| Popis: | BACKGROUND: While patients with benign paroxysmal positional vertigo (BPPV) commonly develop residual dizziness (RD) after successful repositioning, the factors predictive of RD remain controversial. OBJECTIVE: To identify factors predictive of RD onset in patients with BPPV following successful repositioning. METHODS: This multi-center prospective cohort study enrolled 243 patients with idiopathic BPPV. Vestibular functional and psychological wellbeing assessments administered before repositioning provided the data used to identify factors predictive of RD with a log-binomial model. The endpoint was RD at 1 week after successful repositioning. RESULTS: Of the enrolled patients, 118 reported RD. After adjusting for cofounders, mild [risk ratio (RR), 2.06; 95% confidence interval (CI), 1.39–3.04] or severe (RR, 3.08; 95% CI, 2.17–4.38) anxiety and abnormal vestibular ratio of sensory organization test (RR, 2.68; 95% CI, 1.82–3.95) were identified as risk predictors. Presence of ocular vestibular evoked myogenic potentials responses, either unilateral (RR, 0.55; 95% CI, 0.44–0.69) or bilateral (RR, 0.49; 95% CI, 0.36–0.68), were protective factors. CONCLUSIONS: Anxiety and abnormal balance are significant predictors of RD, while the presence of ocular vestibular evoked myogenic potentials responses predicts against it. These findings may help to improve BPPV outcomes by informing prognoses and guiding treatment strategies. Trial registration: ChiCTR1800018004 (date of registration: 26 August 2018) |
