A custom-made electrode connected to a flexible stainless-steel coil spring tube was introduced into the pharyngeal region through the nasal cavity and placed against the posterior wall of the oropharynx. Surface electrodes placed over the suprahyoid muscles recorded the electromyogram during swallowing. Swallowing reflexes were induced several times by 30 s of repetitive electrical pulse stimulation (intensity: 0.2–1.2 mA, frequency: 10–70 Hz, pulse duration: 1.0 ms). The onset latency of the swallowing reflex was measured over the ...

We also sought to determine if respiratory system recoil is responsible for generating the pressure. Ten healthy volunteers underwent direct DPsub measurement via percutaneous puncture of the cricothyroid membrane. Simultaneous DPsub and nasal airflow volumes were recorded while participants swallowed calibrated boluses over a wide range of lung volumes. Body plethysmography was used to determine functional residual capacity and residual volume. A custom respiratory recoil measurement system was used to measure recoil pressures. Regression analysis of lung volume o...

Three different electrode positions were applied in random order per subject. For each electrode position, the electrical current was respectively turned “on” and “off” in random order. Temporal, spatial, and visuoperceptual variables were scored by experienced raters who were blinded to the group, electrode position, and status (on/off) of the electrical current. Interrater and interrater reliabilities were calculated. Only a few signific...

Its pathophysiology implies an impairment of esophageal inhibitory neural function. Using conventional manometry, DES was defined by the presence of simultaneous esophageal contractions. With the introduction of high-resolution manometry and esophageal pressure topography (EPT) in clinical practice, rapidly propagated contractions are nonspecific of esophageal spasm. Hence, a more physiological and clinically relevant definition was proposed. Distal latency (DL) measures the period of inhibition that precedes contraction in the distal esophagus immediately proximal to the esophagogastric junction (EGJ). Premature contractions, defined as reduced D...

We used high-resolution manometry (HRM) to quantify the effects of these maneuvers on pressure and timing characteristics. Fourteen normal subjects swallowed multiple, 5-ml water boluses using three techniques: normal swallow, effortful swallow, and the Mendelsohn maneuver. Maximum pressure, rate, duration, area integral, and line integral were determined for the velopharynx and tongue base. Minimum pressure, duration of pressure-related change, duration of nadir pressure, maximum preopening and postclosure pressure, area integral, and line integral were recorded for the upper esophageal sphincter (UES). Area and line integrals of the velopharyngeal pressure c...

Experiments simulated a possible clinical scenario whereby saliva enters a cup and contaminates a drink. Citric acid (E330) was added to water to produce a controlled range of pH from 3.0 to 7.0, and several commercially available drinks with naturally low pH were investigated. When saliva was added to thickened water, viscosity was reduced to less than 1% of its original value after 10–15 min. However, lowering pH systematically slowed the reduction in viscosity attributable to saliva. At pH 3.5 and below, saliva was found to have no significant effect on viscosity. The pH of drinks in this study ranged from 2.6 for Coca Cola to 6.2 for black coffee....

Patients report coughing, choking, and bolus sticking in the pharynx. Myotomy has been the treatment of choice, with variable success reported. We sought to determine underlying causes of dysphagia in IM patients using instrumental evaluation. Eighteen subjects participated in the study: four with DM, six with PM, and eight with IBM. They underwent simultaneous videofluoroscopy and manometry, yielding 214 swallows for analysis regarding function of the upper esophageal sphincter (UES), swallow initiation, hyolaryngeal excursion, and pharyngeal residue. Penetration and aspiration were also recorded. UES failed to r...

We tested the null hypothesis of no significant influence of oral maneuver and the use of oral screens on tongue coordination and position during deglutition in 29 subjects (age = 6–16; mean = 9.69 years; 13/16 female/male) with habitual open-mouth posture using intraoral polysensography. The target parameters for swallowing were swallowing-associated nasal airflow interruption (NAI) and coordination of tongue–palate contact during NAI. Conventional myofunctional maneuvers could be facilitated and made more efficient, in terms of increa...

The approach involved a dual-task, reaction time (RT) paradigm using ten participants with Parkinson’s disease. Single-task baseline measures were obtained for durations of the anticipatory phase and oropharyngeal phase of swallowing and RTs were obtained for nonword auditory stimuli. A dual-task then required participants to swallow 5 ml of water from an 8-oz. cup while listening for a target nonword presented auditorily during the anticipatory or oropharyngeal phase. Target stimuli were randomized across baseline and dual-task trials. Durations of the anticipatory ...

These rehabilitation exercises are believed to affect the peripheral and central nervous system at various levels. However, few studies have examined healthy subjects’ brain activity while performing oral exercises used in dysphagia rehabilitation. The current study sought to measure brain activation during oral exercises in healthy subjects using functional magnetic resonance imaging (fMRI). Lip-pursing and lip-stretching, tongue protrusion, lateral tongue movement, and oral ball-rolling were selected as tongue and lip exercise tasks. The tasks were performed by eight healthy subjects, and ...

