Biofeedback is a form of alternative medicine that involves measuring a subject's quantifiable bodily functions such as blood pressure, heart rate, skin temperature, sweat gland activity, and muscle tension, conveying the information to the patient in real-time. This raises the patient's awareness and conscious control of their unconscious physiological activities.

What is biofeedback?

Biofeedback is a technique in which people are trained to improve their health by learning to control certain internal bodily processes that normally occur involuntarily, such as heart rate blood pressure, muscle tension, and skin temperature.

These activities can be measured with electrodes and displayed on a monitor that both the participant and his or her practitioner can see. The monitor provides feedback to the participant about the internal workings of his or her body. This person can then be taught to use this information to gain control over these "involuntary" activities. Biofeedback is an effective therapy for many conditions, but it is primarily used to treat high blood pressure, tension headache, migraine headache, chronic pain, and urinary incontinence.
