What you can expect

During the procedure

During a biofeedback session, a therapist attaches electrical sensors to different parts of your body. These sensors might be used to monitor your brain waves, skin temperature, muscle tension, heart rate and breathing. This information is fed back to you via cues, such as changes on a monitor, a beeping sound or a flashing light.

The feedback teaches you to change or control your body's reactions by changing your thoughts, emotions or behavior. 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 make deliberate physical changes in your body, such as relaxing 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 30 to 60 minutes. The length and number of sessions are determined by your condition and how quickly you learn to control your physical responses. Biofeedback might not be covered by insurance.
