Book excerpt: Appropriately select, implement, and interpret electrodiagnostic tests to identify a full range of central and peripheral nervous system disorders with Aminoff’s Electrodiagnosis in Clinical Neurology! Covering everything from basic principles to the latest advances in electrodiagnosis, this medical reference book helps you make optimal use of this powerful but complex diagnostic modality in compliance with regulatory and professional standards, so you can diagnose patients accurately and initiate effective treatment and management strategies. Deepen your understanding of the principles, scope, limitations, diagnostic importance, prognostic relevance, and complications for each technique. Visually grasp the technical and practical aspects of electrodiagnostic tests with almost 800 charts, figures, and tables. Rely on the knowledge, experience, and perspective of renowned expert Dr. Michael J. Aminoff and an international team of contributors comprised of a virtual "who’s who" of clinical neurophysiology. Keep up with developments in the field through significant updates, including new chapters on Artifacts and Normal Variants in the Electroencephalogram; Microneurography; Clinical Applications of Nerve Excitability Testing; Ultrasound of Muscle and Nerve; The Blink Reflex and Other Brainstem Reflexes; Visual Evoked Potentials, Electroretinography and Other Diagnostic Approaches to the Visual System; and Magnetic Stimulation in Clinical Practice and Research.
