Office ergonomics

Have you ever wonder the posture we sit in the office can cause problem on our shoulder, wrist and arm?? Yes, it is but not many people experience it. I had this problem recently and it is totally no fun at all.

I experienced shoulder and wrist pain since last week and I must say, it is very uncomfortable and affect my mood. I experienced since last Thursday or Friday cant really remember which day. And I thought it was just normal pain, because I had this shoulder pain problem all the while, especially when I finished intensive exercise. The problem didn’t stop and getting worst this week and I had realized it must be my sitting posture. The pain starts from my wrist and extend to my shoulder. I feel the pain from wrist to arm when ever I move mouse, or simply place a click or scroll button. Wow…. It is totally NO FUN AT ALL! Trust me.

I then stretched my wrist by bend it to 90 degrees as often as I can. Also I changed my sitting posture by sit up right and my hands and shoulder are in the 90 degrees position. After stretching and changing sitting position, situation turned better now. Pain is still there but I feel a lot better now.

I got this from Computer Workstation Ergonomics

MOUSE, TRACKBALL, OR OTHER INPUT DEVICE
The mouse is present in virtually every office environment. Handed versions of mouses are designed specifically to the contours of either the right or left hand.

Placing the mouse, trackball, or other input device too far away, too low, or too much on one side can cause shoulder, wrist, elbow, and forearm discomfort. Placing the input device directly in your immediate reach zone offers natural comfort and maximum hand-to-eye coordination.

Do not bend your wrist upward. Make sure you are sitting high enough for the workstation to be slightly below elbow height so that your hand rests naturally on the mouse.
Mousing demands a certain level of surface stability; if used on a keyboard tray, the tray should not wobble or tip.

A trackball has an exposed ball that you manipulate with your fingers. It requires the use of different muscle and tendon groups than does a mouse, and can add variety to your manipulation of computer information. Some trackball designs, however, may cause discomfort and possible injury to the area around your thumb, which stretches and reaches to maneuver the trackball.

Test different models of mousing devices, trackball or other input devices. Consider the shape and size of the devices, how comfortably it fits into your hand, ease of operation, and any special features that might make your job easier.

I am working with computer from 8 to 5pm daily, the only moment when I leave my desk is during my break time. So I guess I should learn from this lesson, sitting posture is important.

Another news to make me happy today would be this HEARTLESS JERK IS FINALLY DYING!!! Read more here Courts rejects Canny Ong's murder appeal, lets clap for Ong's family.