He was seen previously by other physicians and diagnosed as hypothyroidism. With thyroid stimulating hormone in normal range, tongue biopsy revealed primary systemic amyloidosis. Amyloidosis is the most common cause of macroglossia. Primary systemic amyloidosis should be suspected when laboratory does not support hypothyroidism especially if the enlarged tongue is firm and additional findings are present.

Video fluoroscopic swallow study (VFSS) parameters evaluated included the volume of residue in the vallecular pouch and the pyriform sinus, the Rosenbek penetration-aspiration scale (PAS), and the swallowing function scoring system (SFSS). By VFSS findings, patients were classified into a mild or severe dysphagia group. Nine of 17 patients showed voice change. SFSS scores were 0 in 2 patients, 3 in 1 patient, 4 in 1 patient, 5 in 1 patient, and 6 in 12 patients. PAS scores were 1 in 8 pa...

The GF Strong Water Protocol (GFSWP) is an interdisciplinary initiative, with roles and accountabilities specified for different members of the interprofessional health-care team. Rules of the water protocol specify mode of water access (independent, supervised), the implementation of any safe swallowing strategies recommended on the basis of the patient’s videofluoroscopy, and procedures for evaluating and addressing oral care needs. Trial implementation of the water protocol in 15 participants showed that they remained free of adverse events, including pneumonia, over the course of an initial 14-day trial and continuin...

The approach involved a dual-task, reaction time (RT) paradigm in ten healthy, nonimpaired participants. Baseline measures were obtained of the duration of the anticipatory phase and of the oropharyngeal phase of swallowing and the RTs to nonword auditory stimuli. A dual-task then required participants to swallow 5 ml of water from an 8-oz. cup while listening for a target nonword presented auditorily during the anticipatory or the oropharyngeal phase. Target stimuli were randomized across baseline and dual-task trials. Duration of the anticipatory phase and of the oropharyngeal phase of swallowing and duration of the RT baseline trial and of the dual-task trial were determined. Result...

The study was a cross-sectional analysis of human cricopharyngeus muscles. Twenty-seven muscles obtained from autopsies of men and women ranging in age from 28 to 92 years were analyzed with the Picrosirius method, oxidized Weigert resorcin-fuchsin, immunohistochemistry, and image analysis. Collagen had the highest density among the analyzed components. Elastic fibers surrounded each muscle cell; they were aligned longitudinally by their long axis and associated with traversing fibers, thereby forming a fiber network with embedded ...

The mylohyoid (MH) muscle has been considered to be a “leading muscle” according to previous studies, but the functional role of the digastric (DIG) muscle in the swallowing reflex remains unclear. In the present study, therefore, the activities of single units of MH and DIG neurons were recorded extracellularly, and the functional involvement of these neurons in the swallowing reflex was investigated. The experiments were carried out on eight adult male Japanese white rabbits anesthetized with ureth...

Using a single-group consecutively referred case series, a total of 2,650 participants underwent fiberoptic endoscopic evaluation of swallowing between August 2003 and December 2007. Main outcome measures included overall incidence of VFI and aspiration status, with specific emphasis on age, gender, etiology and pharyngeal phase bolus flow characteristics, and side of VFI (right, left, or bilateral). These data were compared to and then combined with the original study (n = 1,452) for a total of 4,102 participants. Results indicated that the incidence of VFI was 4.3% (112/2,650), i.e., 27% (3...

However, the true effect of PEG use on weight maintenance and its potential impact on long-term dysphagia outcomes have not been adequately studied. This retrospective study looked at swallowing-related outcomes among patients who received prophylactic PEG vs. those who did not, and among patients who maintained oral diets vs. partial oral diets vs. those who were nil per os (NPO). Outcomes were assessed at the end of RT and at 3, 6, and 12 months post RT. A comprehensive review of patients’ medical charts for a 6-year period yielded 59 subjects with complete data. Results showed no dif...

However, utilization of metal stents for benign esophageal diseases has been controversial. Given the availability of removable, fully covered, self-expandable metal stents (RFCSEMSs), this study was undertaken to evaluate the effectiveness and safety of RFCSEMSs in patients with refractory benign esophagogastric anastomotic strictures. Twenty-four patients with RFCSEMSs were enrolled in this study. All patients had undergone endoscopic Savary-Gilliard bougie dilatation five times or more but there was no significant improvement in symptoms. For all 24 patients, the symptom of dysphagia was alleviated significantly while the stent was in place and for a short time after st...

Seventeen people with pharyngeal delay attended for videofluoroscopy (VFSS). Outcome measures were oral transit time (OTT), pharyngeal transit time (PTT), stage transition duration (STD), initiation of the pharyngeal swallow (IPS), penetration-aspiration scale (PENASP), and pharyngeal retention (PR). A modification of Quartermaster Hedonic Scale (AQHS) was employed to assess palatability of the CTL. CTL vs. NCTL significantly decreased penetration and aspiration on 5-ml (P = 0.028) and 10-ml (P = 0.037) swallows. CTL had no significant effect...

