Determination of the Degree of Dynamic Stability of the Foot in Single-leg Support in Relation to the Foot Posture Index in Judokas

Spain45 participantsStarted 2023-03-01

Plain-language summary

The goal of this observational study is to examine the relationship between foot type and dynamic stability (balance while standing on one leg) in judo athletes. Judo requires excellent balance to perform techniques effectively and avoid injuries. However, there is limited scientific knowledge about how foot posture affects balance in judokas. The main questions this study aims to answer are: * Does foot type (neutral, pronated, or supinated) affect dynamic stability in judokas? * Are there differences in balance between male and female judokas? * Does injury history affect dynamic stability? * Is there a difference in balance between the dominant and non-dominant foot? Participants in this study will: * Have their foot type assessed using the Foot Posture Index (FPI-6), a clinical tool that evaluates foot alignment * Perform the Y Balance Test, which measures how far they can reach in three directions while standing on one leg * Complete a questionnaire about their training history, injuries, and demographic information All assessments will be conducted in the participants' judo training facilities (tatami) during a single session. Researchers will compare three groups of judokas (those with neutral, pronated, and supinated feet) to see if foot type influences balance performance. This information may help coaches and healthcare professionals better assess athletes, prevent injuries, and improve sports performance in judo.

Inclusion Criteria: * Federated judo athletes between 15 and 40 years of age. * Minimum of 3 years practicing judo. * At least 2 judo training sessions per week. * Ability to understand and follow study instructions. * Signed informed consent (and parental consent for minors, if applicable). Exclusion Criteria: * Presence of any systemic disease that may cause morphological or biomechanical alterations of the lower limbs. * Current biomechanical limitations of the lower limbs that prevent safe performance of the Y Balance Test. * History of recent lower limb surgery or spinal surgery that may interfere with balance assessment. * Refusal to undergo measurements or to have data collected at the time of evaluation.

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.
