If you're still typing from the top of your desk, you could be causing
yourself a great deal of pain and stress.
The major complaints
with keyboarding today are back pain, shoulder and neck pain and headaches.
A large percentage of these complaints can be alleviated through good
posture and the proper positioning of the keyboard.
Here's a quick check
to do right now; see how you fair.
being seated normally,
are your knees bent at 80-110° with your feet flat on the floor?
are you sitting
upright?
are your arms bent
at 80-110° at the elbow while typing?
are your upper
arms from your shoulder to your elbow vertical and naturally hanging close
to your body (any slight forward reaching of the arms increases the stress
to the back {trapezius} muscles greatly)?
If you answered "NO"
to any of these, then you should seriously reconsider your work environment
and find ways to create a more efficient and ergonomically correct area
starting with a Keyboard Arm.
