Abstract
Even without diseases that cause dysphagia, physiological swallowing function declines with age, increasing the risk of aspiration. This study analyzed age-related changes in laryngeal movement in older adults. The study population consisted of 10 volunteers in their 80s and six in their 20s. A videofluoroscopic study of 3 and 10 mL barium swallows was performed laterally using a digital fluorographic. The recorded images were retrieved to a personal computer and analyzed frame-by-frame using video analysis software. The movement of the larynx during swallowing, barium's pharyngeal transit time (PTT), and laryngeal elevation delay time (LEDT) were analyzed. Results were compared between the 20s and 80s age groups using statistical analyses. The PTT was shorter in the 20s than in the 80s age group. The PTT was significantly longer in the 80s group than in the 20s for both 3 and 10 mL barium swallows. LEDT in the 80s was statistically significantly longer than that in the 20s for the 10 ml barium. No statistically significant differences were found; however, there was a tendency for the 80s group to have more types of laryngeal movement velocity peaks. In this study, LEDT was prolonged in the 80s with 10 ml barium swallowing than in the 20s. Two peak patterns of laryngeal elevation during swallowing were observed. The velocity peaks showed a two-peak pattern when the patients were in their 80s and when the barium volume was tested at 10 mL. Our results suggest that aging's effect on swallowing relates to laryngeal elevation.

JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2023; 66:820-831. [PMID: 36720117 PMCID: PMC10205106 DOI: 10.1044/2022_jslhr-22-00413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 10/06/2022] [Accepted: 11/10/2022] [Indexed: 05/25/2023]
Abstract
PURPOSE We quantified pharyngeal residue using pixel-based methods in a normative data set, while examining influences of age, gender, and swallow task. METHOD One hundred ninety-five healthy participants underwent a videofluoroscopic swallow study following the Modified Barium Swallow Impairment Profile (MBSImP) protocol. ImageJ was used to compute Normalized Residue Ratio Scale and the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) pharyngeal residue measures. Reliability was established. Descriptive statistics were performed for all residue measures. Inferential statistics were performed using ASPEKT total scores (i.e., %C2-42). Logistic regression models explored predictors of residue versus no residue. Generalized linear mixed models explored predictors of nonzero residue. Spearman rho explored relationships between ASPEKT total residue scores and MBSImP Component 16 (Pharyngeal Residue) scores. RESULTS Majority of swallows (1,165/1,528; 76.2%) had residue scores of zero. Residue presence (%C2-42 > 0) was influenced by age (more in older [F = 9.908, p = .002]), gender (more in males [F = 18.70, p < .001]), viscosity (more in pudding, nectar, and honey [F = 25.30, p < .001]), and volume (more for cup sip [F = 37.430, p < .001]). When residue was present (363/1,528 = 23.8%), amounts were low (M = 1% of C2-42, SD = 2.4), and only increasing age was associated with increased residue (F = 9.008, p = .007) when controlling for gender and swallow task. Increasing residue was incremental (0.01% of C2-42 per year). As ASPEKT total residue values increased, MBSImP Component 16 scores also increased. CONCLUSIONS Pharyngeal residue amounts were very low in healthy adults. Residue presence can be influenced by age, gender, and swallow task. However, when present, the amount of pharyngeal residue was only associated with increasing age. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.21957221.

Abstract
BACKGROUND Sensation and perception impairments are significant problems faced by individuals with early-stage stroke. Sensory inputs needed in swallowing guide the perceptual process with the involvement of cognitive functions. In the absence of sensory input, bolus perception may be altered, and swallowing safety may be compromised. OBJECTIVES This study aims to evaluate the oral perception of volume change and the aspiration risk of individuals with stroke and determine the relationship between oral perception and aspiration risk. METHODS Total participants were 35. The Gugging Swallowing Screening Test (GUSS) was used to determine individuals' risk of aspiration and divide them into groups 'aspiration risk' and 'non-aspiration risk'. The Oral Perception of Liquid Volume Changes Test (OPLVCT) was used to determine the level of oral perception. RESULTS The groups were statistically similar in terms of age and other descriptives. When the OPLVC test was examined, the scores of the aspiration risk group were significantly lower (p < .001). In addition, a moderate negative correlation was found between aspiration risk and the OPLVC scores (r: -0.502; p < .001). CONCLUSION In this study, a relationship was found between aspiration risk and oral perception. It also revealed that individuals with stroke who are at risk of aspiration have low oral perception abilities. Based on these results, it was concluded that these individuals cannot reliably determine the maximum volume of liquid to be consumed without assistance. We suggest that evaluations and training of oral perception should be added to the rehabilitation of individuals with stroke.

