In addition, an increase of symmetry of condylar movements after therapy has been associated with a decrease of activation magnitude in primary motor and cerebellar regions.

In order to minimize recall bias in burden estimation, questions about headache yesterday were included in a population-based survey initiated by LIFTING THE BURDEN : The Global Campaign against Headache. ⋯ Of the adult Chinese population, 1.8% have headache at any one time that is of moderate to severe intensity in 1.4%, and 1.3% lose the equivalent of a whole day to headache-attributed disability every day. In China this means 12.3 million people.
