SUMMARY

Comparative cross-sectional study among 57

telephonist and 35 clerical staffs was conducted from

2008 to 2009. There was a statistically significant

decrease in some EEG indicators before and after

their work shifts such as: Alpha wave amplitude from

45,78 ± 14,10 nV to 39,07 ± 14,93 jjV; Alpha wave

index from 47,54 ± 12,06% to 41,83 ± 9,48%. The

decrease of telephonist in Hanoi were statistically

significant much more than in other provinces. Our

findings showed a highly fatigue of telephonists

during the working time.
