This is a thorough discussion of eletrodiagnosis. It is written in simple, clear and concise German. There are six chapters and one appendix with thirty illustrations. The first chapter deals with the principles of galvanic and faradic currents. The second part discusses the methods of electrical testing with both currents and chronaxia. The third and fourth chapters list the results of the electrical tests. Normal and pathologic chronaxia values are given for all muscles as well as the variabilities in complete or partial lesions of nerves. The fifth part deals with the use of electricity in examining sensation and sense organs, as the optic, vestibular and acoustic nerves. The sixth chapter discusses testing of the vegetative nervous system and the spinal reflexes. The appendix includes a brief consideration of the impedance angle, psychogalvanic reflex, electrocardiography, electromyography and electro-encephalography. The book is highly recommended to all neurologists, physiologists and physical therapists.