We predicted that sequential swallowing would be accompanied by prolonged breath-holding in most cases, and that this would be followed by a recovery phase during which ventilation would increase for a brief period. Results showed that not only did healthy participants increase ventilation after sequential swallowing, they also experienced breathing discomfort (dyspnea) despite the fact that they usually continued to breathe during the swallowing sequence. Given that these effects are observable in young, healthy adults, it seems reasonable to assume that individuals with respiratory and/or neurological compromise would also have an increased drive t...

Presentation of orally chemesthetic input has been theorized to stimulate a faster, stronger swallow. We measured differences in peak linguapalatal swallowing pressures, pressure durations, and pressure adjustments in response to two volumes of water and carbonation (in Schweppes® Club Soda) and carbonation + gingerol (in Reed’s Extra Ginger Brew) in 20 young adult women. There was a main effect of stimulus on linguapalatal swallowing pressure, F(6,74) = 6.247, p = 0.000, hp2 = 0.536 (Reed’s Extra Ginger Brew > Schweppes Club Soda > water).

The aim of this study was to evaluate the safety and efficacy of repeated endoscopic dilatation for OPMD over a 15-year period. All patients seen at our Regional Swallowing Clinic with OPMD confirmed by genetic analysis were included. Cricopharyngeal dilatation was performed as an outpatient procedure using a wire-guided 18-mm (54 Fr) Savary-Gilliard bougie with the patient under sedation. Patients were offered repeat endoscopic dilatation when symptoms recurred. Symptom severity prior to initial dilatation and at follow-up was evaluated using the Sydney Swallow Questionnaire (SSQ). Nine patients (7 ...

The purpose of this study was to investigate how drinking behavior in terms of drinking speed and bolus size differs between young and older adults following instructions to change drinking rate. Thirty young (mean age 24.7 years) and 30 older (mean age 66.9 years) healthy female participants were recruited. All participants drank water under different drinking instructions: “as they normally would”, “as quickly as is comfortably possible”, and “slowly”. Results showed that when asked to drink quickly, both age groups increased drinking speed to a similar extent. When ...

VFSSs were performed with thick and thin liquid using modified Logemann methods. The patients were grouped according to whether their VCP was of central or peripheral origin, and the VFSS findings of the groups were compared. The patients showed oral phase dysfunction and pharyngeal dysfunction, especially when the cause was of central origin. Oral phase abnormalities were found in 13 patients and pharyngeal phase abnormalities were found in all patients, including penetration in 20 patients and aspiration in 14 patients. Improper lip closure (LC) and bolus formation (BF) and a delay in triggering pharyn...

This negative flow, referred to as “SNIF,” or swallow noninspiratory flow, occurs at the onset of airway reestablishment at the conclusion of the oropharyngeal swallow. Using simultaneous digital video fluoroscopic and nasal respiratory airflow recordings on 82 healthy adults (21–97 years old), the objectives of this study were to determine (1) the frequency of occurrence of SNIF during a 5-ml natural cup-drinking task, (2) differences in SNIF occurrence by age group, and (3) the temporal relationship between SNIF and other swallowing events. Results revealed that for most pa...

Inter- and intrarater reliabilities were also estimated for hyoid and laryngeal displacement measurements across conditions. The use of different calibration referents did not contribute significantly to variability in measures of hyoid and laryngeal displacement but image rotation affected horizontal measures for both structures. Inter- and intrarater reliabilities were high. Using the 95% confidence interval as the error index, measurement error was estimated to range from 2.48 to 3.06 mm. These results address procedural decisions for measuring hyoid and laryngeal displacement in video fluoroscopic swallowing studies...

Concurrently, all patients were screened for gastroesophageal reflux disease (GERD) as an associated cause or aggravating factor in MTD. The study’s design was a prospective case-control study. Fourteen patients with MTD (mean age = 40.2 years, range = 22–62 years) and 14 adult controls (mean age = 33.9 years, range = 23–58 years) were studied.

To determine the prevalence of endoscopic findings in patients with dysphagia and whether findings differ in regard to age, gender, ethnicity, and repeat procedure. This was a retrospective study using a national endoscopic database (CORI). A total of 30,377 patients underwent esophagogastroduodenoscopy (EGD) for dysphagia of which 4,202 patients were repeat endoscopies.

The reported case was a potentially life-threatening complication due to mucosal edema following esophagogastroduodenoscopy (EGD). A 37-year-old man, suffering from severe DPU and chronic spontaneous urticaria, had undergone EGD due to dyspeptic symptoms. A few hours after the EGD procedure, the patient showed both dysphagia and dyspnea. A physical examination indicated massive tongue base and pharynx edema. We suggest that these symptoms were most likely due to the pressure exerted by EGD. No other apparent origins such as angioedema or late-phase allergic reaction to drugs were identified. One should be aware of the increased risk of developing airway and...

