Driving simulator studies show that individuals with acute concussion present notable alterations in driving performance and perform better as recovery progresses. Although driving simulators create a safe environment and are capable of immersing individuals in realistic driving scenarios, they fail to capture daily naturalistic driving behavior throughout concussion recovery. Therefore, the purpose of the study was to assess the feasibility of collecting naturalistic driving and explore driving behaviors and risk events in individuals with concussion, relative to the control group. Twelve individuals with concussion and 17 non-concussed controls installed a GPS sensor in their personal vehicle for a 14-day period. We compared driving behavior (total distance driven, total duration driven, average speed, and number of trips taken per day) and risk events (number of hard brakings and sudden accelerations) captured between groups. Hedge's g and linear mixed regression models were used to compare driving behavior and risk events. Individuals with concussion appeared to drive less and slower prior to day 3 post-concussion but displayed similar driving behavior after day 3 of post-concussion, relative to the control group. Additionally, we observed a pattern that the concussion group drove slower than the control group across concussion recovery. Our study provides preliminary evidence that suggests a need for a return to driving strategy to ensure the safety of individuals with concussion.
驾驶模拟器研究表明，患有急性脑震荡的个体在驾驶表现上存在显著变化，且随着恢复进程，驾驶表现会有所改善。尽管驾驶模拟器营造了一个安全的环境，能够让个体沉浸在逼真的驾驶场景中，但它们无法捕捉脑震荡恢复过程中个体日常的自然驾驶行为。因此，本研究的目的是评估收集自然驾驶数据的可行性，并探究脑震荡个体相对于对照组的驾驶行为和风险事件。12名脑震荡个体和17名未患脑震荡的对照组人员在其个人车辆中安装了GPS传感器，为期14天。我们比较了两组之间捕捉到的驾驶行为（总行驶距离、总驾驶时长、平均速度和每日出行次数）和风险事件（急刹车和突然加速的次数）。使用赫奇斯g值和线性混合回归模型来比较驾驶行为和风险事件。相对于对照组，脑震荡个体在脑震荡后第3天之前似乎驾驶得更少、更慢，但在脑震荡后第3天之后表现出类似的驾驶行为。此外，我们观察到一种模式，即在整个脑震荡恢复过程中，脑震荡组的驾驶速度比对照组慢。我们的研究提供了初步证据，表明需要制定恢复驾驶策略以确保脑震荡个体的安全。
