Treatment and study plan

Foot exercise

Other

This group will engage in an 8-week foot intrinsic strengthening training

Lower Extremity Exercise

Other

This group will engage in an 8-week lower extremity strengthening training

Primary outcomes

  1. Foot posture assesment

    Time frame: Pre-intervention assesment and after 8-week

    Foot Posture Index 6 and navicular drop will be used for assesing the foot pronation.

  2. Foot muscle strentgh assesment

    Time frame: Pre-intervention assesment and after 8-week

    Toe muscle strength will be assessed through the utilization of a handheld dynamometer.

  3. Performance and dynamic balance assesment

    Time frame: Pre-intervention assesment and after 8-week

    Front jump test and star excursion balance test will be performed by participants.

  4. 3D gait analysis

    Time frame: Pre-intervention assesment and after 8-week

    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.

Secondary outcomes

  1. Functional assesment

    Time frame: Pre-intervention assesment and after 8-week

    The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) will be utilized for function-related aspect.

  2. Quality of life assesment

    Time frame: Pre-intervention assesment and after 8-week

    Pediatric Quality of Life Inventory (PedsQL) will be utilized for the assessment of participants' quality of life status.
