Abstract

Objective: Ergonomically designed workstations have direct bearing on the comfort and safety of office computer users. Tremendous usage of computers in most offices of emerging economies have however, not seen accompanying applications of ergonomics in the design of computer workstations despite the numerous benefits. Injuries and discomforts therefore have higher propensity to occur since most offices formally designed for paperbased work now accommodate computer workstations, without corresponding redesigning. The study therefore sought to assess computer workstation designs in administrative offices at Kwame Nkrumah University of Science and Technology, with the aim of creating awareness of ergonomics and its application among administrative office computer users.
Method: A total of 150 office employees purposively sampled participated in this study. Respondents selected included secretaries, research assistants and data and account processors. This cross-sectional study consisted of a checklist (computer workstation components, visual complaints and ergonomics knowledge), work posture observations and measurements of workstation linear distances and monitor tilt angle. Descriptive statistics using Statistical Package for Social Sciences (SPSS) Version 20.0 was used for data analysis.
Results: Almost half (50%) of respondents had monitors facing windows without appropriate blinds, 42% with monitor tilt angle less than 10 degrees and majority (76%) observed monitors either at or above horizontal eye level. Most (70%) of the workers acknowledged not having knowledge of ergonomics whiles 100% noted that they did not have any ergonomic assessment of their workstations. Neck, back and shoulder pains were reported by 85% of respondents while 73% complained of eyestrain.
Conclusion: The study revealed lack of information and skills in ergonomics contributing to poor ergonomic conditions and consequent visual discomforts among computer users in the work place.
