Efficacy of a new home treatment device for benign paroxysmal positional vertigo.

OBJECTIVE To prospectively test the efficacy of a device for the home treatment of benign paroxysmal positional vertigo (BPPV). DESIGN Multicenter prospective cohort study. SETTING Community and tertiary care clinic offices and patient homes. PATIENTS Forty patients with active BPPV. INTERVENTIONS Training on and treatment with a home treatment device (The DizzyFIX) as their primary therapy technique. MAIN OUTCOME MEASURE The Dix-Hallpike maneuver at 1 week after treatment. RESULTS Patients using the home treatment device had no evidence of nystagmus in posttreatment Dix-Hallpike maneuvers at 1 week in 88% of cases (n = 40). This rate was comparable to standard treatment. There were no significant complications. CONCLUSION The use of this device enables patients with an established diagnosis of posterior canal BPPV to safely conduct an effective particle repositioning maneuver and achieve success rates similar to those found with the standard Epley maneuver.
