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."

Driving

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.

I hate to keep copying/pasting the same thing here, but this might actually help someone. Check out the following as it may help you:

I cured what I thought was "RSI" using this "mindbody" approach:
http://www.rsi.deas.harvard.edu/handout.doc
(Coincidental that Harvard is hosting this document, maybe the researchers should look at it themselves)

Here is the Google cache for those who don't want to open a .doc.

I suffered for 1.5 years (where I didn't work because I didn't think I could) before I found that my cure was a completely psychological approach. From my research of CTS (as well as what my doctor told me), it is completely unrelated to typing. And from my experience with "RSI" and understanding what it actually was, I no longer believe you can actually hurt yourself from typing too much.

I now type sometimes all day long without taking many breaks. I play guitar, bass, and drums. I don't worry about posture at all. Ergonomics are only a way for me to get comfortable, not to avoid injury. I have no pain at all, and don't worry about ever having "RSI" again. It's been 5 years since I cured myself.

Please read up on the approach I'm talking about here before you flame me. It actually makes sense once you put all the pieces together. You can also search for "sarno tms" to find more info.

Read the book "The Mindbody Prescription" by John E. Sarno if you can, its really the best source for an explanation of this.

No, because Grammar Nazis nitpick over insignificant details that do not actually apply to the actual grammar of the language. Few people really screw up grammar, but rather, they fail to uphold the arbitrary rules emplaced upon the formal language that Grammar Nazis nitpick upon.

"I ain't got no money" is actually entirely grammatical (from a linguistics point of view), however it fails to meet the standards of formal language that Grammar Nazis prefer.

Interestingly, it could be related to Plato's Allegory of the cave. Grammar Nazis actually understand grammar little better than the average native speaker, simply they are dogmatically bound to believe that the shadows are reality, and that the arbitrary rules they have established to explain grammar are what grammar is really about.

Those who have gotten out of the cave, and see the reality of grammar, and the entire flexibility thereof, understand better than any Grammar Nazi why the above phrase was actually grammatical. And when they would attempt to explain why it is actually grammatical (it's SVO order, it's negated, and has appropriate concordation with the negation.) the Grammar Nazi looks at his cave wall and says that those reasons don't exist, because "ain't" isn't a word, and a "double negative" would logically make a positive.

Grammar Nazis are to grammar as Chiropraters are to medicine, because neither actually really practice the science described. Rather they study fringe elements related to that science, and believe their positions to be equally valid as the actual science itself.
