我们调查了感觉统合失调的性质，在姿势控制的年轻成年人与ASD。姿势控制进行了评估，在一个固定的环境中，并在三个环境中，感觉信息从视觉，本体感受或两者兼而有之的身体摇摆是不准确的。此外，在每个通道内使用两个级别的不准确信息（增益1和1.6）。当来自两个渠道的信息都不准确时，ASD参与者表现出更大的姿势摇摆。此外，对照参与者在增益1.6时的椭圆面积与ASD参与者在增益1时的椭圆面积相同，反映了ASD的高反应性。我们的研究结果为姿势相关感觉信息的高反应性提供了证据，这反映了ASD中的一般而非通道特异性感觉整合障碍。
We investigated the nature of sensory integration deficits in postural control of young adults with ASD. Postural control was assessed in a fixed environment, and in three environments in which sensory information about body sway from visual, proprioceptive or both channels was inaccurate. Furthermore, two levels of inaccurate information were used within each channel (gain 1 and 1.6). ASD participants showed greater postural sway when information from both channels was inaccurate. In addition, control participants' ellipse area at gain 1.6 was identical to ASD participants' at gain 1, reflecting hyper-reactivity in ASD. Our results provide evidence for hyper-reactivity in posture-related sensory information, which reflects a general, rather than channel-specific sensory integration impairment in ASD.
