Neurodynamic responses in children with migraine or cervicogenic headache versus a control group. A comparative study.

Headache in children with unknown aetiology is an increasing phenomenon in industrial countries, especially during growth spurts. During this growth phase, the Long Sitting Slump (LSS) can be a useful tool for measurement of neurodynamics and management. This study investigated the difference in cervical flexion and sensory responses (intensity and location) during the LSS tests in children (n=123) aged 6-12 years, between a migraine (primary headache group=PG), cervicogenic headache (secondary headache group=SG) and control group (CG). The results indicated that the intensities of the sensory response rate were highest in the PG and SG when compared to CG. The responses in the legs were predominantly found in the PG (81.9%) and responses in the spine in the SG (80%). The sacrum position varied significantly between both headache groups (PG and SG) and the CG (p<0.0001), but there was no significant difference between the CG and the PG (p>0.05). No significant difference in the neck flexion range was measured in LSS, nor in standardized knee flexion between the PG and CG (p>0.05). The cervical flexion ranges differed significantly (p<0.0001) between the SG on the one hand and the PG and CG on the other. The biggest difference in neck flexion during knee extension was between the SG and CG.
