INTRODUCTION Manual laborers are at increased risk for carpal tunnel syndrome (CTS), and a combination of history, physical examination, and nerve conduction studies is often used to screen for CTS in this population. Neuromuscular ultrasound may be a better screening tool, because it is painless. In this study we compare the accuracy of nerve conduction studies and ultrasound for CTS screening...

Denervation of oropharyngeal muscles in obstructive sleep apnea (OSA) has been suggested by needle electromyography (EMG) and muscle biopsy, but little is known about oropharyngeal nerve conduction abnormalities in OSA. We sought to compare hypoglossal nerve conduction studies in patients with and without OSA. Unilateral hypoglossal nerve conduction studies were performed on 20 subjects with OS...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

Previously, it has been demonstrated that auditory stimulation with music (Traeumerei [TM] by Schumann) decreased renal sympathetic nerve activity (RSNA) and blood pressure (BP) with a central mechanism, while it is unknown whether TM affects parasympathetic nerve activity. Here, the effects of auditory stimulation with TM on gastric vagal nerve activity (GVNA) in urethane-anesthetized rats wer...

There is substantial evidence supporting the role of aspartate or glutamate as the neurotransmitter of the auditory nerve. The concentration of aspartate aminotransferase (L-aspartate:2-oxoglutarate aminotransferase, EC 2.6.1.1), an enzyme associated with the metabolism of these amino acids, is high in axons and terminals of the auditory nerve. Antibodies were raised against aspartate aminotran...

We studied the effects of vibration exposure on the peripheral nerve system by measuring and comparing motor nerve conduction velocity, sensory nerve conduction velocity and residual latency in 236 vibrating tool operators and 30 normal controls of the same age-distribution. In addition, thresholds of pain and vibratory sense were examined and subjective complaints were also determined by quest...

Since Merrit and Putnam (1938) 8 introduced the diphenylhydantoin (DPH) in the treatment of epilepsy, it has been used largely as the main drug in many forms of the disease. Several attempts have been made to demonstrate its action on the peri­ pheral nerve, but the obtained results are controversial. Korey 6 first, and Morrell, Bradley and Ptashne after, gave experimental evidence of DPH toxic...

This report reviews the fundamental principles and the changing concepts of nerve stimulation techniques, and discusses the proper application of these techniques in the differential diagnosis of peripheral nerve disorders. Nerve conduction studies help delineate the extent and distribution of the neural lesion and distinguish two major categories of peripheral nerve disease: demyelination and ...

Thirty-one chronic alcoholic patients were investigated using quantitative electrophysiological techniques. Estimates of the numbers of functioning motor units in the extensor digitorum brevis muscles and measurements of the parameters of the potentials of these units are presented along with the values for motor nerve conduction velocities in the innervating lateral popliteal nerves. Motor con...

INTRODUCTION Differing patterns of neurophysiological abnormalities have been reported in patients with Fisher syndrome. Fisher syndrome is rare, and few series have incorporated prospective serial studies to define the natural history of nerve conduction studies in Guillain-Barré syndrome. METHODS In an ongoing prospective study of Guillain-Barré syndrome patients, patients who presented wit...
