BACKGROUND AND PURPOSE We have investigated the pathophysiological mechanisms of dysphagia in Wallenberg's syndrome (WS) that are due to lateral medullary infarction (LMI). METHODS Twenty patients with WS were evaluated by means of clinical and electrophysiological methods that measured the oropharyngeal phase of voluntarily initiated swallowing. For(More)
The electrophysiological features of voluntarily induced and reflexive/spontaneous swallows were investigated. In normal subjects, swallows were elicited by infusing water either into the mouth (1-3 ml) or directly into the oropharyngeal region through a nasopharyngeal cannula (0.3-1 ml). For water infused orally, subjects were either requested to swallow(More)
We studied the various physiological aspects of oropharyngeal swallowing in Parkinson's disease (PD). Fifty-eight patients with PD were investigated by clinical and electrophysiological methods that measured the oropharyngeal phase of swallowing. All patients except 1 had mild to moderate degree of disability score. Dysphagia was demonstrated in 53% of all(More)
OBJECTIVE Neurogenic dysphagia (ND) is a prevalent condition that accounts for significant mortality and morbidity worldwide. Screening and follow-up are critical for early diagnosis and management which can mitigate its complications and be cost-saving. The aims of this study are to provide a comprehensive investigation of the dysphagia limit (DL) in a(More)
This study describes the pain characteristics of the chronic migraine, including duration, intensity, quality, aggravation by activity, associated features in a headache clinic. One hundred twenty-one chronic migraine patients were evaluated. A total of 79% patients were female, and the mean age was 43.6 years, ranging from 19.0 to 54.2 years. The pain(More)
Healthy adults can swallow boluses of 20 ml water in a single swallow. Individuals with impaired swallowing, however, may be unable to do so, instead requiring two or more swallows; this phenomenon is called "piecemeal deglutition". The term "dysphagia limit" refers to the volume at which piecemeal deglutition occurs. The aim of our study was to investigate(More)
STUDY AIMS Autonomic changes, especially those of sympathetic skin responses (SSR), during sequential water swallowing (SWS) have not been systematically investigated. This study aims to electrophysiologically examine these autonomic changes (SSR and heart rate) that occur during 50 ml sequential water swallowing from a cup. MATERIALS AND METHODS(More)
Recently it has been proposed that corticobulbar innervation of the lower facial muscles is bilateral, that is from both right and left sides of the motor cortex. The objectives of this study were, i) to evaluate the corticonuclear descending fibers to the perioral muscles and, ii) to determine how central facial palsy (CFP) occurs and often recovers(More)
Swallowing mechanism and neurogenic dysphagia in MS have been rarely studied by electromyographical (EMG) methods. This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18(More)
OBJECTIVE Cricopharyngeal (CP) muscle of the upper oesophageal sphincter (UES) has a significant role in the pharyngo-esophageal phase of deglutition. The linkage between the CP muscle of UES and the motor cortex has not been previously studied electrophysiologically in healthy humans and in patients with neurogenic dysphagia. METHODS Needle recordings of(More)
