I was very skeptical but I had done some special ed training at a Minds-in-Motion center a few years ago and remembered that they used commercial grade vibration plates for vestibular stimulation. I had a sudden onset of balance problems recently, so decided to invest in the Waver. Even if it didn't help, if I used it judiciously, it wouldn't hurt. It is actually helping. I might never stand on it but it definitely helps with blood flow and edema.
