Brief summary
The purpose of this study was to analyze if a low ankle dorsiflexion range is associate with dynamic knee valgus in youth basketball players.
Detailed description
Cross-sectional study. Ankle dorsiflexion range of motion was assessed by the Weight-bearing lunge test and the dynamic knee valgus by the Single leg squat test. The participants were basketball players who belonged to youth basketball de-velopmental teams in the under-12 (U12), under-14 (U14), under-16 (U16) and under-17 (U17) categories. All participants were recruited by means of simple random sampling from the Catalan Basketball Federation during the 2018-2019 season. The participants were classified according to gender and age as stipulated by the rules determined an-nually for the respective official competitions. The study was carried out in the facilities of each club. The inclusion criteria were being age \>12 and ≤17 at testing and actively competing during the study. Subjects were excluded if they had sustained any type of injury in the lower limbs before screening; presented any injury (overuse or acute) at the time of testing; if they had any oncological, psychological and/or psychiatric illnesses; or if they did not attend on the day of the assessment.
Interventions
BEHAVIORALObservation
Ankle joint dorsiflexion was evaluated with the Weight-bearing lunge test through the Leg Motion system (LegMotion, your MOtion®, Albacete, Spain). Subjects were instructed to try to bring the knee to touch the metal rod (initially placed at a distance of 10 cm) without lifting the heel off the ground. The distance achieved was recorded in centimeters. Single-leg squat test was analyzed through the Leg Motion system (LegMotion, your MOtion®, Albacete, Spain). It consists of performing a monopodial squat to test dynamic knee valgus. They were to perform a single-leg squat to 30° knee flexion. The knee was considered to be aligned if the patella was over the second toe.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ankle joint dorsiflexion | 1 year | he Weight-bearing Lunge Test measured with the Leg Motion® system (Check Your Motion, Albacete) was used. Ankle dorsiflexion was recorded in centimeters. |
| Dynamic lower extremity valgus | 1 year | The Single Leg Squat Test was used. The evaluator recorded a frontal and sagittal view with two filming devices. The knee was considered to be aligned if the patella was over the second toe. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Wingspan | 1 year | Centimeters |
| Body mass index | 1 year | Kg/m2 |
| Hypermobility | 1 year | Beighton's criteria (scores of \>7 points out of a total of 9 points were considered hypermobile) |
| Weight | 1 year | Kilograms |
| Age categories | 1 year | According to the age of the participant could compete in 4 categories: U12, U14, U16 or U17. |
