Dizziness is among the most common reasons that people consult a physician. The two most common causes of dizziness related to peripheral vestibular dysfunction are benign paroxysmal positional vertigo (BPPV) and vestibular hypofunction (VH). Physical therapy (PT) is an effective component of the medical management for both conditions. The occurrence rate of concurrent BPPV and VH in the same patient has not been described in the literature. Identifying patients with co-diagnosis of BPPV and VH will allow the PT to construct a proper treatment sequence. We conducted a retrospective chart review of 500 consecutive medical records of Veteran's Administration male patients with dizziness referred for videonystagmography (VNG). Co-diagnosis of BPPV and VH, ipsilateral versus contralateral presentation, frequency of referral to PT, and age were recorded. Single diagnosis (38%) was more common than co-diagnosis (6.6%), and ipsilateral presentation of co-diagnosis (48.5%) more frequent than contralateral presentation (33.3%). Additionally, 80.7% of patients who tested positive for a peripheral vestibular disorder were not referred to PT. Age may be related to the occurrence of co-diagnosis of BPPV and VH.
