Table 2.
vHIT results in unilateral vestibular neuritis patients with normal to mild dizziness and moderate to severe dizziness at the follow-up (n = 47).
| Normal to mild dizziness (DHI ≤30; n = 28) | Moderate to severe dizziness (DHI > 30; n = 19) | p-value | |
|---|---|---|---|
| Normal vHIT gain (%) | 57.14(16/28) | 21.05(4/19) | <0.05b |
| Lesion-side mean gain | 0.77 ± 0.25 | 0.62 ± 0.19 | <0.05a |
| Without saccade (%) | 21.42(6/28) | 0(0/19) | 0.06c |
| Occurrence of isolated covert saccade (%) | 39.29(11/28) | 10.53(2/19) | <0.05b |
| Occurrence of mixed saccade (%) | 39.29(11/28) | 89.47(17/19) | <0.01b |
| Velocity of overt saccade (°/s) | 155.10 ± 33.60 | 160.52 ± 30.94 | >0.05a |
| Latency of overt saccade (ms) | 308.93 ± 46.84 | 306.97 ± 30.96 | >0.05a |
| Velocity of covert saccade (°/s) | 170.41 ± 45.15 | 201.10 ± 40.46 | <0.05a |
| Latency of covert saccade (ms) | 124.85 ± 27.21 | 123.43 ± 22.45 | >0.05a |
