"Bottom Line Up Front (BLUF): Thank you, Naomid, for your post, which I'll partially quote here, to spread the news:
"Yes and yes. I've read every study to date. Here are a couple:

We bought the Marodyne LIV almost a month ago, like others, out of fear and with the strategy to, "leave no stone unturned," in our search for effective treatments. After nearly a month of searching for ANY research, (other than that sponsored by the inventor, Dr. Rubin, or his cohorts), we were about to send it back for a full refund, until we found the study you publicized in you post, published by National Institute of Health (NIH). That's the ONE positive, independent study I needed in order to keep and not return the LIV device. The other study you included in your post had no value for us, as it's results were inconclusive, AND, is was sponsored by a cohort of Dr. Rubin, the inventor. Thanks, again. Let's all keep up this very helpful conversation, and thanks to MayoClinic for facilitating this discussion.
It sounds like you decided to keep the Marodyne LIV based off of the results in https://pubmed.ncbi.nlm.nih.gov/33314313/. If that's correct, actually that study was published by the Journal of Bone and Mineral Research, not NIH, though the investigators received grants from NIH to conduct the study. (Pubmed is a search engine to biomedical and life sciences literature and is maintained by the National Library of Medicine, which is part of NIH.)
I admit I only skimmed that article after you referenced it. It seemed the study was small (n=80 total); included only postmenopausal women with normal bone density or osteopenia (low bone mass); did not take into account nutrition, exercise, fracture history, and other factors; etc. The study may have been more meaningful to me if it had used postmenopausal women with osteoporosis (though that may be deemed unsafe or unethical).
I continue to wait for more evidence (including VIBMOR trial) regarding vibration platforms. Perhaps they are helpful for persons with osteoporosis who have a sedentary lifestyle or can't do weight-bearing exercise. I am grateful that I'm physically capable of doing weight-bearing exercise. And it doesn't require a major outlay of money either!
