Single-Dual Task Performance in Children With Autism Spectrum Disorder and Typically Developing Children

Comparing Single and Dual Task Effects in Children With Autism Spectrum Disorder and Typically Developing Children

This study aims to compare the effects of single-task and dual-task conditions on motor performance and postural control in children with Autism Spectrum Disorder (ASD) and typically developing children. Participants' performance under single-task and dual-task conditions involving cognitive load will be evaluated to examine how cognitive demands affect physical task performance in both groups.

Inclusion Criteria:

• Autism Spectrum Disorder (ASD) Group:
• Aged between 5 and 16 years
• Diagnosed with mild to moderate Autism Spectrum Disorder based on Childhood Autism Rating Scale (CARS) scores
• Ability to understand basic visual, auditory, and verbal instructions
• Sufficient cognitive capacity to follow dual-task instructions

Typically Developing Control Group:

• Age- and sex-matched with the ASD group
• No history of neurological, psychiatric, sensory, orthopedic, or developmental disorders
• No acute or chronic medical conditions
• No pain complaints during assessment
• Written informed consent obtained from a legal guardian

Exclusion Criteria:

Both Groups:

• History of neurological disorders, epilepsy, or seizures
• Orthopedic or musculoskeletal conditions affecting balance
• Visual or hearing impairments (except corrected vision or hearing with glasses or hearing aids)
• Use of assistive devices for walking or balance
• Use of medications affecting balance or motor performance
• Presence of comorbid psychiatric disorders
• Inability to cooperate adequately during assessment
• Absence from more than two consecutive assessment sessions
• Participation in another intervention program during the study period
