Headache Characteristics in Patients with Tension-Type Headache in Relationship to Pericranial Muscle Pain Sensitivity

AIM: Categorizing of tension-type headache according to the IHS classification as forms with normal and forms with increased percranial muscle tenderness appears useful if by implementing this criterion either etiopathogenetic, clinically phenomenological or therapeutic characteristics between the two forms can be inferred. We investigated whether healthy subjects (N=29), patients with migraine (N=23), and patients with tension-type headache (N=20) differ in terms of their pericranial pain sensitivity. Furthermore we asked whether differences in clinical headache pain phenomenology were evident within the group of patients with tension-type headache in relationship to pericranial muscle pain sensitivity.
