BACKGROUND: Several biomechanical outcomes are being used to monitor the risk of injuries; therefore, their reliability and measurement errors need to be known. OBJECTIVE: To measure the reliability and measurement error in lower limb 3D gait analysis outcomes during a 90∘ and 135∘ change of direction (COD) manoeuvre. METHODS: A test re-test reliability study for ten healthy recreational players was conducted at seven-day intervals. Kinematics (Hip flexion, adduction, internal rotation angles and knee flexion abduction angles) and kinetics (Knee abduction moment and vertical ground reaction force) data during cutting 90∘ and 135∘ were collected using 3D gait analysis and force platform. Five trials for each task and leg were collected. Standard error of measurement (SEM) and the intraclass correlation coefficient (ICC) were calculated form the randomised leg. RESULT: The ICC values of the kinematics, kinetics, and vertical ground reaction force (VGRF) outcomes (90∘ and 135∘) ranged from 0.85 to 0.95, showing good to excellent reliability. The SEM for joint angles was less than 1.69∘. The VGRV showed a higher ICC value than the other outcomes. CONCLUSION: The current study results support the use of kinematics, kinetics, and VGRF outcomes for the assessment of knee ACL risk in clinic or research. However, the hip internal rotation angle should be treated with caution since the standard measurement error exceeded 10% compared to the mean value. The measurement errors provided in the current study are valuable for future studies.

休闲足球运动员在转向 90 度和 135 度动作期间下肢 3D 步态分析变量的可靠性

背景:一些生物力学结果被用来监测受伤的风险;因此,需要知道它们的可靠性和测量误差。目标:测量 90° 和 135° 变向 (COD) 动作期间下肢 3D 步态分析结果的可靠性和测量误差。方法:每隔 7 天对 10 名健康的休闲玩家进行重测可靠性研究。使用 3D 步态分析和力平台收集 90° 和 135° 切割期间的运动学(髋关节屈曲、内收、内旋角度和膝关节屈曲外展角度)和动力学(膝关节外展力矩和垂直地面反作用力)数据。收集了每项任务和每条腿的五个试验。测量的标准误差 (SEM) 和组内相关系数 (ICC) 由随机组计算。结果:运动学、动力学和垂直地面反作用力 (VGRF) 结果(90∘ 和 135∘)的 ICC 值介于 0.85 和 0.95 之间,显示出良好到极好的可靠性。关节角度的 SEM 小于 1.69∘。VGRV 显示出比其他结果更高的 ICC 值。结论:目前的研究结果支持在临床或研究中使用运动学、动力学和 VGRF 结果来评估膝关节 ACL 风险。然而,应谨慎对待髋关节内旋角,因为与平均值相比,标准测量误差超过 10%。当前研究中提供的测量误差对未来的研究很有价值。动力学和垂直地面反作用力 (VGRF) 结果(90∘ 和 135∘)在 0.85 到 0.95 之间,显示出良好到极好的可靠性。关节角度的 SEM 小于 1.69∘。VGRV 显示出比其他结果更高的 ICC 值。结论:目前的研究结果支持在临床或研究中使用运动学、动力学和 VGRF 结果来评估膝关节 ACL 风险。然而,应谨慎对待髋关节内旋角,因为与平均值相比,标准测量误差超过 10%。当前研究中提供的测量误差对未来的研究很有价值。动力学和垂直地面反作用力 (VGRF) 结果(90∘ 和 135∘)在 0.85 到 0.95 之间,显示出良好到极好的可靠性。关节角度的 SEM 小于 1.69∘。VGRV 显示出比其他结果更高的 ICC 值。结论:目前的研究结果支持在临床或研究中使用运动学、动力学和 VGRF 结果来评估膝关节 ACL 风险。然而,应谨慎对待髋关节内旋角,因为与平均值相比,标准测量误差超过 10%。当前研究中提供的测量误差对未来的研究很有价值。VGRV 显示出比其他结果更高的 ICC 值。结论:目前的研究结果支持在临床或研究中使用运动学、动力学和 VGRF 结果来评估膝关节 ACL 风险。然而,应谨慎对待髋关节内旋角,因为与平均值相比,标准测量误差超过 10%。当前研究中提供的测量误差对未来的研究很有价值。VGRV 显示出比其他结果更高的 ICC 值。结论:目前的研究结果支持在临床或研究中使用运动学、动力学和 VGRF 结果来评估膝关节 ACL 风险。然而,应谨慎对待髋关节内旋角,因为与平均值相比,标准测量误差超过 10%。当前研究中提供的测量误差对未来的研究很有价值。
