Are you trying to increase bone density? If so the Marodyne has not been proven to increase bone density. It was supposed to be used for NASA but since it didn't work to maintain or increase bone density they chose something else.

I can't locate all the information and place it in one concise post, but I believe even their website does not claim to increase bone density. I forgot the wording. But in other places I read things that don't say, proven to"increase bone density."

There is/was a current study which might be one that finally settles the issue, but for $3K I need proof that it works on it's own.

So many observations have included other practices like weight bearing exercise and medications - bottom line I have yet to see any research done using it alone to determine if it is effective.

I chose not to buy it based on the research I did.
