I sometimes would put on ShopHQ and accidently came across the vibration machine. Watching the presentation they talked about what it can do for the joints and things like that. I went to amazon and searched thru a bunch and began reading reviews and what they had to say. So decided to go for it. I didn't want a junky one. Also had watched them on the Q and HSN [ tony little]
They all talked about how it helps move the lactid acid build up in the joints.
Really helps my husband with his sciatica. The buttons range is from 1-99. We are still on the lowest. It can also help with balance. You can stand on it or sit and put your feet on it, sometimes I even sit directly on it. Sometimes my husband will tell me his sciatica is acting up and I say get on the machine, and he says 'oh yea'. It works. He is in construction.
