Are signs of temporomandibular disorders stable and predictable in adolescents with headache?

The aim of the present study was to study changes in signs and symptoms of temporomandibular disorders (TMD) and factors predicting TMD signs in adolescents with and without headache. A population-based sample (n = 212) of 13-year-olds with and without headache was re-examined at the age of 16. The study included a questionnaire, face-to-face interview and somatic examination. In addition, a neurological examination, a muscle evaluation and a stomatognathic examination were performed. Significant changes were seen in TMD signs during the follow-up, but TMD signs at the end of the follow-up could not be predicted by baseline headache, sleeping difficulties, depression or muscle pain. TMD signs at the age of 16 were associated with female gender and muscle pain. We conclude that considerable changes in TMD signs occur in the follow-up of adolescents with and without headache. Headache-related TMD are not predictable in adolescents with and without headache.

Headache children with temporomandibular disorders have several types of pain and other symptoms.

The aim was to investigate the association between temporomandibular disorders (TMD) and overall muscle tenderness, depressive symptoms, sleep difficulties, headache frequency and related symptoms in children with primary headache in comparison with controls. Based on an unselected population sample of 1135 Finnish schoolchildren classified according to the type of headache at age 12, altogether 297 children aged 13-14 from different headache groups and healthy controls were randomly selected for an interview and clinical examinations. Children with migraine had more TMD signs than children with nonmigrainous headaches or healthy controls. High TMD total scores were associated with palpation tenderness in other parts of the body and with frequent headache attacks. We conclude that children with overall headache, migraine in particular, and high total TMD scores showed an increased overall tenderness to muscle palpation and multiply manifested hypersensitivity pain.

Leisure activities in adolescents with headache.

AIM: To investigate the association between different types of headache and leisure activities in 13-y-old schoolchildren. METHODS: A population-based, cross-sectional study was performed through face-to-face interviews with age-matched cohorts with headache and asymptomatic controls. The present study comprised 59 children with migraine, 65 with episodic tension-type headache (TTHA) and 59 headache-free controls. In the interview, besides questions concerning headache, the children were asked open and structured questions about the type and amount of their leisure activities. RESULTS: Children with migraine spent more time in sports activities than children with episodic tension-type headache or children without headache (test for trend, p<0.01; migraine: OR 1.4, 95% CI 1.1-1.9; tension-type headache: OR 0.9, 95% CI 0.7-1.1). The type of leisure activity was not significantly associated with headache type (p>0.05). Children with both migraine and episodic tension-type headache used computers more often than children without headache (test for trend, p<0.05; migraine: OR 1.2, 95% CI 1.1-1.5; tension-type headache: OR 1.3, 95% CI 1.1-1.5). CONCLUSION: This study provides additional data on the activity status and headache complaints in adolescents. The results indicate that frequent computer use is associated with both tension-type headache and migraine, and intensive overall sports activities are characteristic of adolescents with migraine.

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

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.
