Objective:
Benign Paroxysmal Positional Vertigo is a vestibular disorder causing vertigo and imbalance. This systematic review and meta-analysis aims to explore the impact of benign paroxysmal positioning vertigo and repositioning maneuvers on postural control.
Data Sources:
In September 2024, PubMed, Web of Science, Scopus and reference lists of included studies were systematically searched. Articles comparing measures of postural control between patients and controls, and/or pre- and posttreatment were considered relevant.
Methods:
Study selection, data extraction and identification of risk of bias were done by two researchers. If possible, meta-analysis was performed with Review Manager version 5.4.1 and standardized mean differences were calculated with a random-effects model.
Results:
Twenty-one of the 37 included studies were useful for meta-analyses. Meta-analyses revealed that benign paroxysmal positional vertigo negatively affects perception of verticality (p < .001; SMD = 0.73; 95% CI = [0.39;1.08]) and sensory orientation (p < .001; SMD = -1.66; 95% CI = [-2.08, -1.23]). The perception of verticality (p < .001; SMD = 0.99; 95% CI = [0.76;1.21]) and sensory orientation (p < .001; SMD = -0.77; 95% CI = [-1.11, -0.44]) improved after treatment with repositioning maneuvers. Results of systematic review indicate stability in gait was impaired, vertigo but improve after repositioning maneuvers. Limits of stability were impaired in older patients, but did not improved after repositioning maneuvers.
Conclusion:
Benign paroxysmal positioning vertigo affects several underlying components of postural control. Repositioning maneuvers can significantly improve the related postural control impairments. This may partly explain the increased odds of falling in these patients, and the positive treatment effect of repositioning maneuvers on falls and fear of falling.
