A bi-product of today’s computer usage (which includes its limitless capabilities of the keyboard) has resulted in an increase of Carpal Tunnel Syndrome (CTS), caused by repetitive movements, like typing on a keyboard. With the average lifetime cost of CTS, including medical bills and lost time from work, estimated to be about $30,000 for each injured worker, employers must make an effort to recognize the causes, and solutions, of CTS.

Expensive Workers’ Compensation Claims

Workers’ Compensation costs can increase substantially with CTS claims. Within the hand and wrist there is a collection of bones, tendons and nerves. If you flex your hand over and over again, you cause these tendons in your wrists to rub against each other, leading to irritation. The irritation can result in swollen tendons pressed against the median nerve, causing tingling, numbness and eventually significant pain. If the symptoms continue to persist without any precautionary changes, this may cause extensive pain and limited hand use.

Other Causes

CTS is not only caused by repetitive motion, but may be caused by genetics, health/lifestyle and trauma to the tendons. While genetics can’t be changed, an ergonomically conducive environment and proper work habits can reduce the chances of developing CTS.

Preventative Measures

Here are some four simple precautions that may be incorporated:

• Chairs – Wheeled, adjustable height chairs with armrests are ideal, because you’re able to adjust the back rest of the chair giving custom support to your back. While, the armrest allows you to rest your arms and take weight off of your shoulders.
• Tables – Choose a table/desk height that allows your arms to sit at a 90-degree angle to your body (27 to 29 inches above the floor is recommended).
• Wrist angle – Adjust your keyboard height or use wrist rest to align your wrists with your forearms while working. Consider changing your style of keyboard, using a track ball or a different mouse if you cannot achieve this position otherwise.
• Elbow angle – Raise your seat height if your arm angle is less than 90 degrees. Lower it if it is more than 90 degrees.
