BioFeedback
At CES we use traditional biofeedback when working with children who have significant problems managing their anxiety. Biofeedback is commonly used in conjunction with other interventions so that the child can get the most out of their treatment without having the anxiety interfere.
Similar to the EEG Neurofeedback, biofeedback uses computers only here it is used to teach the child how to create a calm state of mind. Once the child has learned to produce this state, he can bring it about whenever he desires.
