Main Point made in the knol
The concept of ergonomics is not only confined to the shop floor of an industry, it has also occupied its space in the office premises as Office Ergonomics. One part of Office Ergonomics is Visual Display Terminal (VDT) ergonomics. VDT comprises of computer and its workstation, which includes positioning of the computer, working posture at the computer as well as the workstation for computer, like computer table, chair, accessories and work environment etc (ISO, 1998). People whose occupations involve spending prolonged period of time at the computer workstation are subjected to stresses that may lead to painful, debilitating conditions (Saito, 1996; Swoboda, 1992). The resulting stress may cause higher levels of fatigue and tension during the day. Prolonged exposure to a non-ergonomic working environment may lead to the development of Cumulative Trauma disorders, or CTD’S (Saito, 1996; Laville, 1980). Cumulative Trauma disorders or CTD’S are a class of injuries that arise from putting excessive pressure on the body to perform over a period of time.
