Participants will perform three balance and functional mobility assessments, including the Pediatric Balance Scale, Timed Up and Go Test, and 10-Second Sit-to-Stand Test. Following the initial assessment, participants will wear the orthotic garment and repeat the same assessments.

Participants will initially perform the balance and functional mobility assessments while wearing the orthotic garment. After removal of the garment, the Pediatric Balance Scale, Timed Up and Go Test, and 10-Second Sit-to-Stand Test will be repeated under the same conditions.

Theratogs is a dynamic orthotic garment, made of a "breathable", lightweight, self-adhesive Velcro fabric. It provides a gentle passive force for correcting imbalances or alignments through a combined system of the trunk and lower limbs, along with a system of customized external straps. It is worn over the skin under clothing or over a diaper. The patented soft foam material gently grips the user's soft tissues to create biomechanical changes that are essential for positive outcomes. A variety of lengths, back sizes, stiffness diameters, and placement options optimize the therapeutic and orthotic effects.

The Timed Up and Go (TUG) test evaluates functional mobility. The test requires a chair with armrests and back support, a measuring tape, adhesive tape, and a stopwatch. The time required for the participant to stand up from the chair, walk a distance of three meters (with or without assistive devices), turn around, return, and sit down again is recorded. The TUG test is considered a valid and highly reliable tool (ICC = 0.99) for evaluating functional mobility in children with CP.

The 10 Meter Walk Test (10MWT) evaluates functional mobility by measuring walking speed. Participants walk at their normal pace along a 14-meter walkway with or without assistive devices. A stopwatch is used to record the time required to complete a 10-meter distance, excluding the first and last two meters to allow for acceleration and deceleration. The test demonstrates high test-retest reliability and high correlation with gross motor function in children with CP.

The Pediatric Balance Scale (PBS) is a modified version of the Berg Balance Scale designed to assess functional balance skills in children with mild to moderate motor impairments. The scale consists of 14 balance-related items scored from 0 (lowest function) to 4 (highest function), with a maximum score of 56 and a minimum score of 0 . The PBS has been translated into Greek and is considered a reliable and valid tool for assessing functional balance in children with CP.
