Weight-bearing ankle range of motion and ligamentous hyperlaxity in child basketball players
Official title: Assessment of Weight-bearing Ankle Range of Motion Using the Ankle Test and Lower Body Test and Its Relationship With Ligamentous Hyperlaxity in Child Basketball Players Aged 8 to 15 Years
Run by Fundación Universidad Católica de Valencia San Vicente Mártir · NCT07589218 · Data updated 2026-11-12
This study tests how flexible ligaments relate to ankle motion in kids 8–15 who play basketball, to see if hypermobility connects with ankle movement and past injuries.

Is this trial a fit for you?
✓Likely a good fit
Children ages 8 to 15 who play basketball at least 3 hours per week and have parental consent.
✕Probably not a fit
Children without generalized hypermobility or with current injuries affecting measurement may not benefit from the study.

What this trial studies
This cross-sectional observational study measures ankle dorsiflexion under weight-bearing and generalized joint flexibility in children aged 8 to 15 who play basketball. Participants will be classified as hypermobile or non-hypermobile using the Beighton scale, and their ankle dorsiflexion range will be quantified with a dedicated Ankle Test and inclinometer. Associations between hypermobility, ankle motion, and prior injuries will be analyzed to explore potential targets for prevention. Measurements are performed on a single day, with recruitment based on age, sport participation, and consent. The study is conducted at Universidad Católica de Valencia with Benjamín Cuenca Valero as lead sponsor.
Why it matters
Potential benefit: If successful, the findings could inform targeted strategies to prevent ankle injuries in hypermobile children who play basketball.
How similar studies have gone: Prior research has explored Beighton-determined hypermobility and joint range in pediatric populations, supporting the feasibility of this correlational approach.
