The primary aim of this study was to identify kinematic differences at initial contact between female futsal players with and without previous knee injury, using a functional motor pattern test. The secondary aim was to determine kinematic differences between the dominant and non-dominant limb in the whole group, using the same test. A cross-sectional study was performed in 16 female futsal players allocated into two groups: eight females with a previous knee injury, i.e., affected by the valgus collapse mechanism without surgical intervention, and eight with no previous injury. The evaluation protocol included the change-of-direction and acceleration test (CODAT). One registration was made for each lower limb, i.e., the dominant (the preferred kicking limb) and non-dominant limb. A 3D motion capture system (Qualisys AB, Göteborg, Sweden) was used to analyze the kinematics. The effect sizes between the groups demonstrated a strong effect size towards more physiological positions in the non-injured group in the following kinematics in the dominant limb: hip adduction ( = 0.82), hip internal rotation ( = 0.88), and ipsilateral pelvis rotation ( = 1.06). The -test for the dominant and non-dominant limb in the whole group showed the following differences in knee valgus: dominant limb (9.02 ± 7.31 degrees) and non-dominant limb (1.27 ± 9.05 degrees) ( = 0.049). Conclusions: The players with no previous history of knee injury had a more physiological position for avoiding the valgus collapse mechanism in the hip adduction and internal rotation, and in the pelvis rotation in the dominant limb. All the players showed more knee valgus in the dominant limb, which is the limb at greater risk of injury.
本研究的主要目的是通过功能性运动模式测试，确定既往有膝关节损伤和无膝关节损伤的女子五人制足球运动员在初始接触时的运动学差异。次要目的是使用相同测试确定整个组中优势腿和非优势腿之间的运动学差异。对16名女子五人制足球运动员进行了横断面研究，分为两组：8名既往有膝关节损伤，即受外翻塌陷机制影响但未接受手术干预的女性，以及8名无既往损伤的女性。评估方案包括变向和加速测试（CODAT）。对每个下肢进行一次记录，即优势腿（首选踢球腿）和非优势腿。使用三维运动捕捉系统（瑞典哥德堡的Qualisys AB公司）分析运动学。两组之间的效应量表明，在优势腿的以下运动学方面，非损伤组向更生理位置呈现出较强的效应量：髋关节内收（=0.82）、髋关节内旋（=0.88）和同侧骨盆旋转（=1.06）。对整个组中优势腿和非优势腿的t检验显示膝关节外翻存在以下差异：优势腿（9.02±7.31度）和非优势腿（1.27±9.05度）（p=0.049）。结论：既往无膝关节损伤史的运动员在髋关节内收、内旋以及优势腿骨盆旋转方面具有更生理的位置，以避免外翻塌陷机制。所有运动员的优势腿均表现出更多的膝关节外翻，而优势腿是受伤风险更高的肢体。
