ABSTRACT
Objective:
To compare the effects of different intervention strategies for the management of residual dizziness following successful canalith repositioning procedure (CRP) in patients with benign paroxysmal positional vertigo (BPPV).Methods:
A total of 129 BPPV patients with residual dizziness following successful CRP were recruited during January 2019 and July 2019. They were randomly assigned into three groups with 43 cases in each group the vestibular rehabilitation group received rehabilitation training for four weeks; betahistine group was given orally 12 mg betahistine three times a day for four weeks; and the control group had no specific treatment. The primary outcomes were daily activities and social participation assessed by the Vestibular Activities and Participation measure (VAP). Secondary outcomes includedbalance function assessed by sensory organization test (SOT) and the duration of residual symptoms. Stata15.0 software was used for statistical analysis.Results:
The scores of VAP in the three groups decreased over time, but a more significant decrease was found in vestibular rehabilitation group. Further paired comparison showed that the difference between the vestibular rehabilitation group and the control group was of statistical significance (B=-3.88, χ2=18.29, P<0.01), while the difference between the betahistine group and the control group was not statistically significant (B=-0.96, χ2=1.16, P=0.28). The balance function of the three groups showed a trend of recovery over time, with no significant differences between groups (χ2=1.37, df=2, P>0.05). The median duration of residual dizziness for both vestibular rehabilitation and betahistine groups was 14 days, while that of control group was 19 days, with no significant difference between three groups[Log-rank (Mantel-Cox) test; χ2=1.82, df=2, P=0.40].Conclusion:
Vestibular rehabilitation can significantly improve the daily activities and social participation function in BPPV patients with residual symptoms following successful CRP, but its effects on shortening the duration of residual symptoms and promoting the recovery of balance function remain uncertain.
