Abstract

Background: Lateral ankle sprain (LAS) is prevalent among runners, with many developing chronic ankle instability (CAI). While CAI is associated with many motor-behavioral, sensory-perceptual, and pathomechanical factors, its impact on gait biomechanics remains unclear. This cross-sectional study aimed to assess gait biomechanics and other factors contributing to CAI in runners.

Methods: Seventy participants (47 men and 23 women) were categorized as healthy (n = 24), acute LAS (n = 17), CAI (n = 16) and copers (n = 13). Walking and running spatiotemporal, kinetic and kinematic parameters were collected on an instrumented treadmill. Rehabilitation-oriented assessment outcomes were also assessed. One-way ANOVA or Kruskal-Wallis tests were used, along with their corresponding post-hoc tests. Effect sizes (g or r according to normality) were reported.

Results: Runners with CAI and acute LAS reported significantly greater perceived instability (r = 0.68-0.86) and worse self-reported function (r = 0.47-0.67) than healthy controls and copers. However, running biomechanics did not differ between groups, suggesting that traditional biomechanical assessments at comfortable speeds may not be sensitive to functional deficits in CAI. A notable finding was the lower mechanical work recovery during walking in copers compared to healthy controls (g = 0.98).

Conclusion: These results highlight the importance of considering self-reported function and perceived instability when assessing LAS and CAI. The absence of gross running gait alterations suggests that rehabilitation could safely integrate running early in recovery. However, more demanding tasks or advanced biomechanical modeling techniques may be needed to identify residual gait impairments.

踝关节扭伤史和临床结果对跑步者行走和跑步生物力学的影响有限:一项横断面研究。
背景:外侧踝关节扭伤(LAS)在跑步者中很普遍,许多人发展为慢性踝关节不稳定(CAI)。虽然CAI与许多运动-行为、感觉-知觉和病理力学因素有关,但其对步态生物力学的影响尚不清楚。这项横断面研究旨在评估步态生物力学和其他因素对跑步者CAI的影响。方法:70例受试者(男性47例,女性23例)分为健康(n = 24)、急性LAS (n = 17)、CAI (n = 16)和copd (n = 13)。在仪器化的跑步机上采集行走和跑步的时空、动力学和运动学参数。以康复为导向的评估结果也进行了评估。采用单因素方差分析或Kruskal-Wallis检验及其相应的事后检验。报告效应量(g或r,根据正态性)。结果:与健康对照组和跑步者相比,CAI和急性LAS的跑步者报告的感觉不稳定(r = 0.68-0.86)和自我报告的功能(r = 0.47-0.67)明显更差。然而,各组之间的跑步生物力学没有差异,这表明在舒适速度下的传统生物力学评估可能对CAI的功能缺陷不敏感。一个值得注意的发现是,与健康对照组相比,受试者在行走时的机械工作恢复较低(g = 0.98)。结论:这些结果强调了在评估LAS和CAI时考虑自我报告功能和感知不稳定性的重要性。没有明显的跑步步态改变表明康复可以安全地在康复早期整合跑步。然而,可能需要更苛刻的任务或先进的生物力学建模技术来识别残留的步态障碍。
