“…In noncontrast MRI, different imaging sequences can be used to obtain contrasting images of clear and dark blood, providing valuable diagnostic information from different perspectives. In MR angiography, blood flow interferes with MR signals [ 17 ]. To avoid this effect, a new gradient waveform, commonly referred to as a velocity compensation technique, had to be developed.…”

Cervical vertigo refers to a clinical syndrome with sudden vertigo as the main symptom caused by the hemodynamic disturbance of the extracranial segment of the vertebral artery (VA) affected by cervical vertebral lesions. Small differences in pulse intervals in a patient’s continuous sinus rhythm are called heart rate variability (HRV). Heart rate variability refers to the small rise and fall of instantaneous heart rate between consecutive beats and is one of the most important physiological indicators of cardiac function. Small changes between successive beats reflect some information about the heart. So, it can be used to diagnose heart disease; its parameters can be used to identify emotions. Therefore, it is possible to use the characteristics of heart rate variability to find some patterns in the high-stress state and use the computer and ECG signals to describe the high-stress state. Since the ECG signal is a universal and objective model, it is practical and convenient to use it to describe stress states. Magnetic resonance angiography (MR angiography, MRA) is a noninvasive vascular imaging method that does not require intubation and contrast agents. At present, it has been widely used in clinical practice. In order to explore the changes of short-term heart rate variability and vertebral arterial magnetic resonance angiography (MRA) in patients with cervical vertigo and their clinical significance, this paper introduces two basic analysis methods of heart rate variability and commonly used MRA techniques, TOF technology. In the analysis of heart rate variability in patients with cervical vertigo, the statistical values of time and spectrum domain parameters were found to be lower in the experimental group than in the control group1. MRA showed that the abnormal rate of VA in the PCI group and the cervical vertigo group was similar. In the RMSSD index, the male experimental group reached 29, and the control group 1 reached 22.

“…Poucas pesquisas estudaram as alterações na posturografia nas diferentes causas de tontura. Autores (23) mostraram resultados diferentes entre as vertigens de origem central e mista. Tanto os sistemas sensoriais (visual, somatossensorial e vestibular), quanto o motor e o processamento central podem sofrer alterações…”

“…Nesse sentido, alguns estudos já mostraram que indivíduos idosos saudáveis com história de quedas apresentam menos capacidade de compensar os desafios gerais do equilíbrio (9,14,15) , sugerindo que o uso da posturografia poderia verificar alterações no sistema vestíbulo-espinal e avaliar a diminuição do controle postural com o envelhecimento (9,13,(16)(17)(18)(19)(20)(21)(22)(23) .…”

RESUMO Objetivo avaliar se a posturografia, exame que avalia a habilidade de manter o equilíbrio em condições sensoriais conflitantes, pode identificar risco de queda em idosos com tontura. Métodos comparar os resultados posturográficos de idosos com e sem história de quedas, pareados por gênero, idade e diagnóstico etiológico da tontura. Resultados dezoito idosos com quedas – 4 com único episódio e 14 com história de 2 ou mais quedas no último ano - foram comparados com 18 idosos sem quedas, pareados por gênero, idade e diagnóstico etiológico. Pacientes com quedas apresentaram resultados piores para as análises de dependência visual (p=0,04, p=0,01, p=0,03). Pacientes com quedas recorrentes (2 ou mais episódios) apresentaram piores resultados em diversas condições sensoriais: somatossensorial, vestibular, dependências visuais e índice de equilíbrio composto. Conclusão a posturografia mostrou-se útil na identificação de idosos com quedas, principalmente em indivíduos com quadros recorrentes.

“…Sekitar 7-10% vertigo yang dialami ini bersifat rekuren. Vertigo juga dapat dialami oleh anak-anak dengan prevalensi 8-18% (5). Pada penelitian yang dilakukan di tahun 2015 di Amerika, insidensi dari vertigo berkisar di angka 3.1% di mana prevalensinya sebesar 22.9% (1).…”

Central vertigo is a symptom characterized by a feeling of changes in body position or environment as a result of diseases originating from the central nervous system. Central vertigo is caused by a disease that extend from vestibular nuclei in medulla oblongata to ocular motor nuclei and integration system in mesencephalon to vestibulocerebellum, thalamus and vestibular cortex in temporoparietal and the neuronal pathway which mediate VOR (vestibulo-ocular reflex). The diseases can be vestibular migrain, TIA (Transient Ischemic Attack), Vertebrobasilar ischemic stroke, multiple sclerosis, tumor in cerebelopontine angle and congenital malformation like Dandy Walker Syndrome. Central vertigo can be diagnosed by performing several special tests. This examination can also distinguish central vertigo from its differential diagnosis, namely peripheral vertigo. Management of central vertigo can be in the form of acute attack management and specific management according to the cause.

Posturography studies in patients with central and mixed vertigo Summary

Abstract: Based on the conducted research, it may be concluded that the ability to keep balance in subjects with central and mixed vertigo is on average three times lower than in population not suffering from vertigo episodes.
