Highlights
- •AVS requires a rapid and accurate evaluation to determine its etiology.
- •Truncal ataxia is shown as a sign that is easy to evaluate and very useful in the etiological diagnosis of AVS.
- •For those cases in which the patient cannot stand, assessing the incubitus truncal ataxiais a good substitute for truncal ataxia.
Abstract
Introduction and objectives
acute vestibular syndrome is a diagnostic challenge, requiring a rapid and precise
diagnosis to take therapeutic actions. Truncal ataxia, inability to sit still, and
Babinski flexor dysergy were evaluated. Material anf methods: 52 patients with central
pathology (stroke in aica and pica territory) and vestibular neuritis were prospectively
studied. MRI of the brain was used as the gold standard.
Results
A combination of grade 2–3 ataxia to differentiate patients with vestibular neuritis
from patients with stroke resulted in a 92% sensitivity (95% CI 79–100%), a 67% specificity
(95% CI 47–86%). Flexion asynergy had a 70% sensitivity (95% CI 47–92%), and an 88%
specificity (95% CI 69–100%). The inability to sit still correlated well with truncal
ataxia.
Conclusions
vestibulospinal signs are useful in the differential diagnosis of acute vestibular
syndromes, and the inability to sit is a good substitute for truncal ataxia when it
cannot be evaluated.
