Proprioception Stimulation in Reducing Residual Dizziness in Patients with Benign Paroxysmal Positional Vertigo after Canalith Repositioning Procedures
Objective This study is aimed to report effecacy of proprioception stimulation in reducing residual dizziness after successful canalith repositioning procedures.Methods Patients with benign paroxysmal positional ver-tigo(BPPV)(n=15,mean age=47.8±14.55 years)were randomly allocated to receive atlanto-occipital mobilization for cervical proprioception stimulation(the study group)or no intervention(the control group)after successful canalith repositioning procedures.The Dizziness Handicap Inventory(DHI)and Visual Analog Scale(VAS)were completed at the first and second visit respectively.Results Post-intervention VAS and DHI scores(including the physical,emotion-al and functional sub-scales)decreased in both groups in comparison to before intervention(P＜0.05),The pre-vs post-intervention difference was greater in the study group than in the control group for VAS scores(P＜0.05)but not for to-tal DHI scores or its physical,emotional and functional subscales(P＞0.05).The pre-vs post-intervention difference in VAS scores,total DHI scores and its functional subscale was greater in the study group than in the control group for patients whose disease course was less than 7 days(P＜0.05)but not for those whose disease course was more than 7 days(P＞0.05).The difference was greater in the study group than in the control group for patients younger than 65 years(P＜0.05),but not for those older than 65 years(P＞0.05).Conclusion Atlanto-occipital mobilization can be uti-l ized as a method in vestibular rehabilitation to reduce subjective residual dizziness in patients with BPPV.
