- As other people have pointed out, you should check out sci.med.occupational,
- and the associated FAQ for that group. I'd suggest that you try the
- following things:
-
- 1) Seek medical attention. You should be able to file a claim
- under a Worker's Compensation program, since your problem is
- probably work related. If left untreated, your hand and
- wrist problems can develop into severe tendonitis or even
- Carpal Tunnel Syndrome. The earlier you have it checked out,
- the better. [Worker's Comp might not be an option if there
- are other non-work things that contribute to the problem, such
- as extensive guitar playing, and other such things. However,
- you should try.]
-
- 2) Get information on how to setup your work environment so that
- your desk and keyboard are at the proper height, and your
- posture is correct. This can go a *long* way toward solving
- your problem. You might also try to work with your HR
- department to get adequate in-house education on ergonomic
- issues for keyboard-intensive environments. Your employer
- has a responsibility to provide you with a safe working
- environment, and a lot of large companies have people devoted
- to ergonomic issues.
-
- 3) Avoid "improper" wrist motions. With an HP keyboard, using
- emacs, I frequently use function keys just to the right of
- the normal keyboard keys. My right hand had a much more
- serious problem than my left hand. What I found was that
- I was rotating my hand at the wrist to access these keys,
- which is a definite no-no. I've been retraining myself
- so that I instead move my entire arm over to that location,
- via a combination of small shoulder and elbow movement.
- This has helped my condition remarkably. Your problem
- with the control key might be solvable with similar
- changes. Move common functions to single function keys
- (especially arrow keys for motion), and learn how to
- access those keys without bending your wrists. It takes
- a fair amount of work to break the old habits, but it
- is certainly worth it. (In my case, I wore a wrist brace
- for a couple of weeks when the problem was most severe,
- and I learned very quickly just what movements I was making
- that moved the wrist. I still haven't completely retrained
- myself, but I'd say I do the right thing with the function
- keys about 80% of the time.)
-
- 4) If you use a wristpad, do *not* use it for weight support
- while typing. That was another thing I was doing wrong.
- (In fact, there is a worn and dirty indentation in my pad
- where my right hand rested while twisting the wrist to
- access the function keys.) Rather, if one is used, it
- should only be used as a "guide" to keep the hand and
- wrists at an even height, and allow smooth motion as you
- move your hands from side to side. The temptation to use
- one incorrectly might be too great, and perhaps you shouldn't
- use one at all.
-
- I don't think you have to switch away from emacs. Just use it more
- sensibly, and learn good typing habits. And do it soon --- the less
- severe your problem is, the easier it is to correct.
