I have searched for info on Vibration Machines and haven't come up with what I saw on some show about stuff in an old building for sale. It was a chair that vibrated FOR constipated patients. This caught my eye so I did a bit of research myself.

I learned that a vibration going through the body stimulates going. But how was a problem. How do you vibrate yourself. Easy when you think about it. Your heels. Raising and dropping your heels in a rhythmic pattern causes a vibration to go through your body. But you must concentrate and be patient.
