AbstractMigraine is a chronic disabling disorder, with migraine episodes significantly reducing quality of life and leading to impaired functioning (physically, socially, emotionally) both at home and at work. We explored whether ambulatory accelerometry can be used as an objective method to quantify the behavioral aspects of migraine-related disability. Four body mounted uni-axial piezo-resistive accelerometers were used to quantify the time spent in different body postures (lying, sitting, standing), physical activities (walking, cycling) and a general index of body motility during eight migraine attacks and subsequent recovery periods of six patients in their habitual environment. The migraine attacks and recovery periods could be monitored after about 1 h, which was the time required for the investigator to travel to the patient and for the sensors to be attached. In order to quantify the influence of a migraine episode on daily activities, we also performed measurements during a headache-free baseline period of the same patients. Overall, the procedures functioned well, indicating that ambulatory accelerometry measurements before, during and after a migraine attack are feasible to perform. Furthermore, our quantitative data revealed that migraine always influenced behavior by reducing overall body motility and that, dependent upon the severity of the attack, the effectiveness of acute treatment and the time of day, the time spent in various body positions, dynamic activities, and the number of postural transitions were affected. This feasibility study showed that ambulatory accelerometry can provide the objective behavioral effect parameters for the evaluation of migraine and its treatment on daily functioning in the habitual environment of migraine patients.
