Pericranial muscle tenderness and pressure-pain threshold in the temporal region during common migraine.

Author information

Department of Neurology, Gentofte Hospital, University of Copenhagen, Hellerup, Denmark.


Twenty-six patients were examined during attacks of common migraine as well as during headache-free interval. Pericranial tenderness was scored blindly by a systematic manual palpation on both occasions by the same observer. Pressure-pain threshold (PPT) in a fixed location over the temporal muscle was determined by the use of a pressure algometer. A 28% increase in total tenderness score was observed during attacks (P less than 0.01). During unilateral attacks, tenderness scores were significantly higher on the ipsilateral side as compared to the contralateral (P less than 0.01). A positive correlation was observed between tenderness on the two sides (P less than 0.05) and the two occasions (P less than 0.01). PPT showed no changes during migraine attacks and there was no difference in PPT between the ipsilateral and contralateral side. A positive correlation was observed between PPT on the two sides and the two occasions (P less than 0.01). PPT was not correlated to the tenderness scores obtained by manual palpation. The absence of a decrease in PPT and the presence of several tender areas in multiple regions, particularly where pain was spontaneously reported to be located, suggest the presence of either a multi-focal peripheral pathological process or referred pain from other structures in the head and neck region.
