Postural control deficits and persistent joint stability issues are prevalent in population with anterior cruciate ligament (ACL) injuries or reconstructions. Postural control is typically assessed using the center of pressure (CoP) parameters during the static single-leg stance with a force plate. However, previous studies have reported unclear definitions and descriptions of the CoP parameters, causing inconsistent results of postural control deficits in a specific population.
To 1) summarize CoP parameters commonly used to evaluate postural control deficits in ACL injured or reconstructed population, and 2) identify the differences in CoP parameters with opened and closed eyes during the single-leg stance between ACL injured or reconstructed and control groups.
PubMed, Embase, Cochrane Library, CINAHL, Scopus, Web of Science, and SPORTDiscus databases were searched up to July 2023. Data were obtained from the selected articles and underwent quality and risk of bias assessment and meta-analysis using random-effect models. Subgroup analysis within ACL injured or reconstructed group were also performed.
A total of 14 articles were included in the analysis after screening. The injured knee of the ACL injured or reconstructed group differed insignificantly in sway amplitude, sway area, and sway velocity during static single-leg stance under opened and closed eyes when compared with the control group. In the subgroup analysis, we found that there was only significant difference in sway velocity with open eyes ( = 0.47, = 0.001) between ACL reconstructed group and control group.
This study summarized the common CoP parameters used to evaluate postural control in ACL injured or reconstructed population. The results only showed weak difference in sway velocity between ACL reconstructed population and healthy individuals with opened eyes during the static single-leg stance.
姿势控制缺陷和持续的关节稳定性问题在患有前交叉韧带（ACL）损伤或重建的人群中普遍存在。姿势控制通常在静态单腿站立时使用测力台通过压力中心（CoP）参数进行评估。然而，先前的研究报告称，CoP参数的定义和描述不明确，导致特定人群中姿势控制缺陷的结果不一致。
1）总结常用于评估ACL损伤或重建人群姿势控制缺陷的CoP参数，2）确定ACL损伤或重建组与对照组在单腿站立时睁眼和闭眼情况下CoP参数的差异。
检索了截至2023年7月的PubMed、Embase、Cochrane图书馆、CINAHL、Scopus、Web of Science和SPORTDiscus数据库。从选定的文章中获取数据，并使用随机效应模型进行质量和偏倚风险评估以及荟萃分析。还对ACL损伤或重建组进行了亚组分析。
筛选后共纳入14篇文章进行分析。与对照组相比，ACL损伤或重建组在睁眼和闭眼静态单腿站立时，患侧膝关节在摆动幅度、摆动面积和摆动速度方面无显著差异。在亚组分析中，我们发现ACL重建组与对照组之间仅在睁眼时的摆动速度上存在显著差异（ = 0.47， = 0.001）。
本研究总结了用于评估ACL损伤或重建人群姿势控制的常见CoP参数。结果仅显示，在静态单腿站立时，ACL重建人群与健康个体睁眼时在摆动速度上存在微弱差异。
