Biofeedback refers to a number of clinical techniques which provide feedback concerning the changes in a particular physiological response that the patient is unaware of, so as to enable the patient to modify the physiological response and to deal with it.
The first step is to understand which muscle groups in the body becomes tense when the person is in a in a state of anxiety Once this realizations sets in the next step is to use this finding, along with the help of any relaxation technique, to relax these muscle groups consciously. This mechanism helps the patient to consciously try and reduce or alter the physiological changes that occur frequently under stressful conditions.
- The first step includes creating awareness about the physiological changes taking place within the body in a particular state.
- The second step involves transforming this awareness into signals, usually with the help of a biofeedback machine.
- The third step includes utilizing these signals to control the physiological state and alter it to normal or relaxed physiological state.