Abstract
AIM Swallowing is a vital activity. The difficulty while swallowing, referred to as swallowing disorder, is strongly associated with serious health problems in the elderly. The aim of this study is to enable early recognition of the swallowing function developing as an asymptomatic condition. METHOD Our study was conducted on elderly populations aged 65 years and over who met the exclusion criteria. Firstly, to be able to reach the number of sampling, "EAT-10 questionnaire", which also has a Turkish validation, was used to eliminate those with symptomatic swallowing disorders. The number of patients we reached was 320, but 7 dropped out of the study and therefore the study was carried out with a total of 313 [reached as 97.8% (up 95% G-power)]. RESULT We used validated sEMG test in the quantitative (objective) detection of asymptomatic swallowing disorder. In this method, asymptomatic swallowing disorder was detected in 39 cases (12.4%). CONCLUSION Swallowing disorder without symptoms is frequent and the sEMG test is useful in detecting it in the elderly population.

Abstract
Age-related swallowing changes are well-researched in deglutology, usually distinguishing those over 60 years as older aged. World-wide, older adults are healthier and forecast to live longer: many over 85 years. It is necessary for clinicians to understand healthy swallowing changes in this 'oldest old' in order to appropriately manage swallowing complaints in older patients. This systematic review collated and critically appraised studies investigating swallowing changes in adults over 85 years using instrumental assessment. Criteria for inclusion were healthy subjects over 85 years. Exclusion criteria included studies focused on anatomy and oral processing. Studies published until December 2018 were retrieved from BIOSIS, CINAHL, Embase, Medline, and Scopus, totaling 2125 articles. During data screening, 64% of studies investigating age-related swallowing changes were excluded, as the oldest old were not recruited. After PRISMA screening, 44 articles met criteria. These were further reviewed for data extraction, bias and quality. Main quantitative age-related changes in swallowing included increases in delay in swallow onset, bolus transit times, duration of UES opening, pressure above the UES and UES relaxation pressure, and reduction in pressure at the UES. Few studies detected increased residue or airway compromise in the form of aspiration. Results were not easily comparable due to differences in age ranges, methods for deeming participants 'healthy', measures used to define swallowing physiology, and swallowing tasks. Age-related swallowing changes are identified that do not compromise safety. The oldest old are underrepresented in normative deglutition research. It is essential future studies plan accordingly to recruit those over 85 years.

Abstract
PURPOSE OF REVIEW To present current literature regarding swallowing function in advanced age, including healthy ageing, dysphagia and trends in multidisciplinary team service delivery. RECENT FINDINGS Normative studies support swallowing efficiency but greater variability in healthy advanced age, through to 100 years old. Deviations from normative data and symptoms of dysphagia leading to aspiration or nutritional risk, imply swallowing disorder, rather than simply the ageing process. Quantitative and qualitative studies are emerging that promote management of swallow dysfunction for an ageing society, including innovative assessment, home treatment, swallowing exercise and optimized mealtimes. SUMMARY Current literature on swallowing function in advanced age provides multidisciplinary perspectives and initiatives, with clear commitment to improving quality of life for older adults. The diversity of the older population and serious consequences of swallowing difficulties calls for routine screening tools for swallowing impairment and malnutrition risk. Representation of 'oldest old' in future normative studies is essential to guide swallowing management in adults over 85 years old.

