Getting Started
Keyboard comfort
When using the computer, sit comfortably. Proper seating is one of
the primary factors in reducing work strain.
Position your chair so that the keyboard is at or slightly below
the level of your elbow. You should be able to type
comfortably with your shoulders relaxed.
Your knees should be slightly higher than your hips. If
necessary, use a foot rest to raise the level of your knees and
ease the pressure on the back of your thighs.
Adjust the back of your chair so that it supports the lower
curve of your spine. If necessary, use a cushion to provide
extra back support.
Sit with your back straight so that your knees, hips and elbows
approximately form 90-degrees angles when you work. Do
not slump forward or lean back too far.

Using your arms and wrists

Keep your wrists straight while typing. If necessary, adjust the
keyboard and chair height to keep wrists straight.
Avoid resting on your wrists while typing.
Use a light touch on the keys and mouse.
Avoid bending, arching, or twisting your wrists. Keep them in
a relaxed, neutral position while typing.
Exercise your hands, wrists and arms several times during the
day to improve circulation.
Regular attention to your work habits can make your time at the
computer more productive.
