Overview of Biofeedback

When you raise your hand to wave hello to a friend, or lift your knee to take another step on the Stairmaster, you control these actions. Other body functions -- like heart rate, skin temperature, and blood pressure -- are controlled involuntarily by your nervous system. You don't think about making your heart beat faster. It just happens in response to your environment, like when you're nervous, excited, or exercising.

One technique can help you gain more control over these normally involuntary functions. It's called biofeedback, and the therapy is used to help prevent or treat conditions, including migraine headaches, chronic pain, incontinence, and high blood pressure.

Understanding Headache Treatment

Headache treatment depends largely on determining the cause of the headache. Tension headaches can usually be treated by the use of over-the counter pain relievers such as Tylenol, ibuprofen, or even aspirin. When tension or stress is the cause, nondrug options may include massage to relieve muscle tension, yoga and other forms of exercise, and working less when possible. The treatment of migraine headaches is somewhat more involved and may involve a number of different approaches to the pain....

The idea behind biofeedback is that, by harnessing the power of your mind and becoming aware of what's going on inside your body, you can gain more control over your health.

How Does Biofeedback Therapy Work?

Researchers aren't exactly sure how or why biofeedback works. They do know that biofeedback promotes relaxation, which can help relieve a number of conditions that are related to stress.

During a biofeedback session, electrodes are attached to your skin. Finger sensors can also be used. These electrodes/sensors send signals to a monitor, which displays a sound, flash of light, or image that represents your heart and breathing rate, blood pressure, skin temperature, sweating, or muscle activity.

When you're under stress, these functions change. Your heart rate speeds up, your muscles tighten, your blood pressure rises, you start to sweat, and your breathing quickens. You can see these stress responses as they happen on the monitor, and then get immediate feedback as you try to stop them. Biofeedback sessions are typically done in a therapist's office, but there are computer programs that connect the biofeedback sensor to your own computer.

A biofeedback therapist helps you practice relaxation exercises, which you fine-tune to control different body functions. For example, you might use a relaxation technique to turn down the brainwaves that activate when you have a headache.

Several different relaxation exercises are used in biofeedback therapy, including:

  • Deep breathing
  • Progressive muscle relaxation -- alternately tightening and then relaxing different muscle groups
  • Guided imagery -- concentrating on a specific image (such as the color and texture of an orange) to focus your mind and make you feel more relaxed
  • Mindfulness meditation -- focusing your thoughts and letting go of negative emotions
