Electrodiagnostic studies play an important role in the evaluation of patients
suspected of having a myopathic disorder. They are used to exclude alternative
diagnoses, confirm the presence of muscle disease, narrow down the differential,
and identify an appropriate biopsy site. The most informative part of the
electrodiagnostic study is needle electromyography. This allows for the analysis
of spontaneous activity and motor unit action potential morphology and
recruitment patterns. This article proposes a practical electrodiagnostic
approach and describes the electrophysiologic patterns of the most commonly
encountered myopathies.
