Abstract:
The specificity and efficacy of a short EMG biofeedback treatment were assessed in a selected group of chronic tension-headache cases—those having significantly elevated levels of muscle tension. The effects of training patients to raise/maintain EMG levels were compared to those obtained from patients who were trained to lower tension levels. The results showed little evidence of increased self-control of the muscle despite successful EMG control during six bio-feedback sessions. A progressive and significant reduction in resting level was found only in the groups trained to reduce EMG levels. The treatment proved ineffectual in reducing headache. The implications of the dissociation of muscle tension and headache are discussed both with respect to current views of tension headaches and the role of biofeedback in their treatment.