Abstract
KEY POINTS To swallow food and liquid safely, airway protection is essential. Upward and forward movements of the hyoid and larynx in the neck during swallowing vary in magnitude between individuals. In healthy human adults, hyoid and laryngeal movements during swallowing were scaled by differences in initial upper airway area before swallowing. Individuals increased laryngeal elevation during swallowing in response to increased airway opening before swallowing. We show that when upper airway protection requirements change, individuals use an internal sensorimotor scaling system to adapt movements to maintain swallow safety. ABSTRACT Hyoid and laryngeal movements contribute to laryngeal vestibule closure and upper oesophageal 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. We hypothesized that healthy individuals adapt to their own anatomy by adjusting hyo-laryngeal movements to achieve closure of the upper airway. We also investigated if individuals would automatically compensate for changes in their initial hyo-laryngeal positions and area when head position was changed prior to swallowing. Videofluoroscopy was performed in 31 healthy adults. Using frame-by-frame motion analysis, anterior and superior hyoid and laryngeal displacement, and hyo-laryngeal area were measured prior to and during swallowing. Kinematic measurements during swallowing were examined for relationships with pharyngeal neck length, and initial hyo-laryngeal positions, length and area before swallowing. During swallowing, individuals altered laryngeal elevation magnitude to exceed hyoid elevation based on hyo-laryngeal length before swallowing. Anterior laryngeal displacement was related to initial larynx distance from the spine, while hyoid elevation was predicted by pharyngeal neck length and initial hyoid distance from the mandible prior to the swallow. In conclusion, individuals automatically adapt hyo-laryngeal movement during swallowing based on targets required for closing the hyo-laryngeal area for safe swallowing.

Abstract
Bolus volume has been widely studied, and research has demonstrated a variety of physiological impacts on swallowing and swallowing disorders. Oral perception of bolus volume has not, to our knowledge, been investigated in association with normal ageing processes. Research suggests many sensory changes with age, some within the oral cavity, and changes in swallowing function with age have been defined. The role of perception in oropharyngeal deglutition with age requires further investigation. The purpose of this study was to establish the psychophysical relationship between liquid volume and oral perception and examine changes with age. Healthy young and older adults were prospectively assessed using a magnitude estimation task differentiating five volumes of water delivered randomly to the oral cavity. Results suggest a fourfold increase in liquid volume is required by older participants to perceive an approximate twofold increase in the perception of volume compared with younger healthy adults. Sensory receptors in the oral cavity provide a feedback loop that modulates the swallowing motor response so that it is optimal for the size and consistency of the bolus. Changes in perception of bolus volume with age are consistent with other perceptual changes and may provide valuable information regarding sensorineural rehabilitation strategies in the future.

Abstract
PURPOSE Mealtime management in Residential aged care facilities (RACFs) should be holistic and comply with the principles of person-centred care (PCC) to ensure residents' medical, nutritional and psychosocial mealtime needs are met. However, this is not always achieved and multiple issues with mealtime management in RACFs exist. The aim of the current study was to compare documented, reported and observed mealtime management to explore factors influencing optimal mealtime care. METHOD Data were triangulated from: (a) review of 14 resident files; (b) observation of 41 mealtimes; (c) questionnaires with 14 residents; and (d) questionnaires with 29 staff. RESULT Results revealed multiple discrepancies between data sources leading to the delivery of sub-optimal mealtime care. Poor documentation impacted staff knowledge of required mealtime practices resulting in occasions of inconsistent and inappropriate care. Observational and interview data highlighted discrepancies between residents' mealtime preferences and actual practice. In many instances observed care was not holistic nor consistent with PCC. CONCLUSION Given the significant medical, nutritional and psychosocial risks associated with poor mealtime management, systematic changes in policy, staff training and multidisciplinary care are needed.

Abstract
Parkinson’s disease (PD) is a chronic, neurodegenerative movement disorder that typically affects elderly patients. Swallowing disorders are highly prevalent in PD and can have grave consequences, including pneumonia, malnutrition, dehydration and mortality. Neurogenic dysphagia in PD can manifest with both overt clinical symptoms or silent dysphagia. Regardless, early diagnosis and objective follow-up of dysphagia in PD is crucial for timely and appropriate care for these patients. In this review, we provide a comprehensive summary of the electrophysiological methods that can be used to objectively evaluate dysphagia in PD. We discuss the electrophysiological abnormalities that can be observed in PD, their clinical correlates and the pathophysiology underlying these findings.