Recently, surface electrical stimulation applied to the neck region has received increased attention as a new modality to treat pharyngeal dysphagia. Previous reports used pulsed current at a frequency range of 1-120 Hz. Kilohertz-frequency alternating currents (ACs) have not been tested for treating dysphagia. Therefore, we evaluated the effects of interferential currents (IFCs), the most popular modality of amplitude-modulated kilohertz-frequency ACs in clinical practice, on the swallowing reflex in healthy subjects. We found that IFC stimulation at the sensory threshold with 50-Hz modulation significantly increased the number of swallows without any discomfort, but pure AC stimulation at the ca...

The goal of diet modification is to decrease the risk of patients aspirating food due to their diminished swallowing reflex. Some patients may not accept diet modification or may not adhere to the treatments identified by the interdisciplinary team. Such scenarios may result in important moral uncertainty and concern for clinicians. As a result of several ethics consultations related to this issue, a working group of the Clinical Ethics Committee at the Jewish Rehabilitation Hospital in Laval, Quebec, Canada, developed a framework for responding to situations when patients do not adhere to recommended diet modification. The goal of this tool is to facilitate di...

Twelve Caucasian adult subjects between 19 and 27 years of age participated. Subjects were recorded swallowing 7 cc of liquid barium in the upright and supine positions. The hyoid bone had a significantly greater amount of anterior displacement while in the supine position compared to that of the upright position (p < 0.01). While in the upright position, the velum comes to a fully elevated position at nearly the same time as the initiation of the pharyngeal swallow (within an average of 27 ms of each other), where...

The definite cause of this symptom is seldom precisely diagnosed, leading to chronic pharyngitis. The purpose of the present study was to evaluate the relationship between lump in throat and cervical degenerative disease by their clinical symptoms and the associated image characteristics. All patients with or without the complaint of lump in throat who attended the otolaryngologic clinics of Chang Gung Memorial Hospital—Kaohsiung Medical Center from January 2009 to May 2010 were prospectively eligible for this study. A total of 225 patients who met the inclusion criteria were assigned to either the study group (150 patients with symptoms of lump in the throat) or the control...

Contemporary perception theories suggest that the methods used in VFS reliability studies constrain subjects to make judgments in an abnormal way. The purpose of this study was to determine whether a directed search or a free search approach to rating swallow studies results in better interjudge reliability. Ten speech pathologists served as judges. Five clinical judges were assigned to the directed search group (use checklist) and five to the free search group (unguided observations). Clinical judges interpreted 20 VFS examinations of swallowing. Interjudge reliability of ratings of dysphagia severity, affected stage of swallow, dysp...

Because no epiglottic function assessment was performed preoperatively, for the purpose of this study it was assumed that epiglottic mobility was “normal” during this time and that all abnormalities found afterward resulted from the growth of the neoplasm and the glossectomy. It was noted that in the early postoperative period, absence of epiglottic movement was accompanied by aspiration and made swallowing incompetent in a majority of cases (9 of 10). A correlation of movement between the epiglottis and the extent of oral tissue excision was found. Epiglottic mobility was evaluat...

We found a high self-report of incidence of dysphagia and demonstrated that symptoms described by the patients follow a characteristic pattern. We conclude that there is a high incidence of dysphagia in all three of the inflammatory myopathies. Questions about swallowing should routinely be included in inflammatory myopathy patient examinations in order to appropriately refer patients for further investigation of their swallowing function and avoid the complications associated with dysphagia.

These thickeners are composed of primarily modified maize starch; some varieties also incorporate powdered gums. Amylase is a digestive enzyme found in saliva that initiates the breakdown of starch. To determine the significance of this process in dysphagia management, we measured the effects of human saliva on the viscosity of thickened drinks. Two thickeners were studied: one comprising modified maize starch alone and one that included additional gums. These were added to drinks with neutral and acidic pH: water and orange juice. Two clinical scenarios were simulated: (1) the effect of saliva on fluid as it is swallowed and (2) the effect when saliva enters a cup an...

Healthy adult men (N = 88) and women (N = 83) participated in the study. Strength measures were obtained using the Iowa Oral Performance Instrument (IOPI). Anterior and posterior tongue elevation strength measures were obtained using a standard method. Tongue protrusion and lateralization, cheek compression, and lip compression measures utilized adaptors allowing the participant to exert pressure against the bulb in different orientations. Lip and cheek strength measures were greater for men than women, but tongue strength did not differ between sex groups. Strong correlations between age and strength were not observed. However, group comparisons revealed lower tongue protrusion and lateral...

