    The study evaluated a portable video head impulse testing (vHIT) system using an iPod touch and a custom 3D-printed oral stabilization mount.

  • 2

    Thirteen patients with unilateral vestibular hypofunction and 14 healthy volunteers were tested with both portable and medical-grade vHIT systems.

  • 3

    The portable vHIT system detected laterality in unilateral vestibular hypofunction and met noninferiority criteria compared to the medical-grade device.

  • 4

    Mean laterality difference was 0.518 for the medical device and 0.453 for the portable system, with a between-device difference of -0.065.

  • 5

    Abnormal classifications occurred in 7.1% of ears and 14.3% of participants with the portable system, compared to 0% with the medical-grade device.