Abstract
BACKGROUND & AIMS The presence of a nasogastric tube (NGT) affects swallowing physiology but not function in healthy young adults. The swallowing mechanism changes with increasing age, therefore the impact of a NGT on swallowing in elderly individuals is likely to be different but is not yet known. The aims of this study were to determine the effects of NGTs of different diameter on (1) airway penetration-aspiration, (2) pharyngeal residue, and (3) pharyngeal transit, in older healthy subjects. METHODS Randomized controlled crossover design. Healthy elderly volunteers underwent 3 modified barium swallow studies in which multiple diet and fluid consistencies were swallowed under the following conditions: (A) no NGT (control), (B) fine bore NGT, and (C) wide bore NGT. The control condition was assessed first to establish baseline swallowing function, then NGT order was randomly allocated. RESULTS Of the 15 volunteers (median age 65 years, range 60-81) complete data sets were obtained for 9 (4 with allocation order ABC; 5 with ACB). Wide bore NGT data could not be obtained for 6 volunteers mainly due to tube intolerance. The presence of a NGT was associated with: (i) an increase in airway penetration-aspiration (fine bore NGT with serial liquid swallows and puree) (p < 0.01); (ii) increased pharyngeal residue (p < 0.05) in the pyriform sinus (fine bore NGT with puree); and in the valleculae (both fine and wide bore NGT with soft solids); and (iii) an increase in pharyngeal transit duration regardless of consistency (p < 0.01), with longest swallowing durations with the widest tube. CONCLUSIONS NGT presence increases airway penetration-aspiration, pharyngeal residue and prolongs transit through the pharynx in older healthy individuals. Consideration of NGT impact on swallowing during concurrent oral and enteral feeding is recommended, with further systematic investigation required in elderly patients recovering from critical illness.

Abstract
PURPOSE This study examined the effects of chin-down swallowing on laryngeal vestibule closure. It also investigated the technique's rehabilitative impact, by assessing the stability of effects across multiple trials and aftereffects in neutral swallows on cessation of the technique. METHOD Duration of laryngeal vestibule closure (dLVC) was measured with videofluoroscopy in 16 healthy participants (mean = 33.2 years, 9 men). Participants swallowed 40 times: 5 head-neutral swallows (N1), then 30 chin-down swallows, followed by 5 head-neutral swallows (N2). The first 5 chin-down swallows were categorized as early posture swallows (P1) and the last 5 as late posture swallows (P2). Within-participant comparisons determined the effects of the maneuver on dLVC during and after execution. RESULTS The study found that dLVC increased during chin-down swallows (N1 to P1, p = .018). This increase remained stable throughout 30 repetitions (P1 to P2, p = .994). On return to neutral, dLVC returned to baseline (N1 to N2, p = .875). CONCLUSIONS This study demonstrated increased dLVC during chin-down swallowing, offering a possible mechanism responsible for previously reported reduced aspiration during the technique. As aftereffects were not evident after multiple chin-down swallows, the maneuver appears to offer more compensatory benefit than rehabilitative value for patients with dysphagia.

Abstract
OBJECTIVES We undertook to provide data regarding temporal measurements of swallow function obtained by dynamic magnetic resonance imaging in a midsagittal plane and to compare these values to normative fluoroscopy data. METHODS Seventeen healthy female volunteers with no swallowing complaints underwent turbo-fast low-angle-shot magnetic resonance imaging with a 3-T scanner while swallowing liquid and pudding boluses delivered via syringe. Ninety sequential images were acquired with a temporal resolution of 113 ms per frame for each swallow. The imaging was performed in the midsagittal plane. The analyses focused on oral and pharyngeal transit times. RESULTS All subjects tolerated the protocol without complaints or adverse events. The mean (+/- SD) oral transit times for liquids and pudding were measured as 0.25 +/- 0.09 second and 0.25 +/- 0.13 second, respectively. This difference was not statistically significant (p = 0.74). The mean pharyngeal transit times for liquids and pudding were measured as 0.84 +/- 0.16 second and 1.11 +/- 0.21 seconds, respectively. This difference achieved statistical significance (p < 0.0001). The intrarater and inter-rater reliabilities for the measurements were excellent. CONCLUSIONS This sequence provided a high degree of temporal resolution of deglutition in the midsagittal plane. Furthermore, the temporal measurements acquired with dynamic magnetic resonance imaging were reliable and were relatively consistent with those of previous studies done with videofluoroscopy.

Abstract
Meeting the medical, nutritional, and psychosocial mealtime needs of aged care residents requires a holistic, multidisciplinary approach. To date the perspectives of this multidisciplinary team have not been adequately explored. The aim of this study was to explore the perspectives of a range of service providers involved in mealtime management in residential aged care. In-depth semistructured interviews were conducted with 61 participants from five service disciplines. Four themes emerged: ( 1 ) mealtimes are highly valued; ( 2 ) service providers face common barriers to mealtime management; ( 3 ) communication among service providers is challenging; and ( 4 ) education in mealtime management is limited. Data indicated service providers acknowledge the importance of mealtimes but recognize numerous shortfalls in current care. The need for interdisciplinary training and increased communication and collaboration among providers was emphasized, including the need for clarification of provider roles. Limited consideration of mealtimes in policy and funding documents was identified as a primary barrier in further prioritizing mealtime management and advancing mealtime care.

