AI analyzes Footballers' balance to predict ankle injuries
NCT ID NCT07421492
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how amateur football players with chronic ankle instability balance differently from those without it. Researchers will use special balance tests and machine learning to see if they can identify at-risk players just from their movement data. The goal is to create a more objective way to assess injury risk, rather than relying only on questionnaires.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better, objective ways to identify football players at risk of ankle injuries, helping coaches and trainers prevent them.
- What could go wrong
- This is a small, early-stage study with only 28 participants. The machine-learning models may not work well in larger, more diverse groups of athletes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Male amateur football players with at least 2 years of competitive participation and ≥5 years of regular sports activity * Weekly football training volume of at least 3 hours * For the CAI group: history of ≥1 significant lateral ankle sprain occurring ≥12 months before testing that caused pain, swelling, and temporary interruption of sports participation * Presence of ≥2 episodes of giving-way or perceived ankle instability within the previous 6 months * CAIT score ≤24 for classification as chronic ankle instability * For the control group: no history of ankle sprain or perceived ankle instability and CAIT score ≥25 * Participants free from ankle pain and acute inflammation at the time of assessment Exclusion Criteria: * History of lower-extremity fracture or surgical intervention * Musculoskeletal injury of the knee, hip, or spine within the last 3 months * Diagnosed vestibular disorder or systemic balance impairment unrelated to the ankle * Active ankle pain or acute inflammatory symptoms at the time of testing * Any cardiovascular or systemic disease limiting safe participation in testing
