I don't know where she found them, but probably Amazon, to be honest. The brand is Disuppo. Here is the ones she got me.
I do a lot of writing/typing/etc. and have wrist problems. I have found that wearing wrist braces at night (as well as during activities sometimes) helps. You can write/draw with the Mueller ones somebody else mentioned, or the Futuro brand ones. It'll be a bit awkward but doable IMHO.
Another thing I've used in the past is compression gloves; they help more with my hand pain issues, but it's worth a shot if your hands bug you too. Much less movement interference, more help for the joints at the base of your fingers if those are an issue, but they won't provide much support for your wrist. (I think I have these.)
Good luck, if you find anything else that works or other good resources, I'm still looking for groups who field questions like this.
