The human body is made up of energy, and that energy is composed of frequencies. The device reads these frequencies and measures the reactance scores of these frequencies and can detect when a frequency is out of balance. We generally experience these imbalances as some sort of sensation. We may refer to theses imbalances such as pain, anxiety, stress or other physical symptoms. The INDIGO with the direction of a certified biofeedback specialist, can then help balance these imbalances and reduce the stress in the body and assist the body to restore itself to a healthy state.
