[Application of the dizziness handicap inventory in the patients with benign paroxysmal positional vertigo]

Abstract

Objective:This study was designed to observe the dizziness handicap inventory (DHI) scores in patients with BPPV (benign paroxysmal positional vertigo) before and after maneuver repositioning and aimed to discuss the values of DHI scores in the diagnosing and treatment of BPPV. Method:Charts of 72 patients with BPPV diagnosed by positioning test were reviewed. Four DHI scores were used including the total score (DHIT), the functional score (DHIF), the emotional score (DHIE), and the physical score (DHIP). We compared the pre-repositioning DHI scores and post-repositioning scores of patients, and also compared the DHI scores of patients with and without residual dizziness. Result:All of the 72 patients were underwent maneuver repositioning and recorded the DHI scores. The mean post-repositioning scores were dramatically decreased compared with pre-repositioning scores, and the difference was significant (P<0.01). The differences of the DHIP scores between the residual dizziness group and the non-residual dizziness group was not significant, while the DHIF scores, the DHIE scores and the DHIT scores between the two groups were statistically different. Conclusion:After maneuver repositioning the dizziness handicap of BPPV patients could be significantly improved. The next treatment program for residual dizziness patients after successful repositioning could be aimed at the functional and emotional dizziness.
