Six therapy types can be used in the BICOM optima device: A, Ai, H+Di, H, Di, and Ai+A. These therapy types separate physiological and pathological frequency patterns picked up from the patient's body and either return them directly, invert them, or modulate them differently before being fed back to the patient. Therapy types are selected based on the patient's condition, such as their energetic state, symptoms, or need for detoxification.
