背景对于那些有慢性踝关节不稳定（CAI）并且在最初的外侧踝关节扭伤（LAS）后12个月内没有复发或不稳定（copers）的个体，关于不同病因的原因的信息有限。评估的运动模式的copers和个人与CAI和LAS复发是必不可少的机械因素，影响patient outcomes.Research QuestionDoes协调和协调的变化后足，中足，前足提出了一个潜在的致病模式CAI或coper？方法采用横断面研究方法，将35名男性患者分为CAI组（n = 13）、Coper组（n = 12）和对照组（n = 10）。 参与者在跑步机上以3.5 m/s的固定速度进行后足撞击跑步。后足，中足，前足之间的耦合角，代表节间协调，计算使用修改后的矢量编码技术，并分为四个协调模式。耦合角的标准偏差代表协调变异在立场phase.ResultsOne对照参与者和CAI参与者被排除在外，并进行最终分析的CAI（n = 12），coper（n = 12），和控制（n = 9）组。在站立后期，与CAI组相比，Coper组显示出远侧优势的同相比例显著更大（p = 0.02，效应量=0.17），近侧优势的同相比例显著更低（p = 0.05，效应量=0.17）。在早期站立期间，coper组显示出远侧优势的反相比例显著低于CAI组（p = 0.03，效应量=0.18）。有没有组之间的差异，在脚内的变化。SignificanceThe内脚协调观察铜组表明，这种运动模式可能会降低踝关节扭伤的风险。
BackgroundThere is limited information regarding the cause for the different etiologies in individuals with initial lateral ankle sprains (LAS) who have chronic ankle instability (CAI) and no recurrence or instability for > 12 months (copers) following initial LAS. Assessing the movement patterns of copers and individuals with CAI and LAS recurrence is essential for identifying the mechanical factors that affect patient outcomes.Research questionDoes coordination and coordination variability of rearfoot, midfoot, and forefoot present a potentially causative pattern for CAI or coper?MethodsThis cross-sectional study included 35 males who were divided into the CAI (n = 13), coper (n = 12), and control group (n = 10). Participants performed rearfoot strike running on the treadmill at a fixed speed of 3.5 m/s. The coupling angle between the rearfoot, midfoot, and forefoot, representing intersegmental coordination, was calculated using the modified vector coding technique and categorized into four coordination patterns. The coupling angle standard deviation served represented coordination variability during the stance phase.ResultsOne control participant and one CAI participant were excluded, and final analyses were performed on the CAI (n = 12), coper (n = 12), and control (n = 9) groups. During late stance, the coper group showed a significantly greater proportion of in-phase with distal dominancy (p = 0.02, effect size=0.17) and a significantly lower proportion of in-phase with proximal dominancy (p = 0.05, effect size=0.17), than the CAI group. During the early stance, the coper group showed a significantly lower proportion of anti-phase with distal dominancy than the CAI group (p = 0.03, effect size=0.18). There were no differences in intra-foot variability among the groups.SignificanceThe intra-foot coordination observed in the coper group suggests that this movement pattern may reduce the risk of ankle sprains.
