Approximately 30% of individuals with a sport-related concussion present with postural instability. Multiple clinical balance tests exist to diagnose postural instability; yet little is known about the potential relationship between these type of postural assessments and cognition post-concussion.
The purpose of the current study was to assess the relationship between the Romberg test, the Wii Fit basic balance test (WBBT), and the composite scores on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) test in a sample of athletes with concussions.
Fifty five post-concussed athletes (40 males) completed the Romberg test (RT) (-/+), the WBBT, and ImPACT test. WBBT performance was operationalized as the number of successfully completed trials (of 5 trials of increasing difficulty) within 30 seconds. Pearson's and point-biserial correlations examined univariate associations among the variables.
The RT and WBBT were not significantly related ( = - 0.029, = 0.832). The RT weakly correlated with ImPACT impairment scores ( = 0.26, = 0.041), whereas WBBT the number of trials did not ( = - 0.20, = 0.155). The RT scores were significantly correlated with ImPACT Visual Processing Speed Score ( = 0.27, = 0.036) and Reaction Time score ( = 0.34, = 0.006). In contrast, WBBT trials were significantly correlated with the ImPACT Visual Memory Score ( = - 0.41, = 0.003).
These results suggest that the WBBT and RT assess unique aspects of postural control. The RT may relate directly to single sensory cognitive and motor processing, while the WBBT may relate to multi-sensory visually driven cognitive and motor processing.
Clinical balance tests could point to different cognitive impairments post-concussion.
约30%的运动相关性脑震荡患者存在姿势不稳。有多种临床平衡测试可用于诊断姿势不稳；然而，对于这类姿势评估与脑震荡后认知之间的潜在关系，人们了解甚少。
本研究旨在评估在脑震荡运动员样本中，罗姆伯格试验、Wii Fit基本平衡测试（WBBT）与即时脑震荡评估和认知测试（ImPACT）的综合得分之间的关系。
55名脑震荡后运动员（40名男性）完成了罗姆伯格试验（RT）（睁眼/闭眼）、WBBT和ImPACT测试。WBBT的表现通过在30秒内成功完成的试验次数（共5次难度递增的试验）来衡量。采用皮尔逊相关性分析和点二列相关性分析来检验变量之间的单变量关联。
RT与WBBT无显著相关性（r = - 0.029，p = 0.832）。RT与ImPACT损伤得分弱相关（r = 0.26，p = 0.041），而WBBT的试验次数与之无相关性（r = - 0.20，p = 0.155）。RT得分与ImPACT视觉处理速度得分显著相关（r = 0.27，p = 0.036）和反应时间得分显著相关（r = 0.34，p = 0.006）。相比之下，WBBT试验次数与ImPACT视觉记忆得分显著相关（r = - 0.41，p = 0.00）。
这些结果表明，WBBT和RT评估姿势控制的不同方面。RT可能直接与单一感觉认知和运动处理相关，而WBBT可能与多感觉视觉驱动的认知和运动处理相关。
临床平衡测试可能指向脑震荡后不同的认知损伤。
