Several studies have investigated cognitive-communication disorders affecting oral expression skills following TBI but very few have dealt with reading comprehension abilities. The current study aims to measure reading comprehension and speed of reading in adults with uncomplicated and complicated mild traumatic brain injury (TBI) and to determine which demographic and TBI-related variables are predictive of their performance.
The performances of three groups of participants were compared on the Chapman-Cook Speed of Reading Test (CCSRT). The CCSRT was administered in an acute care setting to 85 hospitalized participants with mild TBI showing traumatic cerebral lesions (complicated mild TBI), to 15 hospitalized participants with uncomplicated mild TBI (no cerebral lesions) and to 68 adults without TBI. Linear regression analyses were performed to determine which variables among sex, age, education, TBI severity (measured by the Glasgow Coma Scale score), speed of processing skills, and site of cerebral lesions significantly predicted CCSRT performances.
The control group showed a lower percentage of errors than both TBI groups. On the total score of the CCSRT, the uncomplicated and complicated TBI groups performed worse than the control group. Moreover, as age and speed of processing skills increased, and education decreased, the odds of having a lower score on the CCSRT increased.
These findings suggest that reading abilities are compromised after mild TBI. Furthermore, the CCSRT may be a useful bedside tool for clinicians who work with individuals with mild TBI.
有几项研究调查了 TBI 后影响口语表达技能的认知-交流障碍，但很少有研究涉及阅读理解能力。本研究旨在测量无并发症和复杂轻度创伤性脑损伤 (TBI) 成人的阅读理解和阅读速度，并确定哪些人口统计学和 TBI 相关变量可预测他们的表现。
比较了三组参与者在查普曼-库克阅读速度测试（CCSRT）中的表现。CCSRT 在急性护理环境中对 85 名有创伤性脑损伤（复杂轻度 TBI）的住院轻度 TBI 患者、15 名无并发症轻度 TBI（无脑损伤）的住院患者和 68 名无 TBI 的成年人进行了测试。进行线性回归分析，以确定性别、年龄、教育程度、TBI 严重程度（格拉斯哥昏迷量表评分）、加工速度技能和脑损伤部位等变量中哪些能显著预测 CCSRT 表现。
对照组的错误率低于两组 TBI 患者。在 CCSRT 的总分上，无并发症和复杂 TBI 组的表现均不如对照组。此外，随着年龄和加工速度技能的提高，以及教育程度的降低，CCSRT 得分较低的可能性增加。
这些发现表明，轻度 TBI 后阅读能力受损。此外，CCSRT 可能是临床医生治疗轻度 TBI 患者的有用床边工具。
