Electromyography: its use and misuse in peripheral nerve injuries.
Normal electromyograms and nerve conduction velocities have been briefly presented. Some of the factors that affect the outcome of the results of EMG and NCV testing have been enumerated. Although the approach of this article is negativistic, electrodiagnosis is a valuable tool to aid the clinician in many situations. Because of the many variables, careful interpretation of the results is essential, whether those results are positive or negative. The most important variable, the one upon which all the other variables rise or fall, is the knowledge and skill of the electromyographer performing the study. Choose carefully.
