I visited a new doctor a couple of weeks ago, who practices integrative medicine in the south Chicago suburbs. When I mentioned that I am looking for ways to increase bone density he suggested that I do a Google search on PEMF, or Pulsed Electro-Magnetic Fields. Now this is something new to me! However, according to articles I read on Google Scholar, it is not a brand new treatment. In fact, a review article about its effects on osteoporosis included over 100 studies/articles about it. PEMF has been used for years to treat bone pain in osteoporosis patients, but researchers have found that it also enhances bone formation in younger people with "secondary osteoporosis" but there were mixed results with older patients. Another article showed a positive effect of PEMF on bone density of rats. I've only read these few articles, so will continue looking for more conclusive studies.
