Description

Ideal for DM and DNB in Neurology; Electrodiagnostic Laboratories; Neurologists and MD (Physiology, Psychiatry and Medicine)

Clinical neurophysiology has evolved as an extension of clinical examination. This book has three main parts of electrodiagnosis – nerve conduction, electromyography and evoked potentials. The emphasis is on correct method of conducting the test including pitfalls, precautions, and proper interpretation of the results. The normal values of various tests have been provided. The application of nerve conduction, electromyography and evoked potentials in various neurological disorders has been discussed for bedside application and clinical problem solving.

Key Features

The text is amply illustrated by relevant videos, CT and MRI scans, patients’ photographs, charts, and tables. The book also provides up-to-date review of relevant clinical and electrophysiological literature, and histopathological correlation with electrodiagnostic tests. These features make this book reader friendly for students and practitioners.
