[A pre- and post-treatment study of quality of life in patients with benign paroxysmal positional vertigo].

OBJECTIVE: To explore the effect of canalith repositioning procedure (CRP) on the quality of life (QOL) in patients with benign paroxysmal positional vertigo(BPPV).

METHOD: The clinical data of 86 patients with BPPV (treatment group) and 120 normal ones (control group) were reviewed through the medical outcomes study short form (SF-36)and the dizziness handicap inventory (DHI), and the results of two groups were analyzed.

RESULT: With SF-36 scales for evaluation of QOL, the results showed that the scores of treatment group before CRP were significantly lower than that of the control group (P < 0.05). While using of DHI scales in evaluation of the treatment group patients before CRP, the results were significantly higher than that of the control group (P < 0.05). After CRP for 3 months, not only with SF-36 scales but also with DHI scales, there were no significant difference between the two groups (P > 0.05).

CONCLUSION: CRP may obviously improve the clinical symptom of BPPV patients. The SF-36 and DHI scales could reflect the change of BPPV patient's QOL.
