ABSTRACT

Objective: To explore the effect of vestibular rehabilitation and to identify factors that can affect rehabilitation outcomes. Methods: From December 2018 to October 2020, patients who underwent vestibular rehabilitation in the Eye, Ear, Nose and Throat Hospital of Fudan University were prospectively followed up. A battery of vestibular function examinations and psychological status evaluations were applied before and after rehabilitation initiation. The main outcomes were vertigo/dizziness and unsteadiness, measured by visual analogue scale (VAS); Secondary outcomes were daily activities and participation, assessed by vestibular activities and participation measure (VAP). Paired t-test was used to compare the effects before and after rehabilitation. Binary logistic regressions were applied to anal yze the influencing factors of rehabilitation outcomes. Results: A total sample of 171 patients was followed up regularly with a median time of 11 months. Of the 171 patients evaluated, 72 were males and 99 were females; age ranged from 10 to 89 years old with a median age of 55 years old. At 6-month follow-up, the difference of VAS score of vertigo/dizziness and unsteadiness pre-post rehabilitation was 1.79±1.80 and 1.56±1.76, respectively; The difference of activity and participation domain of VAP score was 2.51±13 and 1.27±3.75, respectively. All differences pre-post rehabilitation exhibited statistically significant with P values<0.01. Regression analysis demonstrated that the length of symptom onset was a significant predictor of poor balance recovery (OR=6.52; 95%CI:2.10, 20.27). Visual dependence (OR=5.44; 95%CI: 1.38, 21.47) and suspectable anxiety (OR=6.45; 95%CI: 1.49, 28.30) were identified as risk factors for poor recovery of vertigo/dizziness. Conclusions: Vestibular rehabilitation effectively reduces dizziness, promotes balance, and improves the function of daily activities. Time from the onset, visual dependence and suspectable anxiety are the main factors hindering a desirable rehabilitation outcome.
