RIGHT
Hold a straight, neutral
wrist position while
typing.
WRONG!
Don't angle your wrists;
this may cause
unnecessary strain.
TIP
Split Keyboards
If you find it difficult to type with a straight,
neutral wrist position, you may want to try
a split keyboard. Be aware, however, that
improper setup or posture while using a
split keyboard can increase bending in
your wrists. So if you try one, set it up
properly to align your forearms, wrists, and
hands.
AVOID!
Be sure not to rest your wrists on sharp
edges.
