分离与膝内收肌力矩变异性相关的特定关节/肢体节段可能提供临床上重要的数据，有助于确定减少内侧胫股关节蟾蜍的策略。本研究的目的是检验人类运动过程中足部和大腿的旋转是否是膝内收肌力矩变异的重要决定因素。对 32 名膝盖放射学正常的健康成年女性（平均年龄 54 +/- 12 岁，平均 BMI 25 4 kg m(-2)）进行了三维步态分析。在步态周期的早期和后期站立阶段，检查足部旋转、大腿旋转和膝外收力矩之间的关系。足部旋转程度与站立后期峰值膝内收力矩的大小显着相关（r = 0.40，p = 0.024）。大腿旋转和膝内收峰值力矩之间没有明显的关联。本研究中脚旋转和膝内收力矩之间的关联表明，脚外旋行走的女性在站立后期会减少膝内收力矩。这一结果意味着足部运动学的变化可以改变内侧。步态中的胫股蟾蜍，这对于预防和治疗膝骨关节炎可能很重要。 (c) 2006 年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Isolating the particular joints/limb segments associated with knee adductor moment variability may provide clinically important data that could help to identify strategies to reduce medial tibiofemoralt joint toad. The aim of this study was to examine whether or not foot and thigh rotation during human locomotion are significant determinants of knee adductor moment variability.Three-dimensional gait analyses were performed on 32 healthy adult women (mean age 54 +/- 12 years, mean BMI 25 4 kg m(-2)) with radiologically normal knees. The relationships between foot rotation, thigh rotation and the external knee adduction moment were examined during early and late-stance phases of the gait cycle.The degree of foot rotation correlated significantly with the magnitude of the peak knee adduction moment during late stance (r = 0.40, p = 0.024). No significant associations were apparent between thigh rotation and the peak knee adduction moment.The association between foot rotation and the knee adduction moment in this study suggests that women who walk with external rotation at the foot reduce their knee adduction moment during late stance. This result implies that changes in foot kinematics can modify the medial. tibiofemoral toad during gait, which may be important in the prevention and management of knee osteoarthritis.
