Single unit potentials were recorded from sural and medial gastrocnemius nerves. Action potential amplitude, integrated area and half-width (duration) were approximately proportional to conduction velocity, raised to the powers 1.5, 1 and -0.5 respectively with the sural nerve, and 2, 1.5 and -0.5 for the medial gastrocnemius nerve. These empirical relationships were applied to the computation ...

The economic, social and personal burden of common neurological disorders has been the subject of intense study all over the world. Nerve conduction velocity being affected by factors like age, gender and temperature is a well known fact. The effect of handedness on nerve conduction is not known much and needs further evaluation. In the present study 50 medical students divided into 2 groups of...

Rabbit tibial nerves were subjected to direct, acute graded compression by means of an inflatable compression chamber. The acute and long term effects of 50, 200 and 400 mmHg applied for two hours on nerve function and nerve fibre structure were investigated. A pressure of 50 mmHg applied for two hours induced only minimal or no acute deterioration of maximal conduction velocity and nerve fibre...

The cardio-ankle vascular index (CAVI) is used to test vascular function and is an arterial stiffness marker and potential predictor of cardiovascular events. This study aimed to analyze the relation between objective indices of diabetic polyneuropathy (DPN) and the CAVI. One hundred sixty-six patients with type 2 diabetes mellitus were included in this study. We used nerve conduction studies (...

BACKGROUND Systemic lupus erythematosus (SLE) is an inflammatory, autoimmune, multiorgan disease often involving the central and peripheral nervous systems. OBJECTIVE To determine whether there is a selective small-diameter nerve fiber neuropathy in patients with SLE. DESIGN Cross-sectional study. SETTING Stavanger University Hospital, Stavanger, Norway. Patients Sixty patients with SLE, ...

introduction: diabetic polyneuropathy is one of the most common and important complications of diabetes mellitus for its clinical ranking. several clinical categorising scoring systems have been designated. among them only toronto clinical scoring system (tcss) had been partially evaluated on the basis of pathologic findings in sural nerve biopsy. only the mild cases had been studied since the ...

The abnormalities underlying diabetic neuropathy appear to be multiple and involve metabolic neuronal and vasomediated defects. The accumulation of long-chain fatty acids and impaired beta-oxidation due to deficiencies in carnitine and/or its esterified derivatives, such as acetyl-L-carnitine, may have deleterious effects. In the present study, we examined, in the diabetic bio-breeding Worceste...

BACKGROUND Peripheral neuropathy is one of the principal clinical disorders in workers with hand-arm vibration syndrome. Electrophysiological studies aimed at defining the nature of the injury have provided conflicting results. One reason for this lack of consistency might be the sparsity of published longitudinal etiological studies with both good assessment of exposure and a well-defined meas...

OBJECTIVES Metabolic disease affect all systems in the body, including the peripheral nervous system, but there is a controversy as whether to consider hyperlipidemia is a cause of peripheral neuropathy. The aim of the present study was to evaluate whether hyperlipidemic subjects with no clinical symptom or sign of peripheral neuropathy showed nerve conduction abnormalities or subclinical perip...

PURPOSE To investigate sensory nerve conduction of the caudal nerve in normal and diabetic rats. METHODS Diabetes was induced in twenty 8-weeks old Wistar male rats. Twenty normal rats served as controls. Caudal nerve conduction studies were made before diabetes induction and the end of each week for six consecutive weeks. The caudal nerve was stimulated distally and nerve potentials were rec...
