Autism is associated with differences in sensory processing and motor coordination. Evidence from electroencephalography suggests individual perturbation evoked response (PER) components represent specific aspects of postural disturbance processing; P1 reflects the detection and N1 reflects the evaluation of postural instability. Despite the importance of these cortical responses to postural control, PERs to a perturbation in adults with autism spectrum disorder (ASD) have yet to be reported. The aim was to compare PERs to visual perturbation under varied postural stability conditions in adults with and without ASD. This study is the first to report that while the assessment of postural set is intact, adults with ASD use more cortical resources to integrate and interpret visual perturbations for postural control.
自闭症与感官处理和运动协调的差异有关。脑电图证据表明，个体扰动诱发反应 (PER) 成分代表姿势干扰处理的特定方面；P1 反映了检测，而 N1 反映了对姿势不稳定的评估。尽管这些皮质反应对姿势控制很重要，但自闭症谱系障碍 (ASD) 成人的 PER 尚未被报道。目的是比较 ASD 成人和非 ASD 成人在不同姿势稳定性条件下对视觉扰动的 PER。这项研究首次报告称，虽然姿势设定的评估是完整的，但 ASD 成人使用更多的皮质资源来整合和解释视觉扰动以进行姿势控制。
