Dysfunctions in body processing have been documented in adults with brain damage, while limited information is available for children. This study aimed to investigate body processing in children and adolescents with traumatic brain injury (TBI) (N = 33), compared to peers with typical development. Two well-known computerized body-representation paradigms, namely Visual Body Recognition and Visuo-spatial Imagery, were administered. Through the first paradigm, the body inversion and composite illusion effects were tested with a matching to sample task as measures of configural and holistic processing of others' bodies, respectively. The second paradigm investigated with a laterality judgement task the ability to perform first-person and object-based mental spatial transformations of own body and external objects, respectively. Body stimuli did not convey any emotional contents or symbolic meanings. Patients with TBI had difficulties with mental transformations of both body and object stimuli, displaying deficits in motor and visual imagery abilities, not limited to body processing. Therefore, cognitive rehabilitation of body processing in TBI might benefit from the inclusion of both general training on visuo-spatial abilities and specific exercises aimed at boosting visual body perception and motor imagery.
身体加工功能障碍在脑损伤的成年人中已有记录，但关于儿童的信息有限。本研究旨在调查创伤性脑损伤（TBI）儿童和青少年（N = 33）的身体加工情况，并与发育正常的同龄人进行比较。采用了两种著名的计算机化身体表征范式，即视觉身体识别和视觉空间意象。通过第一种范式，分别用样本匹配任务测试身体倒置和合成错觉效应，作为对他人身体的构型和整体加工的测量。第二种范式通过横向判断任务分别研究了对自己身体和外部物体进行第一人称和基于物体的心理空间转换的能力。身体刺激不传达任何情感内容或象征意义。TBI患者在身体和物体刺激的心理转换方面存在困难，表现出运动和视觉意象能力的缺陷，而不仅限于身体加工。因此，TBI患者身体加工的认知康复可能受益于包括视觉空间能力的一般训练和旨在增强视觉身体感知和运动意象的特定练习。
