The Interaction Between Executive Attention and Postural Control in Dual-Task Conditions: Children With Cerebral Palsy

Cognitive task: temporal sequence of the visual working memory task presentation in seconds and milliseconds.

Group means ±1 SD of COP displacement in (A) the AP range and (B) RMS AP velocity. Abbreviations: ACP, ataxic CP; D, dual; NS, narrow stance; S, single; SCP, spastic CP; WS, wide stance.

Group means ±1 SD of COP displacement in (A) the ML range and (B) RMS ML velocity.

Individual COP tracings (in meters) in 1 block of trials (38s), in narrow stance, single- versus dual-task condition in: (A) typically developing older child; (B) typically developing young child; (C) child with spastic cerebral palsy; and (D) child with ataxic cerebral palsy. NOTE. The x axis is the AP direction; the y axis is the ML direction.

Titration curve for (A) number of colored shapes recalled with a 70% accuracy rate: typically developing older children (), typically developing young children (), and children with CP (); and (B) children with spastic CP () and children with ataxic CP ().
