title: Danhong enhances recovery from residual dizziness after successful repositioning treatment in patients with benign paroxysmal positional vertigo.
abstract: OBJECTIVE
  Although the repositioning maneuvers are usually very effective in patients with BPPV, some patients still complain residual dizziness. Danhong injection (DHI), a traditional Chinese medicine, can effectively dilate blood vessels and improve microcirculation, and has been proven to be effective in improving cervical vertigo and posterior circulation ischemic vertigo. The aim of this study was to evaluate the effects of DHI on residual dizziness after successful repositioning treatment in patients with BPPV.
  
  
  METHODS
  Eighty-six patients with BPPV were randomized into two treatment groups, DHI group and non DHI group. The DHI group received the same repositioning treatment as the non-DHI group, with the addition of DHI therapy. The durations of residual dizziness of DHI group and non-DHI group were compared. In addition, the scores of the dizziness handicap inventory of these two groups were calculated.
  
  
  RESULTS
  The durations of residual dizziness of DHI group were shorter than that of non-DHI group. There were no significant differences in the scores of dizziness handicap inventory in the first week between these two groups, and there were much significant differences in the second, the fourth, the sixth and eighth weeks.
  
  
  CONCLUSIONS
  The results demonstrate that DHI can significantly improve the residual dizziness after successful repositioning treatment in patients with BPPV.
