Anatomical Guide For The Electromyographer

This invaluable book for the electromyographer dispenses the latest techniques detailing methods of intramuscular electrode placement. The author examines the basic principles in electromyography (EMG) and includes updated information for the appendicular and axial muscles. It is divided into 14 sections organized by anatomical region: the muscles of the hand, forearm, arm, shoulder girdle, foot, leg, thigh, pelvis, hip joint, perineal region, paraspinal region, abdominal wall, the intercostals and diaphragm regions, along with the muscles innervated by cranial nerves. This information includes the innervations and attachments of each muscle, how to position the patient for examination, the appropriate site for insertion of the electrode, the depth of insertion for the electrode, and the action that the patient should perform to activate the muscle. The descriptions of the techniques used for rarely examined muscles are sufficient for a clinician to have the confidence needed to perform the procedure. Common errors in electrode placement and clinically relevant comments are illustrated and discussed, including cross-sectional illustrations on the appendicular muscles. A particularly useful inclusion is “Pitfalls” that describes which muscle the electrode will record if the needle is placed too deep, not deep enough, or not at the location described. The text contains a useful appendix, providing dermatomes of the limb and trunk, cutaneous innervations of the head, and excellent illustrations of both the brachial plexus and the lumbo-sacral-coccygeal plexus. The appendix also contains a useful table listing all muscles that are presented in the text with innervations from the peripheral nerve to the mixed spinal nerve root. Well organized, clearly and concisely written, this book remains a learning tool and excellent reference for electromyographers and for healthcare practitioners who are expanding their practice skills to include diagnostic EMG, as well as for graduate students who use EMG as part of their research.

This fourth edition is a dynamic presentation of the latest writings regarding the techniques for approaching selected muscles and continues to detail methods of intramuscular electrode placement for the hand, forearm, arm, shoulder girdle, foot, leg, thigh, pelvis, and hip joint. A brief description and diagram are presented for each muscle. Each muscle is also covered with respect to segmental or peripheral innervation, origin, and insertion; position of patient or limb; point of electrode insertion; test maneuver to insure proper location of electrodes; and possible sources of error. A cros.

This manual is a practical, illustrated how-to guide to the proper techniques and electrode placements for common nerve conduction studies. The first section describes each nerve conduction study, including placement of electrodes, typical electromyography equipment settings, normal values, and pearls and pitfalls. The second section provides detailed coverage of surface anatomy for needle electromyography and shows where to place the needles for each muscle. More than 200 clear photographs demonstrate correct placement of needle electrodes. Chapters in each section follow a consistent sequence and are written in outline format to help readers find information quickly.

Beautifully and lavishly illustrated, Atlas of Nerve Conduction Studies and Electromyography demystifies the major conditions affecting peripheral nerves and provides electrodiagnostic strategies for confirming suspected lesions of the peripheral nervous system. Building on the success of the landmark Atlas of Electromyography, this new text is divided into sections based on the major peripheral nerves. It contains detailed illustrations of each nerve along with a discussion of its anatomy, followed by a thorough outline of the clinical conditions and entrapment syndromes that affect the nerve, including a list of the etiologies, clinical features, and electrodiagnostic strategies used for each syndrome. Routine and special motor and sensory nerve conduction studies are shown in an anatomical illustration. In addition, each muscle supplied by the peripheral nerve is illustrated showing the root, plexus, and peripheral nerve supply to the muscle and is accompanied by a corresponding human photograph. Written text provides information about the nerve conduction studies, muscle origin, tendon insertion, voluntary activation maneuver, and the site of optimum needle insertion, which is identified in the figures by a black dot or a needle electrode. Atlas of Nerve Conduction Studies and Electromyography is the perfect anatomical guide for neurologists, specialists in physical medicine and rehabilitation, and electrodiagnostic medicine consultants, while also providing support for individuals in residency training programs, critical care medicine, neurological surgery, and family practice.

The Atlas of Electromyography is a visually alluring book which provides high quality anatomical illustrations of skeletal muscles that include nerve, plexus, and root supply; photographs of each muscle in healthy subjects to enable the practitioner to identify the optimum site of EMG needle insertion; clinical features of the major conditions affecting peripheral nerves; and electrodiagnostic strategies for confirming suspected lesions of the peripheral nervous system. The atlas is divided into sections on the major peripheral nerves. Each nerve is illustrated and its anatomy reviewed in the text. The authors provide a detailed outline of the clinical conditions and entrapment syndromes that affect the nerve, including a list of etiologies, clinical features, and electrodiagnostic strategies used for each symdrome. Each muscle supplied by the peripheral nerve is shown as an anatomical illustration with a corresponding human photograph. The text provides information about the muscle origin, tendon insertion, voluntary activation maneuver, and site of optimum needle insertion. The needle insertion point is identified in both the anatomical illustration and the corresponding photographs. This assures that pertinent bone, muscular, and soft tissue landmarks can be used to guide the electromyographer to a specific point on the skin. Potential pitfalls associated with the needle insertion are added, usually noting adjacent muscles or structures that may be mistakenly entered. Clinical correlates pertinent to the muscle being examined are also provided. The tlas of Electromyography serves as an anatomical guide for practitioners of electromyography and neurologists, as well as residents i neurology, physical medicine, and rehabilitation.
