OBJECTIVES/HYPOTHESIS: Deformities of the anterior cervical spine are an established cause of dysphagia. Whereas osteophytes and spinal fusion hardware have been reported to alter bolus flow and contribute to swallowing dysfunction, the relationship between abnormal spine curvature and swallowing dysfunction is not established. The purpose of this investigation was to evaluate the association between cervical kyphosis and objective measures of swallowing dysfunction on videofluoroscopy...

Hyoid and laryngeal movements contribute to laryngeal vestibule closure and upper esophageal sphincter opening during swallowing. Evidence of an internal sensorimotor scaling system allowing individuals to achieve these functional goals is lacking. In speech, speakers adjust their articulatory movement magnitude according to the movement distance required to reach an articulatory target for intelligible speech. We investigated if swallowing is similar in that movement amplitude may be scaled by the functional goal for airway protection during swallowing, rather than by head and neck size...

The Frazier Free Water Protocol was developed with the aim of providing patients with dysphagia an option to consume thin (i.e. unthickened) water in-between mealtimes. A systematic review was conducted of research published in peer-reviewed journals. An electronic search of the EMBASE, CINAHL and MEDLINE databases was completed up to July 2016. A total of 8 studies were identified for inclusion: 5 randomised controlled trials, 2 cohort studies with matched cases and 1 single group pre-post intervention prospective study...

In this study, an in vitro device that mimics the oral phase of swallowing is calibrated using in vivo measurements. The oral flow behavior of different Newtonian and non-Newtonian solutions is then investigated in vitro, revealing that shear-thinning thickeners used in the treatment of dysphagia behave very similar to low-viscosity Newtonian liquids during active swallowing, but provide better control of the bolus before the swallow is initiated. A theoretical model is used to interpret the experimental results and enables the identification of two dynamical regimes for the flow of the bolus: first, an inertial regime of constant acceleration dependent on the applied force and system inertia, possibly followed by a viscous regime in which the viscosity governs the constant velocity of the bolus...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, no investigation had sought to determine if swallowing impairments were present in persons with PWS...

Swallowing involves complex coordination of the neuromuscular anatomy and physiology of the oropharynx and esophagus, controlled by the enteric and central nervous systems. Dysphagia is classified as either oropharyngeal or esophageal and results from mechanical or structural disturbances. Videofluoroscopy, fiberoptic endoscopic evaluation of swallowing, barium swallow, manometry, and endoscopy are common modalities utilized in diagnosis, but none is as important as a patient's history. Functional dysphagia is a diagnosis of exclusion and is based on Rome criteria...

Submental surface electromyography (ssEMG) visual biofeedback is widely used to train swallowing maneuvers. This study compares the effect of ssEMG and videofluoroscopy (VF) visual biofeedback on hyo-laryngeal accuracy when training a swallowing maneuver. Furthermore, it examines the clinician's ability to provide accurate verbal cues during swallowing maneuver training. Thirty healthy adults performed the volitional laryngeal vestibule closure maneuver (vLVC), which involves swallowing and sustaining closure of the laryngeal vestibule for 2 s...

: The assessment of swallowing function is important for the prevention of aspiration pneumonia. We developed a new swallowing monitoring system that uses respiratory flow, swallowing sound, and laryngeal motion. We applied this device to 11 healthy volunteers and 10 patients with dysphagia. Videofluoroscopy (VF) was conducted simultaneously with swallowing monitoring using our device. We measured laryngeal rising time (LRT), the time required for the larynx to elevate to the highest position, and laryngeal activation duration (LAD), the duration between the onset of rapid laryngeal elevation and the time when the larynx returned to the lowest position...

BACKGROUND: Oesophageal abnormalities are common findings in a speech-language therapy videofluoroscopy clinic. Fluoroscopic screening involving oropharynx alone fails to identify these patients. Oesophageal screening as an adjunct to videofluoroscopy is gaining popularity. Yet currently, little is known about the reliability of speech and language therapists' judgement of the oesophageal phase. AIM: To measure the inter-rater reliability of oesophageal abnormality judgement in speech and language therapists during upright videofluoroscopy...

BACKGROUND: The state of the art for correcting velopharyngeal insufficiency (VPI) is a surgical procedure which is customized according to findings on imaging procedures: multiplanar videofluoroscopy (MPVF) and flexible videonasopharyngoscopy (FVNP). Recently, the use of MPVF has been challenged because of the potential risk of using ionizing radiation, especially in children. OBJECTIVE: To study whether using a protocol for performing MPVF can effectively decrease radiation dose in patients with VPI while providing useful information for planning surgical correction of VPI in combination with FVNP...

BACKGROUND: Acute cerebral stroke is a common problem that is frequently associated with dysphagia resulting in an increased risk of aspiration pneumonia, complication, and mortality. METHODS: A literature review was carried out using the search terms 'stroke unit and endoscopy', 'stroke unit and dysphagia', and 'stroke unit and gastroenterology'. RESULTS: Only few papers focus on the role of endoscopy in stroke units. One major role is the early detection of dysphagia by flexible endoscopic evaluation of swallowing (FEES)...

Determining intrabolus pressure (IBP) at the upper esophageal sphincter (UES) and in the esophagus has given compelling evidence that IBP can be a predictor for swallowing dysfunction. Studies have looked most superiorly at the low hypopharynx region but there has been no inquiry into what IBP measures throughout the entire pharynx can tell us. We present a study to describe the pressures within and surrounding the moving bolus throughout the pharynx and into the UES. Simultaneous high-resolution manometry (HRM) and videofluoroscopy were performed in ten healthy subjects swallowing ten 10 mL thin-liquid barium boluses...

BACKGROUND: Head and neck cancer treatment has developed over the last decade, with improved mortality and survival rates, but the treatments often result in dysphagia (a difficulty in swallowing) as a side effect. This may be acute, resolving after treatment, or remain as a long-term negative sequela of head and neck cancer (HNC) treatment. Interventions to counteract the problems associated with dysphagia include swallowing exercises or modification of diet (bolus texture, size), or both...

OBJECTIVES: To compare videofluoroscopy that included a tablet test with impedance planimetry (EndoFLIP(®)) for the evaluation of oesophageal stenosis in patients with dysphagia. METHODS: In 56 patients, videofluoroscopic examinations following the transit of a 14-mm tablet were retrospectively reviewed and correlated with impedance planimetry findings, a catheter-based method using impedance planimetry to display the oesophageal diameter estimates. Additional findings assessed were the occurrence of symptoms during tablet passage and evaluation of oesophageal motility...

The Eating Assessment Tool-10 (EAT-10) represents a validated, easy to administer patient report dysphagia severity scale. Although its ability to detect swallowing impairment has been investigated in other patient populations, the utility of this instrument in individuals with head and neck cancer (HNC) has not been studied. The aim of the current investigation was to determine the relationship between patient ratings of swallowing impairment (EAT-10) and objective clinical ratings of swallow physiology in individuals with HNC...
