“…The beneficial effect of the use of lower arm support seems to be well documented (1,2,5), although almost no documentation from the «secondary» studies exists. Non-neutral positions of the wrist seems also to be a well documented predictor of symptoms and signs of DULDs (1,2,5,19). This evidence is supported by several laboratory studies by for example Rempel et al (33).…”

“…The evidence for the effect of height of the keyboard is diverging. The «primary» studies point out that a low position is a predictor of DULDs (1,2,5), but the opposite is found in one of the «secondary» studies (19). In this case the latter seems to be the most plausible association.…”

“…Six studies (1-7), that were described in 7 papers, used physical examination or objective signs for the case definition and is below designated as «primary» studies. In the remaining fourteen studies (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21), constituting the «secondary» studies, only selfreported symptoms were used for the case definitions (see Table 1). The table shows the documented relationships between certain exposures and one or several of the investigated upper limb disorders.…”

“…increased risk for symptoms and signs of DULDs with lowering of the keyboard. One of the «secondary» studies (19) showed a significant effect of high positioned keyboard on symptoms of arm discomfort. Another study (11) (see Table 1, including footnote 4) only showed an increased risk for symptoms if the increased height was combined with low decision latitude and «better» supervisor relations.…”

A review is presented of epidemiological peer-reviewed publications that relate the mechanical exposure of the arm in work with visual display units (VDU) to musculoskeletal disorders of the upper limb. The twenty included studies were divided into those with (1-7) and without (8-21) use of physical examination in the definition of cases. The main conclusion of this review is the documentation of evidence for the VDU work per se, none or insufficient lower arm support and non-neutral positions of the wrist as predictors of distal upper limb disorders (DULDs). These findings are based solely on studies that use physical examination or objective signs to define the DULDs, and the conclusions are not changed after inclusion of studies based only on self-reported symptoms. When the last category of studies is included as documentation in the review, the amount of VDU work (and an exposuredose/effect relationship) will also be documented as predictors. The referred studies indicated that not only the VDU work per se, but also (and in particular) VDU work for more than 20 hours per week combined with limited opportunity for rest breaks and without lower arm support is a predictor of DULDs. Another conclusion is that critical reviews may benefit from use of both strict criteria and less strict criteria for inclusion of studies, to optimize the conclusions drawn from existing documentation.

Upper extremity musculoskeletal symptoms among female office workers: Associations with video display terminal use and occupational psychosocial stressors

1996

View full text Add to dashboard Cite

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 from 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. © 1996 Wiley‐Liss, Inc.

This study was designed to verify the risk factors for developing upper extremities musculoskeletal disorders (UEMD) among workers engaged in customer service tasks performed by telephone at a private banking corporation in São Paulo, Brazil. The monthly incidence of UEMD in hands and/or wrists in this group was studied retrospectively from January 1993 to June 1995. The statistical analysis was done by using multiple linear regression with the monthly incidence of UEMD considered as dependent variable in models controlled for age, seniority, mean daily regular worktime and overtime per operator, time pressure at work, rest/work schedule, management status, personnel training on postural and muscle stretching, and ergonomic hazards. The variables associated with UEMD were the following: time pressure at work (coefficient = 0.049; p = 0.008) and rest/work schedule (coefficient = −0.047; p = 0.02). The results indicate that working conditions are significantly associated with UEMD, and changes in the working schedule may decrease the incidence of this problem in workers assigned to tasks related to the interactive use of computer‐accessible databases during telephone contacts.
