Management involvement—a key element in preventing musculoskeletal problems in visual display unit users in Australia

Abstract

A control strategy preventing musculoskeletal symptoms, referred to as over-use syndrome, in visual display unit (VDU) operators in a large office complex has been developed. The results of a 3-year study of VDU operators reporting symptoms of overuse syndrome formed the basis for evaluating the strategy. The control strategy included education programmes for managers and operators, workstation assessment and refurbishing, work-load restrictions, health screening, treatment and rehabilitation. Investigation and comparison included workstation inspection, work-load analysis, physiological factors and time off work or on an alternative work programme. The population consisted of 45 VDU operators in the first year (group A), 40 in the second year (group B) and at time of writing 15 in the third year (group C). Several significant differences between groups A and B were noted. Preliminary analysis of group C data indicated a further reduction in incidence rates. Present indications are that the rate will be reduced by more than 50% on group B figures. The information gained from the case analysis has provided a solid basis on which to review and upgrade our control strategies. Successful aspects of the programme, and areas requiring review or a different approach, have been conveyed to management and operators at training and review sessions. The key element in prevention is ensuring that managers and operators work together to improve job design and work environment. This includes taking into account the interaction between physical and psychosocial factors.
