The Bio-Feedback monitor gives the therapist a very accurate indication of the client's current emotional state when they first arrive for treatment, a datum point from which to work from, and consequently shows the client's improvement as therapy progresses. This feedback is useful for both client and the therapist. It gives the therapist a very clear visible indication of how a client is reacting to a hypnotic induction and how they are feeling at a subconscious level whilst in hypnosis.
