There is over 7,000 studies and clinical trials surrounding PEMF therapy including those done by NASA. The NASA space program observed deterioration of bone, tissue and depression in astronauts who are in space even for a short period of time. NASA determined the main causative factor for the degeneration was that the astronauts were outside of the norm 7.83 Hz natural pulsed electromagnetic field signals of earth. This research led to the development of PEMF Devices which could replace the natural 7.83 Hz electromagnetic field the earth naturally emits stopping the rapid degeneration of bone, tissue, and depression in astronauts. Since then, thousands of studies have concluded PEMF therapy as an effective all-natural healing modality including those done in our own Shealy-Sorin Clinic. PEMF technology continues to be be studied for further applications.
