In contrast to intracellular recording in animal experiments, clinical electrodiagnostic procedures analyze extracellular potentials by surface or needle electrodes. Here the interstitial tissues act as a volume conductor, where the position of the recording electrode relative to the generator source dictates the size and waveform of the recorded potentials.Electromyographers analyze both the visual image of the waveform displayed on the screen and the auditory characteristics of the signals heard through a loudspeaker. The kind of information desired and the type of activities under study determine the optimal amplifier settings. This chapter deals with practical aspects of instrumentation, deferring a detailed discussion of electronics to Appendix 2.
