High-technology methods demonstrate that balance problems may persist up to 30 days after a concussion, whereas with low-technology methods such as the Balance Error Scoring System (BESS), performance becomes normal after only 3 days based on previously published studies in collegiate and high school athletes.
To compare the National Institutes of Health's Balance Accelerometer Measure (BAM) with the BESS regarding the ability to detect differences in postural sway between adolescents with sports concussions and age-matched controls.
Cohort study (diagnosis); Level of evidence, 2.
Forty-three patients with concussions and 27 control participants were tested with the standard BAM protocol, while sway was quantified using the normalized path length (mG/s) of pelvic accelerations in the anterior-posterior direction. The BESS was scored by experts using video recordings.
The BAM was not able to discriminate between healthy and concussed adolescents, whereas the BESS, especially the tandem stance conditions, was good at discriminating between healthy and concussed adolescents. A total BESS score of 21 or more errors optimally identified patients in the acute concussion group versus healthy participants at 60% sensitivity and 82% specificity.
The BAM is not as effective as the BESS in identifying abnormal postural control in adolescents with sports concussions. The BESS, a simple and economical method of assessing postural control, was effective in discriminating between young adults with acute concussions and young healthy people, suggesting that the test has value in the assessment of acute concussions.
高科技方法表明，平衡问题可能在脑震荡后持续长达 30 天，而使用低科技方法，如平衡错误评分系统（BESS），根据之前在大学生和高中生运动员中的研究，仅在 3 天后表现就会恢复正常。
比较美国国立卫生研究院的平衡加速度计测量（BAM）与 BESS 在检测运动性脑震荡青少年与年龄匹配对照组之间姿势摆动差异的能力。
队列研究（诊断）；证据水平，2 级。
43 名脑震荡患者和 27 名对照参与者接受标准 BAM 方案测试，同时使用骨盆加速度在前后方向的归一化路径长度（mG/s）量化摆动。BESS 通过视频记录由专家进行评分。
BAM 无法区分健康和脑震荡青少年，而 BESS，特别是在前后位站立条件下，擅长区分健康和脑震荡青少年。总 BESS 评分为 21 或更多错误，可在 60%的灵敏度和 82%的特异性下最佳识别急性脑震荡组中的患者。
BAM 不如 BESS 有效，无法识别运动性脑震荡青少年的异常姿势控制。BESS 是一种简单且经济的评估姿势控制的方法，可有效区分急性脑震荡的年轻人和健康年轻人，表明该测试在急性脑震荡评估中具有价值。
