During the procedure
During a biofeedback session, a therapist attaches electrical sensors to different parts of your body. These sensors monitor your body's physiological state, such as brain waves, skin temperature, muscle tension, heart rate and breathing. This information is fed back to you via cues, such as a beeping sound or a flashing light.
The feedback teaches you to change or control your body's physiological reactions by changing your thoughts, emotions or behavior. In turn, this can help the condition for which you sought treatment.
For instance, biofeedback can pinpoint tense muscles that are causing headaches. You then learn how to invoke positive physical changes in your body, such as relaxing those specific muscles, to reduce your pain. The ultimate goal with biofeedback is to learn to use these techniques at home on your own.
A typical biofeedback session lasts 60 to 90 minutes. The length and number of sessions are determined by your condition and how quickly you learn to control your physical responses. You might need at least 10 to 15 sessions, which can make it more expensive and time-consuming. Biofeedback might not be covered by insurance.
