To determine the intra- and inter-session reliability of balance and cognitive performance in anterior cruciate ligament-deficient (ACLD) and ACL-reconstructed (ACLR) and matched athletes.
Using SMART EquiTest, recovery reactions of the groups were assessed during single-leg standing, following medium and large forward perturbations with and without performing a cognitive (Stroop) task. The outcomes included reaction time (RT), latency and amplitude for balance and error ratio (ER) and RT for cognitive performance. The participants of each group repeated the tests 2-7 days after the first session. Intraclass correlation coefficient (ICC) and standard error of measurement were computed in order to assess relative and absolute reliability, respectively.
Single- and dual-task balance measures had moderate to very high reliability in ACLD (ICC = 0.63-0.88), ACLR (ICC = 0.62-0.93) and control (ICC = 0.69-0.98) athletes. The ICCs for RT of Stroop were between 0.87 and 0.90 in ACLD, between 0.70 and 0.74 in ACLR and between 0.66 and 0.70 in controls and for ER of Stroop were between 0.36 and 0.90 in ACLD, between 0.42 and 0.49 in ACLR and between 0.41 and 0.51 in controls.
Balance measures and RT of the cognitive task in single- and dual-task conditions have acceptable reliability and may be incorporated into the evaluation of physical and mental function of athletes following ACL injury and reconstruction. ER of the cognitive task is less reliable which needs to be considered in future research.

确定前交叉韧带缺失（ACL 缺失）和前交叉韧带重建（ACL 重建）以及匹配运动员的平衡和认知表现的内和间测试可靠性。
使用 SMART EquiTest，在单腿站立时评估组的恢复反应，在前向中等和大的扰动下，在执行认知（Stroop）任务和不执行认知任务时，评估平衡和认知表现的反应时间（RT）、潜伏期和幅度以及错误比（ER）和 RT。每组参与者在第一次测试后 2-7 天重复测试。计算了组内相关系数（ICC）和测量标准误差，以分别评估相对和绝对可靠性。
ACL 缺失（ICC = 0.63-0.88）、ACL 重建（ICC = 0.62-0.93）和对照组（ICC = 0.69-0.98）运动员的单任务和双任务平衡测量具有中等到非常高的可靠性。Stroop 的 RT 的 ICC 在 ACLD 中为 0.87 至 0.90，在 ACLR 中为 0.70 至 0.74，在对照组中为 0.66 至 0.70，Stroop 的 ER 的 ICC 在 ACLD 中为 0.36 至 0.90，在 ACLR 中为 0.42 至 0.49，在对照组中为 0.41 至 0.51。
平衡测量和认知任务的 RT 在单任务和双任务条件下具有可接受的可靠性，可能被纳入 ACL 损伤和重建后运动员身体和心理健康功能的评估中。认知任务的 ER 可靠性较低，这需要在未来的研究中考虑。
