Abstract
A Study has been conducted to compare the effectiveness between improvement of furniture design (ergonomic design) and physical exercise in reducing musculoskeletal stress of the VDT (Video Display Terminal) operators. As an objective measurement, electromyograms (EMG) were measured from the neck, the left and right trapezius, L2/L3 region of back, triceps, flexor carp radialis and extensor carpi ulnaris. Subiective questionnaires were also used. Each of the five subjects was tested for two days (8 hours/day) in two different work stations which are an ergonomically designed work station and a traditionally designed work station using non-ergonomic devices. It was found that the physical exercises could reduce musculoskeletal stress as effectively as the ergonomic design.
