Carpal Tunnel- Laptops Better than Ergo Keyboards? 90
An anonymous reader asks: "I have chronic tendonitis in my wrists (I think of it as incipient carpal tunnel syndrome). I shied away from laptops for years, thinking the cramped keyboard would aggravate my condition. About six months ago, circumstances forced me to break down and get a laptop. I didn't have any major problems with the keyboard - it's only now that I've switched back to a wireless mouse and an ergonomic keyboard that I've started to have any pain. Amazingly, the laptop is more comfortable for me to use long term. Has anyone had a similar experience? What's the explanation? Is it the shorter stroke depth on the keys? The fact that you can put your hands closer together than on a standard keyboard?"

Well, let me take a stab... perhaps we have a tendency to position (and reposition) the laptop however it feels most comfortable. Maybe it's just giving better variety?

That may be the main difference - with the laptop you may not even be using a mouse.
May help if you get a bigger and flatter mouse which doesn't make you scrunch your hand together to hold. YMMV.
Or use a trackball or some other pointing device -that'll probably help more.

I've got both a desktop and a laptop here at my desk, and comparing my typing positions for the two, my wrists are much straighter when typing on the laptop than on the desktop, because the laptop keyboard is a good foot farther from me than the desktop keyboard.

The plate was bent over at the wrist to push her hands backward (like you are stopping a car with a hand signal). The device also tended to rotate the hands laterally (away from center line). The position gave her significant relief from ct symptoms.
the orientation of your wrists while typing on a laptop is typically very different than typing on a normal keyboard. I'd bet that the angle in your wrists while typing in the laptop is such that it afford more room in your carpal tunnel for the tendons and they don't rub around so much.

It's the MOUSE! (Score:5, Interesting)
I never had trouble with my wrists. Ok, occasionally my wrist would hurt from putting all of my weight on it, but that was a skin-deep problem, not a carpel-tunnel or tendonitis problem. Then I got a summer job using Visual Basic. VB takes mouse usage to new heights, and within 2 months I had serious problems. Fancy keyboards, special extra-large mice, wrist braces, etc. didn't help much. I learned to mouse with my left hand, and that helped since I could spread the stress out. Even after I left that job, I had problems with my right wrist.
Then as I was starting a new job and getting set up with my office equipment, I asked the hardware guy if he had anything that would help with wrist problems. He gave me a "Microsoft Trackball Optical" (some prefer the the "Microsoft Trackball Explorer", so try them both). To make a long story short, over the next 3 months I stopped needing my wrist brace, and over the past 2.5 years, I haven't had any serious trouble. I now have a mouse (any mouse) and a Trackball Optical hooked up to every desktop computer I own. Most of the time, I use the trackball. When I do something where the trackball doesn't work well, I use the mouse.
Looking back, I've done a little bit of research. It turns out that the Microsoft Intellimouse I was using back then has become famous for causing wrist trouble. When it was designed, they did customer studies to find out what shape people liked best, and people chose the old Microsoft Intellimouse as the most comfortable. That was fine for short-term use, but over long-term use, it turned out to be terrible. The hump at the back forced you to bend your wrist. Newer designs have removed this hump.
So don't necessarily blame the keyboard! Try a mouse alternative, or at least make sure your current mouse is well designed (if you are using an older Microsoft mouse, get it replaced immediately, and stomp on it before throwing it away so that it won't ever be able to hurt anyone ever again!).
In addition, get your workstation layout evaluated. Either study up on it yourself, or get somebody who knows about it to evaluate your office for you. Here are a few key points:
Start with the chair. Your feet should firmly reach the ground. You should sit up straight.
When sitting up straight, your eyes should be lined up with a point on the top half of your screen. If you tend to slouch (like I do), your eyes should line up with the top of the screen. If you tend to sit up straight, your eyes should line up with a point 1/3 of the way down the screen.
Your keyboard should be positioned so that when you are in standard typing posture, the part of the arm above the elbow is hanging straight down and the elbow makes a 90 degree bend so that they are parallel to the floor. This should allow you to type with NO VERTICAL BEND in your wrist. The keyboard should be positioned horizontally so that the "6" key lines up with the center of the monitor. Don't line up your keyboard's physical center with the monitor -- line it up so that home row is centered. If you have a split keyboard, this can allow you to type with no bending AT ALL in your wrist. If you have a normal keyboard, your wrists will have a slight bend to one side. That is bad, but acceptable. It isn't acceptable for one wrist to be bent more than the other. And it isn't acceptable for there to be ANY vertical bend.
The mouse needs to be placed so you can switch from keyboard to mouse without moving your elbow (which is directly beneath your shoulder, remember?). Unfortunately for right-handed people, that put
