The aim was to explore the timing and duration of muscle activation during a landing task in children with autism spectrum disorder (ASD), and compare their responses to those of children who are developing typically (TD).
Six children (ages 3-4.5 years), half with ASD, hung from a vertical bar, landed, and reacted to a light cue that signaled the child to run to the right or left or to stay in place. Electromyography and kinematics were recorded and compared between groups.
Children with ASD had more and longer bursts of muscle activation during preimpact. In contrast, children TD displayed more and longer burst of muscle activation during impact.
The results suggest that children with ASD have a less developed landing strategy compared with their peers TD. Further investigation into the neuromuscular components in children with ASD will guide future interventions for this population.
旨在探究自闭症谱系障碍（ASD）儿童在着陆任务期间肌肉激活的时间和持续时间，并将他们的反应与发育正常（TD）儿童的反应进行比较。
六名儿童（3至4.5岁），其中一半患有ASD，他们从垂直杆上悬挂、着陆，并对一个灯光提示做出反应，该提示指示儿童向左或向右跑或原地停留。记录并比较两组之间的肌电图和运动学数据。
ASD儿童在着地前有更多且持续时间更长的肌肉激活爆发。相比之下，TD儿童在着地时表现出更多且持续时间更长的肌肉激活爆发。
结果表明，与TD儿童相比，ASD儿童的着陆策略发育较差。对ASD儿童神经肌肉成分的进一步研究将指导针对这一人群的未来干预措施。
