Shoulders And Elbows - HP Compaq Presario,Presario 1700 Reference Manual

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

Shoulders and Elbows

Adjust your chair height or keyboard height so that your shoulders are relaxed and
your elbows hang comfortably at your sides. Adjust your keyboard slope so that
your wrists are straight.
Checking Elbow Height
Position your elbows in a zone that is near the height of your keyboard's home row
(the row that includes the letters G and H). This position allows you to relax your
shoulders. If you have long upper arms, you may find you need to position your
elbows a bit below the height of home row in order to provide enough space under
the work surface for your knees and legs.
*
RELAX: Remember to relax, particularly in areas where muscle tension often builds,
such as your shoulders.
WRONG!
Don't angle your wrists; this may cause
unnecessary strain.
RIGHT!
Turn your chair to the side to help determine if
your elbow height is near the height of your
keyboard's home row.
