Recently, as diagnostic aids of neurological science, not only electromyography but also other techniques such as motor nerve conduction velocity, evoked potentials and strength-duration curve have been performed. In this paper, the first, the standard value of conduction velocities and the critical value of reduced conduction velocities in pathologic condition were discussed, because the probl...

introduction: lasers, light emitting diodes (leds) and super luminous diodes (slds) are widely used to treat selected musculoskeletal, integumentary and neurological conditions. the mechanisms underlying the reported treatment effects of light therapy are unclear and the physiologic effect of light on a variety of tissues, particularly neurological, is mostly unknown. a few researchers have rep...

Diabetes mellitus produces marked abnormalities in motor nerve conduction, but the mechanism is not clear. In the present study we hypothesized that in the streptozotocin (STZ)-induced diabetic rat impaired vasodilator function in arterioles that provide circulation to the region of the sciatic nerve is associated with reduced endoneural blood flow (EBF) and that these defects precede slowing o...

Tibial motor nerve conduction velocity was measured in rats, before and two months after the induction of diabetes with streptozotocin. A second group of diabetic animals was also administered 1% dietary myoinositol supplements. An analysis of variance was performed on these data. Myoinositol supplements had no effect whatsoever. The period of diabetes had a statistically significant and quanti...

Nerve conduction studies have become an important non invasive tool for diagnosis of nerve lesions. Among the various factors affecting nerve conduction gender may have a significant role. This study was planned to study the effect of gender on various parameters of nerve conduction. Nerve conduction study data of 30 males and female subject was obtained retrospectively from the lab records and...

Electromography, motor, sensory and mixed nerve conduction velocity, and H reflex were studied in four patients with ataxia-telangiectasia. The earliest and most striking electrophysiologial finding was the reduced amplitude of evoked nerve potentials. In the oldest patient, findings suggestive of spinal atrophy and mild reduction of the motor and sensory nerve conduction velocities were found....

H-reflexes in normals were elicited by percutaneous electrical and magnetic stimulation of proximal nerve roots at the cauda equina. H-M interval to S1 nerve root stimulation at the level of the S1 foramen was 6.8 +/- 0.33 ms, with side to side difference of 0.16 +/- 0.13 ms. Compression/ischemia of the sciatic nerve in the mid-thigh abolished the H-reflex to stimulation of the tibial nerve at ...

A complete and accurate description of the conduction properties of the entire population of nerve fibers within a peripheral nerve bundle has long been an important objective of clinical neuromuscular electrophysiology. Access to such information would increase the sensitivity and specificity of neuromuscular electrodiagnostics, and provide improved means of assessing nerve development, growth...

OBJECTIVE Adrenomyeloneuropathy (AMN) is an X linked metabolic disorder presenting with progressive spastic paraparesis in the third to fifth decade of life. Although peripheral neuropathy is also present in most patients, prominent pyramidal signs may make its clinical recognition difficult. The objective was to characterise the peripheral neuropathy in patients with AMN by nerve conduction st...

Evidence for the important role of the potent oxidant peroxynitrite in peripheral diabetic neuropathy and neuropathic pain is emerging. This study evaluated the contribution of neuronal nitric oxide synthase (nNOS) to diabetes-induced nitrosative stress in peripheral nerve and dorsal root ganglia, and peripheral nerve dysfunction and degeneration. Control and nNOS-/- mice were made diabetic wit...
