Dynamic visual acuity during head-thrust test in canal planes in healthy subjects and patients with vestibular neuritis.

Conclusions: Dynamic visual acuity (DVA) during the head-thrust test (htDVA) is reliable in normal subjects, having a high specificity for the horizontal canal, so it may be useful to monitor vestibular rehabilitation in patients with vestibular neuritis (VN).

Objective: To obtain reference values for htDVA in healthy individuals and to investigate the potential application in subjects with unilateral VN.

Methods: A total of 73 healthy individuals and 50 patients with unilateral VN were included.
