Title Effects of ergonomic intervention in work with video display units
Bibliographic information Feb. 2002, Vol.28, No.1, p.18-24. Illus. 22 ref.
Abstract This study evaluated the effect of an intensive ergonomic approach and education on workstation changes and musculoskeletal disorders among workers who used a video display unit (VDU). The 124 subjects were allocated into three groups (intensive ergonomics, ergonomic education, reference) using stratified random sampling. The evaluation involved questionnaires, a diary of discomfort, measurements of workload and an ergonomic rating of the workstations. The intensive and training groups showed less musculoskeletal discomfort than the reference group after two months of follow-up. Positive effects were seen primarily for the shoulder, neck and upper back areas. Both the intensive ergonomics approach and education in ergonomics help reduce discomfort in VDU work. In attempts to improve the physical ergonomics of VDU workstations, the best result will be achieved with cooperative planning in which both workers and practitioners are actively involved.
