First of all, some basic information is given on the relatively few developments in the field of quantification of the EMG as compared with the EEG. Some of the most commonly used electromyographic techniques are described with the criteria for their use; their limitations are also mentioned. Nevertheless, they represent not only useful resources for documentation in hospitals or interpretation of neurophysiological mechanisms, but some of them are also successfully used by the authors to evaluate the effectiveness of pharmacologically active substances. Unfortunately, no fully automatic method could be considered here. One of the major problems is the standardization of suitable methods of analysis, in order to be able to express correctly the various results obtained. Finally, some data are demonstrated which have been obtained by interval analysis during the differential diagnosis of facial myokymia and the use of drugs pharmacologically effective in this type of activity. The authors estimate that there will in future be greater interest on the part of pharmaco-EEG scientists, so that the electroencephalographic profile of psychotropic drugs will be supplemented by electromyographic data; consequently we can expect that greater effort will be put into the standardization of methods of automatic analysis.
