The Mayo Dysphagia Questionnaire-30: Documentation of Reliability and Validity of a Tool for Interventional Trials in Adults with Esophageal DiseaseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The aim of this study was to develop the Mayo Dysphagia Questionnaire-30 Day (MDQ-30), a tool to measure esophageal dysphagia, by adapting items from validated instruments for use in clinical trials, and assess its feasibility, reproducibility, and concurrent validity. Outpatients referred to endoscopy for dysphagia or seen in a specialty clinic were recruited. Feasibility testing was done to identify problematic items. Reproducibility was measured by test–retest format. Concurrent validity reflects agreement between information gathered in a structured interview versus the patients’ written res...

Sensory Transcutaneous Electrical Stimulation Improves Post-Stroke Dysphagic PatientsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Oropharyngeal dysphagia is frequent in stroke patients and increases mortality, mainly because of pulmonary complications. We hypothesized that sensitive transcutaneous electrical stimulation applied submentally during swallowing could help rehabilitate post-stroke oropharyngeal dysphagia by improving cortical sensory motor circuits. Eleven patients were recruited for the study (5 females, 68 ± 11 years). They all suffered from recent oropharyngeal dysphagia (>eight weeks) induced by a hemispheric (n = 7) or brainstem (n = 4) stroke, with pharyngeal residue and...

Computer-Assisted Assessment of Hyoid Bone Motion from Videofluoroscopic Swallow StudiesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe a computerized image analysis program designed to objectify one component of the swallow study, the movement of the hyoid bone. Hyoid motion has been shown to be different in dysphagic versus non-dysphagic patients. Reduced hyoid elevation is also considered a risk factor for aspiration; however, there has not been much work done on actually quantifying hyoid motion and associating it with other aspects of the swallow study. The clinician is prompted to define the hyoid bone in a calibration frame, and the system then tracks that region of interest throughout the rest of the study. This system shows strong...

Fluoroscopic Surrogate for Pharyngeal Strength: The Pharyngeal Constriction Ratio (PCR)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective of the current study was to evaluate the correlation between PCR and PP in 25 patients undergoing simultaneous fluoroscopy and pharyngeal manometry. The effect of the manometric catheter on PCR was also investigated. The correlation between the PCR and averaged pharyngeal clearing pressures was −0.72 (p < 0.001). All patients with a PCR > 0.25 had a PP < 60 mmHg. PCR did not differ significantly as a consequence of the manometric catheter. Results suggest the utility of an objective fluoroscopic measure in assessing pharyngeal strength when manometry may not ...

Oropharyngeal Dysphagia in Infants and Children with Infantile Pompe DiseaseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Pompe disease is a rare genetic progressive neuromuscular disorder. The most severe form, infantile Pompe disease, has historically resulted in early mortality, most commonly due to cardiorespiratory failure. Treatment with enzyme replacement therapy (ERT) using alglucosidase alfa (Myozyme®) has extended the lifespan of individuals with this disease. With the introduction of ERT and the resultant improved survival, dysphagia is being encountered clinically with increasing regularity though systematic data remain unavailable. We retrospectively studied the oropharyngeal swallowing of 13 infants and ...

Abstract The aim of this work was to assess the efficacy of external myotomy of the upper esophageal sphincter (UES) for oropharyngeal dysphagia. In the period 1991–2006, 28 patients with longstanding dysphagia and/or aspiration problems of different etiologies underwent UES myotomy as a single surgical treatment. The main symptoms were difficulties in swallowing of a solid-food bolus, aspiration, and recurrent incidents of solid-food blockages. Pre- and postoperative manometry and videofluoroscopy were used to assess deglutition and aspiration. Outcome was defined as success in the case of complete relief...

Initiation and Duration of Laryngeal Closure During the Pharyngeal Swallow in Post-Stroke PatientsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract As a bolus enters the pharynx during the swallow, the airway is protected by laryngeal closure, a process characterized by approximation of the vocal folds plus approximation of the arytenoid cartilages to the base of the epiglottis. The purpose of this study was to measure initiation of laryngeal closure (ILC) and laryngeal closure duration (LCD) in three groups of subjects: (1) ten stroke patients who aspirated before and during the swallow (aspirators), (2) ten stroke patients who did not aspirate (nonaspirators), and (3) ten normal control subjects. Means and standard deviations of ILC and LCD w...

