I won't begrudge anyone who finds comfort in this "mindbody" stuff. If your pain is gone, good for you. But I
really really hope you folks won't take away the wrong lesson and assume that all RSI is mental. It's not.
Overcoming my own physical pain was tough, but I eventually conquered it. Here's what worked for me.
* I learned to type Dvorak. Since learning how to type on a C64 at the age of 3, my typing form has always been terrible. If nothing else, Dvorak taught me how to put my fingers in the right places.
* I picked up a split-in-two-halves keyboard. The right half of the keyboard is rotated counter-clockwise to address the extreme ulnar deviation in my right forearm (following an old injury).
* It's also nice, with these broad shoulders, to spread out the two keyboard halves. This helps a lot with my neck and shoulders.
* I tented that keyboard to ease pronation in my wrists. I started at about 70 degrees (almost fully vertical) and eased down to 15 degrees over time.
* I grabbed a vertical mouse to match my vertical-ish keyboard.
* I stopped leaning my head toward the screen. Huge help for my neck.
* I started using a sit-stand desk. This is a great way to "take a break" without actually taking a break.
Some other important observations.
* Being in good physical shape reduces all my RSI problems/risks across the board. When I'm fit, I can type in any awkward position for days without pain. When I'm fat, I get RSI just thinking about my keyboard. Being fit at the moment, all my new equipment and good computing habits are making me far more productive.
* Good sleep and good food also help. Sometimes I lose focus and slip back into bad habits when I'm in a cheesesteak coma, for example.
It may be possible to fix your RSI physically if you pay really close attention to what your body is telling you, and earnestly experiment with possible solutions. Some big organizations in SV have ergo labs where you can go test out equipment for free. Use that resource if you can. Do what you must, but don't discount the physical solutions.
