Abstract

Background

Restoring pre-injury normal gait following Anterior Cruciate Ligament Reconstruction (ACLR) is a critical challenge. The purpose of this study was to compare spatiotemporal parameters in athletes following ACL reconstruction with healthy athletes when cognitive load and speed were manipulated.

Methods

Twenty male soccer players with an ACLR history and 20 healthy matched individuals completed walking tasks under four conditions: with and without a cognitive load (auditory Stroop task), and at preferred speed as well as high speed (20% higher than the individual’s preferred speed). Step Width (SW), Step Time (ST), Step Length (SL), as well as Symmetry Indexes (SIs) were measured using three-dimensional (3D) motion analysis. Gait symmetry was evaluated by SIs. The data was analyzed using Three-way analysis of variances with repeated measures (ANOVA 3 × 2).

Results

ST was significantly different between groups (P = 0.04) when the cognitive load was applied at the preferred speed. However, other spatiotemporal parameters were not significantly different between groups in any conditions (p > 0.05). The SW was reduced during high–speed walking with cognitive load in both groups (p = 0.004). High-speed resulted in greater SL (p < 0.001) and lower ST (p < 0.001) in both groups. SI was not significantly different for any parameter between groups under any conditions, however, the interaction of cognitive task × speed was significant for SW (p = 0.03).

Conclusion

Athletes at a mean of 19 months following ACL Reconstruction appear to manage speed and cognitive challenges similar to age and activity matched individuals who have not had surgery.

认知任务和步态速度对前交叉韧带重建运动员步态时空参数影响的横断面研究。

背景：在前交叉韧带重建（ACLR）后恢复损伤前的正常步态是一个关键的挑战。本研究的目的是比较前交叉韧带重建后运动员与健康运动员在认知负荷和速度被操纵时的时空参数。方法：20名有ACLR病史的男性足球运动员和20名健康匹配者在有认知负荷和无认知负荷（听觉Stroop任务）、首选速度和高速（比个人首选速度高20%）4种条件下完成步行任务。采用三维（3D）运动分析方法测量步宽（SW）、步长（ST）、步长（SL）和对称指数（si）。采用SIs评价步态对称性。采用重复测量的三向方差分析（ANOVA 3 × 2）对数据进行分析。结果：以首选速度施加认知负荷时，组间ST差异显著（P = 0.04）。其他时空参数在各条件下各组间无显著差异（p < 0.05）。两组在有认知负荷的情况下，高速步行时SW均降低（p = 0.004）。结论：前交叉韧带重建后平均19个月的运动员处理速度和认知挑战的能力与未接受手术的年龄和活动匹配的个体相似。
