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.

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 techniquesWith 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.

This book is an introductory text for those people who need to know more about the scientific principles behind the study of the causes of disease occurence. As most people spend a large part of their lives at work, and as some people may be at risk of being exposed to harmful substances at high levels, workers protection should have a high priority. Studies in the workplace can help to identify causes of occupational diseases, and the outcome of such investigations should be applied when the effects of protective action are evaluated. In searching for occupational causes of diseases, epidemiological principles should be used, even at the factory level. Applying strict logical principles to the collection of data concerning worker's experience with ill-health ensures that a useful insight is gained into the causes of disease, and that data are obtained in a format suitable for subsequent larger-scale studies.
