Muscle tenderness in pericranial and neck-shoulder region in children with headache. A controlled study.

Abstract

Increased pericranial muscle tenderness is connected with tension-type headache in adults. In children, the importance of muscle tenderness in the pericranial or neck-shoulder region in the pathogenesis of different types of headache is unknown. The present study evaluated muscle tenderness in the pericranial and neck-shoulder region in children with migraine, those with tension-type headache and those without headache. An unselected population-based questionnaire study concerning headache was carried out in 1135 Finnish schoolchildren aged 12 years. Of them, 183 children were randomly selected for a face-to-face interview and a clinical examination. Muscle tenderness was recorded by manual palpation and dolorimeter. Children with migraine had increased overall tenderness, recorded by manual palpation, compared with those without headache. They also self-reported tenderness in the neck-shoulder region during daily activities more often than the children of the other groups. Muscle tenderness was not associated with paediatric tension-type headache. The mean pressure pain thresholds did not differ among the three groups. However, a negative correlation between the total tenderness score and the dolorimeter score was found in each group. In conclusion, children with migraine had increased muscle tenderness at palpation of the pericranial and neck-shoulder muscles and they also reported pain symptoms in the neck-shoulder region most frequently. Instead, increased pericranial and neck-shoulder muscle tenderness was not associated with tension-type headache in children.
