Recent research was published on postural control and repetitive behaviors in children with autism.    The participants including children with autism spectrum disorder (ASD) and typically developing controls ages 3-16. The center of pressure sway area during quiet, comfortable stance were compared to scores on the Repetitive Behavior Scale-Revised. The results indicated the following:

• increased postural sway in children with ASD
• greater frequency and intensity of restricted, repetitive behaviors were present in the children with ASD
• a positive correlation between postural sway area and presence of restricted, repetitive behaviors
• postural sway area for about half of the ASD subjects scored comparable to TD controls, but the other half scored > 2 SD worse
• motor impaired children were younger and had more repetitive behaviors

The researchers speculate that motor control impairments may characterize a subset of individuals with ASD and that further research is needed.
