Computer workstation adjustment: a novel process and large sample study.
The use of computers in the US workforce is expected to grow throughout the 1990s. Prolonged computer use, repetitive keying, awkward postures and psychosocial issues have been associated with injuries described as cumulative trauma disorders (CTDs). The incidence and reporting of occupationally induced CTDs has increased dramatically since 1980. Proper adjustment of individual computer workstations requires time and technical knowledge. An automated process for computer workstation adjustment was developed using linked-segment anthropometry. Over 3300 employees in a large industrial complex voluntarily participated in this programme by completing a computer workstation questionnaire. Significant relationships were demonstrated comparing both hours and years of computer use with symptoms. A followup questionnaire was completed by 531 programme participants. Ninety percent indicated an improved understanding of proper computer adjustment. Eighty percent of those making recommended adjustments indicated benefits in reduced symptoms and greater work efficiency.
