Musculo-skeleton injuries, which include tendinitis, carpal tunnel syndrome, chronic neck and back pain, and other Repetitive Strain Injuries (RSI), are the leading causes of disability in working-age people in North America. This paper highlights studies indicating that computer users are especially susceptible to these injuries; therefore, the keyboard techniques, computer practices, and workstation routines established in the early years are key to preventing injuries throughout life. The paper stresses the importance of the role of teachers and parents in the prevention and identification of RSI. Attention is given to carpal tunnel syndrome, eye strain, and neck and back pain. Three bad habits are identified with suggestions as to how they may be prevented. (Author/LPP)
