양성 돌발성 두위 현훈 환자에서 DHI(Dizziness Handicap Inventory)를 통한 주관적 어지럼의 이해

Background and Objectives: The purposes of this study is to understand the self-perceived handicapping effect and the changes of dizziness after canalith repositioning (CRP) maneuver with mastoid percussion in the patients with benign paroxismal positional vertigo (BPPV) using dizziness handicap inventory (DHI). Materials and Method: A total of 83 patients with BPPV visiting the dizziness clinic of Kangnam St. Mary’s Hospital from August, 2002 to July, 2003, were included in this study. DHI questionnaires, checked before and one week after CRP maneuver, were analyzed according to the type of BPPV. Result: The DHI scales of patients with posterior semicircular canal BPPV was 35.2 ± 26.6, 37.5 ± 31.3 with lateral semicircular canal BPPV and 70.0 ± 36.8 with anterior canal BPPV. Especially, Most of the patients had higher scores in physical subscale than other subscales in DHI. Comparing the DHI scale change of before and after CRP maneuver, it made significant decrease in DHI scale after CRP maneuver from 37.1 ±27.0 to 16.3 ± 17.0. Also all subscales of DHI, in other words, physical, functional, emotional factors, were decreased after CRP maneuver (p<0.01). Conclusion: In the patients with BPPV, self-perceived handicapping effects were mainly physical factors. DHI might be usefully applied to the patients with BPPV to understand their dizziness.
