Hi there,
No, I hadn't heard of it, so I looked it up. I think it looks pretty interesting.
Didn't find anything too informative but its inventor, Dr. Donald Rhodes, has a clinic website in Corpus Christi, Texas - quite a good website, well written and not pushy at all.
I think their approach looks really sensible, everything is geared to improve the circulation and get more blood into the affected areas. I personally think that's crucial.
Here's the appropriate web page:

Here's a "my story" from a 16 year old who's had RSD for 8 years:

If there was one of these machines here in Hong Kong (but maybe there is, I'll check it out) I'd definitely give this a go.
Thanks for letting us know about it - have you tried it, or are you going too? Most machines I have a problem with when used directly on my hand (too much vibration, movement I can't control etc), but somehow - just guessing - this doesn't look like it'd be like that.
Let us know what it's like, please

all the best.
