About the Lab
Professor Gi-Rak Kim's research lab specializes in clinical and translational vestibular neuroscience, focusing on the diagnosis and pathophysiology of acute audiovestibular syndromes, particularly in the context of posterior circulation strokes such as AICA infarction. The lab investigates the diagnostic utility of video head-impulse testing (video-HIT) in differentiating central vestibular disorders from peripheral conditions like labyrinthitis. A key research direction involves understanding the relationship between vestibular dysfunction and motor symptoms in neurodegenerative diseases, especially freezing of gait in early-to-moderate Parkinson’s disease. The lab integrates clinical neurology, vestibular physiology, and advanced neuroimaging to improve early detection and management of central vestibulopathy.

10Introduction Video head-impulse tests (video-HITs) often fail to detect anterior inferior cerebellar artery (AICA) infarction due to peripheral and central vestibular system involvement. Anecdotal studies suggest that video-HITs may reveal bilateral impairment in AICA infarction. However, the diagnostic utility of video-HITs has not been established, particularly when compared to labyrinthitis, which accounts for the majority of acute audiovestibular syndrome (AAVS) cases. Methods We reviewed th
Our preliminary data suggest that FOG is associated with the severity of motor symptoms in patients with early-to-moderate PD. While the integrity of the VOR or VSR is not currently associated with FOG, a well-designed future study could provide more nuanced insights into the relationship with these factors.
