Mice and Other Input Devices
Various aspects of using mice and other input devices may increase your risk of
discomfort or injury. Observing the following recommendations may reduce
that risk.
• Try to keep your hand, wrist, and forearm in a neutral position while using
your mouse or other input device.
• If you use your thumb to rotate the ball on a trackball or spaceball, keep it
in a relaxed, natural shape, and maintain a neutral posture in your hand,
wrist, and forearm.
• Hold the mouse gently by draping your fingers over it. Keep your hand
relaxed and fingers loose. Do not grip the mouse tightly.
• It takes very little pressure or force from your fingers to activate the buttons
or scroll wheel on your mouse, scrolling mouse, trackball, or other input
device. Using too much force can place unnecessary stress on the tendons
and muscles in your hands, wrists, and forearms.
• If you are using a scrolling mouse, be sure to keep your fingers and hand in
a relaxed, neutral position when activating the scroll wheel. Also, this type
of mouse features software that can minimize the number of mouse
movements or button clicks.
• When using a mouse, trackball, or other input device, position it as close to
the keyboard as possible, and keep it at the same level as you do not have to
stretch while using it.
• Use a good quality mouse pad to enable the mouse to work most effectively
and reduce unnecessary hand and wrist movements.
• Be sure to keep your mouse and trackball clean. Regular removal of
accumulated dust and dirt helps ensure proper tracking and reduces
unnecessary hand and wrist motions.
