本研究的目的是评估姿势摇摆变异性作为一种潜在的评估工具，以检测与脑震荡有关的症状的青年改变姿势摇摆。40名参与者（20人健康，20人受伤）年龄在10至16岁进行了评估，使用平衡误差评分系统（BESS）和姿势摇摆变异性分析应用于中心的压力数据使用测力板。观察到两组之间的姿势摇摆变异性指标存在显著差异，但BESS无显著差异。具体来说，与健康的参与者相比，受伤的参与者的路径长度更短，样本熵和Renyi熵更有规律（P <0.05）。这项研究的结果表明，姿势摇摆变异性可能是一个更有效的措施比BESS检测脑震荡后的变化，在姿势控制的年轻运动员。
The purpose of this study was to evaluate the utility of postural sway variability as a potential assessment to detect altered postural sway in youth with symptoms related to a concussion. Forty participants (20 who were healthy and 20 who were injured) aged 10 to 16 years were assessed using the Balance Error Scoring System (BESS) and postural sway variability analyses applied to center-of-pressure data captured using a force plate. Significant differences were observed between the 2 groups for postural sway variability metrics but not for the BESS. Specifically, path length was shorter and Sample and Renyi Entropies were more regular for the participants who were injured compared with the participants who were healthy (P < .05). The results of this study indicate that postural sway variability may be a more valid measure than the BESS to detect postconcussion alterations in postural control in young athletes.
