Producing tongue pressure (TP) by pushing the against palate consists of lifting muscles and elevating floor mouth via suprahyoid muscle contraction. Though studies have shown that tongue-pressure resistance training (TPRT) increases function, none focused on function enhancements. Our study aimed to verify whether TPRT improves both hyoid movement during swallowing.Eighteen patients (mean age: 76.8±6.2 years) with presbyphagia presenting symptoms such as coughing choking were enrolled. All...
Background/Objectives: The effects of ageing on the diaphragm are unclear. This study examined association between and thickness, thickening fraction (TF), excursion (DE) as assessed by ultrasonography after adjusting for other factors. relationship these parameters maximal inspiratory pressure (MIP) was also investigated. Methods: From 2022 to 2024, ambulatory communicative adult volunteers outpatients were recruited from four Japanese medical institutions. Each participant’s background...
Previous studies have reported a relationship between masseter muscle thickness and tooth loss or limb thickness. However, it is not yet known whether related to appendicular skeletal mass, grip strength. The purpose of this study was determine which the two variables-tooth mass index-is more strongly thickness, identify suitable indicator decreasing in healthy elderly individuals.Grip strength, walking speed, body weight, index, loss, at rest during contraction were determined 97...
Summary Background The tongue is responsible for compressing food against the palate and squeezing it into pharynx during oral preparatory phase of swallowing. Tongue pressure ( TP ), an indicator muscle strength, has been observed to decline with age; maximum occlusal force MOF chewing ability, correlated . However, no study investigated relationship between Objective To investigate correlation according age in healthy individuals. Methods We retrospectively collected handgrip strength HGS...
Background/Objectives: The diaphragm is important for respiration, but the effects of age-related muscle loss and sarcopenia on function are unclear. We evaluated associations skeletal mass (SMM) with function. Methods: This study was conducted at three Japanese hospitals from May 2023 to September 2024. participants underwent bioelectrical impedance SMM assessment, as well pulmonary tests. Diaphragm ultrasound used measure thickness functional residual capacity (FRC), thickening fraction...
Abstract Background Aspiration pneumonia, which often recurs due to dysphagia, worsens as patients move between homes, facilities, and hospitals. The impact of pre-hospital living setting on oral intake at discharge remains unclear. purpose this study was identify the effects nutritional route upon in older with aspiration pneumonia. Methods This prospective cohort included aged ≥ 65 years who were admitted an acute care hospital diagnosed Patients followed up until or death during...
We hypothesized that community-dwelling older adults with impaired swallowing functions have a higher risk of social isolation than individuals without function. The aim this study was to identify the association dysphagia in home care patients using daily interaction frequency and laughter as indicators interaction. One hundred ninety patients, aged ≥65 years, were included cross-sectional questionnaire survey. patients' basic information, level required, background percentage public health...
We conducted a clinical cross-sectional study to examine the relationship between jaw-opening force and area of suprahyoid muscles whole skeletal muscle mass. Subjects were healthy 39 males 51 females without dysphagia sarcopenia, aged 65 years older. Jaw-opening was measured three times using sthenometer; maximum these taken as measurement value. The geniohyoid anterior belly digastric evaluated ultrasonography. mass index, gait speed grip strength according diagnostic criteria Asian...
Abstract Objectives This cross‐sectional study aimed to examine the oral health of malnourished acute‐care hospital inpatients, who were subjects a nutritional support team (NST). We also elucidate systemic and factors associated with those patients. Background Interventions by NST are essential for inpatient nutrition management require active participation dental professionals. However, information is limited regarding state among acute‐stage inpatients. Materials Methods enrolled 255...
Swallowing function is associated with systemic factors. Whether trunk or appendicular skeletal muscle mass a better indicator of swallowing-related characteristics in community-dwelling older adults not clear. Hence, we investigated the association between muscles (e.g., and quality) mass. Community-dwelling aged ≥ 65 years (n = 141; men: n 45, women: 96) were recruited for this cross-sectional observational study via health survey conducted 2018. Trunk index (TMI) (SMI) measured using...
Enteral nutrition for children is supplied through nasogastric or gastrostomy tubes. Diet not only influences nutritional intake but also interacts with the composition and function of gut microbiota. Homemade blenderized tube feeding has been administered to receiving enteral nutrition, in addition ready-made feeding. The purpose this study was evaluate oral/gut microbial communities without homemade Among a total 30 children, 6 mainly (RTF) 5 (HBTF) were analyzed study. Oral microbiota...
Patients lose their voice after laryngectomy for laryngeal cancer or aspiration prevention surgery severe dysphagia. To assist such patients, we developed and verified the utility of a novel vocalization method using device termed retriever (VR), in which sound source is placed mouth.
The tongue plays an important role during the oropharyngeal phase of swallowing. Each part has a different function Ageing causes changes in muscle quantity and quality. Qualitative changes, such as increase intramuscular adipose tissue, can be determined by echo intensity (EI) on ultrasonography (US).To clarify relationship between EI thickness tongue.Ninety-four healthy elderly individuals (30 male, 64 female) aged >65 years (mean 71.10 ± 4.13 years) were enrolled. Tongue (TT) US. was...
Introduction: The aim of this study was to determine the associations time spent away from bed with whole-body muscle mass and swallowing function in older adults low activities daily living (ADL). Methods: This cross-sectional conducted at Tokyo Medical Dental University included over 65 years age who underwent a medical intervention their residence. Data regarding age, sex, body height weight, activity status, history, bed, Functional Oral Intake Scale (FOIS) were collected. We calculated...
Stroke and poor oral health are common in older people, the brain injuries associated with stroke often accompanied by a decline function. In this study, we investigated characteristics of patients who could not recover ingestion until discharge association between improved health, swallowing function, nutritional intake methods acute care. The subjects were 216 consecutive admitted to Tokyo Medical Dental University hospital received management. Nutritional intake, dysphagia, evaluated...
This study aimed to investigate the effects of administration xanthan gum-based fluid thickener on regulation postprandial blood glucose level, gene expression in gastrointestinal tract, and gut microbiome. Six-week-old Sprague-Dawley rats were divided into two groups: with (Th group) without (Co a for 5 wks. Blood levels at 60 90 min after substantially decreased Th group. Glp1 Glp1r ileum was significantly upregulated continuous thickener. RNA-seq analysis revealed that cholesterol...
Mastication is a complicated task that involves the teeth and perioral muscles, such as tongue lip. Previous studies have shown correlations between masticatory performance muscle strength (eg pressure) occlusal forces.To investigate relationships characteristics.Forty-nine healthy young subjects (men: 24 women: 25) with Eichner classification group A were included in this cross-sectional study. Age, body weight, performance, masseter thickness, echo intensity, area of geniohyoid muscle,...
