The use of EEG theata biofeedback in the treatment of a patient with sleep-onset insomnia

In this report, the treatment of a 42-year-old female with a complaint of chronic sleep-onset insomnia is described. Following the unsuccessful use of relaxation training, treatment consisted of 11 sessions of EEG theta rhythm (4–7 Hz) biofeedback. Theta density and five sleep indices were monitored throughout baseline, placebo, and treatment sessions. A significant increase in theta density was accompanied by reports of a decrease in sleep latency and an increase in total sleep time. This improvement was maintained after withdrawal of medication and at 3-month follow-up.Appreciation is expressed to Dr. R. Muir, for medical supervision of the patient, and to Mr. D. F. Peck and Dr. J. I. Evans, for their comments on earlier drafts of this paper.
