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.
