“…In contrast, we found no significant group differences regarding heart rate changes during active standing. At tilting, however, which reduces the influence of the muscle pump and of motor activity in general (63–65), we found Ewing ratio increased in migraine patients. Tilting was not studied by Yakinci et al (33).…”

“…During orthostatic tests venous return and cardiac output are reduced, which induces vasoconstriction and increased heart rate maintaining arterial pressure (63,64). In addition to the gravitational volume shifts at tilting, standing induces direct changes of muscle vessels and autonomic changes connected with muscular activity (63)(64)(65). Static exercise is accompanied by an increase in blood pressure and heart rate caused by central command and above all by the activation of muscular 'labour' receptors (63,97).…”

To investigate autonomic regulation in juvenile migraine we studied 70 children and adolescents with migraine during the headache-free period and 81 healthy controls by cardiorespiratory function tests. Heart rate variability was analysed with time and frequency domain indices during spontaneous breathing at rest and during metronomic breathing. Changes of heart rate and blood pressure were studied during tilt-table test, active standing, Valsalva manoeuvre and sustained handgrip. We found significant differences in metronomic breathing, tilt-table test and Valsalva manoeuvre. We interpret our findings and results reported in the literature as pointing to a restricted ability of the system to rest, which supports therapies intending to further this ability. In autonomic tests, hyperreactivity in juvenile migraineurs changes to hyporeactivity and passive coping in adults. This might be explained by disturbances of raphe nuclei and the periaqueductal grey. It corresponds to psychological findings in juvenile migraineurs reporting hypersensitivity and repressed aggression and claiming learned helplessness.
