In this pilot study, we investigated the impact of a sport-related concussion (SRC) on the ability to form cognitive maps, mental representations of the environment that are critical for spatial orientation and navigation.
We recruited 18 adolescent hockey players suffering from a SRC, and 19 age, sex and handedness-matched hockey players with no history of concussion.
We asked participants to perform the Spatial Configuration Task (SCT), a computerized tool used to quantitatively measure the ability of the individuals to form cognitive maps.
We found that athletes with a concussion performed significantly worse than controls on the SCT ((1,34) = 5.82, =.021, [Formula: see text] = -0.72), confirming a negative effect of a SRC on the ability to form cognitive maps. We found no significant difference between groups in average response time, and no significant correlation between participants' performance at the SCT and reported symptoms of concussion as rated on the Sport Concussion Assessment Tool (SCAT5).
Consistent with the integrity of extended neural networks required for effective spatial orientation and navigation, the findings of our pilot study provide preliminary evidence suggesting that a SRC may affect the ability to familiarize with a spatial surrounding and orient within it.
在这项初步研究中，我们调查了与运动相关的脑震荡 (SRC) 对形成认知图能力的影响，认知图是对环境的心理表示，对于空间定向和导航至关重要。
我们招募了 18 名患有 SRC 的青少年曲棍球运动员，以及 19 名年龄、性别和惯用手与无脑震荡史的曲棍球运动员相匹配。
我们要求参与者执行空间配置任务 (SCT)，这是一种用于定量测量个体形成认知图能力的计算机工具。
我们发现患有脑震荡的运动员在 SCT 上的表现明显逊于对照组（(1,34)=5.82，p=0.021，[Formula: see text]=-0.72），证实 SRC 对形成认知图的能力有负面影响。我们在平均反应时间上未发现组间有显著差异，且参与者在 SCT 上的表现与运动性脑震荡评估工具 (SCAT5) 评定的脑震荡症状之间无显著相关性。
与有效空间定向和导航所需的扩展神经网络的完整性一致，我们的初步研究结果提供了初步证据，表明 SRC 可能会影响熟悉空间环境和在其中定向的能力。
