[Purpose] The purpose of this study was to evaluate the changes in gait patterns and clinical outcomes of patients with chronic ankle instability (CAI) following treatment with a home-based non-invasive biomechanical device. [Subjects and Methods] Thirty-three patients with CAI were compared with 43 healthy controls. Patients underwent a spatiotemporal gait assessment before and three months following treatment. Clinical evaluation was recorded with SF-36 Health Survey and the Foot and Ankle Outcome Score (FAOS). [Results] Significant baseline differences were found between groups. Patients with CAI showed a statistically significant improvement in velocity, cadence, symptomatic limb step length and single limb support over time. Significant improvements in SF-36 PCS and FAOS outcome scores were found in patients with CAI. [Conclusion] Patients with CAI have baseline spatiotemporal gait abnormalities as compared with healthy controls. However, clinical and gait metrics improvement can be expected after 12 weeks of perturbation training using a non-invasive biomechanical device.
[目的] 本研究旨在评估采用家庭式非侵入性生物力学设备治疗慢性踝关节不稳（CAI）患者后其步态模式和临床结局的变化。[对象与方法] 将33例CAI患者与43例健康对照者进行比较。患者在治疗前及治疗后3个月接受时空步态评估。采用SF-36健康调查和足踝结局评分（FAOS）进行临床评估。[结果] 两组间存在显著的基线差异。CAI患者的速度、步频、患侧步长和单腿支撑时间随时间推移有统计学意义的改善。CAI患者的SF-36生理健康评分（PCS）和FAOS结局评分有显著改善。[结论] 与健康对照者相比，CAI患者存在基线时空步态异常。然而，使用非侵入性生物力学设备进行12周的扰动训练后，临床和步态指标有望得到改善。
