Summary of studies investigating the impact of episodic vertigo on perceptual thresholds.
| Study | Subjects | Stimuli | Findings |
|---|---|---|---|
| Bremova et al. (37) | • 27 Meniere's disease (mean age: 58) • 20 vestibular migraine (mean age: 40.9) • 34 healthy controls (mean age: 44.6) |
Raised cosine velocity profile | • Z-translation (1 Hz), and x-translation (1 Hz) thresholds were significantly higher in MD in comparison to both VM and healthy controls. • Y-translation (1 Hz) thresholds were significantly higher in MD in comparison to VM, but not significantly different in comparison to healthy controls. |
| King et al. (63) | • 12 vestibular migraine (35.5 ± 2.7 years) • 12 migraine (34.0 ± 3.1 years) • 12 healthy control (38.1 ± 3.1 years) • 8 Meniere's disease |
Single cycle of sinusoidal acceleration | • Roll tilt thresholds were significantly lower in VM patients in comparison to healthy controls, migraine (0.03, 0.05, 0.1 Hz) and MD (0.2 Hz); no differences were seen at higher frequencies (0.2, 0.5, 1, 2, 5 Hz). • Y-translation (0.2, 0.3, and 0.5 Hz) and roll rotation (0.2 and 0.5 Hz) thresholds not significantly different between VM, migraine, and healthy controls. |
| Lewis et al. (53, 54) | • 8 vestibular migraine (35.5 ± 2.7 years) • 8 migraine (34.0 ± 3.1 years) • 8 healthy control (38.1 ± 3.1 years) |
Single cycle of sinusoidal acceleration | • Roll tilt thresholds (0.1 Hz) were significantly lower in VM in comparison to migraine and healthy controls. • Quasi-static roll tilt (constant ramp of 0.125 deg/s) and roll-rotation thresholds (0.1 and 1 Hz) were not significantly different between patients with VM and healthy controls. |
| Bednarcazuk et al. (42) | • 15 vestibular migraine (mean age, 42.0) • 15 migraine (mean age: 38.7) • 15 BPPV (mean age: 44.7) • 15 healthy controls (mean age: 44.7) |
Acceleration at 0.3 deg/s/s, increasing by 0.3 deg/s/s every 3 s | • Yaw rotation thresholds were significantly higher in VM and BPPV in comparison to patients with migraine and healthy controls. |
BPPV, benign paroxysmal positional vertigo; HIT, head impulse test; MD, Meniere's Disease; VM, vestibular migraine; VN, vestibular neuritis.
