In an attempt to find the best electrophysiological indicator of improvement for the neuropathy present in patients with chronic renal failure undergoing hemodialysis, several types of nerve conduction were studied at the beginning of dialysis and six months later. Sural nerve conduction and late response latencies were recorded in addition to conventional motor and sensory nerve conductions. A...

Moosa, A., and Dubowitz, V. (1971). Archives of Disease in Childhood, 46, 852. Slow nerve conduction velocity in cretins. The ulnar and posterior tibial conduction velocities were measured in 6 untreated and 3 treated cretins. In 4 of the untreated patients, the conduction velocity of both nerves was slower than normal; in 1 patient the ulnar and in the other the posterior tibial nerve conducti...

BACKGROUND Nerve conduction studies are an invaluable aid to investigate and quantify the physiological activity of peripheral nerves. These include measurement of sensory and motor conduction velocities and latencies of peripheral nerves. These nerve conduction parameters may be affected by anthropometric factors like age, sex, height, weight and BMI. In this observational study the impact of ...

The influences of axon diameter, myelin thickness, and internodal length on the velocity of conduction of peripheral nerve action potentials are unclear. Previous studies have demonstrated a strong dependence of conduction velocity on internodal length. However, a theoretical analysis has suggested that this relationship may be lost above a nodal separation of ∼0.6 mm. Here we measured nerve co...

Nerve conduction study is an important tool to evaluate peripheral nerve abnormality. The primary purpose of this study was to provide normative electrophysiological data for commonly tested upper limb nerves in normal healthy adults. Nerve conduction studies were performed prospectively in upper limbs of 175 carefully screened healthy volunteers between the ages of 18 and 66 years using standa...

OBJECTIVE To determine an ideal stimulation site of the medial antebrachial cutaneous nerve (MACN) using ultrasound measurement and to compare the efficiency of the new stimulation site with the conventional stimulation site on the nerve conduction study. METHODS Both arms of 15 healthy participants were measured using ultrasound. The MACN was identified in the transverse view at each 0, 2, 4...

To investigate the physiological adjustments of textile workers exposed to high temperature environment, 10 workers with years of work experience and 12 students with rarely entering into workshop were chose to a hospital for blood test and nerve conduction velocity measurements. The blood test was to measure potassium content, sodium content, calcium content and bicarbonate content in particip...

The biological effects of omega-3 and omega-6 fatty acids are determined by their mutual interactions. This interaction extremely affects various functions. Lower consumption of omega-3 during gestation leads to various disorders, even in hearing. We aimed to assess the effect of low omega-3/omega-6 ratios on auditory nerve conduction. In this experimental study, the auditory brainstem response...

Near-nerve recording of sensory action potentials evoked by electrical and tactile stimuli is a valuable tool in the assessment of nerve pathophysiology. In most instances where percutaneous recording fails to discriminate sensory potentials from noise they can be picked up by needle recording. To localize the site of focal injuries by determination of conduction across the presumed site of les...

Conduction block was detected in patients with neuropathy by measuring a decrease in the size of the compound muscle action potential of more than 20% on proximal versus distal stimulation of the peroneal, median or ulnar nerve in the absence of excess temporal dispersion of the potential. The teased fibre analyses of nerve biopsies from four patients with "definite" and six patients with "prob...
