Key findings
In the present study we evaluated a clinically applicable screening test for VS in patients with ASNHL, a highly prevalent clinical condition.
We identified a significantly lower mean VOR on the affected side for vHIT test in the VS group. An analysis of saccade velocity or latency in the present study revealed high specificity (87 and 91%, respectively) but low sensitivity (51%).
When we categorized the presence of the VIN with mastoid stimulation, we yielded sensitivities of 81.8% and specificities of 73.9%.
