VDT ergonomics: upper extremity assessment requires a holistic approach.
Repetitive strain injuries (RSI) of the hand and upper extremity have been linked to video display terminals (VDT). The incidence of RSI has increased with the proliferation of computer use in the workplace and at home. A holistic approach to dealing with upper extremity RSI begins with the seated position. Simple adjustments made here can correct much of the poor positioning of the shoulders, arms, and hands. The rest of the workstation can then be designed around the correctly seated VDT user. In addition to being instructed in appropriate seating and posture, the VDT user must also learn proper keyboard technique, work pacing and rotation, and exercises to stretch shortened muscles and strengthen overstretched muscles. A checklist to review the basic components of a VDT ergonomic analysis has been developed.
