What is biofeedback?

Biofeedback is a technique that is used to train your mind to positively influence a variety of physiologic processes in the body, such as heart rate, blood pressure, and mental anxiety. It uses devices that provide direct and immediate feedback as people learn to consciously regulate body processes that are normally automatic. The National Center for Complementary and Alternative Medicine (NCCAM) categorizes biofeedback as a mind-body therapy, along with others, such as hypnosis, meditation, and guided imagery.

Can biofeedback help people with cancer?
Yes. Biofeedback has been shown to help patients reduce the severity and occurrence of headaches, anxiety, and chronic pain. It can also help relieve stress, muscle tension, and insomnia.

Biofeedback alone is not a proven treatment for cancer, nor has it been found to affect either cancer cells directly or the biology of an individual’s disease. It should not be used as a substitute for conventional care.

How does biofeedback work?
During biofeedback, a person is monitored with electrodes connected to electronic equipment that measures respiratory rate, perspiration, skin temperature, blood pressure, and heartbeat. A biofeedback technician recommends a variety of physical and mental exercises designed to teach a person how to relax and alter the functions being measured.

The results are displayed on a computer screen so the person can see the effects of their efforts in real time. Specific procedures or devices are used to measure each body change, including:

• Electromyogram (EMG) to measure muscle tension
  
• Electrodermal activity (EDA) to measure changes in perspiration rate
  
• Finger pulse devices to measure blood pressure and heartbeat

Biofeedback technicians in the United States are trained in the equipment, technology, and behavioral techniques used in this increasingly popular therapy, and can be nationally certified.

Are there any risks or complications associated with biofeedback?
No. There are no known side effects or problems associated with this therapy. As an addition to your cancer treatment plan, biofeedback has the potential to be pleasant and productive. It can enhance your sense of control and give you a meaningful, proactive way to participate in your care. However, as with other CAM therapies, always consult your physician for more information.
