Objectives This study was performed to investigate the correlation between subjective residual dizziness and objective postural imbalance after successful canalith repositioning procedure (CRP) in benign paroxysmal positional vertigo (BPPV) by using questionnaires and modified Clinical Test of Sensory Integration and Balance (mCTSIB).
Methods A total of 31 patients with BPPV were included prospectively in the study. All included patients were successfully treated after initial CRP and their symptoms and nystagmus disappeared. Two weeks after CRP, all patients were asked to fill out the questionnaire including both Dizziness Handicap Inventory (DHI) and visual analog scale (VAS). We also conducted mCTSIB 2 weeks after CRP. We divided patients into two groups according to VAS: RD (residual dizziness) group, VAS>0; non-RD group, VAS=0. We compared age, number of CRP, rates associated with three semicircular canals, DHI score and mCTSIB results between two groups. In addition, we analyzed the correlation between DHI score and mCTSIB results.
Results There were no significant differences in age, number of CRP, and rates associated with three semicircular canals between the two groups. RD group showed significantly higher DHI score and abnormal mCTSIB results than the non-RD group (p<0.05). DHI score and the number of abnormal mCTSIB showed a statistically significant correlation.
Conclusions We demonstrated the correlation between DHI score and mCTSIB after successful CRP for BPPV. It also represents that subjective residual dizziness is correlated with objective postural imbalance even after successful CRP. Therefore, mCTSIB would be a useful test to evaluate both residual dizziness and postural imbalance after CRP in BPPV.

OBJECTIVE: Vestibular neuritis (VN) is one of the most common causes of acute spontaneous vertigo. However, such dizziness symptoms in patients with VN vary among patients, and various methods are used to evaluate subjective vestibular symptoms following attack of VN. Studies on correlation between subjective vestibular symptom changes and result of rotation chair test after vestibular rehabilitation therapy (VRT) have not been reported.
Therefore, we compared change of dizziness handicap inventory (DHI) and results of rotation chair test in patients with VN between attack and 3 month later following VRT.
METHODS Forty-seven patients were included in this study.
In patients with VN, DHI and rotation chair test were performed at the time of VN attack and recovery time of 3 months after VN attack.
RESULTS In general, the DHI score and the percentage of directional preponderance (DP) in a rotation chair test performed on patients with VN have all decreased. However, the changes in these results were not statistically significant. DP% difference and DHI score were compared to each other among patients with VN and showed no relational significance to each other (r=0.326).
CONCLUSION The degree of improvement in a rotation chair test done on patients with VN did not reflect the severity of improvement for symptom like dizziness.
