“…Previous literature has focused on weekly self-reported estimates of computer use whereas we examined estimates of computer use throughout the day, along with estimates of break frequency and length captured throughout the day [15][16][17][18][19][20][21].…”

“…The use of computers at work has increased substantially during the last decade, and several studies report augmented problems with increased computer usage (Blatter and Bongers, 2002;Fogleman and Lewis, 2002;Jensen, 2003;Wigaeus Tornqvist et al, 2001).…”

Work related musculoskeletal disorders (WMSDs) in the shoulder/neck area are a common and increasing problem among European computer workers, especially women. Long-term low-level workloads with low degree of muscle rest are a potential risk factor for developing WMSDs. The purpose of the present study of female computer users (age 45-65 years) in Denmark and Sweden was to investigate if subjects with self-reported neck/shoulder complaints (cases, N = 35) show less trapezius muscle relative rest time (RRT) than controls (N = 44) when performing standardised short-term computer work tasks in controlled laboratory conditions. Surface electromyography (EMG) signals were recorded bilaterally from the upper trapezius muscles during a type, edit, precision and colour word stress task. Besides RRT, 10th percentile RMS values were calculated. On the average, 15 of the cases and 18 of the controls showed analysable EMG files per task. For the colour word stress task, the results showed lower RRT values and higher 10th percentile RMS amplitude levels among cases compared to controls. No such signs could be found for the other tasks performed. The present results indicate an increased motor response to a psychological stressor among subjects with self-reported neck/shoulder complaints.

“…Musculoskeletal symptoms are widespread among computer users with a high incidence of symptoms, especially in the neck-shoulder region, and the costs and impact on quality of life due to these symptoms are considerable (1)(2)(3)(4). Occupational computer use has become increasingly common over the past few decades, in particular among office workers; and the widespread use of computers today, together with the high incidence of symptoms, demonstrates a potential for the prevention or alleviation of symptoms among, for example, office workers, through the use of targeted interventions.…”
