Neuroreflexive pain therapy (cold stimulus therapy) is a natural and now indispensable technique for the daily treatment of acute and chronic conditions. Cryonic technology uses liquid CO₂ to stimulate the neuroreceptors in the skin. This effect is achieved through very low temperatures, high pressure, and vibration. The reflex reaction of the neurovegetative system to this stimulation forms the basis of the treatment. This specific stimulus is referred to as thermal shock and is triggered at temperatures below -60°C.
