Abstract

Background

Instrumented measurements of postural control provide a more accurate insight into the motor development of children with autism. This study aimed to identify postural control deficits in autistic children during quiet standing before and after transient locomotor task. It was hypothesized that the parameters that characterize the trajectory of center of foot pressure (COP) displacement would be higher in autistic children compared to typically developing children.

Methods

Sixteen autistic children aged 6–10 but without a comorbidity diagnosis, were enrolled in the study group. The control group comprised 16 typically developing peers.

The assessment of the transitional task comprised four different conditions: unperturbed and perturbed transition, stepping up, and stepping down tasks. Analysis of the COP signal was carried out for three distinct phases, i.e., phase 1 – quiet standing before step initiation, phase 2 – transit, and phase 3 - quiet standing until measurement completion.

Findings

The two-way ANOVA with a 2 × 4 factorial design (group × testing condition) revealed a group effect on all posturographic variables in the antero-posterior and medio-lateral directions of phase 1 and in the antero-posterior direction of phase 3. The Bonferroni post-hoc test showed the means of all those variables were significantly higher for the autistic than for typically developing children. Group allocation also had an effect on the time of transit and step length, which turned out to be significantly longer in autistic children compared to healthy peers.

Interpretation

Autistic children show increased postural sway before and after transitional locomotor tasks compared to typically developing children.

The trial was prospectively registered in the Australian and New Zealand Clinical Trials Registry (no. ACTRN12621001113842; date registered: 23.08.2021).

自闭症谱系儿童完成过渡性运动任务前后的姿势控制：病例对照研究

背景通过仪器测量姿势控制，可以更准确地了解自闭症儿童的运动发育情况。本研究旨在确定自闭症儿童在瞬时运动任务前后安静站立时的姿势控制缺陷。假设自闭症儿童的足底压力中心（COP）位移轨迹参数会高于发育正常的儿童。方法研究组招募了 16 名年龄在 6-10 岁、无合并症诊断的自闭症儿童。对照组由 16 名发育正常的同龄人组成。过渡任务的评估包括四种不同的条件：无干扰和有干扰的过渡、上台阶和下台阶任务。结果采用 2 × 4 因子设计（组别 × 测试条件）的双向方差分析显示，在第 1 阶段的前-后和内-外侧方向以及第 3 阶段的前-后方向上，所有后视图形变量都存在组别效应。Bonferroni 事后检验表明，自闭症儿童所有这些变量的平均值都明显高于发育正常儿童。该试验在澳大利亚和新西兰临床试验登记处进行了前瞻性登记（编号：ACTRN12621001113842；登记日期：2021年8月23日）。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
