Abstract

OBJECTIVE:

To develop and test a completely new dynamic visual device for the home treatment of benign paroxysmal positional vertigo (BPPV).

DESIGN:

Randomized, controlled, prospective trial.

SETTING:

Tertiary care hospital.

METHODS:

We designed and manufactured a new device (the DizzyFix) to assist in the performance of the particle repositioning manoeuvre (PRM). Fifty healthy volunteers were taught the PRM, half using the new device. At 1 week, we compared the PRM performance between the device and nondevice user groups.

MAIN OUTCOME MEASURES:

Performance of the PRM as graded on an 11-point scale.

RESULTS:

DizzyFix users in phase I scored significantly higher on their PRM performance compared with controls (p = .0001).

CONCLUSIONS:

The use of this new device enables volunteers to conduct a correct PRM on their own. This is a significant improvement from written instructions or in-office training.
