Biofeedback diagnostics consists of real time scanning of electromagnetic and sound waves emitted by the body for detecting alterations in physiology of different organs and systems. There are several different types of feedback based on measuring electromagnetic, sonar and heat waves radiated by our skin, muscles, brain and internal organs. A comprehensive biofeedback device monitors respiratory, cardiovascular system, central and vegetative neural systems, excretion and reproductive systems. Every organ and cell type has its own spectrum of electromagnetic waves, with unique frequencies, wavelengths and temporary patterns. In the case of pathology, the system detects and quantifies the alterations in certain wave diapasons and interprets the results in a form of readable report. Then feedback therapy is applied to fix the problems with the body systems and cleanse it from harmful bacteria and other pathogens.
