This workshop will give the scientific explanation for the basic principles of Bioelectromagnetic Medicine (Bioresonance), which utilises the effect of electromagnetic fields for the purpose of diagnosis and treatment. It will outline how bioresonance can effectively determine the deeper, root cause of illness and treat this true cause, rather than just the surface symptoms. Its methodology will be analysed as well as its application to the patient, at both a diagnostic and therapeutic level. A brief reference will be made to the history and evolution of Bioelectromagnetic medicine, and its fields of action described in detail with reference to scientific studies and clinical trials. The diagnostic devices used will be described and their basic operating principles analysed through the electromagnetic fields they are based on. The innovative, portable and wireless therapy devices used for treatment will also be presented and their mode of operation explained. The lecture will close with the presentation of clinical cases diagnosed and treated through this method.
