Abstract：
Understanding the implications of decreased femoral torsion on gait and running in children and adolescents might help orthopedic surgeons optimize treatment decisions. To date, there is limited evidence regarding the kinematic gait deviations between children with decreased femoral torsion and typically developing children, as well as the implications of the same on the adaptation of walking to running. A three-dimensional gait analysis study was undertaken to compare gait deviations during running and walking among patients with decreased femoral torsion (n = 15) and typically developing children (n = 11). Linear mixed models were utilized to establish comparisons within and between the two groups and investigate the relationship between clinical examination, spatial parameters, and the difference in hip rotation between running and walking. Patients exhibited increased external hip rotation during walking in comparison to controls, accompanied by higher peaks for the same as well as for knee valgus and external foot progression angle. A similar kinematic gait pattern was observed during running, with significant differences noted in peak knee valgus. In terms of variations from running to walking, patients internally rotated their initially externally rotated hip by 4°, whereas controls maintained the same internal hip rotation. Patients and controls displayed comparable kinematic gait deviations during running compared to walking. The passive hip range of motion, torsions, and velocity did not notably influence the variation in mean hip rotation from running to walking. This study underlines the potential of 3D gait kinematics to elucidate the functional implications of decreased FT and, hence, may contribute to clinical decision making.
摘要：
了解股骨扭转减少对儿童和青少年步态和跑步的影响可能有助于骨科医生优化治疗决策。迄今为止,关于股骨扭转减少的儿童和典型发育儿童之间的运动学步态偏差的证据有限，以及这对步行适应跑步的影响。进行了三维步态分析研究，以比较股骨扭转减少（n=15）和典型发育儿童（n=11）的患者在跑步和行走过程中的步态偏差。线性混合模型用于建立两组内部和之间的比较，并研究临床检查之间的关系。空间参数，以及跑步和步行之间髋关节旋转的差异。与对照组相比，患者在行走过程中表现出外髋关节旋转增加，伴随着较高的峰值，以及膝盖外翻和外足发展角。在跑步过程中观察到类似的运动学步态模式，在峰值膝关节外翻中发现了显着差异。从跑步到走路的变化来看，患者内部旋转他们最初外部旋转的髋关节4°，而对照组保持相同的内髋旋转。与步行相比，患者和对照组在跑步过程中表现出相当的运动学步态偏差。被动的髋关节运动范围，扭转,和速度没有显着影响从跑步到步行的平均髋关节旋转的变化。这项研究强调了3D步态运动学的潜力，以阐明减少FT的功能含义，因此，可能有助于临床决策。
