What is being measured
The primary outcome is the main question the study is designed to answer.
Foot posture assesment
Foot Posture Index 6 and navicular drop will be used for assesing the foot pronation.
Measured: Pre-intervention assesment and after 8-week
Foot muscle strentgh assesment
Toe muscle strength will be assessed through the utilization of a handheld dynamometer.
Measured: Pre-intervention assesment and after 8-week
Performance and dynamic balance assesment
Front jump test and star excursion balance test will be performed by participants.
Measured: Pre-intervention assesment and after 8-week
3D gait analysis
The kinetic/kinematic analysis of the foot and the lower extremity will be conducted using a motion capture system, specifically employing the Oxford Foot Model and the Plug-in Gait Model.
Measured: Pre-intervention assesment and after 8-week
Secondary outcomes (2)
Functional assesment
The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) will be utilized for function-related aspect.
Measured: Pre-intervention assesment and after 8-week
Quality of life assesment
Pediatric Quality of Life Inventory (PedsQL) will be utilized for the assessment of participants' quality of life status.
Measured: Pre-intervention assesment and after 8-week
