This is the third in a series of posts regarding [tag]computer headaches[/tag], causes and solutions.

3. Monitor is off center or to the side, resulting in prolonged and repetitive neck and trunk rotation. It requires constant contraction of neck muscles to hold your head looking at the monitor to the side. This off center position causes this problem even if it is only slightly off center.

RISKS

Twisting of the spine in the neck causes excessive compression of the facet joints on one side, and stretching and tearing of muscles and ligaments on the other side. This risks facet joint injury, spinal instability, and a tendency to spinal degeneration, an arthritic condition too often found in office based workers. There is also excessive pinching of the outer layers of the lumber discs, contributing to the risk of ruptured or herniated discs. Finally, there is significant muscle work to maintain a rotated posture, with resultant fatigue, tension and headaches.

SOLUTION

A] Move monitor by rearranging desktop so operator, keyboard, and monitor are lined up.
B] Leave the monitor where it is and install a keyboard tray so the operator can face the monitor. These hold the keyboard and mouse and attach under the desk and pull out, raise or lower, rotate sideways, and tilt so you can easily work in your most relaxed posture.
C] When the monitor is at the corner of an L-shaped desk, install a corner extension to hold the keyboard.
