Table II.
Age at diagnosis, last episode duration since the onset of symptomatology, overall number of crisis and vertigo intensity in relation to the final outcome of a single SM performed due to posterior BPPV. Differences resulted not significant at the ANOVA test (p > 0.05).
| Age (a) |
Last episode duration (b) |
Overall number of crisis | Vertigo intensity (c) |
|
|---|---|---|---|---|
| Persistence of disease (n = 24) | 65 ± 9 | 24 ± 26 | 2.2 ± 2.3 | 5.4 ± 1.2 |
| Moderate improvement (n = 19) |
62 ± 11 | 43 ± 34 | 3 ± 3.3 | 4.8 ± 1.6 |
| Complete resolution (n = 70) |
62 ± 14 | 46 ± 62 | 2 ± 1.9 | 5 ± 1.6 |
| p | > 0.05 | > 0.05 | > 0.05 | > 0.05 |
a: age values are expressed in years; b: last episode duration is expressed in days.; c: vertigo intensity values are expressed out of 10 at the visual-analogue-scale.
