Clinical neurophysiologic testing is an important component of evaluating patients with complaints that may be attributed to diseases of the central or peripheral nervous system. This classic volume in the Contemporary Neurology Series covers the basic concepts underlying each of the testing techniques and provides comprehensive descriptions of the methods and wide range of electrophysiologic testing available for patients with epilepsy, neuromuscular diseases, movement disorders, demyelinating diseases, sleep disorders, autonomic disorders and those undergoing orthopedic and neurosurgical procedures. This text details the role of each study, the interpretation of findings, and their application clinical problems. This text describes the multiple diagnostic procedures for diverse diseases of the neuromuscular system, including: electroencephalography (EEG); electromyography and nerve conduction studies; single fiber EMG; polysomnography; surface EMG patterns, blood pressure, pulse, sweat measures; vestibular function testing; deep brain stimulator physiology; and intraoperative monitoring. It is a practical textbook for neurologists, physiatrists and clinical neurophysiologists in clinical or research practice or in training. Key features of the new edition include fully updated chapters to reflect new research and techniques in clinical neurophysiology; updated images illustrating key elements of techniques and basic concepts; case examples for practical application.
