In the last twenty years electromyography and electro neurography have earned a secure position amongst methods of electrophysiological investigation; indeed, it is no longer possible to think of neurological diagnosis with out them. In particular, it is in the early recognition of peri pheral neuromuscular disorders that these techniques are so dependable and objective. The present text may be thought of as an introduction to method and to diagnostic application, and it should be of value to the physician both in hospital and in his practice. The authors have thought it best to omit discussion of basic scientific problems, which may be found in the neurophysiological literature. Munich, Spring 1974 A.

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. The book is divided into two major parts; the first an introduction to clinical electromyography and the second is separated into 27 case studies. The cases focus on localized disorders in the lower and upper extremities and end with a selection of generalized disorders. Each case begins with a detailed, tabulated, EMG study, followed by several questions, and a detailed analysis of the study, then takes into account patient history, the physical examination, EMG readings, treatment, and patient follow-up to sharpen the clinicians problem-solving skills.

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.
