Continuing the unique case-based learning approach to fill the gap between theory and practice, the third edition of Electromyography in Clinical Practice addresses the advances in neuromuscular medicine, including anterior horn cell disorders, peripheral neuropathies, neuromuscular junction disorders, and myopathies. It is the perfect resource for neurologists, physiatrists, neurosurgeons, orthopedic surgeons, rheumatologists, physical therapists, and pain management specialists, neuromuscular and clinical neurophysiology fellows, as well as the resident, trainee, and medical student interested in the diagnosis and management of the most common disorders encountered in the EMG lab.

This invaluable book for the electromyographer dispenses the latest techniques detailing methods of intramuscular electrode placement. The author examines the basic principles in electromyography (EMG) and includes updated information for the appendicular and axial muscles. It is divided into 14 sections organized by anatomical region: the muscles of the hand, forearm, arm, shoulder girdle, foot, leg, thigh, pelvis, hip joint, perineal region, paraspinal region, abdominal wall, the intercostals and diaphragm regions, along with the muscles innervated by cranial nerves. This information includes the innervations and attachments of each muscle, how to position the patient for examination, the appropriate site for insertion of the electrode, the depth of insertion for the electrode, and the action that the patient should perform to activate the muscle. The descriptions of the techniques used for rarely examined muscles are sufficient for a clinician to have the confidence needed to perform the procedure. Common errors in electrode placement and clinically relevant comments are illustrated and discussed, including cross-sectional illustrations on the appendicular muscles. A particularly useful inclusion is “Pitfalls” that describes which muscle the electrode will record if the needle is placed too deep, not deep enough, or not at the location described. The text contains a useful appendix, providing dermatomes of the limb and trunk, cutaneous innervations of the head, and excellent illustrations of both the brachial plexus and the lumbo-sacral-coccygeal plexus. The appendix also contains a useful table listing all muscles that are presented in the text with innervations from the peripheral nerve to the mixed spinal nerve root. Well organized, clearly and concisely written, this book remains a learning tool and excellent reference for electromyographers and for healthcare practitioners who are expanding their practice skills to include diagnostic EMG, as well as for graduate students who use EMG as part of their research.

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
Nine years have elapsed since the second edition of this book was published. In this time the principal advances in neuromuscular diseases have been in the application of molecular genetics to understanding the aetiology and pathogenesis of this group of disorders. As a result many previously unrecognised disorders have been charac terised. Some clinical syndromes, such as the limb girdle dystrophies, have become better defined. In many such instances the new genetic information has led to major advances in knowledge of the biology of cell structures, for example, the membrane structural and channel proteins. The clinical syndromes themselves, and their patho logical and electrophysiological characteristics, however, remain as important as ever, since they constitute the clinical problem itself and, indeed, the database from which all other concepts emerge. Knowledge of the pathogenesis, genetics, and molecular biology of neuromuscular disorders is essential both in developing and applying new therapies and preventive measures, and in formulating genetic and prognostic advice. However, this informa tion does not necessarily always define clinically useful syndromes. Myotonia, for example, is an electrophysiological finding in some syndromes in which it is un detectable by clinical examination, although the phenomenon itself was originally defined as a clinical entity. The limb girdle muscular dystrophy syndromes can be defined by severity, distribution of weakness, age of onset, sex distribution and other characteristics and many of these can be better understood by study of the under lying defect in cell structural proteins.
