The Headache Classification Committee of the International Headache Society recently issued revised diagnostic criteria for headache disorders. According to these criteria, tension-type headache may be subclassified depending upon whether pericranial muscle disorder is found. The presence or absence of pericranial muscle disorder was to be determined by palpating the muscles for tenderness or by measuring electromyographic (EMG) activity. In this study, pericranial muscles were palpated, and EMG activity was measured in 27 episodic tension-type headache patients and 32 headache-free controls. All testing was done while the subjects were in a headache-free state. Muscle tenderness was positively associated with the diagnosis of tension-type headache. Headache subjects exhibited significantly higher levels of temporal EMG activity compared to controls, but EMG data were of little use in assigning individual subjects to diagnostic groups. Measures of muscle tenderness and hyperactivity were only weakly associated. Pericranial muscle tenderness and elevated EMG activity may index different aspects of abnormal muscle function.

Thirty patients with whiplash injuries were examined 1 to 55 months after the accidents. Pain had appeared on the day of the accident in 24 (80%) of the patients and with different delays in the remainder. The mean pain intensity was 43 mm (SD 26) on a visual analogue scale (VAS). All patients had pain in the neck, 17-33% had headache and 6-17% had pain in various regions of the arms. Thirteen patients (43%) suffered from constant pain, while 17 (57%) had pain-free periods. Muscle tenderness was higher at all tested sites compared with controls. The tolerance level to pressure pain in the index finger as well as grip strength and neck mobility was reduced compared with controls. The whiplash patients showed poorer mental well-being compared with a reference group representing the general population and compared with a group of tension-type headache patients.

The present study examined the associations between craniofacial dimensions, head posture, bite force, and symptoms and signs of temporomandibular disorders (TMD). The sample comprised 96 children (51F, 45M) aged 7-13 years, sequentially admitted for orthodontic treatment of malocclusions entailing health risks. Symptoms and signs of TMD were assessed by 37 variables describing the occurrence of headache and facial pain, clicking, jaw mobility, tenderness of muscles and joints, and the Helkimo Anamnestic and Dysfunction indices. Craniofacial dimensions (33 variables), and head and cervical posture (nine variables) were recorded from lateral cephalometric radiographs taken with the subject standing with the head in a standardized posture (mirror position). Dental arch widths were measured on plaster casts and bite force was measured at the first molars on each side by means of a pressure transducer. Associations were assessed by Spearman correlations and multiple stepwise logistic regression analyses. The magnitudes of the significant associations were generally low to moderate. On average, temporomandibular joint (TMJ) dysfunction was seen in connection with a marked forward inclination of the upper cervical spine and an increased craniocervical angulation, but no firm conclusion could be made regarding any particular craniofacial morphology in children with symptoms and signs of TMJ dysfunction. Muscle tenderness was associated with a 'long face' type of craniofacial morphology and a lower bite force. Headache was associated with a larger maxillary length and increased maxillary prognathism. A high score on Helkimo's Clinical Dysfunction Index was associated with smaller values of a number of vertical, horizontal, and transversal linear craniofacial dimensions and a lower bite force.

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.
