Electrodiagnostic Medicine

Electrodiagnostic (EDX) medicine and EDX testing are an extension of the history and physical examination tailored to the clinical scenario. A wide range of tests are available, and it is incumbent on the electrodiagnostician to select those relevant to the clinical circumstances. The testing procedure may change as data are acquired and new findings interpreted. High-quality consultations are rendered by physicians with experience and technical competence coupled with an understanding of the peripheral nervous system. This chapter provides an overview of EDX tests, the extent of such testing for different clinical scenarios based on guidelines, and the types of abnormalities one can expect to find with different neuromuscular disorders.
