The Upper Limb Short Questionnaire was administered by the researcher in face-to-face sessions with the children and their caregivers.

The lower extremity functions and ambulation levels of the children were evaluated by the researcher using the Vignos Scale.

The Brooke Upper Extremity Functional Rating Scale and ABILHAND-Kids were used to evaluate children's upper extremity functions.

The Upper Limb Short Questionnaire consists of questions about UE function (5 items), pain (6 items), and stiffness (3 items). ULSQ can be used as an identifier of arm-hand limitations during the clinical investigation. The total score changes between 0 and 14. Lower scores present children have more problems in the upper extremities.

That evaluates upper extremity function according to 18 different activities performed by children. The total score calculates by summing the grades that children get from each item and change between 0 and 36. Lower scores present lower ability while higher scores indicate higher ability of the hand/upper extremity in the ABILHAND-Kids.

This scale classifies patients' walking abilities in 10 grades ranging from 1 to 10. At the first level, the patient can walk and climb the steps without assistance, but at the last level, patient is confined to bed.

It classifies upper extremity function with 6 different levels based on the children's upper extremity movements. Level 1 means patient can start the movement with the arms at the sides and fully joins the hands above the head, Level 6 is defined as unable to raise their hands to their mouths and cannot use their hands functionally.
