The Downside of Mobility: Injury

Injuries from using mobile devices ...

"As publicly accessible Wi-Fi access points come to more and more coffee shops, libraries, and other venues, people are using laptops in environments that compromise comfort and often precipitate pain. That's because on a notebook computer, the monitor and keyboard can't be independently positioned.

"That insists that you crane your neck to see the screen," says Lenore Bryck, a pain-relief and massage therapist in Amherst, Massachusetts who works with clients suffering from chronic pain and repetitive strain injuries. But if you elevate your laptop so the screen is at an appropriate height for your neck, you've moved it out of the comfort zone for typing.

"And then you've got the whole gamut of injuries to your wrists and hands," Bryck says, which aren't so different from the problems a person can have with an improperly arranged desktop computer, but they tend to be worse. Carpal tunnel syndrome, in which several fingers can feel numb because the nerve leading to them gets inhibited, is a well-known problem, but pain can range from the fingertips through the arms, shoulders, neck, and back due to the combination of poor keyboard and monitor placement.

In 2006, the most recent year for which the US Bureau of Labor Statistics has data, there were 13,010 reported workplace incidences of carpal tunnel syndrome. Although the data don't track how workers got carpal tunnel syndrome, computer use is likely a significant cause. Carpal tunnel syndrome accounted for 3.6 percent of all workplace musculoskeletal injuries in 2006. That figure was 4.4 percent in 2005 and 4.6 percent in 2004. While the slight decrease might suggest improved ergonomics for some workers, Bryck and others say overall incidence of discomfort—if not, perhaps, diagnosed carpal tunnel syndrome—is on the rise. One reason the labor statistics don't reflect that is the shift in demographics. Increasingly, younger computer users are complaining of pain—college, high school, and even middle school students.

The ubiquity of laptops that extends down to some of the youngest users reflects an overall industry trend.

"Portable PCs represented 40.1 percent of all PCs sold worldwide in 2007," says Michael Shirer of the research firm IDC. That makes them hardly peripheral to the overall PC market, which is where they entered the playing field—intended for occasional use that complemented a desktop machine.

You don't have to work in pain

Importantly, pain and conditions such as carpal tunnel are not inevitable results of notebook computer use—at any age. Occupational therapist Gail Hegeman of Pioneer Ergonomics in western Massachusetts says as more people in their 20s find their way to her—often because of acute non-computer-use injuries, she's astonished at their attitude toward pain.

"They almost act as if it's normal" to experience pain from using their computers, she says. "They say to me, `oh, well, I just work in pain.'" It doesn't have to be that way."    (Continued via Datamation, Amy Mayer)    [Ergonomics Resources]

I have suffered from carpal tunnel syndrome on & off for about 18 months and like to continue my research into the ailment regularly by checking out related blogs. That's how I found myself at your site.

I tried about a dozen different products and treatments ranging from cortisone through to prescription NSAIDs and everything in between. About 2 months ago I came across a product called Penetrex via a referral from a guest I had in my home through a family memeber. He is an orthopedic surgeon who knows his stuff and he said to try it because he had been hearing good things about it.

Anyways...to make a long story short...the stuff works. It is what is known medically as a transdermal anti-inflammatory. It is not some miracle snake-oil that claims to offer an overnight cure. What it did do was reduce my suffering dramatically within about 1 week and my level of pain has not returned but instead continues to improve incrementally.

Give it a try....it was developed by a pharmaceutical biochemist and it comes with a no questions asked guarantee. If you're suffering to the same extent I was I can assure that giving it a try is well worth the 20 bucks.

And NO!...I am NOT affiliated with the product in any way and have nothing to gain by telling other people about it. I simply know what it's like to suffer with carpal tunnel syndrome both physically & emotionally. I also sympathize with those spending time and money looking for SOMETHING that helps. For me, Penetrex was very effective.
