Balance assessment is an integral component of concussion evaluation and management. Although the modified balance error scoring system (mBESS) is the conventional clinical tool, objective metrics derived from wearable inertial sensors during the mBESS may increase sensitivity in detecting subtle balance deficits post-concussion. The aim of this study was to identify which stance condition and postural sway metrics obtained from an inertial sensor placed on the lumbar spine during the mBESS best discriminate athletes with acute concussion. Fifty-two college athletes in the acute phase of concussion and seventy-six controls participated in this study. Inertial sensor-based measures objectively detected group differences in the acutely concussed group of athletes while the clinical mBESS did not (p < 0.001 and p = 0.06, respectively). Mediolateral postural sway during the simplest condition of the mBESS (double stance) best classified those with acute concussion. Inertial sensors provided a sensitive and objective measure of balance in acute concussion. These results may be developed into practical guidelines to improve and simplify postural sway analysis post-concussion.
平衡评估是脑震荡评估和管理的一个组成部分。虽然改良平衡错误评分系统（mBESS）是常规的临床工具，但在 mBESS 期间从可穿戴惯性传感器获得的客观指标可能会提高检测脑震荡后细微平衡缺陷的敏感性。本研究的目的是确定在 mBESS 期间放置在腰椎上的惯性传感器获得的哪种站位条件和姿势摆动指标最能区分急性脑震荡的运动员。52 名处于脑震荡急性期的大学生运动员和 76 名对照组参加了这项研究。惯性传感器基于指标客观地检测到了急性脑震荡运动员组的群体差异，而临床 mBESS 则没有（分别为 p<0.001 和 p=0.06）。在 mBESS 最简单的条件（双足站位）下的横向姿势摆动最能区分急性脑震荡者。惯性传感器为急性脑震荡提供了一种敏感和客观的平衡测量方法。这些结果可能会发展成为改善和简化脑震荡后姿势摆动分析的实用指南。
