Correlation between Rotating Chair Test and Dizziness Handicap Inventory in Patients with Acute Unilateral Vestibular Neuritis / 대한평형의학회지

ABSTRACT

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.
