Book Description
In the second century, Galen recognized that nerve and muscle were functionally inseparable since contraction of muscle occurred only if the nerves supplying that muscle were intact. He therefore concluded that the shortening of a muscle was controlled by the central nervous sytem while the extension of a muscle could occur in the absence of innervation. Nerves, he thought, were the means of transport for animal spirits to the muscles; the way in which animal spirits may bring about contraction dominated the study of muscle physiology from that time until the historical discovery of Galvani that muscle could be stimulated electrically and that nerve and muscle were themselves a source of electrical energy. It is now well known that nerves conduct electrically and that transmission from nerve to striated muscle is mediated by the chemical which is liberated from nerve terminals onto the muscle membrane. In vertebrates this chemical is acetylcholine (ACh). Thus the concept of spirits that are released from nerves and control muscle contraction directly, is no longer tenable. Nevertheless the concept of 'substances' transported down nerv~s which directly control many aspects of muscle has not been abandoned, and has in fact been frequently reinvoked to account for the long-term regula tion of many characteristics of muscle (see review by Gutmann, 1976) and for the maintenance of its structural integrity.

Book Description
In many cases of neuromuscular disorders the physician is faced with a complete lack of therapeutic approaches. This helplessness places the doctor in a position of conflict between his desire to help and his awareness that there is no treatment. In this situation it is tempting to indiscriminately use any procedure that avoids an admission of medical helplessness while satisfying the patient's demand for treatment. Electrical interventions are often used to avoid this situation. Due to the random use of therapeutic approaches it is not known what really happens. Presumptions and biased empirical observations have led to the exten sive use of different forms of electrical stimulation regimes in neuromuscular diseases. Due to this unsatisfactory situation it is necessary to know more about appropriate methods that are being used in particular disorders. The search for a better understanding of nerve-muscle interaction has shown that certain activity patterns can influence muscle. These experi mental results provide a rational basis for a possible therapeutic use of electrical stimulation of nerve and muscle. Previously most research has been conducted in normal tissue, and little is known regarding the re sponses of diseased muscle. In an interdisciplinary approach to this, it is our intention to present the current knowledge about basic principles of electrical stimulation in normal muscle. Before electrical stimulation can be accepted as a therapeutic tool, we felt it necessary to summarize the effects of activity in normal and diseased muscle and nerve.

Book Description
This third edition of Nerve and Muscle Excitation is intended as a text or general reference for students or researchers in neuroscience, biology, biomedical engineering, biophysics, physiology, medicine, neurology, neuroengineering or ancillary fields. It takes the approach of relating observed behaviours of excitable nerve and muscle membranes to the theoretical models currently in use by research workers in each area. Some familiarity, although not extensive knowledge, is assumed with calculus, electrical theory and chemistry; models in the text are derived from basic principles.

Book Description
Intended for clinicians who perform electrodiagnostic procedures as an extension of their clinical examination, and for neurologists and physiatrists who are interested in neuromuscular disorders and noninvasive electrodiagnostic methods, particularly those practicing electromyography (EMG) this book provides a comprehensive review of most peripheral nerve and muscle diseases, including specific techniques and locations for performing each test.
