The term bioresonance therapy was coined in 1987 by the Brugemann Institute for therapy with the patient’s own oscillations. The idea can be quickly outlined: all diseases and their pre-conditions are accompanied or to be more correct, caused by electromagnetic oscillations. There is no pathological phenomenon without the presence of pathological oscillations in or around the body. Since the patient’s own oscillations or signals are electromagnetic in nature, they can be picked up from the patient’s body using special electrodes . These electrodes consist of several layers and contain a specially prepared magnetic foil with a field strength corresponding to the maximum magnetic field of the Earth, which according to scientific calculations was around three times stronger in earlier centuries than it is today. There various types of resonance therapy. One type is called type Ai. This therapy means that physiological and pathological oscillations are inverted and was used almost exclusively in the first four years of bioresonance therapy. Bioresonance can be used as a diagnostic tool. It is effective to perform Electroacupuncture according to Voll (EAV), durg testing, detection of scar interference fields, allergy testing, geopathic stress, etc. It is very useful for the treatment of any diseases using exactly what each patient needs. The programs can be divided in basic therapy, meridian related therapy, therapies according to indications and special programs. I could say, it is an electronic homeopathy.
