Wow, that is very shocking! There is another person on this site who used hers for 2 years and was very disappointed that her DEXA results did not show improvement either. However, my understanding is that the Marodyne does not build cortical bone but improves bone quality, the inner trabecular bone. I have been hesitant in buying one because of the expense and because I haven't seen any convincing studies or reviews on its effectiveness especially if you are already exercising by doing strength training. However there is a clinical trial that was taking place at the Australian Bone Clinic where they are using the Marodyne with their Liftmor program but the data is not in yet. Also although Marodyne claims they developed the machine with NASA there is no indication that NASA has ever used it for their astronauts to prevent or improve bone loss. So I'm cautious. Thank you for your review and input.
