Definition
Electrodiagnosis is a neurophysiological study used to detect problems involving nerves or muscles.
Current Knowledge
Electrodiagnosis (EDX) as an extension of the neuromuscular/physical examination employs the anatomical principles of localization, searching for evidence of motor and sensory injury. It is most helpful in the evaluation of patients with problems of weakness, paresthesia, pain, or fatigue. Electrodiagnosis not only can support or confirm clinical diagnosis but suggest the severity or extent of the disorder. Electrodiagnosis may also help exclude other diagnosis and have an important prognostic role in guiding management. EMG of neuromuscular disease applies knowledge of basic physiological processes involved in impulse transmission in peripheral nerves, the motor unit, and muscles and changes produced in these processes by disease. Complications are minimal and include mild discomfort or...
