Succinct yet comprehensive, Aminoff's Diagnosis of Neuromuscular Disorders, 4th Edition, provides expert information and guidance on the clinical, electrodiagnostic, and imaging aspects of neuromuscular disorders. Fully updated, it reflects important advances in the field, including an improved understanding of the molecular and genetic basis of neuromuscular disease, an expanded use of next-generation genetic testing, refinements in electrodiagnosis, and the use of ultrasound imaging techniques to evaluate the peripheral nervous system. In-depth discussions of disease states, as well as the evidence supporting the use of electrodiagnostic and imaging techniques, moves this reference from simply answering the question “How?” to also answering “Why?”
