I bought and am using the Marodyne but I recognize that I did so out of fear, wishful thinking, and a reluctance to take medication for my osteoporosis. My latest doctor said the sample size in their research was so low it was meaningless. She said it might help with balance though. So, I still use it 2x most days and use that time to go through old books and do breathing exercises. If it helps bones I've changed my lifestyle so won't likely know the outcome anyway. I agree about the mutual admiration society and that's concerning.

There is a study in Australia called Vibmor which is testing the Marodyne LIV in a clinical trial. Results are probably being published in the spring of 2024. They are testing it against the Liftmor exercises that have shown to build bone in clinical trials and is being used at the Bone Clinic in Australia. There have been other threads which have discussed the Marodyne some have been pretty negative implying that the Marodyne is not effective for BMD . I have not come across anyone who actually had a better Dexa score after using the Marodyne. Pretty expensive investment but Im waiting for results from the Vibmor clinical trial.
