Abstract：Objective To investigate the factors that lead to the poor immediate effect of reposition for benign paroxysmal positional vertigo.Methods Ninety-five cases of BPPV patients with poor immediate effect after the automatic vestibular function diagnosis and therapy system(SRM-Ⅳ) treatment at our hospital between January 2016 and December 2017 were selected as the ineffective group, while 285 cases with immediate effect served as the effective group. Clinical features were compared between the two groups to identify the causes of poor immediate effect.Results Multivariate analysis of logistic regression showed that head injury, vestibular neuritis and sudden deafness were risk factors for poor immediate effect for benign paroxysmal positional vertigo (OR was 3.444, 10.009 and 5.934, respectively, P<0.05). Poor immediate effect was more likely to occur in the multiple semicircular canal (BPPV) than in the posterior semicircular canal or the horizontal semicircular canal BPPV (P<0.05).Conclusions The effect of basic examination ought to be improved to detect risk factors for poor immediate effect for BPPV earlier, and targeted approaches have to be devised to reduce the times of reposition and shorten the course of treatment.
