Evaluation of vestibular and oculomotor functions in individuals with dizziness after stroke

Abstract

Changes in postural balance and visual complaints are frequent consequences of stroke. We aimed to investigate the symptoms and the vestibular and oculomotor functions of patients with dizziness post ischemic and hemorrhagic stroke and compare the results among them. Methods: Fifty patients with dizziness after stroke were evaluated through a clinical anamnesis and computerized vector electronystagmography: calibration of ocular movements, spontaneous nystagmus, semi-spontaneous nystagmus, pendular tracking, optokinetic nystagmus, rotary chair testing, and the caloric test. Results: All patients complained of dizziness, especially imbalance. Ischemic stroke in the carotid territory was the prevalent type. Visual complaints were reported by 56% of the sample and were related to abnormalities in oculomotor and caloric tests. Conclusion: The occurrence of visual symptoms was related to some abnormalities in the vector electronystagmography tests, being more frequent in cases of stroke in the vertebrobasilar system, and with oscillopsia and reduced visual acuity as symptoms.

Hearing loss, gait and balance impairments and falls among individuals with sub-acute stroke: A comparative cross-sectional study

“…It has also been postulated that auditory problems may extend to vestibular organs due to the proximity of cochlear and vestibular sense organs in the inner ear (bony labyrinth) [ 39 ], and thus affect balance and gait. Balance and gait are maintained by the complex integration and coordination of several body systems including the visual, motor, higher-level premotor, vestibular and auditory systems [ 40 ]. The hearing system is responsible for the integration of information on movement and positions of the head and body to the brainstem, cerebellum and somatosensory cortex to maintain balance [ 40 ].…”

“…Além disso, o Brasil nas últimas décadas tem se deslumbrado com a evolução do capitalismo e da globalização, condições importantes para a economia nacional, mas que configuram em um padrão cultural inadequado para a manutenção da saúde pelo fato de que isso proporciona o aumento do sedentarismo e do consumo de "fast food", comportamentos que facilitam a ocorrência dessa perturbação patológica (PIMENTEL;FILHA, 2019).
