PHYSIOLOGICAL BACKGROUND

The nervous system is the primary computing system of the human body. The sensory nervous system detects any damage done to the body from both outside and inside and sends the information, at the earliest stage of pathology, to the central nervous system. Due to the specific structure of the nervous system, this information also reaches certain skin areas (Convergence Modulation Theory), causing changes in the skin's bioelectrical properties. This phenomenon opened new and logical opportunities for medical diagnostics. OED is the first clinically proven method of this kind which accesses the body's own information system, the 'first hand' source of diagnostic information.
