I don't know. I figure it's worth a try. They have been doing this for quite some time. My doctor (www.drKalish.com) has employed it for a lot of years and consults regularly with Dr. Hinz. He just returned from a conference he said was attended by several physicians, some with PD. He says Dr. Hinz has roughly 3 million patient hours of records from the doctors who use it. Of course, I just have his word for it.
