RESUMO
OBJECTIVE: Benign Paroxysmal Positional Vertigo (BPPV) as the most common vestibular disorder can affect the quality of life. This study aimed to compare the effectiveness of the half somersault maneuver (HSM) as a treatment to that of the Epley maneuver (EM) as a clinical-based treatment in subjects with PC-BPPV. METHODS: In this randomized study, 43 participants with unilateral posterior canal BPPV were recruited. The experimental group received the HSM, whereas the control group received the EM. All participants were asked to fill in the Vestibular Rehabilitation Benefit Questionnaire (VRBQ), Dizziness Handicap Inventory (DHI), and Vertigo Symptom Scale (VSS) questionnaires at pretreatment and at 48 hours, 1 week, and 1 month posttreatment. The severity of residual dizziness was determined by the visual analog scale (VAS) weekly for up to 4 weeks after treatment. The success rate and the recurrence rate were assessed after the 3-month follow-up. RESULTS: The differences between the results of pretreatment and post-treatment questionnaires for both groups were significant. However, the differences were not significant between the 2 groups for the DHI scores, the total, dizziness, motion-provoked dizziness, and symptom subscale scores of the VRBQ, and the anxiety subscale scores of the VSS. There were significant differences between the 2 groups for VAS, the total VSS and vertigo subscale scores, and the VRBQ anxiety subscale scores. CONCLUSION: Even though both maneuvers are significantly effective in the treatment of PC-BPPV, subjects in the HSM group reported more improvement in terms of psychometric symptoms and residual dizziness compared to the EM group.
