Brief Summary

The study aims to determine and compare the effects of 8-week intrinsic foot muscle-strengthening exercises and lower extremity strengthening exercises in adolescents with pes planovalgus.

Conditions

Flat Foot

Keywords

exercise; foot posture; foot kinematic

Outcome Measures

Primary Outcomes (4)

• Foot posture assesment

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

  Pre-intervention assesment and after 8-week

• Foot muscle strentgh assesment

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

  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.

  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.

  Pre-intervention assesment and after 8-week

Secondary Outcomes (2)

• Functional assesment

  Pre-intervention assesment and after 8-week

• Quality of life assesment

  Pre-intervention assesment and after 8-week
