Balance, TMJ, Social Adaptive Assessment in Individuals With Autism Spectrum Disorder

The dual-task abilities of individuals will be assessed by adding motor and cognitive tasks to the 10-Meter Walk Test. The tasks given to participants are as follows: Single Motor Task (comfortable walking): The individual is asked to walk at a normal pace, and the time is recorded. Motor-Motor Dual Task: The individual carries a half-filled water bottle in each hand while walking, and the time is recorded. Motor-Cognitive Dual Task (mental): The individual counts backward from 10 in increments of one while walking, and the time is recorded. Motor-Cognitive Dual Task (memory): The individual is asked to recall three previously mentioned words while walking, and the time is recorded.

Functional balance will be assessed using the Timed Up and Go (TUG) test. The TUG test measures the time it takes for an individual to stand up from a chair upon the "ready, go" signal, walk a distance of 3 meters, turn around, walk back to the chair, and sit down again. The TUG test is a reliable and sensitive measure of balance and functional mobility in children. At the beginning of the test, participants will be seated on an armless chair with their hips and knees flexed at approximately 90 degrees and their feet flat on the ground. The children will be instructed to stand up from the chair, walk as quickly as possible, touch a target on the wall, walk back, and sit down again.

Adaptive behavior will be evaluated using the Vineland Adaptive Behavior Scales. This is a parent interview designed to assess functionality in daily life. Specifically, adaptive behavior is evaluated in four domains: Communication, Daily Living Skills, Socialization, and Motor Skills. The Vineland scales are known for their reliability and up-to-date validity. They have been reported to be sensitive to the challenges faced by children with Autism Spectrum Disorder (ASD).

Cervical posture will be evaluated using the Android-based PostureScreen Mobile application (version 8.5, developed by Posture Co. Inc., USA). This application assesses the static posture of individuals. After determining reference points, the application draws reference lines and records postural deviations. At least two photos of each participant will be taken for the assessment. Participants should not wear clothing items that cover the neck (e.g., scarves, shawls). While the primary focus of the application is to assess postural deviations, it also includes a dental evaluation feature. The validity and reliability of the application have been established in previous studies. In addition to using the application, the posture of individuals will also be evaluated through observational analysis, and the findings will be documented.

The TMJ will be evaluated using the Helkimo Clinical Craniomandibular Index. This index consists of five subcategories: pain during muscle palpation, pain during TMJ palpation, pain during mandibular functions, TMJ functions (sounds, gliding during maximum opening, dislocation and/or locking), and the mandibular range of motion. Each subcategory is scored as 0, 1, or 5, resulting in a total score ranging from 0 to 25. As this index is based on performance measurements, there is no Turkish validity and reliability study for it. However, a prevalence study using this index was conducted in Turkey by Üner et al. to evaluate its applicability within the Turkish population.
