It's not just the most physically demanding jobs that can lead to serious injuries. Working with a seemingly harmless mouse and keyboard can cause chronic injuries just as easily as hauling a load of cement. In fact, repetitive strain injuries such as carpal tunnel affect hundreds of thousands of American workers a year, and lead to tens of billions of dollars annually in workers comp claims, according to the Occupational Safety and Health Administration (OSHA)。
Nelson Liu, a certified acupuncturist in Los Angeles, sees many of these disorders in his patients. "People who sit at desks and work on computers come to me with chronic pain in the shoulders, wrist, neck, and eyes, and they often result from the small, repetitive motions they do on the job every day," Liu tells Yahoo! HotJobs。
Common Injury Causes
The top culprits of what experts call repetitive strain disorders include:
Sitting in an unnatural posture for a long time。
Not allowing recovery time。
Repetitive motions, such as using the phone, typing with bent wrists and using a mouse。
Using force or pressure, such as pinching pens, gripping the mouse too hard, or pounding the keyboard.
Even emotional stress can lead to strain and pain. "People are particularly stressed out right now, and often emotional stress turns to physical stress, which turns to worse posture, which turns to pain, which turns to more stress," says Wendy Young, a certified ergonomist in Houston and author of the e-book, getinsideyourcomfortzone.com.
