Anxiety levels, heart-rate and heart-rate variability measures in patients with BPPV in comparison with healthy controls.
| Patients with BPPV (N = 18) | Healthy controls (N = 18) | p-value | |
|---|---|---|---|
| Anxiety levels | |||
| Total STAI score (/160) | 68 [45–102] | 62 [44–94] | 0.09 |
| State anxiety sub-score (/80)1 | 34 [20–67] | 24 [20–43] | <0.01 |
| Trait anxiety sub-score (/80)1 | 33 [23–53] | 39 [24–54] | 0.52 |
| Heart-rate and heart-rate variability | |||
| Average heart-rate (beats per minute)2 | 71.6 ± 12.2 | 69.5 ± 8.5 | 0.55 |
| SDNN (milliseconds)2 | 53.0 ± 29.6 | 58.4 ± 21.4 | 0.53 |
BPPV-Benign paroxysmal positional vertigo; STAI-State Trait Anxiety Inventory; SDNN-Standard deviation of the normal-to-normal intervals; 1Ordinal scale variables are shown as median [minimum - maximum], p-values calculated with Mann–Whitney test; 2Ratio scale variables are shown as mean ± SD, p-values calculated with Student’s T-test.
