Abstract:Objective To investigate the recurrence factors and analyze the standing balance function in benign paroxysmal positional vertigo (BPPV) patients after repositioning maneuver.Methods A total of 209 BPPV patients (BPPV group) admitted to our department from Feb 2019 to Dec 2020 were included. All patients received regular telephone follow-up after repositioning maneuvers, and were divided into recurrence group (n=48) and non-recurrence group (n=161) according to follow-up results. Sixty healthy subjects were selected as control. By collecting clinical data, the risk factors for recurrence of BPPV were analyzed by multivariate logistic regression. The sensory organization test (SOT) and the modified clinical test of sensory interaction and balance (mCTSIB) were used to evaluate their static standing balance function. The dynamic and static standing balance function was compared among BPPV patients with different semicircular canal involvement and between the BPPV group and the control group.Results The proportions of age ≥50 years old, female, hypertension, hyperlipidemia, diabetes, vertigo duration ≥1 week and reduction times ≥3 in the recurrence group were higher than those in the non-recurrence group (P<0.05). Multivariate logistic regression analysis showed that age ≥50 years old, female, diabetes, hypertension and hyperlipidemia were risk factors for recurrence after repositioning maneuver of BPPV (P<0.05). The SOT balance scores at open eyes-force plate stability-visual scene follow-up (CON3), open eyes-force plate follow-up-visual scene stability (CON4), closed eyes-force plate follow-up-visual scene stability (CON5), open eyes-force plate follow-up-visual scene follow-up (CON6) of BPPV group with posterior canal involvement were lower than those of the control group (P<0.05), and the average velocities of center of gravity shaking when standing on sponge pad with eyes open and closed were higher than those of the control group (P<0.05).Conclusion Age ≥50 years old, female, hypertension, hyperlipidemia and diabetes are risk factors for recurrence of BPPV after maneuver reduction. BPPV patients with posterior semicircular canal may be prone to stand balance dysfunction.
