Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Type of affected semicircular canal (anterior, posterior, or horizontal) and variant (apogeotropic versus geotropic, and canalolithiasis versus cupulolithiasis).Comparison of questionnaire outcomes before and after treatment (ABC-16, DHI, EQ-5D, NPQ, NHV, and HADS).Comparison of the VAS scores as a measure of discomfort during the positional test between the two groups (experimental group versus control group).Recurrence of BPPD during follow-up (1 year).Comparison of the number of fall incidents before and after treatment at 1-year follow-up. | — |
Primary
| Measure | Time frame |
|---|---|
| Number of treatments (using particle repositioning maneuvers) required to completely resolve BPPV (experimental treatment group versus standard treatment group). This is defined as a negative positional test (i.e., no detectable nystagmus on VNG) and no increase in subjective dizziness symptoms during the test.Percentage of patients with a successfully completed treatment versus those with an unsuccessful treatment outcome for BPPV. | — |
