Bedside Smartphone‐Based <scp>vHIT</scp>

This study evaluated whether smartphone-based video head impulse testing (s-vHIT) can enhance bedside HIT in acute vestibular syndrome. Using a slow-motion smartphone recording setup, s-vHIT enabled visualization of overt and covert saccades, including vertical canal responses, with qualitative agreement with conventional vHIT. These findings indicate that s-vHIT may offer a practical and ergonomic approach for video documentation and may add diagnostic value in acute vestibular assessment.
