Cardinal Rules of EMG 1: Nerve Conduction Study and EMG are an Extension of Clinical Examination
Abstract
Electromyographers have to understand that the electrodiagnostic studies including nerve conduction study and electromyography are not just laboratory procedure. Before or during the electrodiagnostic studies, we have information and make a design for an effective study of the electromyography based on clinical and physical examinations. Electromyographers agree with that the electrodiagnostic study shows high sensitivity and low specificity in diagnosis of neuromuscular disorders. I purpose to emphasize an importance of electrodiagnostic study as an extension of clinical examination in evaluation and diagnosis of neuromuscular diseases or disorders. In addition, I d like to discuss a point of view of clinical and physical examination importance in electrodiagnosis using patient cases.
Key Words: Cardinal rule, EMG, Nerve conduction study, Electrodiagnosis
