Electromyography and Evoked Potentials

Over the last decades the developments and applications of electromyo- graphic and electroneurographic methods have been of great value in giv- ing us insights into the functions of various neuronal systems. More re- cently, considerable advances in new technologies, e.g. computerization and microtechniques, as well as a remarkable increase of interest in the functions of the central nervous system, especially in motor control, can be recognized. The tremendous advances in the development of electromyography, electroneurography and evoked potential recording as well as in record- ing of single motor units and of single nerve fibres raised the question from a clinical-physiological and physiological point of view as to which methods are relevant for clinical diagnosis and which technological devel- opments can provide us with better insight into the functions of the ner- vous system? This book which is based on a well balanced distribution of clinical neurophysiological and physiological contributions presents a great variety of important and interesting topics.We are grateful to the International Federation of Societies for Elec- troencephalography and Clinical Neurophysiology, in particular to the Chairman of the EMG Commission, Prof. J.
