Examining foot structure and flexibility in flat feet

Investigation of Plantar Fascia and Achilles Tendon Thickness and Flexibility in Individuals With Pes Planus

Observational Hacettepe University · NCT06987422

This study is testing the thickness and flexibility of certain foot structures in people with flat feet and comparing them to those with normal feet to see how they differ.

What this trial studies

This study investigates the thickness and flexibility of the plantar fascia and Achilles tendon in individuals diagnosed with pes planus, also known as flat feet. Participants aged 18 to 45 will be recruited, including those with pes planus and a control group of healthy individuals. Clinical evaluations will be conducted, including demographic data collection, foot posture assessment using the Foot Posture Index, and the Navicular Drop Test to evaluate the degree of flat feet. Ultrasound will be utilized to measure tendon thickness, while flexibility will be assessed with a myotonometer.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18 to 45 diagnosed with pes planus by a physician.

Not a fit: Patients with severe visual impairment, neurological disorders, or those who have undergone lower extremity surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of foot mechanics in pes planus, potentially leading to improved treatment strategies.

How similar studies have performed: While similar studies have explored foot mechanics, this specific investigation into the relationship between tendon thickness and flexibility in pes planus is relatively novel.
