Does Computer Use Actually Cause Carpal Tunnel?

BoldAC writes "A geek physician has reviewed the medical literature that explores if a relationship exists between computer use and carpal tunnel syndrome. 'Typing at the keyboard or using the mouse for hours and hours upon end just seems like it has to be horrible for your joints, right?' His conclusions certainly seem to contradict the thinking of many: 'The current research shows that computer use has very little role in causing carpal tunnel syndrome.' It even seems that both Harvard and the Journal of the American Medical Association agree with his conclusions."

Does this mean Emacs Pinky is just evil VI propaganda?

I have CTS

[earthloop]

I have CTS and am going for my op early next month to fix it. I'm 33 now and have used computers since the ZX81.

My GP insists that my CTS has nothing to do with my years of computer use, and that in fact it will be good post-op physio.

Still, I'm having one hand done at a time so that I can still manage one handed browsing. ;o)

One more thing

Now if they can just definitively show that masturbation does not cause blindness, geeks will finally be able to live worry-free.

Bullshit

[metalhed77]

This story is nothing new. What's really needed is a clarification of terms.

I have RSI (Repetitive Stress Injuries) and my carpal tunnel is just fine. It's the other nerves, tendons, and muscles of my hands which ache and cause the severe pain. If you try and explain this to people they just say 'Carpal Tunnel Syndrome' unless they're a doctor. Computer use DOES cause RSI which is the real problem, and a really painful and dangerous thing. Other tasks, sewing for instance, can also cause RSI. The phenomenon is not new.

How the carpal tunnel got so famous I don't know, but the term has stuck.

Get physical therapy now.

I'm completely serious. I had the same problem as you, diagnosed as tendinitis in the backs of my hands, and it made typing at a keyboard all day extremely painful. Physical therapy for two months, twice a week helped immensely and I learned a number of exercises that I can do at my desk that eliminate the pain entirely, if not all of the tension. I'll have to do the exercises for the rest of my life (or stop using my hands for a few straight months and let them rest and heal finally), but they're ten minutes a day and not hard. Physical therapy may be expensive if you can't get it covered under your health insurance/worker's comp, but it's a cost you have to pay now in order to not be suffering for the rest of your life. It's absolutely worth it.

Plus, for any of you who have gone to a general practitioner who was entirely clueless about RSI, go see an orthopedic surgeon. That was my GP's recommendation and it was spot on. The surgeon knew exactly what sort of damage might have been caused, knew how to check whether it was muscle/tendon damage or nerve damage, and was the one who referred me to the physical therapist. Your GP isn't necessarily clueless, but he or she is a generalist. A specialist will (hopefully) have a lot better understanding of the specific problems and possible solutions that RSI entails.

Consumer Reports

[Itninja]

The latest issues of CR (I'm a subscriber) listed carpel tunnel as one of the most over-diagnosed health problems. Something about a for-profit healthcare industry....just sits weird with me. I wonder how many times it would be diagnosed at all if they couldn't get the insurance companies to pony up the dough.

Driving

[fishbowl]

I'm reasonably convinced that poor posture and hand position while *driving* contributes more tho CTS and/or RSI than typing does.
I think it's a serious confounding variable, that most office workers have those two things in common: significant time spent driving a car, and typing on computer keyboards.

My Personal Story

[curunir]

About 6 years ago, I had CTS. I had just about the worst posture, hand position and everything else you could possibly imagine. And, as a programmer who spends at least 40 hours a week in front of a computer, it was starting to catch up with me. However, around that time, a friend of mine invited me to come rock climbing with him. I liked it so much that I started going to a local gym around 2-3 times a week. And a funny thing started happening...my CTS started to go away. About 3 months into my climbing habit (yes...it's an addiction), I was free of CTS pains entirely. I still have just about the worst ergonomics you could imagine, yet I have zero pain.

What I believe is going on is that CTS/RSI pain is not caused by doing one thing too often or putting your body in one position too often. Instead, it's caused by not doing other things often enough or putting your body in other positions often enough. I don't have any proof of that except for my own personal experience and the experiences of others that I've told, but those seem to indicate that bad posture/ergonomics can be counteracted by regular exercise of the affected area.

And some people smoke till they're 90 and don't get cancer, yet there doesn't seem to be any confusion about what's causing what there.

Unlike smoking, where lung cancer susceptability is likely in the high 90's of precentile, CTS susceptability is very low. Most people will not get CTS no matter how much they use a computer, whereas most people will get lung cancer from smoking.

The difference is in the likelihood rate, even though both of them are fairly equally the same thing. (Triggering a susceptability.)
