Abstract    The characteristics of vertical ground reaction force (VGRF) gait patterns in children with autism spectrum disorder (ASD) are poorly understood. The purpose of this study was to identify VGRF gait features that discriminate between children with ASD and the peer control group. The VGRF data were obtained from 24 children with ASD and 24 normal healthy children aged 4 to 12 years. A three-dimensional motion analysis system with eight cameras and two force plates were used to collect VGRF data while subjects performed self-selected speed barefoot walking. Parameterisation techniques were applied to VGRF waveforms to extract the VGRF gait features. Mean significant differences between the two groups were tested using independent samples t-tests and Mann-Whitney U tests. Significant group differences were found for three VGRF gait features. Results indicate that children with ASD exhibit reduced second peak VGRF values, lower push-off rates and higher peak ratios during normal walking. These prominent changes showed that children with ASD had difficulties to support their body weight in terminal stance phase and this condition reflects the gait instability. The finding of this study develop the understanding of VGRF gait patterns that were significantly differentiate between children with ASD and the peer control groups.

چکیده    ویژگی نیروی واکنش عمودی از زمین و یا بیماری قلبی نوزادان درک ناقصی داشته که هدف این مقاله تشخیص نوزادان بیمارASD با مقایسه با گروه کنترل است. داده های بدست آمده از 30 نوزاد مبتلا . 30 نوزاد سالم در سنین 4 الی 12 سال مقایسه گردید. جهت جمع آوری داده ها با 8 دوربین و 2 صفحه نیرو برای بررسی حرکت سه بعدی با پاه برهنه راه رفتن مورد بررسی قرار گرفت. با روش تعیین پارامترها حرکت موجی بررسی می شود. میانگین اختلاف بین دو گروه بروش آزمون های تی و یو بطور مستقل بررسی خواهند شد. اختلاف فاحشی برا ی چهار ویژه گیVGRF مشخص گردید.نتایج نشان میدهد که نوزادان مبتلا بهASD کاهش قابل ملاحظه ای در ظاهر شدن زود رس پیک دوم بطور ضعیف VGRF مشاهده گردید. همچنین نسبت بیشتری با دو پیک VGRF در طول راه رفتن با سرعت عادی داشته است. اختلاف مشهودی بین نوزادان سالم و نوزادان مبتلا بهASD برای نگهداری وزن بدن در طول مسیر پیاده روی و ناپایداری آنها ملاحظه گردید. نتایج مطالعات منجر به درک VGRF گردید. اختلاف قابل ملاحظه ای بین گروه نوزاذان مبتلا به ASD با گروه سالم مشاهده گردید.
