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 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)
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)
The nature of the oropharyngeal dysphagia in polymyositis/dermatomyositis (PM/DM) has been investigated by EMG methods. Nineteen patients with PM/DM were studied. The oropharyngeal phase of swallowing was evaluated by the electrophysiological methods measuring the laryngeal relocation time, pharyngeal transit time and the triggering of the pharyngeal phase(More)
BACKGROUND Sequential water swallowing (SWS) was mostly investigated by the videofluoroscopic and endoscopic methods. However some physiological features of SWS was rarely evaluated by neurophysiological techniques. Our aim was to investigate some neural and muscular changes on sequences of SWS using electromyography (EMG) methods. METHODS Fifty-eight(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)
OBJECTIVES The aim of this study is to describe patients with unusual symptoms that were primary manifestations of multiple sclerosis (MS). PATIENTS AND METHODS We report 21 multiple sclerosis patients who presented unusual initial pictures (acute brachial pain n=4, headache n=6, ptosis n=1, oculomotor nerve palsy n=1, peripheral facial palsy n=1, throat(More)
OBJECTIVES Brain death is the colloquial name for human death determined by tests showing irreversible cessation of the clinical functions of the brain. Spontaneous and reflex movements have been described in brain death. The aim of this report is to describe a brain-dead patient with unusual motor movements. DESIGN AND SETTING The patient was followed(More)
