Wearing wrist braces while typing can actually increase injury. They should be worn when not working, especially during sleep, because a large fraction of RSI injury is accumulated by a number of people that exhibit nocturnal contracture during sleep (drawing of hands to chest centerline, bending and curling of the wrists and fingers also). Also, light strength training is often very helpful. I went through RSI in my early 20's (while writing a research compiler), did a ton of research and have been symptom free for two decades.
