PY - 2016 T2 - Principles and Practice of Pain Medicine, 3e AB - Electrodiagnosis (EDx) can play a crucial role in identifying the underlying problem in a patient presenting with a pain disorder. In contrast with radiologic modalities such as magnetic resonance imaging (MRI), EDx provides unique functional information about the integrity of both the central and peripheral nervous systems. In addition to localizing the problem, EDx can give insight into chronicity, severity, and prognosis. For example, disc abnormalities of uncertain clinical significance are routinely found at multiple levels on MRI studies of the lumbar spine. EDx has the unique ability to determine whether one of these disc abnormalities is actually producing nerve damage. Moreover, such testing may also demonstrate abnormalities in patients with inflammatory lesions, where neuroimaging is often normal.
