Brief Summary

The aim of this study is to examine the plantar fascia and Achilles tendon thickness and flexibility in individuals with pes planus. Individuals between the ages of 18-45 who have been diagnosed with pes planus by an orthopedist and healthy individuals with similar demographic characteristics will be included in the study as a control group. Demographic information of the individuals will be recorded and clinical evaluations will be made. The foot posture of the individuals participating in the study will be evaluated with the Foot Posture Index, and the degree of flat feet will be evaluated with the Navicular Drop Test. The Achilles tendon and plantar fascia thicknesses of the individuals participating in the study will be measured with ultrasound, and the plantar fascia and Achilles tendon flexibility will be measured with a myotonometer.

Conditions

Pes Planus

Outcome Measures

Primary Outcomes (4)

• Foot Posture Index

  In this study, the Foot Posture Index will be used to evaluate the foot postures of the participants.

  Baseline

• Navicular Drop Test

  The Navicular Drop Test will be administered to measure the amount of drop in the participants' navicular bones.

  Baseline

• Ultrasonographic Evaluation

  Participants' Achilles tendon and plantar fascia thicknesses will be evaluated using a high-resolution ultrasound device.

  Baseline

• Myotonometer

  Participants' plantar fascia and Achilles tendon flexibility will be evaluated using a myotonometer device.
