Biofeedback is on the verge of becoming an important tool in medical therapy. Using biofeedback, a patient can learn to control certain body systems, such as heartbeat, temperature, or blood pressure, that are normally autonomic or self-regulating. The patient is attached 5 to a machine measuring the function he wishes to control. When the desired result is achieved, the patient hears a steady tone that indicates that the patient has successfully manipulated that body function to a more desirable state. For example, if a patient wishes to learn to control his heartbeat, he is attached to a biofeedback 10 machine monitoring his heartbeat. When the patient manages to successfully slow his heart beat, the biofeedback machine rewards him with a low, dull noise. Today researchers are using biofeedback to treat patients with such maladies as irregular heartbeat, migraine headaches, and high blood pressure. The medical community foresees myriad applications 15 that may be treated with biofeedback in the future.