Swallowing, nutrition, and patient-perceived function for altered fractionation radiotherapy with concomitant boost (AFRT-CB) for T1–T3 oropharyngeal squamous cell carcinoma (SCC) have not been previously reported. Fourteen consecutive patients treated with AFRT-CB for oropharyngeal SCC were recruited from November 2006 to August 2009 in a tertiary hospital in Brisbane, Australia.

Swallowing function was studied in a cohort of 47 patients with locoregionally advanced (T1–4, N0–3) HNSCC treated with definitive CRT. Objective assessment of swallowing function was done using modified barium swallow (MBS) at baseline (pre-CRT) and subsequent follow-ups. Scoring of MBS was done using penetration–aspiration scale (PAS). Abnormal swallowing was defined in terms of incidence and severity of penetration–aspiration, pharyngeal residue, postural change, and regurgitation. Aspiration, residual, postural change, and regurgitation were present on ...

Sixteen months earlier the patient experienced a sudden severe fever which resulted in encephalitis, leading to liquid dysphagia. Despite receiving an initial treatment of swallowing therapy, the patient’s liquid dysphagia did not improve. Functional neuromuscular electrical stimulation, which is a new treatment method, was then applied to the patient. The patient showed improvement in the pharyngeal phase of swallowing. Clinical and treatment observations are reported.

Seventy patients with dysphagia underwent videofluoroscopic swallow studies (VFSS) between May 1, 2009 and September 30, 2009. Based on the findings of the VFSS, patients were divided into three groups: a thick-fluid aspiration group, a thin-fluid aspiration group, and a no-aspiration group. Kinematic analyses were performed during thick-fluid swallowing. Among our 70 patients, 23 had thick-fluid aspiration, 20 had thin-fluid aspiration, and 27 had no aspiration. A shortened duration of upper esophageal sphincter (UES) opening, a shorter interval between UES opening and peak pharyngeal constriction, and a diminish...

Automated extraction was compared to manual extraction for a subset of seven normal and the three disordered subjects to evaluate algorithm accuracy. Area and line integrals, pressure wave velocity, and pressure gradients during upper esophageal sphincter opening were also measured.

However, the research is incomplete regarding cervical auscultation and swallowing acoustics in that the differences between the sounds of normal versus dysphagic swallowing have yet to be fully understood or quantified. The swallows of 96 reportedly healthy adults, balanced for gender and divided into younger, middle, and older age groups, were audio-recorded while ingesting several boluses of varying viscosity and volume. The audio signals were then analyzed to determine their temporal and acoustic characteristics. Results indicated increasing pharyngeal swallowing ...

The condition results from abnormalities of esophageal motility. Our hypothesis is that there are also alterations of oral and pharyngeal transit during swallowing. We studied by videofluoroscopy the oral and pharyngeal transit during swallowing in 17 patients with dysphagia, a positive serologic test for Chagas’ disease, and radiologic demonstration of esophageal involvement. The study also included 15 asymptomatic healthy volunteers. Each subject swallowed in duplicate 5 and 10 ml of liquid and paste barium boluses. Chagas’ disease patients had a longer oropharyngeal transit with the 5-ml liquid bolus (p = 0.03), and a longer oral transit (p = ...

Variance was larger across sessions than within sessions for sensors 1 and 2 but comparable for sensor 3. For all sensors there was a high correlation between the variance across sessions and within session (r = 0.92, p < 0.0001). There were no significant order effects of session or of trial at any sensor with estimated order effects less than 2% and the estimated maximum possible change no large...

From the clinical point of view, voluntary swallow (VS) occurs when a human has a desire to eat or drink during the awake and aware state. Spontaneous swallow (SS) is the result of accumulated saliva and/or food remnants in the mouth. It occurs without awareness while awake and also during sleep. VS is a part of eating behavior, while SS is a type of protective reflex action. In VS, there is harmonized and orderly activation of perioral, lingual, and submental striated muscles in the oral phase. In SS, the oral phase is bypassed in most cases, although there may be partial excitation. Following the oral phase, both VS and SS have ...

We studied a prevalent population of PD cases. All of those who consented to participate were assessed for anxiety, depression, cognitive function, and quality of life using standard rating scales. Anyone who answered “yes” to either one of the two questions: Do you have difficulty swallowing food/liquid or tablets? and Do you cough after eating/drinking? was considered to have dysphagia. Question 7 of the Unified Parkinson’s Disease Rating Scale (UPDRS) was also used to identify dysphagia. Of 106 prevalent PD cases, 75 (38 males) patients consented to examination and assessment. The prevalence of dysphagia was 32.0% (n =&n...

The use of simulation has the potential to allow students to gain transnasal endoscopy experience with repetitive practice without compromising patients. The present study examined the effects of two different forms of simulation training on multiple transnasal endoscopic passes on healthy volunteers by graduate student clinicians as measured by procedure duration and confidence ratings. Eighteen speech-language pathology graduate student clinicians were randomly assigned to groups that utilized either a human patient simulator (HPS) or a non-lifelike...

