Summary

High-frame-rate video-oculography (VOG) shows promise for assessing vestibular-ocular reflex (VOR) gain. This mobile VOG device may allow for bedside testing of individual semicircular canal function.

Background:

Head impulses are a standard clinical bedside test for evaluating horizontal semicircular canal function.
Current methods like 3-D search-coil recording are necessary for assessing anterior and posterior canal function and vestibulo-ocular reflex (VOR) gain, but are not bedside-compatible.

Purpose of the Study:

To determine if video-oculography (VOG) can be used to assess VOR gain for individual semicircular canals at the bedside.
To evaluate the suitability of a mobile, high-frame-rate VOG device for bedside vestibular assessment.

Main Methods:

Healthy subjects underwent head impulse testing using a mobile, high-frame-rate, head-mounted VOG device.
VOG recordings were compared with data obtained from standard 3-D search-coil recording.

Main Results:

Preliminary results suggest that high-frame-rate VOG is a viable method for measuring VOR gain.
The study indicates potential for quantifying individual semicircular canal function using this bedside-compatible technology.

Conclusions:

High-frame-rate VOG is a promising tool for bedside assessment of semicircular canal function.
This technology may enable reliable measurement and quantification of VOR gain for individual canals outside of a laboratory setting.
