Abstract

Objectives

The 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.

Method

We 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.

Results

The 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.

Conclusions

Postural sway in the ASD group did not differ from TD but was maintained from a long-term perspective.

自闭症谱系障碍患者压力中心的波动

【摘要】目的自闭症谱系障碍(ASD)患者静态站立姿势不稳定。然而，原因尚不清楚。我们将利用非趋势波动分析(DFA)对压力中心(COP)的波动进行研究，为进一步阐明压力中心波动的原因做出贡献。方法对16例ASD患者和13例典型发育(TD)患者的COP波动特征进行研究。所有参与者都站在Wii平衡板上70秒，在此期间我们获得了100 Hz的COP数据。睁眼和闭眼各1次。我们得到了轨迹长度、轨迹总长度、外围面积、坐标位置的平均值和标准差，并计算了速度的平均值、标准差、变异系数和alpha指数，作为评价指标。结果两组间COP中外侧、前后方向的位点长度、总长度及外周面积差异无统计学意义。闭眼条件下，ASD组站立位置与每100 Hz移动距离DFA的长期相关强度alpha指数显著大于TD组(p = 0.011)。结论ASD组与TD组的体位偏斜无明显差异，但从长期角度看仍保持不变。

Study participants may include individuals with:Intellectual and developmental disabilitiesGlobal developmental delayCommunication disordersLanguage disordersSpeech sound disordersChildhood-onset fluency disorders (e.g., stuttering)Social (e.g., pragmatic) communication disordersUnspecified communication disordersAutism spectrum disorder (ASD)Attention-deficit/hyperactivity disorder (ADHD), specified and unspecifiedSpecific learning disordersMotor disordersDevelopmental coordination disordersStereotypic movement disorderTic disorders, specified and unspecifiedOther neurodevelopmental disorders, specified and unspecifiedPapers may also include studies of participants with neurodegenerative disorders that lead to a decline in intellectual functioning, including Alzheimer’s disease, amyotrophic lateral sclerosis, Creutzfeldt-Jakob disease, vascular dementia, Lewy body dementia, frontotemporal dementia, corticobasal degeneration, Huntington’s disease, and progressive supranuclear palsy. The journal includes empirical, theoretical and review papers on a large variety of issues, populations, and domains, including but not limited to: diagnosis; incidence and prevalence; and educational, pharmacological, behavioral and cognitive behavioral, mindfulness, and psychosocial interventions across the life span. Animal models of basic research that inform the understanding and treatment of neurodevelopmental disorders are also welcomed. The journal is multidisciplinary and multi-theoretical, and encourages research from multiple specialties in the social sciences using quantitative and mixed-method research methodologies.
