Clinical Applications In Surface Electromyography

This comprehensive book covers each of the clinical applications of surface EMG, surface EMG evaluation & feedback, candidate selection, kinesiologic & psychophysiologic, patient training & numerous case examples. The book also provides a procedural approach to using surface EMG in clinical practice to either document the therapeutic process or as an aid in treatment of the condition.

Surface electromyography (sEMG) represents the electrical activity generated in the muscle fibres in response to the activation provided by the innervation of motor neurons. An sEMG device amplifies, decomposes, and filters the electrical signals that occur during muscle contraction. In this book, Chapter One provides an overview on two decades of sEMG research in swimming and water polo conducted by the Faculty of Sport and Porto Biomechanics Laboratory, both from the University of Porto, Portugal. Chapter Two reviews the clinical use of sEMG in the fields of kinesiology and rehabilitation. Chapter Three examines the use of sEMG signals as a natural control interface. Chapter Four explains the use of SEMG to examine changes in muscular activation that are provoked by orthopedic insoles.

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.

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.

This second of two volumes on EMG (Electromyography) covers a wide range of clinical applications, as a complement to the methods discussed in volume 1. Topics range from gait and vibration analysis, through posture and falls prevention, to biofeedback in the treatment of neurologic swallowing impairment. The volume includes sections on back care, sports and performance medicine, gynecology/urology and orofacial function. Authors describe the procedures for their experimental studies with detailed and clear illustrations and references to the literature. The limitations of SEMG measures and methods for careful analysis are discussed. This broad compilation of articles discussing the use of EMG in both clinical and research applications demonstrates the utility of the method as a tool in a wide variety of disciplines and clinical fields.

Surface EMG is a popular tool used by physical therapists, occupational therapists, and chiropractors in both assessing and treating a wide range of neuromusculoskeletal disorders. This book provides the basics of surface EMG. It addresses such questions as what is EMG? Why use surface EMG? When and how is it used? Featuring a complete Atlas for Electrode Placement, the book introduces electrode placement strategies for various disorders, understanding and interpreting the surface EMG signal, and basic formulations for treatment strategies. Each chapter includes clinical examples to orient the practitioner to surface EMG's potential use.

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.
