The aim of biofeedback is to assist the patient in focusing on the awareness of some cluster of internal state or events, in developing skills to modify or moderate that cluster, and then, in the service of biologic utility, to allow that awareness to fade away, so that the cluster once again has been internalized, while the skills for its modification or moderation are maintained. It is the enhancement and control of biological awareness as a state of consciousness. The end product, then, is self-regulation of internal events or states which previously resulted in distress. The process is much like that of learning a motor skill, wherein the conscious awareness of the sequence of motor events is high early in the learning, but progresses to an internalized, coordinated response as proficiency is achieved. Active control of airsickness by biofeedback training is possible, and offers a new approach to the control of this distressing syndrome beyond passive accommodation and beyond medications.
