Objective To explore the influencing factors of residual symptoms after successful repositioning maneuvers in benign paroxysmal positional vertigo（ BPPV）. Methods The paper was a prospective study including 42 patients diagnosed with BPPV who were admitted to the dizziness outpatient department of Shanghai Changzheng Hospital. A variety of data were collected， including the general medical history of both onset and one week after successful repositioning maneuvers and the results of Dizziness Handicap Inventory （DHI）， Hospital Anxiety Depression Scale（ HADS） and ocular vestibular evoked myogenic potentials（ o-VEMP）. Patients were categorized into two groups according to the presence or absence of residual symptoms after successful repositioning maneuvers. Logistic regression analysis was used to determine the factors affecting the residual symptoms. Results A total of 41 patients completed the follow-up investigation， 12（29.3%） of which presented residual dizziness one week after successful repositioning maneuvers. The average age and duration of vertigo of the residual symptoms group were all higher than those of the non-residual symptoms group（ P＜0.05）. A significantly higher amplitude of o-VEMP was observed in patients with residual dizziness after successful repositioning maneuvers than those without（ P＜ 0.05）. Patients with residual dizziness presented a higher DHI-E（ Emotion） score and a higher HADS score than the patients in the non-residual symptoms group（ P＜0.01）. The Logistic regression analysis revealed that the emotional state during onset was an independent risk factor for residual dizziness after successful repositioning maneuvers（ P ＜ 0.05）. Conclusions The residual dizziness in BPPV is affected by various factors， with anxiety and depression being the major factors. Intervention of psychological state for BPPV patients during onset might prevent or alleviate the occurrence of residual dizziness.
