From: Influence of loud auditory noise on postural stability in autistic children: an exploratory study

Comparison of CoP velocity in the NOISE condition within ASD subgroups. Children were grouped by SPM-2 hearing processing difficulty into moderate (n = 8) and severe (n = 7) subgroups. Panels (a) and (b) show CoP velocity along the AP direction for low- and high-frequency components, respectively; panels (c) and (d) show the same measures along the ML direction. Error bars denote the standard errors of the mean.
