@sueinmn thank you so much for these details. Along with the monopoly that Power Plate feeds those that show interest, getting hard science is difficult to come by on vibration plates. Chances are, if you use one, you are also doing many other things to combat osteoporosis. So, my question when someone says that they experienced results is, what else are you doing?
I conclude that the plates may be helpful for other issues, may help increase or enhance certain exercises but the jury is out when it comes to how it effects bone density. With that said, everything points to weight bearing exercises and movement. No shortcut there and there is documented studies that indicate how beneficial exercise is for our condition as well as quality of life in general.
Thanks again.
