30 patients will be included. Dynamic Gait Index and other assessments will be performed twice with a 7-day interval by two evaluators

30 healthy children will be included. Dynamic Gait Index will be performed.

The Dynamic Gait Index (DGI) measures functionality and dynamic balance in walking and stair climbing. The DGI consists of 8 items including normal gait on flat ground, gait with speed changes, gait with horizontal head movements, gait with vertical head movements, gait and pivot turn, gait and step over an obstacle, gait around obstacles and steps up and downstairs. The performance on each item is rated on a 4-point scale ranging from 0 (severe disorder) to 3 (independent walking). The total score is 24.

The Timed Up and Go is a test used to measure mobility and evaluates walking speed, posture control, functional mobility and balance.

Functional Reach Test (FRT) is a static balance test. Measurement is carried out by a tape measure attached to the wall parallel to the floor. The individual was standing parallel to a wall with the feet shoulder wide apart and the shoulders extended at 90 degrees flexion; in this position the third metacarpal head was recorded as the initial position. Then, the patient was asked to reach as forward as (s)he can, without taking a step. Again, the evaluator determined the position of the third metacarpal. The difference in centimeters between the first and second marks determined the FRT value. The FRT was performed three times and average value was taken.
