To evaluate the literature regarding unilateral landing biomechanics and dynamic postural stability in individuals with and without chronic ankle instability (CAI).
Four online databases (PubMed, ScienceDirect, Scopus, and SportDiscus) were searched from the earliest records to 31 January 2018, as well as reference sections of related journal articles, to complete the systematic search. Studies investigating the influence of CAI on unilateral landing biomechanics and dynamic postural stability were systematically reviewed and evaluated.
Twenty articles met the criteria and were included in the systematic review. Individuals with CAI were found to have deficits in dynamic postural stability on the affected limb with medium to large effect sizes and altered lower extremity kinematics, most notably in the ankle and knee, with medium to large effect sizes. Additionally, greater loading rates and peak ground reaction forces, in addition to reductions in ankle muscle activity were also found in individuals with CAI during unilateral jump-landing tasks.
Individuals with CAI demonstrate dynamic postural stability deficits, lower extremity kinematic alterations, and reduced neuromuscular control during unilateral jump-landings. These are likely factors that contribute recurrent lateral ankle sprain injuries during dynamic activity in individuals with CAI.
评估有关慢性踝关节不稳（CAI）患者和无 CAI 患者单侧着陆生物力学和动态姿势稳定性的文献。
从最早的记录到 2018 年 1 月 31 日，我们在四个在线数据库（PubMed、ScienceDirect、Scopus 和 SportDiscus）中进行了系统搜索，并检索了相关期刊文章的参考文献部分，以完成系统搜索。对研究 CAI 对单侧着陆生物力学和动态姿势稳定性影响的研究进行了系统回顾和评估。
符合标准并纳入系统评价的有 20 篇文章。患有 CAI 的个体在受影响的肢体上表现出动态姿势稳定性缺陷，其效应量为中到大，下肢运动学也发生改变，尤其是踝关节和膝关节，其效应量为中到大。此外，在单侧跳跃着陆任务中，CAI 患者的加载率和峰值地面反作用力更大，而踝关节肌肉活动减少。
CAI 患者在单侧跳跃着陆时表现出动态姿势稳定性缺陷、下肢运动学改变和神经肌肉控制能力降低。这些可能是 CAI 患者在动态活动中反复发生外侧踝关节扭伤的原因。
