I would disagree about not using wrist braces; my doctor recommended I use one when I was experiencing wrist pain several years ago, and it helped a lot. A lot of RSI conditions are caused by pinched nerves, and the immobilization of the wrist prevents the sort of bending that leads to pressure on those nerves, allowing it to slowly be relieved over time. They don't help mitigate the pain, they help treat the cause of the pain. It helped me to wear them while working, but I also got a lot of benefit out of wearing them while I slept, ensuring that my wrists were perfectly flat and healing.