Supranuclear Control of SwallowingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Swallowing is an act requiring complex sensorimotor integration. Using a variety of methods first used to study limb physiology, initial efforts to study swallowing have yielded information that multiple cortical and subcortical regions are active participants. Not surprisingly, the regions activated appear to overlap those involved in both oral and nonoral motor behaviors. This review offers a perspective that considers the supranuclear control of swallowing in light of these physiological similarities.

Dysphagia in Head and Neck Cancer Patients Treated with ChemoradiotherapyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Dysphagia is a very common complaint of head and neck cancer patients and can exist before, during, and after chemoradiotherapy. It leads to nutritional deficiency, weight loss, and prolonged unnatural feeding and also has a major potential risk for aspiration. This has a significant negative impact on the patient’s entire quality of life. Because treatment of dysphagia in this setting is rarely effective, prevention is paramount. Several strategies have been developed to reduce dysphagia. These include swallowing exercises, treatment modification techniques such as intensity-modulated radiotherap...

Immediate Effects of Thermal–Tactile Stimulation on Timing of Swallow in Idiopathic Parkinson’s DiseaseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Oropharyngeal dysphagia frequently presents in people with idiopathic Parkinson’s disease (IPD). Clinical sequelae of dysphagia in this group include weight loss and aspiration pneumonia, the latter of which is the leading cause of hospital admissions and death in IPD. Thermal–tactile stimulation (TTS) is a sensory technique whereby stimulation is provided to the anterior faucial pillars to speed up the pharyngeal swallow. The effects of TTS on swallowing have not yet been investigated in IPD. The aim of this study was to investigate the immediate effects of TTS on the timing of swallow in a coh...

Abstract Reduced maximal hyoid excursion has been suspected as one of the primary physiologic causes of aspiration after a stroke. Vertical and anterior displacement of hyoid excursion is critical to epiglottic closure for airway protection and the opening of the upper esophageal sphincter (UES). Without these carefully timed and well-executed components, the bolus cannot pass safely through the pharynx. The purpose of this study was to evaluate vertical and anterior displacement of the hyoid bone during oropharyngeal swallowing in two groups of subjects: (1) 16 stroke patients who aspirate before or during ...

Simple Swallowing Provocation Test Has Limited Applicability as a Screening Tool for Detecting Aspiration, Silent Aspiration, or PenetrationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract A number of tests for evaluating dysphagia without using videofluoroscopic examination of swallowing (VF) or videoendoscopic evaluation of swallowing (VE) have been developed. The simple swallowing provocation test (SSPT) is unique because it is performed while in a supine position and does not require the patient’s cooperation. However, whether the SSPT detects aspiration or penetration correctly is unclear because its validity determined by VF or VE has not been evaluated. Therefore, we determined the sensitivity, specificity, and predictive accuracy of SSPT followed by VF in 45 patients. The se...

A Mouse Model of Pharyngeal Dysphagia in Amyotrophic Lateral SclerosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract We recently established that the SOD1-G93A transgenic mouse is a suitable model for oral-stage dysphagia in amyotrophic lateral sclerosis (ALS). The purpose of the present study was to determine whether it could serve as a model for pharyngeal-stage dysphagia as well. Electrophysiological and histological experiments were conducted on end-stage SOD1-G93A transgenic mice (n = 9) and age-matched wild-type (WT) littermates (n = 12). Transgenic mice required a twofold higher stimulus frequency (40 Hz) applied to the superior laryngeal nerve (SLN) to evoke swallowing compared wit...

