Benign paroxysmal positional vertigo (BPPV) is one of the critical life events that can affect physical, emotional, and functional aspects of quality of life. Canalith repositioning procedure (CRP) provides rapid and long lasting relief of symptoms in most patients with BPPV. However, some patients express nonspecific symptoms such as anxiety or discomfort after treatment, The purpose of this study was to assess the residual symptoms after CRP in patients with BPPV using Dizziness Handicap Inventory (DHI) in a questionnaire format and to evaluate the therapeutic efficacy of CRP according to accompanying the DizzyFIX device.
We performed a prospective investigation in 135 consecutive patients with confirmed posterior semicircular canal BPPV. CRP was performed until nystagmus and vertigo disappeared. Patients were divided into three group using the DizzyFIX (group A), not using the DizzyFIX (group B) and closed observation (group C) after treatment. Then patients were asked to complete the questionnaire for Korean form DHI before treatment, 1, 2, 3, 4, and 8 week after treatment.
There was a significant improvement in DHI scores when comparing the pre CRP and post CRP three groups (p<0.05), although emotional items showed incomplete improvement at 1 week. But at 2 week after treatment, there were statistically significant differences between group A and other groups in DHI scores specially in emotional items.
Even after successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms may remain. For these patients additional follow up and management are necessary and using of the DizzyFIX will be helpful to reduce the incidence of residual dizziness especially emotional aspect.
