Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

Acute axonal polyneuropathy and Wernicke-Korsakoff encephalopathy developed simultaneously in three patients. Nerve conduction studies (NCS) detected markedly decreased compound muscle action potentials (CMAPs) and sensory nerve action potentials (SNAPs) with minimal conduction slowing; sympathetic skin responses (SSRs) were also notably decreased. Sural nerve biopsies showed only mild axonal d...

background : determining the validity of current median sensory nerve conduction techniques for diagnosis of carpal tunnel syndrome (cts). methods: eighty five patients with clinical diagnosis of cts were compared with the same number of healthy people. the validity of electrodiagnostic tests were compared in a case-control manner. these electrodiagnostictechniques included long-segment, short-...

Direct stimulation of 23 median, 13 ulnar and 2 peroneal nerves at the time of surgical exploration has been used to locate, and characterize the conduction abnormalities in the nerves. The most frequent location of the major conduction abnormalities in the median nerve was in the first 1-2 cm distal to the origin of the carpal tunnel. In the ulnar nerve the important conduction abnormalities w...

The aim of this study was to describe motor nerve conduction velocity in upper and lower extremities in sportsmen. Fifteen high-level field hockey players, seventeen soccer players and ten tennis players were recruited from the Polish National Field Hockey League, Polish Soccer League Clubs, and Polish Tennis Association clubs,respectively. The control group comprised of seventeen healthy, non-...

Many of the disabling fea tures of leprosy ~re caused by peripheral nerve impairment involving both sensory and motor modalities. Pathologic changes in an affected nerve are usually seen at a site where the nerve passes over a bone or joint, or where the nerve is superficial. In the arm the most commonly involved nerves, in order of frequency, are the ulnar at the elbow and the median at the wr...

background: few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. case presentation: a 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. at ulrasonographic examination, a simple cyst was detected. sensory response of palmar cutaneous branch of median nerve was absent at the affected sid...

We examined two sibs with the classic form of Pelizaeus-Merzbacher disease (PMD) and their relatives. Electromyographic-electroneurographic studies and magnetic stimulation of motor pathways were performed. In both patients we found an absence of compound motor action potential (cMAP) after stimulation of the motor cortex and a normal conduction time by stimulating the cervical roots. Despite r...

Though peripheral conduction velocity is widely used to characterize afferent fibers according to somatosensory modality, disagreement exists as to whether or not conduction velocity varies along such an axon's length. Therefore, in this experiment, conduction velocities were measured over very short axonal segments (7.5 to 15 mm) within the posterior tibia1 nerve, sciatic nerve, and L7 dorsal ...

OBJECTIVES The boom in computer use and concurrent high rates in musculoskeletal complaints and carpal tunnel syndrome (CTS) among users have led to a controversy about a possible link. Most studies have used cross-sectional designs and shown no association. The present study used longitudinal data from two large complementary cohorts to evaluate a possible relationship between CTS and the perf...
