This cross-sectional study examines the relationship between ergonomic risk factors and upper extremity
musculoskeletal symptoms (UEMSS) in VDT workers at a Hi-Tech company, while taking into account individual
and work organizational factors, and stress. The study population of 84 workers (92% response rate) is comprised of
computer programmers, managers, administrators, and marketing specialists. Data on UEMSS, individual and
organizational factors, and stress were derived from a questionnaire, while ergonomic data were collected through two
direct observations via the rapid upper limb assessment (RULA) method. Results of the RULA observations indicate
excessive postural loading with no employee in acceptable postures (all scoresX3). Hand/wrist/finger symptoms were
related to the RULA arm/wrist score (in a logistic regression model) as well as working with a VDT between 7.1 and 9h
a day, and working in Hi-Tech companies for more than 2 years. Neck/shoulder symptoms were related to: gender
(female), working410h a day, working at the Hi-Tech company for more than 2 years, and being uncomfortable at the
workstation. The results underline the need for implementing an intervention program focusing on arm/wrist posture,
and for taking into account the special needs of subgroups: gender, working 10h a day, working 7.1–9h a day with a
VDT, and employees experiencing discomfort at workstations.
Relevance to industry: Upper extremity musculoskeletal disorders and ergonomic research have not focused enough
on the Hi-Tech industry. Even with the .com crash, this industry remains a major force in the world economy. VDT
work in the Hi-Tech industry has unique risk factors, which might lead to specific needs for intervention
