Musculoskeletal DisordersUse of game controllers, keyboards, mice, or other electronic input devices may be linked to serious injuries or disorders.When playing video games, as with many activities, you may experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESSIONAL, even if symptoms occur when you are not playing a video game. Symptoms such as these can be associated with painful and sometimes permanently disabling injuries or disorders of the nerves, muscles, tendons, blood vessels, and other parts of the body. These musculoskeletal disorders (MSDs) include carpal tunnel syndrome, tendonitis, tenosynovitis, vibration syndromes, and other conditions.While researchers are not yet able to answer many questions about MSDs, there is general agreement that many factors may be linked to their occurrence, including medical and physical conditions, stress and how one copes with it, overall health, and how a person positions and uses their body during work and other activities (including playing a video game). Some studies suggest that the amount of time a person performs an activity may also be a factor.Some guidelines that may help you work and play more comfortably and possibly reduce your risk of experiencing an MSD can be found in the Healthy Gaming Guide (available at www.xbox.com). These guidelines address topics such as:● Positioning yourself to use comfortable, not awkward, postures● Keeping your hands, ingers, and other body parts relaxed● Taking breaks● Developing a healthy lifestyleIf you have questions about how your own lifestyle, activities, or medical or physical condition may be related to MSDs, see a qualiied health professional.Regulatory InformationTested to comply with FCC (U.S. Federal Communications Commission) Standards.
