Biophysicoclinical process and device to implement it. It initiates the emergence of a clinical approach to pathologies understood and treated within their somatopsychic global nature. The fundamental basis of the process consists in producing and overlaying in a volume of exposure—containing part or whole of a living subject, animal or human being—a magnetic field and one or several very high frequency electromagnetic fields, the latter being essentially angle modulated. The biological effects thus produced are many and varied they can be observed, in particular, in the stimulation of certain defence systems of the body, such as the intensification and reinforcement of the immune defences.
