BACKGROUND Respiratory swallowing coordination is regarded as one of the several mechanisms by which the airway is protected from aspiration during swallowing. A lack of reciprocity between respiration and swallowing has been indicated as one of the mechanisms that can lead to aspiration and pneumonia. Since chronic obstructive pulmonary disease (COPD) is a pulmonary condition, we have hypothes...

A timed test of swallowing capacity has been designed for use in patients with neurogenic dysphagia. Swallowing speed (ml/s) has been demonstrated to have high intra- and inter- rater and test- retest reliability, and to be essentially independent of flavour or temperature. "Guideline" normal values were established in individuals without a swallowing disorder: swallowing speed was less in fema...

Background: the prolonged habit of pacifier sucking and the prolonged use of feeding bottle may cause myofunctional disorder, such as incorrect swallowing pattern and inadequate tongue rest position. Aim: to study the effect of myofunctional therapy (MFT) associated with the removal of the habit of pacifier sucking and the use of feeding bottle (REM) on the rehabilitation of swallowing and tong...

BACKGROUND The physiology of swallowing is characterized by a complex and coordinated activation of many stomatognathic, pharyngeal, and laryngeal muscles. Kinetics and electromyographic studies have widely investigated the pharyngeal and laryngeal pattern of deglutition in order to point out the differences between normal and dysphagic people. In the dental field, muscular activation during sw...

Simple, non-invasive equipment was designed to record respiratory patterns associated with swallowing food or drink in young and elderly healthy adults, to compare with neurologically impaired patients who complained of dysphagia. The timing of the entry of the test drink from a spoon into the mouth, the swallow event and respiration were recorded electronically and were presented in chart form...

OBJECTIVE To perform acoustic analysis of swallowing sounds, using a microphone and a notebook computer system, in healthy subjects and patients with dysphagia affected by neurological diseases, testing the positive/negative predictive value of a pathological pattern of swallowing sounds for penetration/aspiration. DESIGN Diagnostic test study, prospective, not blinded, with the penetration/a...

The aim of the present study was to investigate the adaptation of the swallowing reflex in terms of reduced swallowing reflex initiation following continuous superior laryngeal nerve stimulation. Forty-four male Sprague Dawley rats were anesthetized with urethane. To identify swallowing, electromyographic activity of the left mylohyoid and thyrohyoid muscles was recorded. To evoke the swallowin...

Objectives: The impairment of the temporomandibular joint and masticatory muscles has a negative impact on functions stomatognathic system, such as swallowing. Thus, an atypical swallowing pattern may contribute to development disorder (TMD). aim present study was evaluate acoustic aspects determine occurrence dynamics. Methods: Sixty-two individuals [16 males (25.8%) 46 females (74.2%); mean a...

Brain-derived neurotrophic factor (BDNF) acts as an anorexigenic factor in the dorsal vagal complex (DVC) of the adult rat brainstem. The DVC contains the premotoneurons controlling swallowing, a motor component of feeding behavior. Although rats with transected midbrain do not seek out food, they are able to swallow and to ingest food. Because BDNF and Tropomyosin-related kinase B receptors (T...
