The pathophysiological mechanisms underlying chronic tension-type headache are still unclear. The aim of the present study was to investigate tenderness of pericranial muscles by examining pressure pain thresholds in adolescents suffering from chronic tension-type headache. A group of 35 patients with chronic tension-type headache was compared to 70 healthy controls in terms of pressure pain thresholds. A conventional hand-held algometer was used to measure the pressure pain thresholds in the upper trapezius, suboccipitalis, and frontalis muscles. Pressure pain thresholds were significantly lower in patients than in healthy controls. Pressure pain threshold values of bilateral trapezius muscles were significantly negatively correlated with the pain intensity. There was no correlation between the pressure pain threshold values and duration, or frequency of headache. Along with results obtained previously, the present data support the hypothesis that muscular factors may be an important factor for the pathophysiology of chronic tension-type headache. © 2005 VSP.
