Supplementary Material - Objectives
This study was performed to investigate whether vestibular dysfunction affects health-related quality of life in Korean adults.
Methods
This retrospective cross-sectional study was performed with data from the 2010 to 2011 Korea National Health and Nutrition Survey for adults aged 40 years or more. The modified Romberg test and health-related quality of life evaluation using the EuroQoL 5-dimensional (EQ-5D) questionnaires were performed. Data were analyzed using a complex-sample chi-square test of independence and multivariate linear regression analysis. The main outcome measures were vestibular dysfunction and the calculated health-related quality of life questionnaire score.
Results
The overall prevalence of vestibular dysfunction was 3.4% (95% confidence interval, 2.5%–4.3%). In adults aged more than 40 years, multivariate linear regression analyses showed a significant reverse correlation between vestibular function and health-related quality of life since the EQ-5D index showed a lower score than normal (B coefficient=‒0.09, R2=0.299, p=0.003) for a decrease in balance function, and the scores for mobility, self-care, general activities, and pain/discomfort were worse, except for anxiety/depression. On the other hand, subjective dizziness was significantly associated with the EQ-5D index and all its subcategories.
Conclusions
Since adults with vestibular dysfunction have poor health-related quality of life, active monitoring and rehabilitation are necessary.

- Background and Objectives: Although several methods of repositioning maneuver have been introduced for the benign paroxysmal positional vertigo involving horizontal canal (HC-BPPV), no study has investigated the nystagmus pattern during the repositioning maneuver and its correlation with the repositioning results. Therefore, we evaluated the predictive value of the nystagmus for successful repositioning by studying the nystagmus pattern during the position of the Gufoni’s maneuver. Materials and Methods: Seventeen consecutive patients (age range=36~76 years, median age=64), with a diagnosis of HC-BPPV were recruited between July and August 2010. The Gufoni's maneuver for apogeotropic and geotropic nystagmus was performed. After 30 minutes, the treatment outcome was evaluated according to the nystagmus pattern at the individual stage of Gufoni’s maneuver. Successful treatment was defined by the resolution of positional vertigo in geotropic HC-BPPV and nystagmus shifted from apogeotropic to geotropic in apogeotropic HC-BPPV. Results: In the successfully treated patients, 4 of 6 patients had the contralesional nystagmus between 1st and 2nd position of Gufoni’s maneuver. Ipsilesional nystagmus in 1st position of Gufoni’s maneuver was observed in 1 patient with apogeotropic nystagmus. And the other 1 patient with Geotropic HC-BPPV showed no nystagmus in 2nd position after contralesional nystagmus in 1st position of Gufoni’s maneuver. Unsuccessfully treated 11 patients had a conversion of nystagmus direction in 2nd position after 1st step. Conclusion: During the 2nd position of the Gufoni’s maneuver, a nystagmus toward unaffected side predicts a successful repositioning, whereas reversed nystagmus is suggestive of poor response to repositioning.
