Reporting the results of needle EMG and nerve conduction studies: an educational report.

Needle electromyography (EMG) and nerve conduction studies (NCSs) performed by a physician (MD or DO) with the appropriate education, training, and experience are used to evaluate patients with neuromuscular (NM) diseases and diagnose the presence, distribution, and severity of nerve, NM junction, and muscle pathology.1 After needle EMG and NCSs studies are completed, it is necessary to prepare a written report of the test results. This report serves as a communication tool to the referring physician and documents the results and conclusions of the electrodiagnostic (EDX) evaluation. This educational document created by the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) addresses the following two key clinical questions.
