NASA scrapped the whole concept of Low Intensity Vibration by any machine, at least that's the way I read it. Clinton Rubin didn't file for a patent for it until 2014 and the trial was ended by NASA in 2008. I see nothing that leads me to think the Marodyne device was even invented to be tested for the NASA Vibe Trial. Today he is one of the lead researchers for the VIBMOR Trial on LIV going on in Australia now. That appears to me to be a major conflict of interest since 2 companies Clinton Rubin founded directly profit from the success of the trial - Marodyne LIV market it worldwide and COPA Healthcare distribute in the US. He is also employed by BTT Healthcare in Germany who manufacture it, as their chief scientific investigator.
All that being said I'm sure this is nothing new in the realm of clinical trials and the goal of marketers of devices and drugs worldwide.
My personal decision from my experience has been to stick to therapies and devices that are FDA approved. I sold my Marodyne device back to COPA Healthcare, the distributor of them, in 2022. It appeared to be a company of 2 people located in Davies Florida. I got a hand written check from them for $540.00.
My current regimen at 78 years is I take liquid Alendronate once a week and walk a lot. I have seen my DEXA numbers improve by 6% in my spine and remain the same in my hip.
Good luck to everyone on this feed dealing with bone health at whatever stage you're in.
