EMG Lesion Localization and Characterization: A Case Studies Approach takes a unique approach to electrodiagnostic (EDX) medicine, using case studies and exercises to teach clinical reasoning and build technical skills. The first section presents basic principles, reviewing pertinent nerve and muscle anatomy, physiology, and pathophysiology along with study techniques, measurements, and pitfalls. The second section emphasizes how to most effectively utilize the book’s featured case studies, followed by 60 cases covering the range of disorders encountered in the EMG lab and organized by regional and multiregional disorders of the upper and lower extremities, brachial plexopathies, generalized disorders, and challenging cases. Through the EDX case studies, lesion localization and characterization are demonstrated and discussed step-by-step using a floating text box that tracks the findings for each case. Cases begin with the clinical features, which dictate the initial EDX studies performed. The results of those studies drive the next round of testing, which continues until the abnormality has been localized and characterized and a diagnosis is made. In this manner, the dynamic nature of electrodiagnostic testing and process of sequential study analysis is reinforced, just as it would be in the EMG laboratory. Authored by two leading experts in neurology and electrodiagnostic medicine, all aspects of lesion localization and characterization are extensively covered, including calculations of lesion severity for demyelinating conduction block and axon loss lesions and calculations of various types of motor unit action potential recruitment frequencies. The book features a large number of anatomical drawings, charts, and EDX images in order to illustrate the skills of lesion localization and characterization comprehensively. By conveying the “cognitive approach” to EDX medicine, EMG Lesion Localization and Characterization merges clinical knowledge with real-life cases to better instruct residents, fellows, technicians, and neuromuscular providers in the field of electrodiagnostic medicine. Key Features: Includes 60 cases covering all major neuromuscular disorders Presents basic and advanced anatomic, physiologic, pathophysiologic, and temporal principles and concepts pertinent to EDX medicine EDX studies are evaluated as they are collected, providing insight into the principles underlying electrodiagnostic medicine Through sequential step-by-step analysis of findings, the decision-making process required in the EMG laboratory is simulated Purchase includes access to the ebook for use on most mobile devices or computers

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by nerves and muscles. Interpreting EMG is a mandatory skill for neurologists and rehabilitation specialists. This textbook provides the reader with a detailed discussion of the concepts and principles underlying electrodiagnostic medicine. It is written for an audience without pre-existing knowledge in this discipline, including beginner technicians and physicians in training. It is an ideal review for seasoned practitioners and those preparing for board examinations. It begins with a review of the foundational sciences and works through the field in twenty chapters, including a large number of case studies demonstrating correct application and interpretation. Appendices of information frequently required in the EMG laboratory, such as Nerve Conduction Study techniques and their age-related normal values, anatomic regions assessed by each NCS and needle EMG studies, safety issues, and other important topics, are also included.

This atlas serves as a comprehensive working reference for a wide range of clinicians practicing in the field of clinical neurophysiology, including adult and pediatric neurologists, epileptologists, neurocritical care specialists, and electroneurodiagnostic technologists. Covering EEG, EMG, MEG, evoked potentials, sleep and autonomic studies, and ICU, critical care, and intraoperative monitoring, expert authors share examples of common and novel artifacts and highlight signature features to help practitioners recognize patterns and make accurate distinctions. This visual compendium of information in atlas format addresses the artifact in all areas of clinical neurophysiology and highlights the traps and pitfalls that can taint studies and lead to misdiagnosis if not properly identified. Atlas of Artifacts in Clinical Neurophysiology provides full-page examples of waveforms and recordings to enhance appreciation of the nuances involved in distinguishing artifacts from neurological findings that require intervention. With the most up-to-date information available on artifacts present during procedures in both adult and pediatric patients, this book provides readers with an in-depth understanding of artifact interpretation that is essential to any clinician working in the field of clinical neurophysiology given the ubiquitous nature of artifact during electrophysiological recording. Key Features: The only dedicated reference on artifacts in all areas of clinical neurophysiologic testing Large-format examples of both common and unusual artifacts encountered in each procedure category Up-to-date text in each chapter provides greater depth of explanation Draws on the expertise and clinical wisdom of leading practitioners to develop mastery in recognizing artifacts and avoiding diagnostic pitfalls Includes access to the digital ebook and 19 videos

This title in the popular Pearls Series focuses on electrodiagnostic studies of neuromuscular diseases. EMGs and their interpretation are a major component of the specialty of physical medicine and rehab physicians, and they are important to neurologists and electromyographers. For each case, patient information is presented, the EMG findings are discussed, and the reader is asked to make a diagnosis based on these findings. The next page reveals the diagnosis, discussed the case and the medical condition in question, and then presents 3-4 pearls of practice distilled from the case. Pearls books feature real patient cases, providing information not found in standard texts Each case follows the same format for clarity and ease of presentation Provides information about the specific patient as well overall information on each disorder discussed. The text is interactive as the reader is asked make a diagnosis based on the case information presented Illustrations are provided for most of the cases Three or four "pearls of practice" are distilled for each case.

Clinical Neurophysiology, Third Edition will continue the tradition of the previous two volumes by providing a didactic, yet accessible, presentation of electrophysiology in three sections that is of use to both the clinician and the researcher. The first section describes the analysis of electrophysiological waveforms. Section two describes the various methods and techniques of electrophysiological testing. The third section, although short in appearance, has recommendations of symptom complexes and disease entities using electroencephalography, evoked potentials, and nerve conduction studies.

Revised, updated, and expanded second edition of the premier learning guide for residents, McLean EMG Guide emphasizes skills and concepts required for success in mastering basic electrodiagnostic techniques. This step-by-step approach to performing and interpreting EMG and nerve conduction studies will prepare trainees, fellows, and attendings to meet the challenges encountered in daily practice with confidence. The book is broken into short formatted chapters covering instrumentation, basic nerve conduction and needle EMG techniques, interpretation, applications for common clinical problems, and a new chapter on ultrasound. The procedures are laid out as illustrated tables with specifics for lead placement, stimulation, sample waveforms, and photographs to guide electrodiagnostic set-ups. Clinical presentation, anatomy, recommended studies, normal values, pearls and tips, and key findings are presented throughout in bulleted text for a thorough, more focused guidebook. Multiple choice questions and answers with rationales reinforce learning for those wishing to review concepts through self-guided assessment.
