Outcomes at 4 and 8 weeks.
| Outcome | Treatment group (n = 43) | Control group (n = 48) | p-value |
|---|---|---|---|
| DHI improvement rate at 4 weeks (%), mean ± SD | 56.2 ± 10.8 | 44.4 ± 11.8 | <0.001 |
| DHI improvement rate at 8 weeks (%), mean ± SD | 77.6 ± 6.34 | 66.9 ± 9.8 | <0.001 |
| RD duration (days), median (IQR) | 12 (7-18) | 19 (12-24) | 0.007 |
| Complete resolution of RD at 8 weeks, n (%) | 38 (88.4) | 33 (68.8) | 0.031 |
| MCID achievement (≥18-point improvement of DHI) at 4 weeks, n (%) | 24 (55.8) | 22 (45.8) | 0.397 |
| MCID achievement (≥18-point improvement of DHI) at 8 weeks, n (%) | 36 (83.7) | 30 (62.5) | 0.034 |
SD, standard deviation; RD, residual dizziness; IQR, interquartile range; DHI, dizziness handicap inventory; MCID, minimal clinically important difference. P values were calculated using an independent samples t-test for DHI improvement rates; Mann-Whitney U-test for RD duration, and chi-square test or Fisher’s exact test for categorical variables. p < 0.05 was considered significant.
