Verbal fluency is a neuropsychological measure commonly used to examine cognitive-linguistic performance as reported in pediatric TBI literature. We synthesized the scholarly literature of verbal fluency performance in pediatric TBI and estimated the effects of TBI according to: (i) type of verbal fluency task (phonemic or semantic), (ii) severity of TBI, and (iii) time post-injury. Meta-analysis revealed that childhood TBI negatively impacted phonemic fluency and semantic fluency and that effect sizes were larger for children with more severe TBI. The negative effect of TBI was evident across time post injury within each level of severity. Verbal fluency tasks are efficient indicators of potential underlying impairments in lexical knowledge and executive functioning in children with TBI regardless of severity of injury or time post injury. Future research employing verbal fluency tasks are encouraged to explore if age at injury differentiates semantic versus phonemic fluency outcomes across severity levels.

语言流畅性是一种神经心理学测量，通常用于检查儿童 TBI 文献中报告的认知语言表现。我们综合了儿科 TBI 语言流畅性表现的学术文献，并根据：（i）语言流畅性任务的类型（音素或语义），（ii）TBI 的严重程度和（iii）受伤后的时间来估计 TBI 的影响. 荟萃分析显示，儿童 TBI 对音素流畅度和语义流畅度产生负面影响，并且对更严重的 TBI 儿童影响更大。TBI 的负面影响在每个严重程度的损伤后时间上都很明显。无论受伤的严重程度或受伤后的时间如何，语言流畅性任务都是 TBI 儿童词汇知识和执行功能潜在潜在损害的有效指标。
