Biofeedback is a technique you can use to learn to control some of your body's functions, such as your heart rate. During biofeedback, you're connected to electrical sensors that help you receive information about your body.
This feedback helps you make subtle changes in your body, such as relaxing certain muscles, to achieve the results you want, such as reducing pain. In essence, biofeedback gives you the ability to practice new ways to control your body, often to improve a health condition or physical performance.
Your therapist might use a variety of biofeedback methods depending on your health problems and goals. Biofeedback types include:
You can receive biofeedback training in physical therapy clinics, medical centers and hospitals. A growing number of biofeedback devices and programs also are being marketed for home use, including:
Interactive computer programs or mobile devices. Some types of biofeedback devices measure physiological changes in your body, such as your heart rate activity and skin changes, by using one or more sensors attached to your fingers or your ear. The sensors plug into your computer.
Using computer graphics and prompts, the devices then help you master stress by helping you to pace your breathing, relax your muscles and think positive self-statements about your ability to cope. Studies show that these types of devices might be effective in improving responses during stress and inducing feelings of calm and well-being.
Another type of biofeedback therapy involves wearing a headband that monitors your brain activity while you meditate. It uses sounds to let you know when your mind is calm and when it's active to help you learn to control your stress response. The information from each session can be stored on your computer or mobile device so that you can track your progress over time.
The Food and Drug Administration (FDA) has approved a biofeedback device, Resperate, for reducing stress and lowering blood pressure. Resperate is a portable electronic device that promotes slow, deep breathing.
However, the FDA doesn't regulate many biofeedback devices marketed for home use. Before trying biofeedback therapy at home, discuss the types of devices with your care team to find the best fit.
Be aware that some products might be falsely marketed as biofeedback devices, and that not all biofeedback practitioners are legitimate.
Biofeedback, sometimes called biofeedback training, is used to help manage many physical and mental health issues, including:
Biofeedback appeals to people for a variety of reasons:
Biofeedback is generally safe, but it might not be appropriate for everyone. Biofeedback devices might not work properly on people with certain medical conditions, such as heart rhythm problems or certain skin conditions. Be sure to discuss it with your doctor first.
You don't need special preparation for biofeedback.
To find a biofeedback therapist, ask your doctor or another health care professional with knowledge of biofeedback therapy to recommend someone who has experience treating your condition. Many biofeedback practitioners are licensed in another area of health care, such as psychology, nursing or physical therapy.
State laws regulating biofeedback practitioners vary. Some biofeedback practitioners choose to become certified to show their extra training and experience in the practice.
Ask a biofeedback practitioner you're considering using questions before starting treatment, such as:
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.
If biofeedback is successful for you, it might help you control symptoms of your condition or reduce the amount of medication you take. Eventually, you can practice the biofeedback techniques you learn on your own. Don't stop the medical treatment for your condition, however, without consulting your care team.
