通过计算机化姿势描记术评估有和无晕动病个体的姿势稳定性：感觉整合与平衡机制。

文献信息

中文摘要

目的： 通过计算机化动态姿势描记术评估晕动病患者与对照组相比是否存在姿势控制和感觉整合方面的差异。
方法： 开展了一项前瞻性研究，纳入30例晕动病患者和61例无平衡障碍的对照者。所有参与者均使用Horus®平台进行稳定性极限测试和六种姿势描记条件测试。计算平衡分数和感觉比率（躯体感觉、视觉、前庭和视觉偏好）。统计分析采用Mann-Whitney检验、卡方检验和ANCOVA检验，显著性水平为5%。
结果： 经年龄调整后，稳定性极限面积（p = 0.271）或任何姿势描记条件下的平衡分数均未观察到显著差异。两组之间的感觉比率和复合平衡指数也相似。
结论： 晕动病患者的姿势描记表现与对照组相当，提示在无症状发作期间维持平衡的感觉整合功能保留。

英文摘要

OBJECTIVE: To evaluate whether individuals with motion sickness present differences in postural control and sensory integration compared with controls, through assessment with computerized dynamic posturography.
METHODS: A prospective study was conducted including 30 patients with motion sickness and 61 controls without balance disorders. All participants underwent limit of stability testing and the six conditions of posturography using the Horus® platform. Equilibrium scores and sensory ratios (somatosensory, visual, vestibular, and visual preference) were calculated. Statistical analyses were performed using MannWhitney, chisquare, and ANCOVA tests, adopting a 5% significance level.
RESULTS: After age adjustment, no significant differences were observed in the limit of stability area (p = 0.271) or in equilibrium scores under any of the posturography conditions. Sensory ratios and the composite equilibrium index were also similar between groups.
CONCLUSION: Individuals with motion sickness exhibited posturographic performance comparable to controls, suggesting preserved sensory integration for balance maintenance outside symptomatic episodes.
