Brief Summary

The foot plays a critical role in movement and postural control, with toe flexor strength linked to gait, performance, and stability. While these relationships are well studied in adults, evidence in adolescents is limited. Pes planovalgus may reduce push-off capacity and weaken postural responses through decreased toe muscle strength. This study aims to examine the relationship between foot posture, toe flexor strength, and balance, focusing on anterior-posterior center of pressure changes in adolescents.

Conditions

Adolescent; Foot Posture Index Score; Toe Flexor Strength; Flat Foot Acquired Bilateral (Pes Planus); Balance Assessment

Keywords

flat foot; toe muscle strength; balance; center of pressure

Outcome Measures

Primary Outcomes (4)

• Balance

  Anterior-posterior (AP) center-of-pressure displacement and velocity will be calculated by collecting data with 2 force plates.

  Baseline

• Foot Posture

  Foot posture index - 6 will be used to determine foot posture of participants.

  Baseline

• Toe muscle strength

  Hallux and lesser toe flexor muscle strength will be assessed with a dynamometer while seated and pushing against it.

  Baseline

• Navicular drop

  Navicular drop will be used to assess foot posture.
