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!
