Relevant case presentations are included to aid learning, and the authors also focus on the practical applications of the test results, including discussions of major neuromuscular diseases amenable to diagnosis via electromyography. Pediatric Electromyography: Concepts and Clinical Applications is aimed at residents, technologists and staff pediatric neurologists, as a practical guide and exam study guide.

Reflects on developments in noninvasive electromyography, and includes advances and applications in signal detection, processing and interpretation Addresses EMG imaging technology together with the issue of decomposition of surface EMG Includes advanced single and multi-channel techniques for information extraction from surface EMG signals Presents the analysis and information extraction of surface EMG at various scales, from motor units to the concept of muscle synergies.

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.

Invasive electromyography is a well-established diagnostic tool that has been used for decades by neurologists. Recently, new and alternative devices have increasingly become available that permit diagnosis without the use of needles. This developing area of science and the new tools have not, however, been sufficiently investigated in academic training. Consequently a gap exists between what science is making possible and the competence acquired during graduate studies. This handy volume has the aim of filling this gap by providing the information required by medical practitioners in rehabilitation, sports, and occupational health as well as by rehabilitation therapists, ergonomists, and sport coaches. The techniques that are presented and explained will help in monitoring and recording changes, evaluating the effectiveness of treatments and training, evaluating work stations, and preventing and documenting the evolution of occupational disorders of the neuromuscular system.

The technique of electromyography, used to study the electrical currents generated by muscle action, has become invaluable to researchers in the biological, medical, and behavioral sciences. With it, the scientist can study the role of muscles in producing and controlling limb movement, eating, breathing, posture, vocalizations, and the manipulation of objects. However, many electromyographic techniques were developed in the clinical study of humans and are inappropriate for use in research on other organisms--tadpoles, for example. This book, a complete and very practical hands-on guide to the theoretical and experimental requirements of electromyography, takes into account the needs of researchers across the sciences.

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 manual is a practical, illustrated how-to guide to the proper techniques and electrode placements for common nerve conduction studies. The first section describes each nerve conduction study, including placement of electrodes, typical electromyography equipment settings, normal values, and pearls and pitfalls. The second section provides detailed coverage of surface anatomy for needle electromyography and shows where to place the needles for each muscle. More than 200 clear photographs demonstrate correct placement of needle electrodes. Chapters in each section follow a consistent sequence and are written in outline format to help readers find information quickly.

Functional Electromyography: Provocative Maneuvers in Electrodiagnosis integrates electrophysiology further into the physical examination than ever before. It introduces the use of electrodiagnostic studies to quantify the neurological changes brought about by three provocative maneuvers commonly used in contemporary medicine. This widens the scope of electromyography while sharpening physicians’ diagnostic acuity. The book presents nerve conduction velocity (NCV) and H-reflex techniques to identify common conditions that are difficult to diagnose by any other means, often using the needle exam (EMG), MRI or musculoskeletal ultrasound to verify their clinical utility. Functional electromyography successfully diagnoses some cases of thoracic outlet syndrome, nearly all cases of piriformis syndrome, and offers a method for determining whether spinal stenosis or radiculopathy is the main pain generator when both are present in a single patient, even at the same level. This is particularly valuable because the standard conservative and surgical treatments for these two conditions are opposite, in spite of the identical symptom-set they produce. The book carefully describes each technique and persuasively documents their validity in statistical series and individual case presentations. It further guides the attentive electromyographer to adapt these methods to cases beyond those presented in its pages, suggesting a safe and scientific approach to other functional maneuvers of value to the electromyographer, and methods for validating one-time measures that may aid the electromyographer in clinical situations that are neither common nor easily analyzed. Hand drawn illustrations are included alongside text developed by experts in the field. An invaluable resource for physiatrists, neurologists, orthopedic surgeons, specialists in pain management and other providers, Functional Electromyography: Provocative Maneuvers in Electrodiagnosis represents a major contribution to the field of electrodiagnosis.

"Essentials of Electromyography "explains and explores the use of electrical recordings of muscle movements for students taking courses in EMG or any professional dealing with human movement.
