Restricted neck mobility in children with chronic tension type headache: a blinded, controlled study.
The main purpose of this study was to analyze the differences in neck mobility between children with chronic tension type headache (CTTH) and healthy children, and to determine the influence of cervical mobility on headache intensity, frequency and duration. Fifty children, 13 boys and 37 girls (mean age 8.5 ± 1.6 years) with CTTH associated to peri-cranial tenderness (IHS 2.3.1) and 50 age- and sex matched children without headache (13 boys, 37 girls, mean age 8.5 ± 1.8 years, P = 0.955) participated. Cervical range of motion (CROM) was objectively assessed with a cervical goniometer by an assessor blinded to the children's condition. Children completed a headache diary for 4 weeks to confirm the diagnosis. Children with CTTH showed decreased CROM as compared to children without headache for flexion (z = -6.170; P < 0.001), extension (z = -4.230; P < 0.001), right (z = -4.505; P < 0.001) and left (z = -4.768; P < 0.001) lateral-flexions, but not for rotation (right z = -0.802; P = 0.425; left z = -1.254; P = 0.213) and also for total range of motion for flexion-extension (z = -4.267; P < 0.001) and lateral-flexion (z = -4.801; P < 0.001), but not for rotation (z = -1.058; P = 0.293). Within CTTH children, CROM was not correlated with headache intensity, frequency or duration. Additionally, age (P > 0.125) or gender (P > 0.250) did not influence CROM in either children with CTTH or without headache. Current results support the hypothesis that the cervical spine should be explored in children with headache. Further research is also needed to clearly define the potential role of the cervical spine in the genesis or maintenance of CTTH.
