Wrists up! Nicholas is correct about keeping the wrists inline with the forearms. The carpel tunnel is where the tendons transfer from the arm into the hand. And if you perform a repetative task with your wrist in an awkward position, you are more inclined to cause inflammation of the tendons inside the carpel tunnel. Swollen tendons leads to pain, and pain leads to death. Yoda would be proud of me. Think about your piano lessons. Wrists up! Nicholas is correct about keeping the wrists inline with the forearms.

At home I use a wrist rest (I need to get one for work) because if I don't have something to support my wrists at keyboard level I'll rest them on the desk, which means my wrists will have to bend upward to reach the keyboard, which is bad. But the main thing I need to avoid is bending my wrists sideways -- for example, if I sit too close to the keyboard, my forearms come in at an angle and I have to curve my wrists outward to be on home position. If I sit back a little and center my body on the G and H keys, I don't have to do that and I'll experience less pain in the long run.

I have typed for many years (!) now in many positions and none of them have given me pain. I do have to say though the most common position for me is with my elbows and forearms resting on the work surface - rather than hanging free. So, from my wrist to elbow, I am completely supported - only the fingers do any real movement. I know that isn't supposed to be correct but it continues to work for me. So it makes me wonder - is a supported forearm really a better position than the "correct" position? has anyone done any research on it?
