I am involved with BEMER and I have seen 3 different children get results you would only call miraculous. I suggest you look more into it from whoever you heard about it from.
One thing I can tell you is that BEMER does not consider itself a PEMF device although it uses PEMF to deliver it's technology. There is not another PEMF device out there that increases bloodflow in the microcirculatory system as BEMER does. They are in a class of one with their technology.
