Retrospective review and telephone follow-up to evaluate a physical therapy protocol for treating persistent postural-perceptual dizziness: A pilot study.

Background: Persistent postural-perceptual dizziness (PPPD) (formerly chronic subjective dizziness) may be treated using the habituation form of vestibular and balance rehabilitation therapy (VBRT), but therapeutic outcomes have not been formally investigated.

Objective: This pilot study gathered the first data on the efficacy of VBRT for individuals with well-characterized PPPD alone or PPPD plus neurotologic comorbidities (vestibular migraine or compensated vestibular deficits).

Methods: Twenty-six participants were surveyed by telephone an average of 27.
