Long-term follow-up of migraine treatment: do the effects remain up to six years?

Fifty migraine subjects (constituting 79% of the originally treated sample) participated in a follow-up study to 6 yr after the end of treatment. Subjects had been treated with different forms of biofeedback methods (skin temperature, BVP of the temporal artery) and applied relaxation training. The assessment included 4 weeks of continuous self-monitoring of headache activity and medication usage, as well as a retrospective self-rating scale. The main results indicated that, on a group basis, headache reductions achieved at the end of treatment persisted for up to 6 yr, and were indeed enhanced during the follow-up period.
