      <subfield code="a">The reliability of normalized EMGrms (root mean square value of the electromyographic signal) measurements from musculus trapezius were evaluated in a field study. The reproducibility and stability of the methods as well as the reproducibility of the results for nine variables were examined. The variables were: static, median and peak values of the ADF and the total time and number of periods when the muscle's load was below 1,2 and 5% of MVC (maximum voluntary contraction)</subfield>
