The Institute of Practical Psychophysics was founded in 1990 by the President of International Academy of Non-Linear Diagnostic Systems, honorary member of Academy of Medical and Technical Sciences, Vladimir Igorevich Nesterov. The Institute of Practical Psychophysics (IPP) is a scientific research institution, mainly oriented towards practical researches in bio-resonance diagnostics and therapy field. The most advanced achievement of the IPP is non-linear diagnostics (NLS). NLS diagnostics based on bio-resonance methods make it possible to evaluate the degree and intensity of functional changes in a patient’s organism. Today, the Institute of Practical Psychophysics deals with design, development, production, servicing and sales of hardware-software bio-resonance diagnostic systems. IPP has also established clinical centers utilizing their NLS technology: one in Russia (Omsk) and one in Central Europe (Prague).
