About Repetitive Strain Injury Because your comfort and safety are our primary concern, we strongly recommend that you use HP computing equipment in accordance with established ergonomic principles and recommendations. Scientific literature suggests that there may be a relationship between injury to soft tissuesespecially in the hands and armsand prolonged improper use of keyboards or other equipment requiring repeated motions of the hands and forearms. This literature also suggests that there are many other risk factors that may increase the chance of such injury, commonly called Repetitive Strain Injury. Repetitive Strain Injury (RSIalso known as cumulative trauma disorder or repetitive motion injury) is a type of injury where soft tissues in the body, such as muscles, nerves, or tendons, become irritated or inflamed. RSI has been a reported problem for those who perform repetitive tasks such as assembly line work, meatpacking, sewing, playing musical instruments, and computer work. RSI also has been observed in those who frequently engage in activities such as carpentry, knitting, housework, gardening, tennis, windsurfing and lifting children. The specific causes of RSI have not been established. Nevertheless, the incidence of RSI has been associated with a variety of risk factors, including: Too many uninterrupted repetitions of an activity or motion. Performing an activity in an awkward or unnatural posture. Maintaining static posture for prolonged periods. Failing to take frequent short breaks. Other environmental and psychosocial factors. In addition, there have been reports associating the occurrence of RSI with the use of computer keyboards, mice, and other input devices. Also, certain medical conditions, such as rheumatoid arthritis, obesity and diabetes, may predispose some people to this type of injury. 3
