背景：自闭症谱系障碍 (ASD) 患者的基本运动技能也较差。姿势控制的发展是社交和运动技能的基础。积极使用视觉信息可以促进所有这三个要素。这项研究比较了患有自闭症谱系障碍的成年人和典型发育成年人 (TDA) 对颈部振动引起的姿势错觉的反应。与 TDA 不同，患有自闭症谱系障碍 (ASD) 的成年人不会使用视觉来纠正错觉。方法：该研究在 200 秒的安静姿势期间使用间歇性（15off、5on）后颈振动来诱发姿势错觉。在 TDA 中且仅在视力缺失的情况下，该方案才会导致身体前倾。参与者（12 名 ASD，20 名 TDA）接受了振动和视觉遮挡相结合的四种条件。结果：正如预测的那样，TDA 仅在视力被遮挡时受到姿势错觉的影响（振动条件：视力遮挡 (n=1) p = 0.0001；视力可用 (n=3) p > 0.2466）。无论视力如何，患有 ASD 的成年人都会受到姿势错觉的影响（所有条件 p < 0.0007）。结论：我们的研究结果表明患有自闭症谱系障碍的成年人没有使用视觉信息来控制站立姿势。鉴于现有证据表明自闭症谱系障碍患者通常会处理“视觉感知”，我们的研究结果支持“视觉感知行动”的特定缺陷。这些发现可以解释为什么患有自闭症谱系障碍的人在社交和运动技能方面都会遇到困难，因为两者都需要行动的愿景。进一步的研究需要调查这些视觉学习路径的划分，以便为自闭症谱系障碍提供更具体的干预机会。 (C) 2015 国际广播组织。由爱思唯尔有限公司出版。保留所有权利。
Background: People with autism spectrum disorders (ASDs) also have poorer fundamental motor skills. The development of postural control underlies both social and motor skills. All three elements are facilitated by the active use of visual information. This study compares how adults with ASD and typically developed adults (TDAs) respond to a postural illusion induced using neck vibration. Adults with ASD unlike the TDA, were not expected to correct the illusion using vision. Methods: The study used intermittent (15off, 5on) posterior neck vibration during 200 s of quiet stance to induce a postural illusion. In TDAs and only in the absence of vision this protocol induces a forward body lean. Participants (12 ASD, 20 TDA) undertook four conditions combining vibration and visual occlusion. Results: As predicted, TDA were only affected by the postural illusion when vision was occluded (vibration condition: vision occluded (n=1) p = 0.0001; vision available (n=3) p > 0.2466). Adults with ASD were affected by the postural illusion regardless of the availability of vision (all conditions p < 0.0007). Conclusions: Our findings indicated the adults with ASD did not use visual information to control standing posture. In light of existing evidence that vision-for-perception is processed typically in ASD, our findings support a specific deficit in vision-for-action. These findings may explain why individuals with ASD experience difficulties with both social and motor skills since both require vision-for-action. Further research needs to investigate the division of these visual learning pathways in order to provide more specific intervention opportunities in ASD. (C) 2015 IBRO. Published by Elsevier Ltd.
