Could your pelvis be the key to preventing ankle sprains?
NCT ID NCT07594210
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether pelvic alignment differs between male athletes with and without chronic ankle instability. Researchers will measure ankle stability, balance, and pelvic angles in 38 football players. The goal is to better understand how the pelvis and ankle work together, which could lead to better injury prevention and treatment.

Who is studied
The study will include male competitive football players aged 18 to 35 years. Cases will be defined as players with chronic ankle instability following a history of lateral ankle sprain, while controls will be healthy players without a history of ankle sprain or chronic ankle instability. Participants will be recruited from sports clubs and physiotherapy outpatient departments.

Inclusion Criteria: * Male football players aged between 18 and 35 years (Herzog et al., 2019; Jiang et al., 2022). * A documented history of lateral ankle sprain (LAS) for at least 12 months before the study, with the initial injury resulting in a minimum of one day of weight-bearing restriction. * Self-reported episodes of ankle "giving way" occurring at least twice within the 6-12 months preceding enrollment. * The most recent injury must have occurred more than 3 months before study enrollment. * A perceived sense of the injured ankle being chronically weaker and/or less functional than the contralateral side before the first LAS episode. * A Cumberland Ankle Instability Tool (CAIT) score of less than 24 indicates chronic ankle instability. * For group B: participants with no previous history of ankle sprain. Exclusion Criteria: * Bilateral LAS (Tahoon et al., 2022). * Previous injury, fracture, or surgical intervention involving the spine, pelvis, or lower extremity. * History of low back pain requiring medical or surgical intervention. * Engagement in supervised or unsupervised ankle rehabilitation within one month before the study. * Any LAS occurring within three months before participation. * Leg length discrepancy exceeding 0.5 cm.
