| Abstract |
Surface electromyogram recordings from the descending part of the trapezius muscle and discomfort ratings were assessed for 6 female VDT word processor operators. Each operator was studied during 3 work periods of 3 to 5h on different days. During one of the work periods, 15-sec. pauses were introduced every 6th minute. A static muscular load of 3.2% and 3.0% of the maximal voluntary contraction was found on the right and left side, respectively. The median and peak muscular loads during work were low. There was a significant negative correlation between pauses and static load on the right upper trapezius muscle. The rating of perceived discomfort was less after the work periods with short pauses than after the work periods without. |
