The effect of self-management vestibular rehabilitation on persistent postural-perceptual dizziness

To investigate the effects of self-management vestibular rehabilitation (VR) on the subjective symptoms of dizziness and postural stability in persistent postural-perceptual dizziness (PPPD).

Retrospective case review.

The medical records of 30 patients newly diagnosed with PPPD based on the Bárány Society's diagnostic criteria were reviewed. Nineteen patients (4 males and 15 females; age range 27-84 years, mean age ± standard deviation 57.4 ± 14.2 years) who was newly instructed to self-management VR were included and instructed to perform self-management VR for 2 months.

One patient did not visit the outpatient clinic again, and in the remaining 18 patients, 4 (22%) discontinued VR at their own discretion. In the 12 patients who completed 2 months of VR (67%), there was a significant improvement in Niigata PPPD Questionnaire (NPQ) and Dizziness Handicap Inventory (DHI) scores after VR compared to those before VR (p < .05). However, the mean velocity of center of pressure (COP) movement (velocity) and the envelopment area traced by COP movement (area), as well as the Romberg ratio and foam ratio of velocity and area, did not differ significantly after VR when compared to those before VR (p > .05).

For PPPD, self-management VR improved subjective symptoms of dizziness, but not stability of standing posture. It is necessary to improve patients' adherence to the treatment.
