Abstract

BACKGROUND/OBJECTIVES: Vestibulo-ocular reflex (VOR) function, measured by the video head impulse test (vHIT) gains, plays a crucial role in postural stability and quality of life. Cochlear implant recipients often experience vestibular dysfunction, but its relationship with balance and patient-reported outcomes remains underexplored. This study aimed to (1) evaluate the relationship between vHIT gains and postural stability in cochlear implant recipients; (2) assess the impact of vHIT gains on quality-of-life metrics; and (3) identify key predictors of postural stability, including vHIT gains and demographic/clinical characteristics.

METHODS

This cross-sectional study was conducted between August 2023 and February 2024 and included 46 participants that comprised cochlear implant recipients and age-matched normal hearers who underwent the vHIT for lateral, anterior, and posterior semicircular canal function. Postural stability was assessed using dynamic posturography, and quality of life was measured using the Short Form-36 (SF-36). Multiple linear regression and correlation analyses were performed.

RESULTS

The vHIT gains demonstrated significant positive correlations with postural stability, with the lateral canal showing the strongest association (r = 0.742, = 0.001), followed by the posterior (r = 0.701, = 0.003) and anterior canals (r = 0.684, = 0.005). A multiple regression analysis identified the lateral canal as the most significant predictor of postural stability (β = 0.512, = 0.001, adjusted R = 0.47). Quality-of-life metrics were inversely correlated with the vHIT gains, particularly in the posterior canal (r = -0.712, = 0.002), which explained 43-51% of the variance.

CONCLUSIONS

This study highlighted the lateral semicircular canal as the primary determinant of postural stability in cochlear implant recipients, underscoring the importance of vestibular assessments in optimizing balance and functional outcomes.

摘要

背景/目的：通过视频头脉冲试验（vHIT）增益测量的前庭眼反射（VOR）功能在姿势稳定性和生活质量中起着关键作用。人工耳蜗植入者常经历前庭功能障碍，但其与平衡及患者报告结局的关系仍未得到充分研究。本研究旨在：（1）评估人工耳蜗植入者中vHIT增益与姿势稳定性之间的关系；（2）评估vHIT增益对生活质量指标的影响；（3）确定姿势稳定性的关键预测因素，包括vHIT增益及人口统计学/临床特征。

方法

本横断面研究于2023年8月至2024年2月进行，纳入46名参与者，包括人工耳蜗植入者和年龄匹配的正常听力者，他们接受了用于评估水平、前和后半规管功能的vHIT。使用动态姿势描记法评估姿势稳定性，使用简短健康调查问卷（SF-36）测量生活质量。进行了多元线性回归和相关性分析。

结果

vHIT增益与姿势稳定性呈显著正相关，其中水平半规管的相关性最强（r = 0.742，P = 0.001），其次是后半规管（r = 0.701，P = 0.003）和前半规管（r = 0.684，P = 0.005）。多元回归分析确定水平半规管是姿势稳定性的最显著预测因素（β = 0.512，P = 0.001，调整后R² = 0.47）。生活质量指标与vHIT增益呈负相关，尤其是在后半规管（r = -0.712，P = 0.002），这解释了43%-51%的方差。
