Abstract

Biofeedback can be defined as the technique of using electronic equipment to reveal to human beings some of their internal physiological events, normal and abnormal, in the form of visual and auditory signals in order to teach them to manipulate these otherwise involuntary or unfelt events by manipulating the displayed signals. The use of electromyograph(EMG) and peripheral skin temperature are the prin- ciple modalities used today in clinical practice. Tension headaches or muscle contraction headaches in which the muscle groups or the head, neck and shoulders are involved to a great extent can be treated effectively with EMG biofeedback. Some migraine patients can be treated effectively with thermal biofeedback training. Biofeedback is a powerful therapeutic tool which teaches persons to take responsi- bility to learn self-regulation of themselves and their bodies. Korean Journal of Headache 4(1):41-47, 2003
