Title Musculoskeletal, visual and psychosocial stress in VDU operators before and after multidisciplinary ergonomic interventions
Bibliographic information Oct. 1998, Vol.29, No.5, p.335-354. Illus. 77 ref.
Abstract Three serial interventions were carried out on two groups of VDU workers: a new lighting system, new workstations (providing support for the forearm and hand) and an optometric examination and corrections if needed. Both groups reported significant improvement in lighting conditions and visual conditions and significantly reduced visual discomfort and glare. Significant reduction of headache was found in one of the groups. Optometric corrections reduced the visual discomfort in both groups. Before the workstation changes there were no significant differences between the groups regarding shoulder pain and static trapezius electromyography load. Two years after the intervention, a significant reduction of shoulder pain was reported in the two groups in parallel with a significant reduction in static trapezius load. Pain in the forearm and hand showed no significant changes during the study period. However, there appeared to be a relationship between pain in the forearm and hand and the time the operator used the mouse. Topics: artificial lighting; backache; comfort assessment; comparative study; CRT display terminals; electromyography; illumination levels; luminance; migraine; neuropsychic stress; shoulder; stress factors; upper extremity disorders; visual comfort; workplace design.
