Myself, I had already switched to Colemak when I developed RSI due to heavy typing at my work. What did it for me was the unnatural position of my hands, wrists bent upwards and outwards in order to fit onto the "tiny" laptop keyboard.

The solution was simply to switch to a run-of-the-mill ergonomic keyboard (ERGO K860) and surprise, surprise, my RSI lessened and eventually disappeared in 2 weeks or so.

So, for me it was definitely the hand posture, NOT the layout that caused the problems!
