Sounds like you’ve put time into looking into this more than some others. I actually have purchased a Marodyne and am using it. I have a positive outlook but I realize it will be difficult to assess its specific value for me as I’m doing lots of other things to assist in making my bone situation better. However, I would be curious to see specific reporting that says NASA didn’t use it, as well as specific reporting that’s more current., as what was sited was from 2001. Several years have past. So , I would be curious to see specific reporting that is more current. It takes years to gather data in some instances. Use of the these vibration platforms , the Marodyne, as just one of many on the market, impacts the trabecular areas of the bone. The spine is very much trabecular in nature and to a lesser extent the femoral neck area of the hip. Remember Bone Strength equals Bone Density plus Bone Quality. For many patients bone quality is as important , or more so in terms of actual fracture risk. As more people begin to get their Trabecular Bone Score in addition to the routine DEXA score , I’ll be curious to see if there’s a shift in the thinking. In the meantime I’d love to get more up to date scientific articles. I have an open mind and am all ears!!!
