Abstract
IntroductionMigraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life. Its association with vestibular symptoms is common, including imbalance and postural instability. ObjectiveTo evaluate the body balance of patients with vestibular migraine through a static posturography test. MethodsAn experimental group of 31 patients with a medical diagnosis of vestibular migraine in the intercritical period of the disease, and a control group of 31 healthy individuals, matched for age and gender, were submitted to the eight sensory conditions of the Tetrax Interactive Balance System. The parameters analyzed were: stability index, which measures the amount of sway, global stability and ability to compensate postural modifications; weight distribution index, which compares deviations in weight distribution; synchronization index, which measures the symmetry in the weight distribution; postural sway frequency, which indicates the frequency range with more sway; and fall risk index, which expresses the probability of falls. ResultsThe stability index was higher in the experimental group in all eight sensory conditions, with a significant difference between the groups in six of them. The weight distribution index was higher in the experimental group in all conditions, with a significant difference in three of them. The number of cases with preferential sway in F2–F4 was significantly higher in the experimental group in three conditions, and in F5–F6 in two, while the fall risk was significantly higher in the experimental group than in the control group. ConclusionPatients with vestibular migraine showed compromised body balance at the static posturography test.
Highlights
Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life
Vestibular migraine was identified in 4.2% of cases, and vestibular migraine was probable in 5.7% in a tertiary referral otorhinolaryngology clinic,[4] while a multicenter study in neurological clinics identified the prevalence of vestibular migraine as being 10.3% of migraine patients and probable migraine in 2.5%
The objective of this study is to evaluate the body balance of patients with vestibular migraine through static posturography
Summary
Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life. Objective: To evaluate the body balance of patients with vestibular migraine through a static posturography test. Migraine is a Greek term that means ‘‘half of the skull’’ It is known as migraine headache, which is one of the most frequent and incapacitating types of headaches, with a high degree of impairment in quality of life.[1] It is a primary head pain disorder, as it has no demonstrable cause in usual clinical or laboratory tests, occurs in recurrent episodes lasting from minutes to hours, is unilateral, pulsatile, of moderate or severe intensity, aggravated by physical activities and associated with nausea and/or photophobia and phonophobia.[2]. The prevalence of vestibular migraine is variable, according to the diagnostic criteria and the selected population.[4,5] It was estimated that the prevalence of vestibular migraine in the general population throughout life is approximately 1%.6 Using the recent criteria, vestibular migraine was identified in 4.2% of cases, and vestibular migraine was probable in 5.7% in a tertiary referral otorhinolaryngology clinic,[4] while a multicenter study in neurological clinics identified the prevalence of vestibular migraine as being 10.3% of migraine patients and probable migraine in 2.5%.7
