Acute Effects of Foot Orthoses on Muscle Mechanical Properties in Individuals With Pes Planus
90 participantsStarted 2026-09-01
Plain-language summary
This randomized controlled study will examine the acute effects of a medial arch support and a prefabricated insole on lower-limb muscle mechanical properties and pain in young adults with pes planus. Ninety participants will be allocated in a 1:1:1 ratio to a medial arch support group, an insole group, or a control group. Muscle mechanical and viscoelastic properties will be assessed with MyotonPRO, and pain will be assessed with a visual analog scale.

Exclusion Criteria:
* History of lower-extremity injury or surgery within the past 6 months
* Diagnosis of a rheumatologic or neurological condition that may affect foot joint alignment
* Skin lesions or damage that may prevent the measurements from being performed
* Current use of an orthosis, such as an insole or wedge, to support pes planus

* Unwilling to participate in the study
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Change in Muscle Dynamic Stiffness
Timeframe: Baseline, immediately after the first 30-minute treadmill walking session (T0), and immediately after the second 30-minute walking session following a 30-minute rest period (T1)
2
Change in Muscle Oscillation Frequency
Timeframe: Baseline, immediately after the first 30-minute treadmill walking session (T0), and immediately after the second 30-minute walking session following a 30-minute rest period (T1). T1 measurements will only be performed in the medial arch support and insol
