【摘要】 目的:建立国内20～69岁健康人群不同年龄组动态平衡功能参数的正常参考范围。方法:选取100名健康受试者，按年龄分为20～29岁、30～39岁、40～49岁、50～59岁、60～69岁5组，每组男女各10例。采用EquiTest动态平衡测试系统进行感觉统合试验(sensory organization tests, SOT)、运动控制试验(motor control tests, MCT)、自适应试验(adaptation test, ADT)和稳定极限试验(limits of stability, LOS)测试，统计分析各参数以■表示。结果:获得了各年龄组SOT、MCT、ADT和LOS参数的正常参考值范围。平衡功能多项参数随年龄增长呈逐渐下降趋势，60岁后衰退尤为显著，具体表现为SOT中前庭觉权重降低、视觉优势偏向减弱，LOS中反应时间延长、方向控制能力下降及向后方向最大移动距离减少。结论:本研究首次建立了国内20～69岁健康人群分年龄段的动态平衡功能参数参考范围，为国人平衡功能的客观评估及相关疾病的临床诊断提供了本土化依据。更多还原

【Abstract】 Objective: To establish normal reference value ranges for dynamic balance function parameters in healthy Chinese adults aged 20-69 years. Methods: A total of 100 healthy subjects were selected and evenly divided into five age groups: 20-29, 30-39, 40-49, 50-59, and 60-69 years, with equal gender distribution in each group. Balance function was assessed using the EquiTest system(NeuroCom), with following tests performed Sensory Organization Test(SOT), Motor Control Test(MCT), Adaptation Test(ADT), and Limits of Stability(LOS) test. All parameters were statistically analyzed and expressed as ■. Results: The normal reference ranges for SOT, MCT, ADT, and LOS parameters were established for each age group. Multiple balance function parameters demonstrated a gradual decline with advancing age, with more pronounced deterioration observed after the age of 60. Specific findings included decreased vestibular ratio and reduced visual preference in SOT, as well as prolonged reaction time, impaired directional control, and reduced maximum excursion in the backward direction during LOS testing.Conclusion: This study is the first to establish age-specific reference ranges for dynamic balance function parameters in a healthy Chinese population aged 20-69 years, providing localized and objective criteria for the assessment of balance function and supporting clinical diagnosis of balance-related disorders in China.更多还原
