About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Single- and Dual-Task Condition AssessmentOther
Participants will perform motor tasks under single-task and dual-task conditions. In the dual-task condition, a concurrent cognitive task will be added to the motor task to increase cognitive load. Performance during these conditions will be assessed to examine the effects of cognitive load on motor performance and postural control. No therapeutic intervention, medication, or device is applied.
| Study group | Role | What they receive |
|---|---|---|
| Autism Spectrum Disorder | The diagnosis of Autism Spectrum Disorder was made by child and adolescent psychiatrists in accordance with the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) diagnostic criteria. Receives: Other: Single- and Dual-Task Condition Assessment | |
| Typically developing child | A control group consisting of children with normal development, matched to the OSB group in terms of age and gender variables, was included. Receives: Other: Single- and Dual-Task Condition Assessment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Postural control performance
Postural control will be assessed using the Nintendo Wii Balance Board under both single-task and dual-task conditions. The mean value of center of pressure sway in the medio-lateral and anterior-posterior directions will be calculated during a 30-second quiet standing task with eyes open. Values will be expressed in millimeters (mm).
Measured: Day 3
Secondary outcomes (3)
Walking Performance
Gait performance will be assessed under single-task and dual-task conditions using a sensor-based mobile gait analysis application. The mean walking speed will be calculated during a 6-meter walking task performed at a self-selected comfortable pace. Walking speed values will be expressed in meters per second (m/s).
Measured: Day 3
Motor Performance
Motor performance will be assessed under single-task and dual-task conditions using the Sit-to-Stand App. During a 30-second sit-to-stand test, the mean vertical power will be calculated based on average vertical velocity normalized to body weight. Mean power values will be expressed in watts (W) and used as an indicator of lower extremity muscle performance.
Measured: Day 3
Childhood Autism Rating Scale
The Childhood Autism Rating Scale (CARS) was used to assess autism spectrum disorder and rate its severity. The CASR is an observation-based assessment tool developed by Schopler, Reichler, and Renner in 1980.The scale consists of 15 items and covers behavioral areas such as social relationships, imitation, emotional responses, physical movements, adaptation, visual and auditory responses, olfactory responses, language communication, and intelligence . In the scoring of the test, 15-29 points indicate no signs of autism, 30-37 points indicate mild to moderate levels, and 38-60 points indicate severe levels of autistic traits .
Measured: Day 1

Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
