Correlation between residual dizziness after repositioning of benign paroxysmal positional vertigo and motion...

During the onset of benign paroxysmal positional vertigo (BPPV), patients with motion sickness may experience more severe vestibular symptoms, which may affect the occurrence of residual dizziness (RD).

To study the correlation between RD after BPPV and motion sickness.

According to the history of motion sickness, the clinical characteristics of BPPV combined with motion sickness were analyzed. According to whether there was RD after successful repositioning, the patients were divided into RD group and non-RD group. The differences between the two groups were analyzed first, and then the influencing factors of RD were analyzed.

① The proportion of women, dizziness handicap inventory (DHI) score, Hamilton Anxiety Scale (HAMA) score and incidence of RD in the motion sickness group were higher than those in the non-motion sickness group. ② The age, course of diseases, history of BPPV, history of motion sickness, DHI score and HAMA score in the RD group were higher than those in the non-RD group. ③ History of motion sickness, age, course of disease, history of BPPV, DHI, and HAMA were the influencing factors of RD.

Motion sickness is associated with RD, and may serve as a clinical indicator for risk stratification.
