Praxis refers to the ability to plan and execute skilled movements, and children with Autism Spectrum Disorder (ASD) often show impairments in this area. These deficits can affect imitation, motor planning, gesture production, and daily adaptive behaviors.
## Key Impairments
Children with ASD typically struggle more with somatopraxis (body-focused movements) and postural praxis than visuopraxis (visually guided actions). Studies highlight weaknesses in imitating gestures, using tools, and sequencing actions, often linked to inferior parietal lobule connectivity issues. These challenges compound social communication difficulties, as praxis has a social component like understanding intent in gestures.
## Intervention Effects
Movement-based interventions, such as creative "Play" activities or general exercise, reduce errors in praxis tests like the Sensory Integration and Praxis Test (SIPT) subtests for bilateral motor coordination and postural praxis. All groups in a 2022 trial (Play, Move, Create) improved postural imitation, but only rhythmic Play enhanced bilateral coordination; telehealth matched face-to-face results. Ideational praxis also correlates with better play development and adaptive leisure skills.
## Neural and Developmental Links
ASD praxis issues relate to altered brain connectivity, particularly in frontal-parietal networks needed for intention-to-action translation. Early facilitation—scaffolding regulation without handing ideas—supports praxis across emotional developmental capacities, avoiding rote practice that bypasses planning. Deaf children with ASD show added gesture imitation deficits.
