Using alternative keyboard layouts?
gommm: I've been using colemak for the last 3 months and the result has been very positive:
 - The wrist pains I used to have disappeared (since that was the main reason to switch, the switch is a definite succes)
 - It took me about 1 month and an half to regain my normal speed (my biggest problem was the inversion of 'r' and 's')I never really managed to type in a proper way (though I did touch type with 7 fingers, I didn't have my fingers in the proper row and the proper position), since starting colemak I started having a correct finger position since it just feels more natural to keep your finger in the home row when so many letters are there.
