Background and Objectives: Diagnosis of patients with dizziness requires detailed history taking. Using a questionnaire may be helpful for accurate and rapid diagnosis. However, no reliable questionnaire was developed yet. The purpose of this study is to know if authors¡¯ questionnaire is reliable for diagnosing of benign paroxysmal positional vertigo (BPPV) and deciding affected canal.
Materials and Methods: We evaluated 45 patients presenting with positional vertigo from January 2012 to September 2012. We developed a questionnaire by extracting specific questions on positional vertigo from the Dizziness Handicap Inventory and the activities-specific balance confidence scale. All the patients answered the questionnaire, followed by Dix-Hallpike test and head rolling test. Affected canal suspected by the questionnaire was analyzed and compared with affected canal confirmed by positioning test.
Results: Among 45 patients, 24 (53%) was diagnosed with BPPV by positioning test. Patients with posterior canal BPPV (p-BPPV) answered positive of dizziness in pitch axis movement more frequently than roll and yaw, but it was not statistically significant (p>0.05). In the patients with lateral canal BPPV (l-BPPV), no significant difference was observed among three axes. Concordance rate of suspected canal by the questionnaire and positioning test was 36% in p-BPPV and 39% in l-BPPV.
Conclusion: Diagnosis of BPPV and affected canal by the questionnaire based on movement axis is limited in this study. Development of more reliable questionnaire is necessary.
