ABSTRACT The relationships between musculoskeletal symptoms and both video display terminal (VDT) use and occupational psychosocial stress were assessed among women office workers by self-administered questionnaires. Significantly increased odds ratios for neck or shoulder symptoms were observed for subjects who had ever used a VDT, had less job security, and had more stressful work during the 2 weeks prior to completion of the questionnaire. Significantly increased odds ratios for arm and hand symptoms were observed for subjects who had used a VDT for more than 6 years, reported a very crowded workplace, or reported very stressful work during the 2 weeks prior to completion of the questionnaire. Among current non-users, those who previously used VDTs were more likely to report upper extremity musculoskeletal symptoms than those who had never used VDTs. This suggests that individuals with symptoms may be more likely to reduce their VDT usage, distorting results of cross-sectional studies.

    • "With over 45,000,000 computers in US workplaces, concerns exist about an escalation in the incidence of computer-related WMSDs (Tittiranonda et al., 1999). Studies have revealed a variety of contributing factors to musculoskeletal discomfort including: increased job demands and more hours working at a computer (e.g., Bernard et al., 1994; Faucett and Rempel, 1994), increased levels of psychological stress (e.g., Bongers et al., 1993; Carayon and Smith, 2000; Marcus and Gerr, 1996; Faucett and Rempel, 1994), and a lack of specific ergonomic features in the workstations and office buildings (e.g., Nelson and Silverstein, 1998; Sauter et al., 1990).

    ABSTRACT: A large-scale field intervention study was undertaken to examine the effects of office ergonomics training coupled with a highly adjustable chair on office workers' knowledge and musculoskeletal risks. Office workers were assigned to one of three study groups: a group receiving the training and adjustable chair (n=96), a training-only group (n=63), and a control group (n=57). The office ergonomics training program was created using an instructional systems design model. A pre/post-training knowledge test was administered to all those who attended the training. Body postures and workstation set-ups were observed before and after the intervention. Perceived control over the physical work environment was higher for both intervention groups as compared to workers in the control group. A significant increase in overall ergonomic knowledge was observed for the intervention groups. Both intervention groups exhibited higher level behavioral translation and had lower musculoskeletal risk than the control group.

    • "If unsafe, these prolonged postures can affect the lower back, the upper limbs, and neck and place workers at risk for MSDs (Nelson & Silverstein, 1998; Sauter & Downloaded by [Western Michigan University] at 11:12 03 September 2012 Schleifer, 1991). Similarly, repetitive keyboard and mouse use places workers at risk of muscle, tendon, and nerve damage (Gerr, Marcus, & Monteilh, 2004; Marcus, 1996). Evidence supporting a causal link between highly repetitive work and neck and neck-shoulder MSDs is documented in a review of over 600 epidemiological studies by the National Institute for Occupational Safety and Health (National Institute for Occupational Safety and Health [NIOSH], 2000), and the National Academy of Sciences (NAS) (USDOL, 1998).

    ABSTRACT: The effects of workstation changes and a performance management (PM) package on seven typing postures were examined for seven office workers. Workstation adjustments were implemented first. Two participants increased five safe postures by 50% or more. The effects of a PM package on postures that did not improve by 50% were then examined using a multiple baseline design across participants. The PM package included information, feedback, and praise. Composite percent safe scores for postures targeted in the PM package increased for all seven participants, with increases ranging from 54% to 80%. Results suggest that it is beneficial to combine ergonomic design and performance management in office ergonomic programs. (Contains 5 tables and 2 figures.)

    • "The incidence of CTDs in computerized workstation environments is on the rise (Bammer , 1987; Bergqvist et al., 1995; Bernard et al., 1994), which is due, among other factors, to the maintenance of sustained postures, which a!ect the low back, the upper limb and neck (Sauter, 1991; Nelson and Silverstein, 1998). Repetitive keyboard and mouse use places workers at risk of muscle, tendon, and nerve damage (James et al., 1997; Marcus, 1996). Despite the provision of appropriate furniture and workstation setup, many workers complain of musculoskeletal pain. "

    ABSTRACT: Microbreaks are scheduled rest breaks taken to prevent the onset or progression of cumulative trauma disorders in the computerized workstation environment. The authors examined the benefit of microbreaks by investigating myoelectric signal (MES) behavior, perceived discomfort, and worker productivity while individuals performed their usual keying work. Participants were randomly assigned to one of three experimental groups. Each participant provided data from working sessions where they took no breaks, and from working sessions where they took breaks according to their group assignment: microbreaks at their own discretion (control), microbreaks at 20 min intervals, and microbreaks at 40 min intervals. Four main muscle areas were studied: the cervical extensors, the lumbar erector spinae, the upper trapezius/supraspinatus, and the wrist and finger extensors. The authors have previously shown that when computer workers remained seated at their workstation, the muscles performing sustained postural contractions displayed a cyclic trend in the mean frequency (MNF) of the MES (McLean et al., J. Electrophysiol. Kinesiol. 10 (1) (2000) 33). The data provided evidence (p < 0.05) that all microbreak protocols were associated with a higher frequency of MNF cycling at the wrist extensors, at the neck when microbreaks were taken by the control and 40 min protocol groups, and at the back when breaks were taken by the 20 and 40 min protocol groups. No significant change in the frequency of MNF cycling was noted at the shoulder. It was determined (p < 0.05) that microbreaks had a positive effect on reducing discomfort in all areas studied during computer terminal work, particularly when breaks were taken at 20 min intervals. Finally, microbreaks showed no evidence of a detrimental effect on worker productivity. The underlying cause of MNF cycling, and its relationship to the development of discomfort or cumulative trauma disorders remains to be determined.
