Chewing Well Modulates Pharyngeal Bolus Transit During Swallowing in Healthy Participants
AbstractMastication is controlled by central pattern generator in the brainstem and can be modulated by volition. The aim of this study was to investigate the effect of chewing well on swallowing. Twenty-six healthy participants were instructed to eat 8, 12, and/or 16 g of steamed rice with barium sulphate under the following two conditions: chewing freely task (CF; chewing naturally in their usual manner) and chewing well task (CW; chewing the food with a request to “chew well”). We evaluated bolus transport and swallowing movement using videofluoroscopy a nd electromyography of the masseter, suprahyoid and thyrohyo...

Global State of the Art and Science of Childhood Dysphagia: Similarities and Disparities in Burden
This article reviews current global population and resource-dependent influences on current trends for children with dysphagia, disparities in the availability and access to specialized multidisciplinary care, and potential impacts on burdens. A patient example will illustrate some questions to be considered and decision-making options in relation to age and development, availability and accessibility to resources, as well as diverse cultures and family values. Precise recognition of feeding/swallowing disorders and follow-up intervention are enhanced by awareness and knowledge of global disparities in resources. Initiativ...

Dysphagia and Functional Limitations Among Adults in the United States: Findings from the 2022 National Health Interview Survey
This study aimed to determine if individuals with dysphagia had difficulties with participating in daily tasks requiring physical function, as compared to those with no dysphagia. We conducted a secondary data analysis using the responses of 24,107 adults aged 18 years or older who completed the 2022 National Health Interview Survey. The independent variable was report of swallowing problem during the past 12 months, and the dependent variables were report of difficulty in physical function tasks (e.g., self-care, mobility, working, social participation). We utilized propensity score methods to balance demographic and c...

People with Intellectual Disabilities, Dysphagia and Post-Covid Syndrome
AbstractPeople with Intellectual Disability (ID) were more likely to contract COVID-19 infection and more likely to die from the consequences. However, there is no evidence on the long-term impact of COVID-19 infection in people with ID. Post-Covid Syndrome (PCS) is an established diagnosis that requires specialist clinical support. To date there is no data on how common PCS is in people with ID, or how symptoms present. Dysphagia is identified as a clinical marker because of the known association with PCS, and the clear objective diagnostic criteria applicable through specialist assessment. This investigation presents a c...

Mechanisms of Swallowing, Speech and Voice Disorders in Parkinson ’s Disease: Literature Review with Our First Evidence for the Periperal Nervous System Involvement
AbstractThe majority of patients with Parkinson ’s disease (PD) develop swallowing, speech, and voice (SSV) disorders. Importantly, swallowing difficulty or dysphagia and related aspiration are life-threatening conditions for PD patients. Although PD treatments have significant therapeutic effects on limb motor function, their effects on SSV di sorders are less impressive. A large gap in our knowledge is that the mechanisms of SSV disorders in PD are poorly understood. PD was long considered to be a central nervous system disorder caused by the death of dopaminergic neurons in the basal ganglia. Aggregates of phosphoryla...

Speech-Swallow Dissociation of Velopharyngeal Incompetence with Pseudobulbar Palsy: Evaluation by High-Resolution Manometry
AbstractPatients with pseudobulbar palsy often present with velopharyngeal incompetence. Velopharyngeal incompetence is usually observed during expiratory activities such as speech and/or blowing during laryngoscopy. These patients typically exhibit good velopharyngeal closure during swallowing, which is dissociated from expiratory activities. We named this phenomenon “speech-swallow dissociation” (SSD). SSD on endoscopic findings can help in diagnosing the underlying disease causing dysphagia. This endoscopic finding is qualitative, and the quantitative characteristics of SSD are still unclear. Accordingly, the curren...

Relationship Between Submental Superficial Layer Hardness and Tongue Pressure Determined Using a Tissue Durometer
AbstractAging affects the tongue and suprahyoid muscles, causing dysphagia and undernutrition. We hypothesized that tongue function would affect submental superficial layer hardness. Tongue movements during water retention between the tongue and palate are the same as those required during bolus formation, involving internal and external tongue muscle movement. In 28 healthy adults (14 males, 14 females, average age 28.7 ± 2.9 years), we measured the submental superficial layer characteristics (frequency [tension], stiffness, decrement [inverse of resilience], relaxation, and creep [deformation over time]) using a si...

Changes in the Activation Level of the Floor of the Mouth Muscles during Pressing and Swallowing Tasks According to the Degree of Tongue Pressure
This study attempted to confirm whether systematic resistance can be provided to the suprahyoid muscles using the Iowa Oral Performance Instrument (IOPI) —a representative tongue pressure measurement device. Thirty-one healthy adults participated in this study (20.6 ± 0.96 y, 19 females). The participants performed 16 exercise tasks using the IOPI three times each in random order (Anterior/posterior tongue × pressing/swallowing task × 40/60/ 80/100% maximum tongue pressure). Furthermore, the floor of the mouth (FOM) muscle activity during exercise was simultaneously measured using surface electromyography. During ...

Risk Factors Associated with Unsuccessful High-Resolution Manometry
AbstractHigh-resolution manometry (HRM) is used to evaluate the esophageal motor function. Unfortunately, there are times when testing cannot be performed accurately. Our study aimed to quantify the occurrence of failed HRM and identify the associated risk factors. HRM tests were retrospectively collected between September 2021 and August 2022. HRM reports that could not be interpreted based on standard HRM protocol as per Chicago guidelines were classified as failed tests. Information reviewed included testing indications, patient demographics, previous med ical/symptom history, and follow-up testing for failed HRM. We ...

Prevalence of Dysphagia and Risk of Malnutrition in Elderly Living in Nursing Homes
AbstractSwallowing difficulties commonly co-occur with malnutrition in the elderly. However, there is no consensus on which assessment tools to use, and thus reported prevalence varies. The aim of this study was to survey the prevalence of dysphagia and risk of malnutrition in elderly people in nursing homes, evaluate the possible associations between swallowing function and malnutrition and survey whether there were associations between self-perceived function and the results of a screening of dysphagia. A total of 35 residents (aged 67 –100 years old) without serious cognitive impairment in the general wards of two nu...

Hyoid Bone Movement During Swallowing in Female Thyroidectomy Patients: A Kinematic Ultrasound Study
AbstractThe aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis inclu...

Dysphagia in Open Partial Horizontal Laryngectomy Type IIa: Quantitative Analysis of Videofluoroscopy using the ASPEKT Method
AbstractOpen Partial Horizontal Laryngectomy (OPHL) Type IIa surgery is a conservative surgical technique used in the treatment of laryngeal carcinomas. In this pilot study, we aimed to characterize swallowing function and physiology in a series of patients after OPHL Type IIa surgery through comparison to healthy reference values for quantitative measures for videofluoroscopy. We performed retrospective quantitative analysis of videofluoroscopy recordings of thin liquid swallows for a preliminary sample of 10 male patients. Each videofluoroscopy clip was rated in triplicate by trained blinded raters according to the ASPEK...