The temporal measures stage transition duration (STD) and laryngeal closure duration (LCD) represent these physiological events. The purpose of this investigation was to determine whether small changes in bolus consistency and volume affect these temporal measures in poststroke patients who aspirate, poststroke patients who do not aspirate, and nonneurologically impaired control subjects. STD and LCD were obtained by frame-by-frame analysis of the videofluoroscopic examinations of 5 and 10 ml thin and nectar thick liquids. Using a three-way analysis of variance, STD was significantly different between the control group and the two po...

This cross-sectional study uses a cadaver model to document the structural properties of the muscles underlying these movements in an effort to understand how their morphology influences function. Measurements to determine physiological cross-sectional areas (PCSAs) of swallowing muscles were taken from hemisected head and neck formalin-fixed cadaver specimens (n = 13). Coordinates of muscle attachment sites and PCSAs were used to calculate ^ i   and ^ j   unit force vectors, where ^ i   and ^ j   represent anterior-posterior and superior-inferior directions, respectively. The suprahyoid muscle subsamples were grouped for an...

A swallow screen that maintains high sensitivity to identify aspiration risk while simultaneously reducing the false-negative rate for silent aspiration would be beneficial. The purpose of this study was to investigate whether silent aspiration risk was volume-dependent by using a 3-oz. (90-cc) water swallow challenge to elicit a reflexive cough when silent aspiration occurred on smaller bolus volumes. A prospective, consecutive, referral-based sample of 4102 inpatients from the acute-care set...

Motor-evoked potentials (MEPs), elicited by transcranial magnetic stimulation (TMS), were assessed in ten healthy volunteers prior to and at 5, 30, 60, and 90 min after 60 volitional saliva swallows (Protocol A). To control for intrinsic fluctuations in corticobulbar excitability during this assessment period, MEPs were also recorded, on a different day, at 30-min intervals across a 2-h period (Protocol B). At each assessment, 15 MEPs were recorded during two submental muscle preactivation conditions: volitional contraction and contraction associated with the ...

Subjects filled out a perception of swallow function form. Measures of stimulated salivary flow rate were also taken, and videofluoroscopic evaluation of swallowing was completed. The amount of saliva produced by patients with SS was significantly less than that produced by normal age-matched controls, and these patients perceived their swallowing to be impaired. Few statistically significant differences were found between the SS group and normal age-matched controls on temporal measures of swallowing, and 96% of swallows in the SS group were judged to be functional. There was no correlation between perception of swallowing and amount of saliva produced. No strong...

Anterior and superior displacement measures of both structures from previously published studies were compiled for meta-analysis. Results showed a large degree of variability across studies for each structure and plane of movement. Potential sources of variation were identified, including statistical, methodological, stimulus-related, and participant-related sources.

The event-related evoked potential provides a measure of neuronal electrical activity as it relates to a specific stimulus. Air-puff stimulation to the posterior pharyngeal wall produces a sensory-evoked potential (PSEP) waveform. The goal of this study was to characterize the scalp topography and morphology for the component peaks of the PSEP waveform. Twenty-five healthy men and women served as research participants. PSEPs were measured via a 32-electrode cap (10–20 system) connected to SynAmps2 Neuroscan EEG System. Air puffs were delivered directly to the oropharynx using a thin polyethylene tube connected to a flexible laryngoscope. The PSEP wav...

The motor disturbances are both choreiform and hypokinetic. As a result of the combination of these signs, it is known that many patients with HD suffer from dysphagia. Little is known about the frequency and the characteristics of dysphagia in HD. Well-balanced strategies for treatment and prevention of dysphagia in HD are lacking. Therefore, we have performed a detailed survey of the literature. We found that the patient groups studied were heterogeneous and the methods used were highly variable, and no balanced advice for prevention and treatment was systematically proven.

In this review we identify what is known regarding the sensory pathways and mechanisms that are now thought to influence swallowing motor control and evoke its response. By synthesizing the current state of research evidence and knowledge, we identify continuing gaps in our knowledge of these mechanisms and pose questions for future research.

Eleven healthy volunteers (7 men, 4 women; age range = 26–59 years) participated in the experiments. Tongue pressure during dry and 5- and 15-ml water swallows in neutral and chin-down postures was measured using a sensor sheet system with five measuring points on the hard palate. Sequential order, maximal magnitude, duration, and integrated value of tongue pressure at each measuring point were compared between postures and bolus sizes. Onset of tongue pressure at posterior-circumferential parts occurred earlier in dry swallow than in 5- and 15-ml water swallows in each posture. Chin-down posture was most effective f...

While 14 healthy volunteers aged 19–32 years old swallowed 5 ml of white soft yogurt in one gulp without chewing, the movement of the arytenoid regions was observed for videoendoscopic evaluation of swallowing (VE). Each moving image was stored simultaneously on videotape. A cross-sectional area surrounded by the epiglottis and the bilateral arytenoid regions (S) and the length of a straight line passing through the anterior borders of the left and right arytenoid regions (L) were measured. The relative area of the entrance in the laryngeal vestibule was calculated as [S/L 2] before the swallowing ref...

