Biofeedback
Biofeedback uses electronic sensors to monitor body functions such as muscle tension, skin temperature, heart rate, and blood pressure. Data are fed back to the patient through sounds or computer images. The goal is to teach people how to control bodily responses—easing tight muscles, for example—to prevent headache pain.
Studies show biofeedback could be effective for migraine and tension-type headache. A recent analysis published in Headache suggests behavioral therapies, such as biofeedback, are more cost-effective over time than prescription drugs.
