Characteristics of the two vestibular migraine subgroups (VM1, VM2) identified in Fig. 3B (VOR time constant versus tilt threshold).
| Clinical measure | VM1 | VM2 | Statistical comparisons |
|---|---|---|---|
| VOR time constant (sec) | 15.5 +/− 0.7 | 18.8 +/− 1.7 | M-W RST: p = 0.2 |
| MSSQ | 26.4 +/− 4.6 | 22.7 +/− 5.4 | t-test: p = 0.6 |
| HIT | 56.9 +/− 2.2 | 51 +/− 5.9 | M-W RST: p = 0.7 |
| Age (years) | 39.4 +/− 2.7 | 34.5 +/− 4.5 | t-test: p = 0.35 |
| Sex (F:M) | 9 F:2 M | 9 F:1 M | Rank test: p = 0.6 |
| *Roll tilt threshold (deg) | 1.83 +/− 0.15 | 0.97 +/− 0.5 | M-W RST: p < 0.001 |