Abstract
OBJECTIVES/HYPOTHESIS In previous studies, we consistently found that approximately 30% of asymptomatic healthy older adults silently aspirated liquids during a flexible endoscopic evaluation of swallowing (FEES) and that their aspiration status was stable for the following year. However, no studies have systematically evaluated effects of silent aspiration on lung parenchyma and airways. We used computed tomography (CT) to compare lungs of healthy older adult aspirators versus nonaspirators. We hypothesized that CT images would show pulmonary differences in healthy older adult aspirators versus nonaspirators. STUDY DESIGN Prospective study. METHODS Fifty healthy older adults (25 aspirators and 25 nonaspirators) who participated in a previous FEES were randomly selected. CT scans were performed; on inspiration, lung views were taken at 1.25 mm and 2.5 mm windows, and on expiration, lung views were taken at 2.5 mm. CT scans were reviewed by radiologists blinded to group assignment. Outcomes included bronchiectasis, bronchiolectasis, bronchial wall thickening, parenchymal band, fibrosis, air trapping, intraluminal airway debris, and tree-in-bud pattern. RESULTS χ(2) analyses between aspirators and nonaspirators found no statistically significant differences between aspirators and nonaspirators for any outcomes (P > .05). Logistic regression analyses adjusted for smoking did not change the results. CONCLUSIONS There were no differences in pulmonary CT findings between healthy older adult aspirators and nonaspirators. This study adds to the evidence that some aspiration may be within the range of normal for older adults, or at least does not contribute to a change in pulmonary appearance on CT images. LEVEL OF EVIDENCE 3b.

Abstract
OBJECTIVES In multiple separate studies, we consistently found that approximately 30% of asymptomatic healthy older adults silently aspirated liquids during flexible endoscopic evaluation of swallowing (FEES). We subsequently questioned whether aspiration status remained stable in healthy older adults over time. The purpose of this study was to determine the stability of aspiration status in healthy older adults over time. METHODS Eighteen healthy older participants, comprising of 9 aspirators and 9 nonaspirators whose aspiration status was identified in a previous study, underwent a second FEES approximately 6 to 21 months later. The participants contributed 36 swallows, comprising 5-, 10-, 15-, and 20-mL boluses of milk (ie, 1 bolus of each volume of skim, 2%, whole, and soy milk) and water via cup and straw delivery, during the original FEES. An abbreviated protocol was administered for the repeat FEES. The Penetration-Aspiration Scale was used to rate all swallows. RESULTS A McNemar test demonstrated no change in aspiration status among participants between the initial test and the retest (p > 0.999). CONCLUSIONS In this cohort, the aspiration status was stable over about 12 months. This finding lends credence to the premise that trace aspiration of liquids may be a normal and consistent finding in some healthy older adults.

Abstract
OBJETIVO: verificar se as condições referentes à estrutura geral dos asilos, recursos humanos e rotinas diárias de alimentação em instituições asilares, podem potencializar alterações da dinâmica da deglutição em idosos. MÉTODOS: foi aplicado questionário aos dirigentes de cinco instituições asilares do município do Rio de Janeiro, no qual constavam perguntas em relação aos recursos materiais, humanos e rotina alimentar. RESULTADOS: o asilo do sistema privado foi o único a aproximar-se das condições ideais da estrutura geral para o atendimento do idoso. Em relação aos recursos humanos existentes, nenhum dos asilos possuía todos os profissionais exigidos pela portaria nº810/89. Em relação às rotinas diárias de alimentação, em uma das instituições pesquisadas, cuja maioria dos residentes não faziam uso de próteses dentárias, não havia restrição na consistência alimentar oferecida. Outro fator significativo diz respeito à negligência referente à higiene bucal, favorecendo a colonização de bactérias na cavidade oral, podendo agravar infecções pulmonares no caso de microaspirações. O fato dos idosos deitarem para dormir logo após o término das refeições, como ocorrido em três das instituições pesquisadas, tem grande importância na medida em que favorece a ocorrência de episódios de refluxo gastroesofágico. CONCLUSÃO: foram observados que em todas as instituições pesquisadas há fatores que podem potencializar um distúrbio de deglutição, como problemas em relação à estrutura geral e ou aos recursos humanos e ou relativos à rotina alimentar estabelecida.

