Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental group

All participants allowed three practice trials for each test in this order: the Weight-bearing lunge test and the Single-leg squat test. Both of them were evaluated through the Leg Motion system (LegMotion, your MOtion®, Albacete, Spain)

Observation

Intervention Type BEHAVIORAL

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.
