Electrodiagnostic medicine (EDX) is a medical subspecialty of
neurology, clinical
neurophysiology, and
physical medicine and rehabilitation. Electrodiagnostic physicians apply neurophysiologic techniques, including
needle electromyography and
nerve conduction studies to
diagnose, evaluate, and treat patients with impairments of the neurologic,
neuromuscular, and/or muscular systems. The provision of a quality electrodiagnostic medical evaluation requires extensive scientific knowledge that includes
anatomy and
physiology of the
peripheral nerves and
muscles, the physics and biology of the electrical signals generated by muscle and nerve, the instrumentation used to process these signals, and techniques for clinical evaluation of diseases of the peripheral nerves and sensory pathways
