The Effect of Lateral Wedge Insoles on Lower Limb Biomechanics, Muscle Activity and Knee Adduction Moment During Walking and Running
Turkey (Türkiye)30 participantsStarted 2026-06
Plain-language summary
The aim of this prospective, randomized, single-group interventional study is to use quantitative methods to investigate the acute effects of using lateral-wedge insoles on lower extremity biomechanics, muscle activation patterns, and knee adduction moment during walking and running activities in healthy individuals aged 18-40. The primary research questions it seeks to answer are as follows:
* Do lateral wedge insoles cause a significant change in knee adduction moment?
* Do lateral wedge insoles change lower extremity biomechanics during walking and running?
* Do lateral wedge insoles change the activation patterns of lower extremity muscles during walking and running? To compare the effectiveness of lateral wedge insoles, participants will randomly use insoles with 0 (neutral), 5, and 10-degree angles.
Participants will do the following:
* Put on the shoes and insoles provided to you in the motion analysis laboratory and complete the walking and running protocols, each taking 1 minute, on the treadmill.
* While walking at your normal walking speed, step so that your dominant leg is positioned over the force plate.
* Repeat all of this for the insoles at the other two angles.

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
