姿势控制障碍是脑震荡后的主要症状。计划性步态终止（GT）是一项非新颖的动态任务，它挑战了神经功能缺陷患者的姿势控制，它可能是识别脑震荡后动态姿势控制障碍的一种有影响力的措施。因此，本研究的目的是评估急性脑震荡后动态姿势控制利用计划GT任务。脑震荡参与者（n= 19，年龄：19.0 ± 0.8岁，身高：177.0 ± 10.1 cm，体重：83.3 ± 20.0 kg）在季前基线测试（基线）和脑震荡后第1天（第-1天）完成了5项计划的GT试验。健康对照受试者（n=19，年龄：20.4 ± 1.2岁，身高：173.8 ± 8.9 cm，体重：80.2 ± 17.6 kg）间隔一周完成相同的试验。感兴趣的因变量包括在计划GT的三个阶段（制动、过渡、稳定）中，内外侧（ML）和前后（AP）轴的COP位移和速度。在制动ML和过渡AP位移（p= 0.042，p= 0.030）和速度（p= 0.027，p= 0.030）中观察到显著的相互作用。这些结果表明，保守的脑震荡后电机控制策略在计划GT。此外，这些结果支持使用动态姿势控制任务作为脑震荡后损伤的措施。
Impaired postural control is a cardinal symptom following concussion. Planned gait termination (GT) is a non-novel, dynamic task that challenges postural control in individuals with neurological deficits, and it could be an impactful measure for identifying dynamic postural control impairments following concussion. Therefore, the purpose of this study was to assess acute post-concussion dynamic postural control utilizing a planned GT task. The concussion participants (n= 19, age: 19.0 ± 0.8 years, height: 177.0 ± 10.1 cm, weight: 83.3 ± 20.0 kg) completed five planned GT trials during preseason baseline testing (Baseline) and on Day 1 post-concussion (Day-1). Healthy control participants (n=19, age: 20.4 ± 1.2 years, height: 173.8 ± 8.9 cm, weight: 80.2 ± 17.6 kg) completed the same trials a week apart. The dependent variables of interest included COP displacement and velocity in the mediolateral (ML) and anteroposterior (AP) axes during the three phases (braking, transitional, stabilization) of planned GT. There were significant interactions observed in both the braking ML and transitional AP displacement (p= 0.042, p= 0.030) and velocity (p= 0.027, p= 0.030). These results suggest a conservative post-concussion motor control strategy during planned GT. Further, these results support the use of dynamic postural control tasks as measures of post-concussion impairments.
