Musculoskeletal Disorders
Use of game contr ollers, keyboards, mice, or other electronic input devices may be linked to serious injuries 
or disorde rs.
When playing video game s, as with many ac tivities , you may experi ence occasional discomfort in your 
hands, arms, shoulders, neck , or other par ts of your body. However, if you experie nce symptoms such 
as persistent or recur ring discomf ort, pain , throbbing , aching, tingling, numbnes s, burning se nsation, or 
stiffness, DO NOT IGNORE THESE WARNING SIG NS. PROMPTLY SEE A QUALIFIED HE ALTH PROFESSIONAL, 
even if symptoms occur when you are not playin g a video game. Symp toms such as thes e can be associated 
with painful and sometimes permanently disablin g injuries or disorders of the nerves, mu scles, tendons, 
blood vessels, and oth er parts of th e body. These mus culoskelet al disorders (MSDs) include c arpal tunnel 
syndrome, tendonitis, tenos ynovitis , vibration syndromes , and other conditions.
While researchers ar e not yet able to answer many questions about MSDs , there is gene ral agreem ent that 
many facto rs may be linked to their occurren ce, including medical and physical conditions, stress and how 
one copes with it, overall he alth, and how a person positions and uses their body durin g work and other 
activities (including playing a video game). Some studies suggest that the amount of tim e a person performs 
an activity may also be a factor.
Some guidelines that may help you work and play more comfort ably and possibly reduce your risk of 
experiencing an MSD can be fo und in the Healthy Gaming Guide (available at www.xbox.com). These 
guidelines address top ics such as:
● Positioning yourself to use comfort able, not awk ward, pos tures
● Keeping your hands, ngers, and other body part s relaxed
● Taking breaks
● Developing a healthy lifestyle
If you have questions about how your own lifest yle, activities, or medical or phys ical condition may be 
related to MSDs, see a quali ed health professional .
