The Association Between Restricted Ankle Joint Dorsiflexion and Dynamic Knee Valgus

"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."
