Vestibular Topodiagnosis Using the Vestibulospinal Pathway
摘要
The vestibular system contributes to perceptual, oculomotor, and postural functions. Clinical evaluation of vestibulospinal pathways can aid in diagnosing acute vestibular syndromes. Grade 3 truncal ataxia reliably indicates central pathology. Recent studies show that assessing gait and posture, even without nystagmus, helps differentiate central causes—especially in emergency settings where oculomotor expertise may be limited. Discrepancies between vestibulospinal and oculomotor signs have been observed in central lesions. This highlights the diagnostic value of vestibulospinal signs and supports further exploration of their pathophysiological mechanisms to enhance vestibular topodiagnosis.
