 PhotosensitiveSeizures
A very small percentage of people may
experience a seizure when exposed to
certain visual images, including flashing
lights or patterns that may appear in
video games. Even people who have no
history of seizures or epilepsy may have
an undiagnosed condition that can cause
these "photosensitive epileptic seizures"
while watching video games.
These seizures may have a variety of
symptoms, including lightheadedness,
altered vision, eye or face twitching,
jerking or shaking of arms or legs,
disorientation, confusion, or momentary
loss of awareness. Seizures may also
cause loss of consciousness or
convulsions that can lead to injury from
falling down or striking nearby objects.
Immediately stop playing and consult a
doctor if you experience any of these
symptoms. Parents should watch for or
ask their children about the above
symptoms—children and teenagers are
more likely than adults to experience
these seizures. The risk of photosensitive
epileptic seizures may be reduced by
taking the following precautions:
• Sit farther from the TV screen.
• Use a smaller TV screen.
• Play in a well-lit room.
• Do not play when you are drowsy or
fatigued.
If you or any of your relatives have a
history of seizures or epilepsy, consult a
doctor before playing.
 musculoskeletalDisorders
Use 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
2
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 at www.xbox.com. These
guidelines address topics such as:
• Positioning yourself to use
comfortable, not awkward, postures.
• Keeping your hands, fingers, and
other body parts relaxed.
• Taking breaks.
• Developing a healthy lifestyle.
If you have questions about how your
own lifestyle, activities, or medical or
physical condition may be related to
MSDs, see a qualified health
professional.
