| emg vs nerve conduction study: ANATOMICAL GUIDE FOR THE ELECTROMYOGRAPHER Perotto, Aldo O., 2011-08-01 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. |

| emg vs nerve conduction study: EMG Lesion Localization and Characterization Mark A. Ferrante, MD, Bryan Tsao, MD, 2019-09-28 EMG Lesion Localization and Characterization: A Case Studies Approach takes a unique approach to electrodiagnostic (EDX) medicine, using case studies and exercises to teach clinical reasoning and build technical skills. The first section presents basic principles, reviewing pertinent nerve and muscle anatomy, physiology, and pathophysiology along with study techniques, measurements, and pitfalls. The second section emphasizes how to most effectively utilize the book’s featured case studies, followed by 60 cases covering the range of disorders encountered in the EMG lab and organized by regional and multiregional disorders of the upper and lower extremities, brachial plexopathies, generalized disorders, and challenging cases. Through the EDX case studies, lesion localization and characterization are demonstrated and discussed step-by-step using a floating text box that tracks the findings for each case. Cases begin with the clinical features, which dictate the initial EDX studies performed. The results of those studies drive the next round of testing, which continues until the abnormality has been localized and characterized and a diagnosis is made. In this manner, the dynamic nature of electrodiagnostic testing and process of sequential study analysis is reinforced, just as it would be in the EMG laboratory. Authored by two leading experts in neurology and electrodiagnostic medicine, all aspects of lesion localization and characterization are extensively covered, including calculations of lesion severity for demyelinating conduction block and axon loss lesions and calculations of various types of motor unit action potential recruitment frequencies. The book features a large number of anatomical drawings, charts, and EDX images in order to illustrate the skills of lesion localization and characterization comprehensively. By conveying the “cognitive approach” to EDX medicine, EMG Lesion Localization and Characterization merges clinical knowledge with real-life cases to better instruct residents, fellows, technicians, and neuromuscular providers in the field of electrodiagnostic medicine. Key Features: Includes 60 cases covering all major neuromuscular disorders Presents basic and advanced anatomic, physiologic, pathophysiologic, and temporal principles and concepts pertinent to EDX medicine EDX studies are evaluated as they are collected, providing insight into the principles underlying electrodiagnostic medicine Through sequential step-by-step analysis of findings, the decision-making process required in the EMG laboratory is simulated Purchase includes access to the ebook for use on most mobile devices or computers |

| emg vs nerve conduction study: Cerebrovascular Ultrasound Michael G. Hennerici, Michael Hennerici, Stephen P. Meairs, 2001-10-25 Ultrasound provides a unique diagnostic perspective in cerebrovascular disorders, with extremely high temporal resolution and excellent spatial display of extracranial arteries, brain structures and cerebral vessels. This comprehensive text covers the fundamentals of ultrasound physics, new technology, and clinical applications in all ages. It provides a firm grounding in hemodynamics and describes computational models for study of the cerebral circulation. Extracranial applications in assessing the carotid and vertebral arteries are discussed in detail, as are intracranial Doppler applications in stroke, subarachnoid hemorrhage, arteriovenous malformations, interventional and surgical procedures, and the detection and monitoring of cerebral microembolism. These and other topics, both clinical and technical, are presented by leading authorities in the field, with extensive illustrations, and tables are included for the standardized classification of cerebrovascular diseases based on international consensus conferences. For clinicians and clinical neuroscientists this is the definitive reference text in cerebrovascular ultrasound. |
