OBJECTIVE To compare the swallowing functions according to the lesion locations between brain tumor and stroke patients. METHODS Forty brain tumor patients and the same number of age-, lesion-, and functional status-matching stroke patients were enrolled in this study. Before beginning the swallowing therapy, swallowing function was evaluated in all subjects by videofluoroscopic swallowing st...

Objective numerical data on swallowing function are needed to aid in eating and swallowing intervention and preventive rehabilitation. Using noninvasive methods, the influences of age and differences in size of water bolus on laryngeal activity and respiratory activity were examined in healthy young and older women. Swallowing function was influenced by age and bolus size. Influence of bolus si...

We evaluated impedance pharyngography (IPG), a new method to assess swallowing function based on changes in the electrical impedance of the neck during swallowing. The electrical impedance of the neck, recorded by the 4-electrode method, changed with the equivalent cross-sectional area of the route of the electric current due to reflex activities of related organs during swallowing. IPG wavefor...

Swallowing disorder, also called dysphagia, is a common complication caused by strokes. The dysphagic patients usually have clinical problems such as choking, malnutrition, significant weight loss, and aspiration pneumonia. Surface electromyography(EMG) provides a simple, non-radioactive, and non-invasive method to measure the muscle activity patterns during swallowing to describe physiology of...

BACKGROUND Head position practice has been shown to influence pill-swallowing ability, but the impact of head position on measures of swallowing outcomes has not yet been studied with fiber-optic endoscopic evaluation of swallowing (FEES). The primary purpose of this study was to determine whether head position impacts penetration-aspiration scale scores and/or post-swallow pharyngeal residue a...

BACKGROUND Hyperorality, compulsive eating and aspiration because of food gorging, has been described in patients with frontotemporal lobar dementia (FTLD), but swallowing function in this population has not been reported. OBJECTIVE To identify the swallowing status in a sample of patients with FTLD. DESIGN Case series. SETTING Referral center, ambulatory care. PATIENTS A consecutive se...

BACKGROUND It remains unclear how swallowing assessment can help clinicians to predict the risk for pneumonia in elderly persons after ischemic stroke. A prospective case-control study was conducted to evaluate the prognostic utility of swallowing ability assessments. METHODS Participants were 136 elderly persons who had an acute ischemic stroke 3-12 months previously. They were separated int...

There have been studies that investigated mandibular movements and positioning during swallowing, but the results were inconsistent, and still the exact position of the condyles during swallowing is unknown. The purpose of this investigation was to study the kinematics of the mandible and the condyles, and to determine the actual movement paths and position of mandible and condyles during the p...

BACKGROUND Recently, the number of thyroid surgery cases has been increasing; consequently, the number of patients who visit plastic surgery departments with a chief complaint of swallowing deformity has also increased. We performed a scar correction technique on post-thyroidectomy swallowing deformity via platysma flap with Z-plasty and obtained satisfactory aesthetic and functional outcomes. ...

Introduction Voice modification after swallowing may indicate changes in the transit of the bolus. Objective The aim of this study is to verify the use of perceptual voice analysis to detect oropharyngeal dysphagia. Study Design Case series. Methods Twenty-seven patients with dysphagia as diagnosed by videofluoroscopy and 25 without were evaluated. The sustained vowel /a/ was recorded before th...
