Improper work habits, poor workstation ergonomics, and environment can lead to physiological dysregulation such as muscle soreness, fatigue, and injury (Grandjean, 1987). Some workers develop chronic neck and upper limb pain also known as repetitive strain injury. (RSI), cumulative trauma disorder (CTD) or overuse syndrome, from long hours of repetitive tasks at personal computer workstations. Workers with RSI suffer loss of productivity and income with increasing medical costs. RSI accounted for forty percent of workers compensation cases in 1990. Discomfort and injury can shape the way PC users feel about their job and computers.
