Why biofeedback would help this problem:Tension headaches are usually caused by muscles in the neck, shoulders, jaws and other facial structures being kept too tense for too long. These muscles may become too tense because some people can not recognize the actual level of tension in painful muscles, because of postural problems while working, over-reactions by the muscles to stress, poor habits, etc. Psychophysiological assessments can identify which muscles are not functioning correctly and what circumstances lead to the incorrect patterns of tension. Biofeedback of muscle tension is used to train people to recognize actual levels of tension and to correct these levels in conjunction with relaxation training. Temperature biofeedback for migraine headaches work through a similar chain of logic.
