN in an infant pig model to observe changes in the timing of swallowing kinematics with lesion and aspiration. We recorded swallows using high-speed video-fluoroscopic swallow studi...

Development of Pyriform Sinus Suctioning Programs for Aspiration Pneumonia Prevention During the Acute Stroke
AbstractAspiration due to dysphagia is a factor associated with pneumonia during acute stroke. In such cases, it is likely that secretions in the pyriform sinuses enter the laryngeal inlet. The present study was based on the idea that it is possible to reduce aspiration pneumonia by periodically suctioning and removing such secretions (pyriform sinus suctioning), a study was conducted in a single facility. The incidence of pneumonia as a dependent variable was compared between before (control) and after (intervention group) intervention with pyriform sinus suctioning as an independent variable. With a view of unifying the ...

Accuracy of a Laryngopharyngeal Endoscopic Esthesiometer (LPEER) for Evaluating Laryngopharyngeal Mechanosensitivity: A Validation Study in a Prospectively Recruited Cohort of Patients
AbstractRecent studies have shown an association between alterations in laryngopharyngeal mechanosensitivity (LPMS) and dysphagia, obstructive sleep apnea, and chronic cough hypersensitivity syndrome. A previous reliability study of a new laryngopharyngeal endoscopic esthesiometer and rangefinder (LPEER) showed high intra- and inter-rater reliability; however, its accuracy has not been tested. We performed an accuracy study of the LPEER in a prospectively and consecutively recruited cohort of 118 patients at two tertiary care university hospitals. Most of the patients were suffering from dysphagia, and all of them underwen...

How Swallow Pressures and Dysphagia Affect Malnutrition and Mealtime Outcomes in Long-Term Care
AbstractMalnutrition is a major cause of hospitalization for residents of long-term care facilities (LTC). Dysphagia is thought to contribute to malnutrition. Tongue weakness is suggested to predict poor food intake, longer meals, and dysphagia. We explored the relationships between tongue strength, dysphagia, malnutrition and mealtime outcomes in LTC residents. Data were collected from 639 LTC residents (199 male), aged 62 –102 (mean 87). Maximum isometric tongue pressures (MIPs) and saliva swallow pressures (MSPs) were measured using the Iowa Oral Performance Instrument. Participants also completed the Screening To...

The Influence of Oropalatal Dimensions on the Measurement of Tongue Strength
AbstractTongue strength is routinely evaluated in clinical swallowing evaluations since lingual weakness is an established contributor to dysphagia. Tongue strength may be clinically quantified by the maximum isometric tongue pressure (MIP) generated by the tongue against the palate; however, wide ranges in normal performance remain to be fully explained. Although orthodontic theory has long suggested a relation between lingual function and oral cavity dimensions, little attention has been given to the potential influence of oral and palatal structure(s) on healthy variance in MIP generation. Therefore, anterior and poster...

Measurement of Pharyngo-laryngeal Volume During Swallowing Using 320-Row Area Detector Computed Tomography
This study aimed to (1) evaluate changes in bolus and air volumes in the pharyngo-laryngeal cavity during swallowing and (2) determine how differences in these volumes during swallowing are influenced by bolus amount using 320-row area detector computed tomography (320-ADCT).

Measurement of the Maximum Frequency of Electroglottographic Fluctuations in the Expiration Phase of Volitional Cough as a Functional Test for Cough Efficiency
AbstractThe hypotheses of the present study were that the maximum frequency of fluctuation of electroglottographic (EGG) signals in the expiration phase of volitional cough (VC) reflects the cough efficiency and that this EGG parameter is affected by impaired laryngeal closure, expiratory effort strength, and gender. For 20 normal healthy adults and 20 patients diagnosed with unilateral vocal fold paralysis (UVFP), each participant was fitted with EGG electrodes on the neck, had a transnasal laryngo-fiberscope inserted, and was asked to perform weak/strong VC tasks while EGG signals and a high-speed digital image of the la...

Reflections on Clinical and Statistical Use of the Penetration-Aspiration Scale
AbstractThe 8-point Penetration-Aspiration Scale (PAS) was introduced to the field of dysphagia in 1996 and has become the standard method used by both clinicians and researchers to describe and measure the severity of airway invasion during swallowing. In this article, we review the properties of the scale and explore what has been learned over 20  years of use regarding the construct validity, ordinality, intervality, score distribution, and sensitivity of the PAS to change. We propose that a categorical revision of the PAS into four levels of increasing physiological severity would be appropriate. The article concl...

Swallowing Disorders in Schizophrenia
AbstractDisorders of swallowing are poorly characterized but quite common in schizophrenia. They are a source of considerable morbidity and mortality in this population, generally as a result of either acute asphyxia from airway obstruction or more insidious aspiration and pneumonia. The death rate from acute asphyxia may be as high as one hundred times that of the general population. Most swallowing disorders in schizophrenia seem to fall into one of two categories, changes in eating and swallowing due to the illness itself and changes related to psychotropic medications. Behavioral changes related to the illness are poor...
