Anterior open bite (AOB) and tongue thrust swallowing are frequently associated, but the relationship between the two remains unclear. Electropalatography (EPG), which is used in speech pathology to measure dynamic tongue function for diagnostic, therapeutic, and research purposes, is a suitable technique for the investigation of this relationship. The present clinical study examined the dentof...

To examine whether motor commands of two or more distinct laryngeal motor patterns converge onto a common premotor network, we conducted dual recordings from the laryngeal adductor motoneuron and its premotor neuron within the brainstem respiratory circuitry during fictive breathing, coughing, sneezing, and swallowing in decerebrate paralyzed cats. Expiratory neurons with an augmenting firing p...

Deoxynivalenol (DON), one of the most abundant mycotoxins found on cereals, is known to be implicated in acute and chronic illnesses in both humans and animals. Among the symptoms, anorexia, reduction of weight gain and decreased nutrition efficiency were described, but the mechanisms underlying these effects on feeding behavior are not yet totally understood. Swallowing is a major motor compon...

INTRODUCTION During the aging process, one of the functions that changes is swallowing. These alterations in oropharyngeal swallowing may be diagnosed by methods that allow both the diagnosis and biofeedback monitoring by the patient. One of the methods recently described in the literature for the evaluation of swallowing is the Sonar Doppler. OBJECTIVE To compare the acoustic parameters of o...

UNLABELLED Purpose To analyze the effect of the age group and food's consistency according to the qualitative and quantitative ultrasonographic parameters in the oropharyngeal swallowing. METHODS Ultrasonographic evaluations of swallowing were performed in 100 health individuals (divided into four groups, whose age brackets were 20-60 years), using liquid and mashed consistencies. For qualita...

INTRODUCTION  Spinocerebellar ataxia (SCA) is a degenerative disease that can cause loss of coordination of voluntary muscle movement such as that required for swallowing. AIMS  The purposes of this cross-sectional and comparative case study were: (1) to assess the severity of dysphagia through a videofluoroscopic swallow study, and (2) to compare differences in frequency, intensity, and dura...

PURPOSE Outcomes from studying the coordinative relationship between respiratory and swallow subsystems are inconsistent for sequential swallows, and the lung volume at the initiation of sequential swallowing remains undefined. The first goal of this study was to quantify the lung volume at initiation of sequential swallowing ingestion cycles and to identify the respiratory pattern(s) surroundi...

Early work on representational specificity and recent findings on temporomandibular joint (TMJ) movement representation raise doubts that a specific swallow representation does exist. Additionally, during cortical stimulation TMJ movements and swallowing show a high overlap of representational areas in the primary motor cortex. It has thus been hypothesized that they overall might share the sam...

PURPOSE To analyze the difference between nonsmokers and smokers on the changes in the perceptions of smell and taste and to verify the influence of these aspects in the emergence of compensatory movements during swallowing. METHODS To evaluate these aspects, capabilities of olfactory and gustatory recognition were observed, as well as the compensation swallowing. Twenty-four patients were ev...
