Book Description
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.

Book Description
The electrical activity of the muscles, as measured by means of electromyography (EMG), is a major expression of muscle contraction. This book aims at providing an updated overview of the recent developments in electromyography from diverse aspects and various applications in clinical and experimental research. It consists of ten chapters arranged in four sections. The first section deals with EMG signals from skeletal muscles and their significance in assessing biomechanical and physiologic function and in applications in neuro-musculo-skeletal rehabilitation. The second section addresses methodologies for the treatment of the signal itself: noise removal and pattern recognition for the activation of artificial limbs. The third section deals with utilizing the EMG signals for inferring on the mechanical action of the muscle, such as force, e.g., pinching force in humans or sucking pressure in the cibarial pump during feeding of the hematophagous hemiptera insect. The fourth and last section deals with the clinical role of electromyograms in studying the pelvic floor muscle function.

Book Description
Reflecting a modern approach to electromyography, this edition includes new chapters on normal and abnormal neurophysiology, electromyography in children, and unusual studies. There is an emphasis on new techniques, needle stimulation and recording, and the use of electromyography in prognosis and management. Computer applications are integrated into the text, and there are updated discussions of carpal tunnel syndrome, radiculopathy and entrapments - including prognosis.

Book Description
Experimental Myopathies and Muscular Dystrophy. A Study of the Formal Pathogenesis of Primary Myopathies as Exemplified in the Myopathy of 2,4-Dichlorophenoxyacetic Acid The histochemical types of muscle fibres are described and a report presented of the histological and histochemical altera tions in skeletal muscles (tibialis anterior, gastrocnemius and soleus muscles) of rats given intraperitoneal injections of the herbicide, 2,4-dichlorophenoxyacetic acid (2,4-0). The liver and myocardium of the experimental animals were also examined. In skeletal muscle, alterations occurring acutely within 1 to 1. 5 h after injection of a single dose of 300 mg/kg 2,4-0 could be distinguished from changes which developed subacutely in the course of treatment with repeated injections of one quarter to one half of the LDSO of the substance. In both con ditions white (type 2B/Am) muscle fibres were involved pre dilectively. The principal histochemical effect of acute intoxi cation observed was leakage of phosphorylase and glycogen from white muscle fibres, whereas some of the red fibres (type 2A/C) m showed an increase in primary glycogen and phosphorylase activ ity. These changes, which must be considered nonspecifi~, were established by use of a gelatin incubation technique. They occurred as typical findings in the middle and deep areas of the anterior tibial muscle. In other muscles or different layers of the same muscle, these changes varied considerably in degree. Thus the gastrocnemius and soleus muscles displayed only minor or no alterations.

Book Description
This first of two volumes on EMG (Electromyography) covers a wide range of subjects, from Principles and Methods, Signal Processing, Diagnostics, Evoked Potentials, to EMG in combination with other technologies and New Frontiers in Research and Technology. The authors vary in their approach to their subjects, from reviews of the field, to experimental studies with exciting new findings. The authors review the literature related to the use of surface electromyography (SEMG) parameters for measuring muscle function and fatigue to the limitations of different analysis and processing techniques. The final section on new frontiers in research and technology describes new applications where electromyography is employed as a means for humans to control electromechanical systems, water surface electromyography, scanning electromyography, EMG measures in orthodontic appliances, and in the ophthalmological field. These original approaches to the use of EMG measurement provide a bridge to the second volume on clinical applications of EMG.
