The explosion of computer technology over the past two decades has resulted in computer related Repetitive Strain Injuries (RSI). Prolonged and repetitive work or play at the computer workstation can create neck, shoulder, arm, and hand discomfort and be the cause of work related injuries. Improper posture and improper ergonomics at the computer workstation can exaggerate the problems. Implementing simple ergonomic guidelines can help the computer user avoid injuries
