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 basicprinciples, 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 multiregionaldisorders 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 afloating text box that tracks the findings for each case. Cases begin with the clinical features, which dictate the initial EDXstudies performed. The results of those studies drive the next round of testing, which continues until the abnormality has beenlocalized and characterized and a diagnosis is made. In this manner, the dynamic nature of electrodiagnostic testing and processof 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 characterizationare extensively covered, including calculations of lesion severity for demyelinating conduction block and axon loss lesions andcalculations of various types of motor unit action potential recruitment frequencies. The book features a large number of anatomicaldrawings, charts, and EDX images in order to illustrate the skills of lesion localization and characterization comprehensively. Byconveying the 'cognitive approach' to EDX medicine, EMG Lesion Localization and Characterization merges clinical knowledgewith real-life cases to better instruct residents, fellows, technicians, and neuromuscular providers in the field of electrodiagnosticmedicine.