Forty-nine patients with advanced oral cavity, oropharynx, hypopharynx and larynx, or nasopharynx cancer treated with CCRT were randomized into a standard (S) or an experimental (E) preventive rehabilitation arm. Structured multidimensional assessment (i.e., videofluoroscopy, mouth-opening measurement, structured questionnaires) was performed before and 10 weeks after CCRT. In both S and E arms, feasibility was good (all patients could execute the exercises within a week) and compliance was satisfactory (mean days practiced per week was 4). Nevertheless, mouth opening, oral intake, and weight decreased signi...

In addition, this study sought to define associations between respiratory events, swallowing apnea duration, and penetration–aspiration (P–A) scale scores. Thirty-nine individuals with PD were administered ten trials of a 5-ml thin liquid bolus. P–A scale score quantified the presence of penetration and aspiration during the swallowing of a 3-oz sequential bolus. Participants were divided into two groups based on swallowing safety judged during the 3-oz sequential swallowing: Group 1 = P–A ≤ 2; Group 2 = P–A ≥ 3. Swallows were examined using videofluorosc...

Given that the pharyngeal phase of swallowing is a key component of the safe swallow, it was hypothesized that healthy older adults who aspirate are likely to generate less pharyngeal peak pressures when swallowing. Accordingly, pharyngeal and upper esophageal sphincter pressures were examined as a function of aspiration status (i.e., nonaspirator vs. aspirator), sensor location (upper vs. lower pharynx), liquid type (i.e., water vs. milk), and volume (i.e., 5 vs. 10 ml) in healthy older adults. Manometric measurements were acquired with a 2.1-mm catheter during flexible endoscopic evaluation. Participants (N = 19, mean age = 79.2 years) contributed 28 swallows; during 8 swal...

We performed a retrospective analysis of the medical records of eight patients who had LTS reversal. The operation was successful in six patients who were followed up for a period of 17-99 months (mean = 46.3 ± 26.2). The mean interval between LTS and surgical reversal was 16.6 ± 9.1 months. Four patients had postoperative complications: mild to moderate transient aspiration in two, tracheal stenosis in one, and severe aspiration followed by tracheal stenosis in one. In the last two cases, surgical reversal was not s...

Knowledge of range and variation of normative temporal measures could define abnormal deglutition and assist in design of appropriate compensatory and rehabilitative treatment techniques. The purpose of this retrospective study was to determine temporal measurements for oral filling, oral transit, onset of laryngeal closure, time of bolus arrival at the valleculae, pharyngeal delay, pharyngeal transit, and UES opening. Videofluoroscopic swallow studies of 15 normally swallowing pediatric subjects were divided into three age groups and method of liquid delivery. Mean, standard deviation, percentages, and extension of the median were utilized to determine relationships of temporal...

Voice samples were collected using a high-quality microphone from 40 adults during videofluoroscopy (VFSS), at baseline and following each of four thin liquid swallows. Blinded speech-language pathologists (SLPs) rated the audio recordings for voice quality using the GRBAS scale and the VFSS recordings for abnormal swallow onset, penetration-aspiration, airway closure, and pharyngeal residues. Acoustic measures of % jitter, % shimmer, and signal-to-noise ratio were calculated using two /a/ vowel segments spliced from each voice recording. Preswallow to postswallow measures of voice-quality change were derived and the data were...

A recent innovation has led to the replacement of the intraluminal probe by a wireless capsule. This capsule is attached to the esophageal wall and transmits the appropriate data to a patient-worn receiver. After a short period of time the capsule detaches itself from the wall and is eliminated. We recently encountered a patient in which the capsule did not detach in a timely manner. It was imaged during a preoperative esophagogram. Content Type Journal ArticleCategory Case ReportDOI 10.1007/s00455-010-9281-5Authors Bruce R.

The primary tumor was an extended papillary thyroid carcinoma (pT4N0M0). For vocal restoration, an indwelling Provox® 1 voice prosthesis was inserted secondarily. The patient received speech and swallowing therapy, including digital maneuvers at the level of the proximal (cervical) part of the jejunal graft to improve speech and swallowing function. Pre- and/ or post-treatment data on speech and swallowing function were gathered using the following assessment methods: esophageal insufflation test, Voice Handicap Index (VHI), videofluoroscopy of phonation (VFSph), d...

Despite its rarity, radiologists should be aware of this finding as a potential cause of dysphagia after radiation therapy to the neck or chest. Unlike radiation strictures, radiation-induced sacculation of the esophagus probably can be managed conservatively without need for endoscopic dilatation procedures.

