BACKGROUND AND PURPOSE Spontaneous swallowing frequency has been described as an index of dysphagia in various health conditions. This study evaluated the potential of spontaneous swallow frequency analysis as a screening protocol for dysphagia in acute stroke. METHODS In a cohort of 63 acute stroke cases, swallow frequency rates (swallows per minute [SPM]) were compared with stroke and swall...

The purpose of this study was to compare cerebral cortical representation of experimentally induced reflexive swallow with that of volitional swallow. Eight asymptomatic adults (24-27 yr) were studied by a single-trial functional magnetic resonance imaging technique. Reflexive swallowing showed bilateral activity concentrated to the primary sensory/motor regions. Volitional swallowing was repre...

Abstract Purpose The primary goal of this study was to establish a normative data set representing intraoral time series swallow pressure profiles for healthy adults using novel wearable sensing system, OroPress, developed help with dysphagia (swallow disorder) clinical screening. Methods Swallow pressure-time 35 (17 male, 18 female) swallowing water ( $$3 \times 5\, {\text{cm}^3}$$ <mml:math x...

OBJECTIVE/HYPOTHESIS We hypothesize that the central response during swallowing rehabilitation is critical and may be exploited to maximize the therapeutic benefit. We seek to provide preliminary data regarding the neural networks associated with commonly employed rehabilitation strategies to increase our understanding of the neural bases underlying these maneuvers. STUDY DESIGN Case series. ...

We have compared barium swallow with a radionuclide gastro-oesophageal scintigraphy (milk scan) method of detecting gastro-oesophageal reflux in 26 infants. In 17 cases, presenting as near miss sudden infant death syndrome, reflux was detected in 2 by barium swallow and in 8 by scintigraphy. In the remaining 9 infants with suspected pulmonary aspiration, reflux was demonstrated by barium swallo...

Infant suckling is a complex behavior that includes cycles of rhythmic sucking as well as intermittent swallows. This behavior has three cycle types: 1) suck cycles, when milk is obtained from the teat and moved posteriorly into the valleculae in the oropharynx; 2) suck-swallow cycles, which include both a rhythmic suck and a pharyngeal swallow, where milk is moved out of the valleculae, past t...
