Fluctuations of the Center of Pressure in Autism Spectrum Disorder
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.
期刊介绍：
Advances in Neurodevelopmental Disorders publishes high-quality research in the broad area of neurodevelopmental disorders across the lifespan. 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.
