I too listened to the interview and she clearly says the Marodyne did not improve bone. As an owner of a Marodyne I'm certainly disappointed but not surprised. The one year I used the Marodyne daily for up to 20 minutes total in 2 sessions a day I had my worst decline in my DXA scores. I was also doing heel drops 5 days a week and various other exercise. Anyway it certainly did not help me but I was still hoping it would help others. If not out of the kindness of my heart at least I would be able to sell the thing if the study results were good. I still want to read the study results when they publish but I have no hope it will validate the device.

As far as vibration plates go it is possible that other plates using different frequencies and length of motion etc could help bone but there appears to be considerable potential danger in increased vibration beyond what the Marodyne employed.

Of interest to me is that Dr Beck mentioned that they accidentally were not having the subjects do their usual 85% of one rep max for 5 reps per set. The result being that they did not get the bone density improvements they got in the 3 previous studies. So heavy intensity with weights works and medium did not. The remaining question would be what if you increased the repetitions with those medium weights. That is if you increased the repetitions to the point that you felt like it was taking as much effort as the heavier weights at lower reps. Would that extra exertion perhaps bring back the bone growth even with using less weight? I would like to know the answer to that as it's really scary to lift heavy with my -4 spinal T score.
