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.

Conditions

Knee Injuries; Ankle Injuries and Disorders; Movement, Abnormal; Adolescent Development

Keywords

Basketball; Adolescent; Knee valgus; Range of motion; Ankle

Outcome Measures

Primary Outcomes (2)

• Ankle joint dorsiflexion

  he Weight-bearing Lunge Test measured with the Leg Motion® system (Check Your Motion, Albacete) was used. Ankle dorsiflexion was recorded in centimeters.

  1 year

• Dynamic lower extremity valgus

  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.

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)

Behavioral: Observation

Interventions

Observation 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.

Experimental group

Eligibility Criteria

• Age: 12 Years - 17 Years
• Sex: all
