I have been using a Marodyne for almost 4 years since finding out on my first DEXA scan that I had osteoporosis which was a shock since I was a runner. I got a DEXA scan after two years of 3x per day use of the Marodyne device. My scan showed significant improvement in both femoral and spinal T-Scores. It was an increase in bone mass of 8.8% in the hip and 3.9% in the spine. This is practically unheard of from what I've been told without medication. Now I'm -2.2 in the femur and -3.0 in the spine. My score actually went from osteoporotic to osteopenic in the femur. The endocrinologist was so surprised - she kept asking me to verify that I was not taking any medications for osteoporosis. The only other thing I'm doing is taking genistein supplements along with vitamin D, boron, and mushroom extract supplements (combined) Maitake, shiitake, Turkey Tail. I am getting another Dexa after a two-year interval this month. If I just hold steady at this point, I'll be very pleased. I also do yoga modified for those with osteoporosis and walk about 5 miles per day. I think the Marodyne is really working.
