| Popis: | In two studies on VDT work, activity of dominant forearm muscles was measured using surface electromyography. In the first study (n = 12), subjects used only a keyboard; whereas in the second study (n = 8), subjects used both keyboard and mouse. In both studies, analysis of results indicated that inter-subject differences in forearm muscle effort were significantly different (p < 0.05). In the first study, the minimum-to-maximum ratio for average extensor muscle activity was 1:3.7. In the second study, the minimum-to-maximum ratio was 1:2.2 for the flexor muscle activity and 1:3.7 for the extensor muscle activity. These results support the notion of differences in individual workstyles proposed by Feuerstein (1995). Individual typing styles play an important role play an important role in the stress on forearm muscles during VDT work and should be included in employee training protocols. |
