I'm really pleased for your daughter that she is getting better but this is no miracle! It is truly nothing more than a TENS machine. If you don't believe me, have a look at the formal FDA approval for the medical device they are using. Its public information available on the FDA website
It is a simple, multi-channel TENS machine and is identical to existing TENS machines already on the market and made by other companies. It's just sad that some people have paid so much money for a treatment that isn't revolutionary and is delivered by a very cheap, long-established piece of medical equipment that has been in existence for a long time. What is a miracle, is that they can get away with charging $0000 for this.
