目的自闭症谱系障碍（ASD）患者的静态站立位不稳定。但是，原因尚未明确。我们将探讨波动的压力中心（COP）的趋势波动分析（DFA），并有助于阐明的原因在future.MethodWe调查了波动的特点，在COP在16个人与ASD和13个人与典型的发展（TD）。所有参与者站在Wii平衡板上70秒，在此期间，我们获得了100 Hz的COP数据。闭眼和闭眼条件各进行一次。获得轨迹长度、轨迹总长度、外周面积、坐标位置的平均值和标准差，并根据所获得的数据计算速度的平均值、标准差、变异系数和α指数，作为评价指标。以及COP的外周区域，发现组间无显著差异。阿尔法指数显示的力量的长期相关性的站立位置的DFA的移动距离每100 Hz的ASD组显着大于TD组（p= .011）在前后方向下的眼睛闭合condition.ConclusionsPostural摇摆ASD组并没有从TD不同，但保持从长期的角度来看。
ObjectivesThe static standing position of autism spectrum disorder (ASD) is unstable. However, the cause has not been clarified. We will investigate the fluctuation of center of pressure (COP) by detrended fluctuation analysis (DFA) and contribute to the elucidation of the cause in the future.MethodWe investigated the characteristics of fluctuations in the COP in 16 individuals with ASD and 13 individuals with typical development (TD). All participants stood on a Wii Balance Board for 70 s during which time we obtained COP data at 100 Hz. The eyes-open and eyes-closed conditions were performed once each. We obtained the locus length, total locus length, outer peripheral area, and the mean value and standard deviation of the coordinate position, and also calculated the mean value, standard deviation, coefficient variability, and alpha index of velocity from the acquired data, which we used as evaluation indices.ResultsThe locus lengths in the mediolateral and anteroposterior directions and the total length, as well as the outer peripheral area of the COP, found no significant differences between the groups. The alpha index showing the strength of long-term correlations of the standing position by DFA of moving distance per 100 Hz in the ASD group was significantly larger than that in the TD group (p= .011) in the anteroposterior direction under the eyes-closed condition.ConclusionsPostural sway in the ASD group did not differ from TD but was maintained from a long-term perspective.
