this is from another poster:
Dr Clinton Rubin holds the patent on the Marodyne device and is still promoting it, as a medical professional, on YouTube as of October 2022. He conducted the original study for NASA in 2001 which has since been archived by NASA. And now it is advertised on the Marodyne website as originally developed for astronauts. It was a research tool in one study that Dr Rubin did for NASA but has never been approved by NASA in any way. It's a lot of smoking mirrors for the most part.
I know nothing about Dr Rubin personally and had never heard of him until 2013 until my first appointment with my endocrinologist and she gave me a paper they had written, along with his wife, about low intensity vibration and the Marodyne machine specifically. And it could only be the Marodyne. In fact my doctor gave me their business card with the number to call. My problem today is that it is still be promoted by Dr Rubin and Marodyne in vague medical jargon that makes it difficult for the average consumer to decipher exactly what it does do for bone heath.
