The main purpose of electromyography (EMG) instrumentation is to accurately record and display the nerve and muscle signals that are physiologically relevant. Understanding the electrophysiologic instrument's components and processing of recorded
biologic signals are important to avoid artifactual data collection leading to erroneous diagnostic conclusions. This paper approaches the basic components of the EMG machine and presents practical tips for its utilization in electrodiagnosis.
The
topics about basic electrical circuit, electrodes, filters, amplifiers, digital electronics, stimulator and interference are discussed in this paper at an introductory level. It will provide basic understanding about instrumentation and some
familiarity
to EMG instrument. The most important aspect to remember is that the skills necessary to practice accurated electrodiagnosis does not depend on the EMG instrument itself but the practitioner.