Carotid artery dissection (CAD) is most common in middle-aged women. Although not completely known, the main risk factors related to carotid artery dissection are genetic and environmental factors, traumatic events, cervical manipulation, migraine, recent infections, hyperhomocysteinemia, and hereditary connective tissue disorders. Although some cases of bilateral internal CAD have been reported, spontaneous bilateral dissections are rare. Prolonged hoarseness is usually due to using the voice either too much, too loudly, or improperly over an extended period of time. D...

In this retrospective study, we investigated the outcome of FDT with or without PEG feeding. Patients with dysphagia were divided into two groups: those with PEG feeding (N = 117) and those with exclusively oral feeding (N = 105). Both groups received functional training (oral motor skills/sensation, compensatory swallowing techniques) from speech-language therapists. Functional oral intake, weight, Barthel index, and speech and language abilities were evaluated pre- and post-training. The non-PEG group showed a significant post-treatment improvement in functiona...

The vast majority of patients with cervical osteophytes are asymptomatic. However, in a small subset this condition may lead to upper aerodigestive compromise manifesting as dysphagia and/or airway obstruction. Conservative medical therapy is usually sufficient, but patients with intractable disease may require surgical intervention, including tracheostomy, feeding tube placement, or osteophytectomy. A retrospective chart review was performed on all patients who presented to a tertiary referral center over a decade (1998-2008) with complaints of dysphagia and/or respiratory co...

Barium esophagography revealed erosion of the cervical plate through the posterior wall of the pharyngoesophageal junction with an extraluminal collection that extended inferiorly as a track through the posterior wall of the trachea, producing a pharyngotracheal fistula. The pharyngeal perforation was repaired and the cervical hardware removed at surgery.

Three-dimensional (3D) images reconstructed from the thin axial slices include multiplanar reconstruction and 3D-CT. Single-phase 3D images are reconstructed from 0.175-s data, and multiphase 3D images are created in 29 phases at intervals of 0.1 s. Continuous replay of these 3D images produces four-dimensional moving images. In order to determine the feasibility of the morphologic and kinematic analyses of swallowing using 320-MSCT, single-phase volume scanning was performed on three patients and multiphase volume scanning was performed on one healthy vol...

Restriction of jaw movement, neck stiffness, absence of oral food intake, and weakness of the oropharyngeal and laryngeal muscles were considered to be the main factors contributing to the deterioration of his swallowing function. Treatment comprised exercises to improve flexibility of the neck and temporomandibular joint, tactile oral stimulation, passive and active oropharyngolaryngeal exercises, and supraglottic swallowing maneuvers. Treatment was performed for 30 min per day, three times a week, for 7 months. On initial videofluoroscopic examination, the patient was unable to safely tolerate any per-oral nutri...

Starch-based thickening agents are often employed; however, these exhibit great variation in consistency. The aim of this study was to compare viscosity and the rheological profile parameters complex (G*), viscous (G″), and elastic modulus (G′) over a range of physiological shear rates. UK commercially available dysphagia products at “custard” consistency were examined. Commercially available starch-based dysphagia products were prepared according to manufacturers’ instructions; the viscosity and rheological parameters were tested on a CVOR Rheometer. At a measured shear rate of 50 s−1, all products fell within the viscosity limits defined ...

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 responses. The MDQ-30, a 28-item instrument, took 10 min (range = 5–30 min) to complete. Four hundred thirty-one outpatients [210 (49%) men; mean age&...

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/or laryngeal aspiration diagnosed by videofluoroscopy. Submental electrical stimulations were performed for 1 h every day for 5 days (electrical trains: 5&nbs...

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 correlations with manual analysis and can account for head position changes during the study. While the hyoid bone was reported on in this study, other regions of inter...

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 be available or possible.

Thirty-three head and neck cancer patients (middle-aged women and men, and older women and men) were evaluated with videofluoroscopy before and 3 months after their cancer treatment. At 3 months post-treatment, the mean duration of laryngeal closure was longer for women than for men at 1-, 5-, and 10-ml bolus volumes. The duration of laryngeal closure at 3 months post-treatment and the duration of cricopharyngeal opening at both pretreatment and 3 months post-treatment increased as liquid bol...

To the best of our knowledge this is the first case report showing evidence of severe neurogenic dysphagia, possibly secondary to vagal nerve praxia, in a patient who underwent posterior fusion. A 61-year-old man presented with severe neck pain after he sustained a fall. Imaging studies in the emergency department showed a C2 fracture associated with anterior subluxation of C2 on C3. Given the instability of the injury, a C1–C3 posterior cervical fusion was performed. The surgery was uneventful. The patient’s postoperative course was complicated by severe dysphagia.

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 children with Pompe disease using videofluoroscopy before initiation of ERT, allowing for baseline swallow function to be established in an untreated cohort.

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 or marked improvement of dysphagia and aspiration and as failure in the case of partial improvement or no improvement. Initial results showed success in 21 and failure...

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 were analyzed for both 5-ml and 10-ml thin-liquid boluses using a 100-ms timer during subsequent analysis of videofluoroscopic swallowing examinations.

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.
