Objective: Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause for peripheral vestibular vertigo. However, some patients still complain Residual Dizziness (RD) even after a successful Canalith Repositioning Procedure (CRP). This study was to explore the features of RD and its association with social support.

Subjects and Methods: Between January 2015 and January 2016, 258 patients with BPPV were prospectively recruited in this study. The presence of RD was investigated after a successful CRP. Social Support Rating Scale (SSRS) and Dizziness Handicap Inventory (DHI) were adopted to evaluate the status of social support and the self-perceived handicapping effects of RD respectively.

Results: Of them, 105 patients complained of RD after successful CRP. Univariate analysis indicated that the age, female sex, the length from BPPV onset to CRP and DHI score and SSRS score were significantly different between patients with RD and those without. After adjusting the confounding factors, multivariate logistic regression analysis suggested that the SSRS total score (OR 0.923, 95% CI 0.889-0.958, P=0.000) and the 3 subdomains of SSRS (subject support (OR 0.912, 95% CI 0.869-0.956, P=0.000), objective support (OR 0.889, 95% CI 0.799-0.989, P=0.031), and degree of social utilization (OR 0.825, 95% CI 0.716-0.951, P=0.008) ) were independently associated with the presence of RD after CRP. In conclusion, Residual dizziness is a common condition in patients with BPPV after CRP.

Conclusion: Our study indicates that social support could help in reducing the incidence of RD in patients with BPPV after successfully CRP and returning to daily life more rapidly and comfortably.
