BACKGROUND Oropharyngeal dysphagia is common in individuals after stroke. Taste and temperature are used in dysphagia rehabilitation. The influence of stimuli, such as taste and temperature, on swallowing biomechanics has been investigated in both healthy individuals and in individuals with neurological disease. However, some questions still remain(More)
CONTEXT The effect of sour taste and food temperature variations in dysphagic patients has not been entirely clarified. OBJECTIVE To determine the effect of sour and cold food in the pharyngeal transit times of patients with stroke. METHODS Patients participating in this study were 30 right-handed adults, 16 of which were male and 14 were female, aged(More)
PURPOSE To determine the effect of sour flavor and cold temperature on oral transit time during swallowing. METHODS Participants were 52 subjects (28 male and 24 female) with ages between 50 and 80 years (median=66 years), after ischemic stroke involving right or left side damage and mild to moderate oropharyngeal dysphagia. Videofluoroscopy was performed(More)
Although accounting for 2% of body weight, brain has one of the greatest metabolic rates compared with other organs and systems. The energy metabolic consum is expended mainly in the maintenance of ionic gradient, essential to neuronal activity. Brain receives energy substrates from circulation, with interference of blood brain barrier (BBB). Glucose is the(More)
BACKGROUND The present study aimed to evaluate the relation between the National Institutes of Health Stroke Scale (NIHSS) score and the presence of laryngeal penetration and/or laryngotracheal aspiration in ischemic stroke patients and to verify what factors are predictors of the occurrence of pneumonia in the evaluated patients. METHODS This was an(More)
Cerebrovascular disease is recognized as to be associated with the highest mortality rate in Brazil. Dysphagia, speech and language disturbances are common consequences of the high incidence of stroke. Dysphagia is known to occur in at least 50% of the patients with acute stroke. The study is designed to establish the incidence of stroke in a reference(More)
Around 3% of the individuals with painful ophthalmoplegia have bilateral complaints. In the vast majority of these cases, appropriate investigation demonstrates a secondary etiology, and we are not aware of idiopathic cases reported. Herein we report a case of bilateral ophthalmoplegia where extensive investigation did not suggest a secondary cause.
There is controversy over how hormonal conditions influence cerebral physiology. We studied pattern-shift visual evoked potentials (PS-VEP), brain stem auditory evoked potentials (BAEP) and short-latency somatosensory evoked potentials (SSEV) in 20 female volunteers at different phases of the menstrual cycle (estrogen phase, ovulatory day and progesterone(More)
