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...

OBJECTIVE To investigate the validity and reliability of the Swallowing Assessment of Saliva in detection of aspiration risk. DESIGN Validation study. SETTING Inpatient neurorehabilitation centre. SUBJECTS Adult patients with acquired brain injury. A total of 43 patients for concurrent validity and 33 other patients for inter-rater reliability. INTERVENTIONS Concurrent validity was esta...

BACKGROUND Swallowing coordination is affected by cortical and subcortical inputs from the central nervous system. Our hypothesis is that the swallowing dynamics may be influenced by gender. AIM To evaluate the influence of gender on water swallowing dynamics. METHODS We studied 111 health subjects, 36 men, aged 24-77 years (mean: 46.3 +/- 16.1 years) and 75 women, aged 22-75 years (mean: 3...

Most anurans retract and close their eyes repeatedly during swallowing. Eye retraction may aid swallowing by helping to push food back toward the esophagus, but this hypothesis has never been tested. We used behavioral observations, cineradiography, electromyography and nerve transection experiments to evaluate the contribution of eye retraction to swallowing in the northern leopard frog, Rana ...
