A complete overview of electromyography with contributions from pacesetters in the field In recent years, insights from the field of engineering have illuminated the vast potential of electromyography (EMG) in biomedical technology. Featuring contributions from key innovators working in the field today, Electromyography reveals the broad applications of EMG data in areas as diverse as neurology, ergonomics, exercise physiology, rehabilitation, movement analysis, biofeedback, and myoelectric control of prosthesis. Bridging the gap between engineering and physiology, this pioneering volume explains the essential concepts needed to detect, understand, process, and interpret EMG signals using non-invasive electrodes. Electromyography shows how engineering tools such as models and signal processing methods can greatly augment the insight provided by surface EMG signals. Topics covered include: Basic physiology and biophysics of EMG generation Needle and surface electrode detection techniques Signal conditioning and processing issues Single- and multi-channel techniques for information extraction Development and application of physical models Advanced signal processing techniques With its fresh engineering perspective, Electromyography offers physiologists, medical professionals, and students in biomedical engineering a new window into the far-reaching possibilities of this dynamic technology.

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

Beautifully and lavishly illustrated, Atlas of Nerve Conduction Studies and Electromyography demystifies the major conditions affecting peripheral nerves and provides electrodiagnostic strategies for confirming suspected lesions of the peripheral nervous system. Building on the success of the landmark Atlas of Electromyography, this new text is divided into sections based on the major peripheral nerves. It contains detailed illustrations of each nerve along with a discussion of its anatomy, followed by a thorough outline of the clinical conditions and entrapment syndromes that affect the nerve, including a list of the etiologies, clinical features, and electrodiagnostic strategies used for each syndrome. Routine and special motor and sensory nerve conduction studies are shown in an anatomical illustration. In addition, each muscle supplied by the peripheral nerve is illustrated showing the root, plexus, and peripheral nerve supply to the muscle and is accompanied by a corresponding human photograph. Written text provides information about the nerve conduction studies, muscle origin, tendon insertion, voluntary activation maneuver, and the site of optimum needle insertion, which is identified in the figures by a black dot or a needle electrode. Atlas of Nerve Conduction Studies and Electromyography is the perfect anatomical guide for neurologists, specialists in physical medicine and rehabilitation, and electrodiagnostic medicine consultants, while also providing support for individuals in residency training programs, critical care medicine, neurological surgery, and family practice.
