Clinical research of repositioning maneuver therapy for benign paroxysmal positional vertigo

[Objective]To assess the efficacy of repositioning maneuver therapy on benign paroxysmal positional vertigo (BPPV).Methods Patients with unilateral BPPV were randomly divided into two groups,repositioning group and control group.Patients in repositioning group received repositioning maneuver therapy and patients in control group only received postural restriction therapy.Results There were 63 patients in repositioning group and 60 patients in control group.The success rates in repositioning group and control group were 82.5％(52/63)and 18.3％(11/60)respectively on the fourth day,there was a significant difference between the two groups (x2=50.706,P＜0.01),and on the seventh day,the rates were 92.1％(58/63)or 31.6％(19/60),the difference was also significant (x2=47.882,P＜0.01).Conclusions The efficacy of repositioning maneuver therapy was superior to that of the control group.If no contraindications,all patients should be treated with repositioning maneuver therapy when the diagnosis of BPPV is definite.
