To rule out the presence of peripheral vestibular deficit, participants underwent VOR assessment via video head impulse test, or via other VOR assessment techniques appropriate for the patient’s clinical findings (e.g. bithermal caloric irrigation or electronystagmography with rotational chair testing was performed if a video head impulse test was not possible due to neck injury). The assessment was performed according to the standard clinical procedures of the Vestibular Neurology laboratory (Charing Cross Hospital, Imperial College London NHS Trust). L = left; LC = left canal; R = right; RC = right canal; SPV = slow phase velocity; vHIT = video head impulse test. A dash indicates where the test was not completed, or adequate recordings obtained.
