That kind of RSI is caused by repeated rubbing along the carpal tunnel in your wrists. The more friction there is, the quicker it happens, so the idea is to keep your wrists as free from all forms of compression/pronation as possible so that the tendons glide as effortlessly as they can. Resting your wrists on something, having your wrists bent at bad angles, etc increase the compression and thus friction. Piano and guitar players with poor posture also suffer similar injuries for the same reason.

Other than that it's about recognizing the signs that your wrists are getting raw from too much use and taking breaks.

There's more than one type of RSI, carpal tunnel is only one particular injury.

I've had severe typing RSI and had to go to the doctor for it.. mine was tendonitis in the flexor muscles.

They looked at the X-Rays and MRIs of my wrists and said there was no way I would ever have to worry about carpal tunnel, different people have differences in the bones and can have a tighter tunnel.. a tighter tunnel can make that type of issue more likely to occur.
