In the United States, neurologists and physiatrists receive training in electrodiagnostic medicine (performing needle electromyography and NCSs) as part of residency training and in some cases acquire additional expertise during a fellowship in clinical neurophysiology, electrodiagnostic medicine, or neuromuscular medicine. Outside the US, clinical neurophysiologists learn needle EMG and NCS testing.
