与男性相比，女性脚踝/足部区域受伤的比例更高。然而，足部损伤与性别相关的差异的原因仍不清楚。最近，关节协调性和协调性变异性被认为是定义损伤状态和潜在损伤风险的关键指标。本研究的目的是调查跑步过程中足关节协调性和变异性方面与性别相关的差异。十二名健康男性和十二名健康女性在跑步机上跑步。采用改进的矢量编码技术来识别涉及小腿、后足、中足和前足节段的足关节之间的协调性和变异性，并将其分为以下四种协调模式：与近端优势同相、与远端优势同相、与近端优势反相和与远端优势反相。男性和女性之间的所有时空参数和足部着地角度没有差异。男性和女性跑步时足部关节变异性的协调性相似，但女性的前足后足-小腿与中足-后足配对（男性7.2%，女性13.9%）以及中足-后足与前足-中足配对（男性18.6%，女性39.8%）的近端优势反相比例显着高于男性。另外，男女跑步时足部关节的协调性存在差异，且这些参数的影响大小均较大。研究结果可能有助于理解导致男性和女性受伤风险差异的潜在机制，并且可能提供有关足部关节协调性和变异性的新数据，可用作生物力学和临床跑步研究的参考数据。本文的在线版本 (10.1186/s13047-018-0295-9) 包含补充材料，可供授权用户使用。
Women, as compared with men, have a higher proportion of injuries in the ankle/foot region. However, the reason for this sex-related difference in foot injuries remains unclear. Recently, joint coordination and variability of coordination have been suggested to be a critical index for defining both the state of injury and the potential risk of injury. The purpose of this study was to investigate sex-related differences in coordination and variability among the foot joints during running. Twelve healthy men and 12 healthy women ran on a treadmill. A modified vector coding technique was used to identify coordination and variability among foot joints involving the shank, rearfoot, midfoot, and forefoot segments, and categorized into the following four coordination patterns: in-phase with proximal dominancy, in-phase with distal dominancy, anti-phase with proximal dominancy, and anti-phase with distal dominancy. There were no differences in all spatiotemporal parameters and in the foot strike angle between men and women. Coordination of variability of the foot joints during running was similar between men and women, but the anti-phase with proximal dominancy in proportion of frontal rearfoot-shank vs. midfoot-rearfoot couple (men; 7.2%, women; 13.9%) and midfoot-rearfoot vs. forefoot-midfoot couple (men; 18.6%, women; 39.8%) in women was significantly increased compared to that in men. Other all coordination of the foot joints during running differed between men and women, and effect sizes of these parameters were all large. The results may be useful for understanding the underlying mechanism contributing to differences in injury risk in men and women, and may provide novel data on foot joint coordination and variability that could be used as reference data for both biomechanical and clinical running studies.
