背景：前交叉韧带断裂是活跃个体最常见的膝关节韧带损伤，相对损伤风险具有性别特异性。女性不仅表现出受伤的风险增加，而且韧带断裂后的反应也较差。扰动训练在健康女性中显示出积极的效果，但尚未评估受伤后对训练的性别特异性反应。本调查的目的是描述扰动训练对男性和女性非应对者步态特征的影响。方法：使用标准运动分析技术，收集 12 名男性和 9 名女性非应对者训练前后的生物力学数据。受试者以一致的、自行选择的速度在嵌入式测力板上行走。使用方差和最小临床重要差异的混合模型分析对双肢的数据进行后处理和分析，以比较男性和女性的肢体行为。 结果：在训练之前，只有女性表现出明显的髋关节偏移不对称性（ES = 1.03；P = 0.009）。最小的临床重要差异值表明，与她们自己的未受累肢体和男性非受累肢体相比，女性受累肢体的髋关节和膝关节屈曲角度和力矩减小，膝关节偏移缩短，髋关节偏移增加。训练后，只有膝关节伸肌力矩值超过了女性的最小临床重要差异。解释：女性非训练者在受伤和扰动训练后表现出独特的运动策略。女性可能是非应对者中一个有意义的亚群，未来的调查应考虑性别对非应对者结果的影响。 (C) 2011 Elsevier Ltd. 保留所有权利。
Background: Anterior cruciate ligament rupture is the most common knee ligament injury sustained by active individuals, and the relative injury risk is sex-specific. Women not only demonstrate an increased risk for injury, but also a poorer response following ligament rupture. Perturbation training has shown positive results in healthy females, but gender-specific responses to training after injury have not been evaluated. The purpose of this investigation was to describe the effects of perturbation training on the gait characteristics of male and female non-copers.Methods: Biomechanical data were collected before and after training on 12 male and nine female non-copers using standard motion analysis techniques. Subjects walked at a consistent, self-selected speed over an embedded force plate. Data from both limbs were post-processed and analyzed using a mixed model analysis of variance and minimal clinically important differences to compare the limb behaviors of men and women.Findings: Prior to training, only women demonstrated significant hip joint excursion asymmetry (ES = 1.03; P = 0.009). Minimal clinically important difference values showed that the involved limb of the women had reduced hip and knee flexion angles and moments, truncated knee excursions, and increased hip excursions when compared to their own uninvolved limb and the limbs of the male non-copers. Following training, only knee extensor moment values exceeded the minimal clinically important differences in women.Interpretation: Female non-copers demonstrated unique movement strategies following injury and perturbation training. Women may be a meaningful subgroup of non-copers, and future investigations should consider the effects of gender in the outcomes of non-copers. (C) 2011 Elsevier Ltd. All rights reserved.
