What Good Is EMG to the Patient and Practitioner?
Publication History
Publication Date:

ABSTRACT
Electromyography (EMG) and nerve conduction studies (NCS) are not only tests to be performed in isolation and reported without consideration of the clinical context, but rather form part of what has been referred to as the electrodiagnostic consultation. Using all of the pertinent information available to the electromyographer performing the test, the electrodiagnostic consultation strives toward the goal of helping the patient and the referring physician to establish a correct diagnosis. Although not without limitations, EMG as an extension of the clinical history and physical examination can be a powerful and sensitive diagnostic tool. Like any tool, however, the final result depends on the skill and expertise with which it is wielded.
