It is absolute quackery-- as if a 9v battery an generate enough of a magnetic field to alter anything. I had a gap in my malleous bone several millimeters tall. I felt it was a insurance delaying tactic-- a way to postpone the needed surgery to just see if things got better on their own. This bone break lasted literally, 18 months.