Abstract
Clinical swallow protocols cannot detect silent aspiration due to absence of overt behavioral signs, but screening with a much larger bolus volume, i.e., 90 cc vs. 1-10 cc, may elicit a reflexive cough in individuals who might otherwise exhibit silent aspiration. 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 setting of a large urban tertiary-care teaching hospital participated. Silent aspiration was determined first by fiberoptic endoscopy and then each participant was instructed to drink 3 oz. of water completely and without interruption. Criteria for challenge failure were inability to drink the entire amount, stopping and starting, or coughing and choking during or immediately after completion. Improved identification of aspiration risk status occurred for 58% of participants who exhibited silent aspiration on smaller volumes, i.e., an additional 48% of liquid silent aspirators and 65.6% of puree silent aspirators coughed when attempting the 3-oz. water swallow challenge. A low false-negative rate was observed for the entire population sample, i.e., ≤2.0%. A combined false-negative rate for participants who silently aspirated was 6.9%, i.e., 7.8% if silently aspirated liquid and 6.1% if silently aspirated puree consistency. Determination of silent aspiration risk was shown to be volume-dependent, with a larger volume eliciting a reflexive cough in individuals who previously silently aspirated on smaller volumes. A 3-oz. water swallow challenge's previously reported high sensitivity for identification of aspiration risk combined with the newly reported low false-negative rate mitigates the issue of silent aspiration risk during clinical swallow screening.

Abstract
OBJECTIVES To compare hyolaryngeal complex (HLC) movement and leading-edge-of-the-bolus location patterns of sequential swallowing in patients with stroke and healthy adults, and to determine whether these patterns affect swallowing safety. DESIGN Between-groups comparison. SETTING Veterans hospital. PARTICIPANTS Consecutively admitted patients with acute unilateral supratentorial stroke (right hemisphere damage, n=13; left hemisphere damage, n=16) and age-matched healthy participants (n=25). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES HLC movement pattern, bolus location, Penetration-Aspiration (P-A) Scale score. RESULTS No significant group differences were observed for HLC movement pattern, bolus location, and P-A Scale score. Specific HLC movement patterns and bolus location were not associated with a higher P-A Scale score. A significant correlation between HLC movement pattern and bolus location was observed. Bolus location was typically inferior to the valleculae between swallows when the HLC was partially elevated. Across all groups, P-A Scale scores were significantly higher during sequential swallowing than single swallows. CONCLUSIONS HLC movement pattern and bolus location do not appear related to airway invasion, at least in persons without significant dysphagia. Given higher P-A Scale scores during sequential swallowing as compared with single swallows, sequential swallowing should always be evaluated in all patients.

Abstract
Objective. To evaluate the effects of occlusion status (i.e., open, finger, capped) of the tracheotomy tube and removal of the tracheotomy tube that may have upon bolus flow and durational measurements in nondysphagic persons requiring a tracheotomy tube.
Study Design. Prospective, single subject, repeated measure design.
Methods. Participants had their swallow evaluated with 5 mL pureed boluses using nasal endoscopy with the tracheotomy tube in place, removed, and under the following occlusion conditions: open, finger, and capped. The order of occlusion condition was randomized.
Results. Aspiration was never observed but laryngeal penetration was a common finding. Durational measurements for swallow initiation and duration of white out were not significantly different by occlusion status or after removal of the tracheotomy tube.
Conclusion. This study provides corroborating evidence demonstrating the lack of a relationship between a tracheotomy tube and swallowing dysfunction.

Abstract
Vertical and anterior displacement of the hyoid bone is a critical biomechanical component of normal swallowing function. The purpose of this study was to evaluate the maximal vertical and anterior displacement of the hyoid bone during oropharyngeal swallowing. A retrospective review of video-fluoroscopic swallowing exams in 40 normal subjects varying by age and gender was performed. Means and standard deviations for both vertical and anterior displacement were analyzed on both 5-ml and 10-ml thin liquids using an ImageJ program. Age and gender differences were submitted to a repeated-measures one-way analysis of variance. There was a significant difference between younger and older subjects for anterior displacement of the hyoid bone during the swallow but not for vertical displacement. No significant differences between male and female subjects were observed. Anterior displacement of the hyoid bone decreased with increasing age. This reduction may be related to muscle weakness. However, older people may adapt to preserve airway protection.
