Perceptions about the causes and consequences of concussion, and individual representations and interpretations of these factors, can influence the post-concussive recovery process. The goal of this project was to synthesize evidence on perceptions related to concussions as experienced by children, adolescents, and parents, and to evaluate how these perceptions impact post-concussive recovery in physical, behavioural, cognitive, and psychological domains. We undertook a systematic review based on the Cochrane Handbook, conducting a comprehensive search of six databases and Google Scholar. Duplicate, independent screening was employed and the quality of studies was assessed using the Mixed Methods Appraisal Tool (MMAT). A total of 1552 unique records were identified, and six records (5 scientific articles and 1 thesis, published between 1990 and 2018; N = 26 to 412, age range from 2 to 18 years) were included. Perceptions about concussions were assessed differently between studies, with a range in types of measures and respondents. Some evidence suggested that perceptions could negatively impact concussion recovery, mostly post-concussive symptoms. However, results were not consistent between studies and the methodological quality was variable (and often low). There is limited evidence of the impact of perceptions of children, adolescents, and their parents on concussion recovery. Priorities for future research investigating concussion recovery should include recruiting representative samples, accounting for potential confounders, and measuring perceptions in children, adolescents and parents using validated measures. Higher quality studies are needed to better understand the role of perceptions in concussion recovery and to inform clinical care.

知觉如何影响儿童期和青少年期脑震荡的恢复：系统评价。

对脑震荡的原因和后果的认知，以及对这些因素的个体表示和解释，都可能影响脑震荡后的恢复过程。该项目的目的是综合有关儿童，青少年和父母所经历的脑震荡相关知觉的证据，并评估这些知觉如何影响脑震荡后身体，行为，认知和心理领域的恢复。我们根据Cochrane手册进行了系统的审查，对六个数据库和Google Scholar进行了全面搜索。采用重复的独立筛选，并使用混合方法评估工具（MMAT）评估研究质量。总共确定了1552条唯一记录，其中有6条记录（5条科学文章和1篇论文，ñ = 26至412，年龄范围从2至18岁）。在研究之间对脑震荡的看法进行了不同的评估，包括各种类型的测量方法和受访者。一些证据表明，知觉可能会对脑震荡的恢复产生负面影响，主要是脑震荡后的症状。但是，研究之间的结果不一致，并且方法学质量参差不齐（并且经常很低）。关于儿童，青少年及其父母的认知对脑震荡恢复的影响的证据有限。未来研究脑震荡恢复的研究重点应包括招募代表性样本，考虑潜在的混杂因素，以及使用经过验证的措施来测量儿童，青少年和父母的知觉。
