Computerized dynamic posturography of patients with Migraine

Abstract

Recent studies have verified the presence of disorders related to static postural balance and agility in patients with Migraine, suggesting an altered dependence on the sensory systems that control the balance. However, neither the strategies nor the contribution of the visual, vestibular and proprioceptive systems on the balance of these individuals are known. Thus, the objective of this work will be to evaluate by dynamic computed postography the contribution of each of these components as well as the motor responses of the balance of patients with migraine with and without aura and control subjects. The volunteers will be screened from the HCFMRP Headache and Craniofacial Pain Outpatient Clinic and they will be submitted to two tests by a blind evaluator: 1) sensory organization test to evaluate the static balance in situations of stable and unstable support surface and mobile and fixed visual field; 2) motor control test, which measures the motor responses to abrupt and unexpected stimuli from the support base. It is expected that the data from this project elucidate the etiology of the reduction of postural control of patients with migraine, so that rehabilitation strategies can be incorporated in a targeted and effective way.
