Pain Sensitivity Mediates The Relationship between Stress and Headache Intensity in Chronic Tension-Type Headache
Abstract
BACKGROUND: A central model for chronic tension-type headache (CTH) posits that stress contributes to headache, in part, by aggravating existing hyperalgesia in CTH sufferers. The prediction from this model that pain sensitivity mediates the relationship between stress and headache activity has not yet been examined.