Anthropometric and Demographic Correlates of Dual-Axis Swallowing Accelerometry Signal Characteristics: A Canonical Correlation AnalysisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Swallowing accelerometry has been proposed as a potential minimally invasive tool for collecting assessment information about swallowing. The first step toward using sounds and signals for dysphagia detection involves characterizing the healthy swallow. The purpose of this article is to explore systematic variations in swallowing accelerometry signals that can be attributed to demographic factors (such as participant gender and age) and anthropometric factors (such as weight and height). Data from 50 healthy participants (25 women and 25 men), ranging in age from 18 to 80 years and with approxi...

Accuracy of Clinical Judgment of the Chin-Down Posture for Dysphagia During the Clinical/Bedside Assessment as Corroborated by Videofluoroscopy in Adults with Acute StrokeEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Speech-language pathologists tend to rely on the noninstrumental swallowing evaluation in making recommendations about a patient’s diet and management plan. The present study was designed to examine the sensitivity and specificity of the accuracy of using the chin-down posture during the clinical/bedside swallowing assessment. In 15 patients with acute stroke and clinically suspected oropharyngeal dysphagia, the correlation between clinical and videofluoroscopic findings was examined. Results identified that there is a difference in outcome prediction using the chin-down posture during the clinica...

A Randomized Study Comparing the Shaker Exercise with Traditional Therapy: A Preliminary StudyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Seven institutions participated in this small clinical trial that included 19 patients who exhibited oropharyngeal dysphagia on videofluorography (VFG) involving the upper esophageal sphincter (UES) and who had a 3-month history of aspiration. All patients were randomized to either traditional swallowing therapy or the Shaker exercise for 6 weeks. Each patient received a modified barium swallow pre- and post-therapy, including two swallows each of 3 ml and 5 ml liquid barium and 3 ml barium pudding. Each videofluorographic study was sent to a central laboratory and digitized in o...

Viscosity in Infant Dysphagia Management: Comparison of Viscosity of Thickened Liquids Used in Assessment and Thickened Liquids Used in TreatmentEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The purpose of this study was to investigate comparability of viscosity of liquids used in assessment and treatment of infants with dysphagia. Goals of this study were as follows: (1) Establish baseline viscosity values for (a) the commercial barium assessment liquids of varying thicknesses and (b) clinically typical infant formula thickened with varied thickeners. (2) Compare the baseline viscosities of the various liquids for correlation of values. We attempted to mimic real-world situations and recreate clinical assessment and treatment conditions. We also identified and made every effort to cont...

Validation of ICD-9 Code 787.2 for Identification of Individuals with Dysphagia from Administrative DatabasesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The aim of this study was to determine the accuracy of dysphagia coding using the International Classification of Diseases version 9 (ICD-9) code 787.2. We used the administrative database of a tertiary hospital and sequential videofluorographic swallowing study (VFSS) reports for patients admitted to the same hospital from January to June 2007. The VFSS reports were abstracted and the hospital’s database was queried to abstract the coding associated with the admission during which the VFSS was performed. The VFSS and administrative data were merged for data analysis. Dysphagia was coded (using co...

Brain Stem Control of the Phases of SwallowingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The phases of swallowing are controlled by central pattern-generating circuitry of the brain stem and peripheral reflexes. The oral, pharyngeal, and esophageal phases of swallowing are independent of each other. Although central pattern generators of the brain stem control the timing of these phases, the peripheral manifestation of these phases depends on sensory feedback through reflexes of the pharynx and esophagus. The dependence of the esophageal phase of swallowing on peripheral feedback explains its absence during failed swallows. Reflexes that initiate the pharyngeal phase of swallowing also ...

Patient Dose During Videofluoroscopy Swallowing Studies in a Hong Kong Public HospitalEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract A videofluoroscopy swallowing study (VFSS) is a major tool in diagnosing swallowing disorders. Like all other medical examinations that involve irradiation, patient dosage is a major concern. Cerebrovascular accident (CVA) and nasopharyngeal carcinoma (NPC) have been two of the most common indicating pathologies for VFSS studies. The goals of this study were to determine the mean dose area product (DAP) value and fluoroscopic time for VFSS examinations in Tuen Mun Hospital, to compare the result with the dose reference level of other similar studies, and to document the results with respect to the v...
