Both guided imagery groups had significantly more improvement than the controls in three of the outcome measures: headache intensity, headache frequency and headache duration. There were no other significant differences between the guided imagery groups (tape and perceived happy memory) at any time point.
The investigators conclude that guided imagery is an effective, available and affordable non-pharmacological therapy for the management of chronic tension headaches, either with a recording or with self-generated exercises of re-experiencing a happy memory without a recording.
