I was interested in nailing down the "qi skills increase" to "fascia tissue increase" link. If there is a demonstrable link then it stands that an apparatus that specifically stimulates the tissues may lead to more rapid effects than traditional methods alone (this may be a bad thing).
Yes, there are a few mechanisms that do that; they're all more or less related. I mentioned (in a general way) how to do one in a post I made on Aikido Journal a couple of years ago. It's not very complete, but it's not a bad start.
