OBJECTIVE: The aim of this study was to determine the effectiveness of the
canalith repositioning procedure (CRP) in the treatment of benign paroxysmal
positional vertigo (BPPV) among patients after mild-to-moderate traumatic brain
injury.
METHODS: An unblinded, nonrandomized, case comparison interventional study with
repeated measures (1, 5, 9, and 12 weeks postenrollment) of three groups of
patients with traumatic brain injury (BPPV, n = 21; nonspecific dizziness, n =
23; no dizziness, n = 12) was conducted. Patients in the BPPV group received the
CRP at baseline and repeatedly until a negative Dix-Hallpike Maneuver was
observed. Participants in the other two groups did not receive the CRP.
RESULTS: Symptom resolution at the 12-week follow-up was observed in 75% of
patients in the BPPV group versus 8.3% in the nonspecific dizziness group (p =
.0006). A significant Group × Time interaction was observed for the Dizziness
Handicap Inventory (F = 4.2, p = .003) and 36-item Short Form Health
Questionnaire physical component scores (F = 2.16, p = .035) with the BPPV group
showing significantly improved scores by the 12-week follow-up. Although there
were between-group differences on the 36-item Short Form Health Questionnaire
mental health component scores (F = 4.06, p = .022), changes over time were not
significant in the groups.
CONCLUSIONS: Treatment with the CRP for posttraumatic BPPV resulted in
significant symptom resolution and improvement in perceived physical health
status.
