背景前十字韧带重建术(ACLR)后的高损伤率促使我们有必要更好地了解回归运动后挥之不去的运动缺陷。体育比赛包括各种类型的感觉、运动和认知挑战；然而，在ACLR之后，在这种情况下的姿势控制缺陷还没有被很好地理解。研究问题ACLR在存在感觉、运动和认知挑战的情况下，姿势控制在多大程度上发生了改变，以及姿势控制与患者报告的症状是否相关？方法14名ACLR患者(4m/10f，21.2m±2.4m，76.9m±119.1g，1.70m±0.14m)和14个匹配的健康对照组(4m/10f，21.2m±0.14m，75.4m±15.3g，1.70m±0.15m)参与了研究。受试者在四种条件下完成单腿平衡、ACLR肢体或配对侧，分别是：1)睁眼，2)闭眼，3)视觉-认知双重任务(即反向数字广度)，4)运动双重任务(即接球)。计算各平衡条件下的样本熵(SEN)来表征压力控制中心的规律性。参与者还完成了患者报告的结果，以表征自我报告的膝盖功能、症状和恐惧。用混合效应模型检验平衡状态之间SEN的差异，并检验SEN与患者报告的结果之间的关系。结果检测到显著的逐个条件分组交互作用(P=0.043)。虽然运动双重任务和闭眼平衡条件与两组最低的SEN有关，但只有视觉-认知双重任务条件在两组之间有显著差异，ACLR组的SEN较低[ΔSEN的95%可信区间：(0.03，0.35)]。古斯-运动评分越低，ACLR组的SEN就越低(ρ=0.81，P<；=0.001)。有意义的是，这些发现与ACLR患者使用比对照组更不自动的姿势控制方法是一致的，特别是当面临视觉认知挑战时。改变的神经肌肉控制在ACLR手术后持续良好，并与患者报告的结果有关。
BackgroundHigh injury rates following anterior cruciate ligament reconstruction (ACLR) motivate the need to better understand lingering movement deficiencies following return to sport. Athletic competition involves various types of sensory, motor, and cognitive challenges; however, postural control deficiencies during this spectrum of conditions are not well understood following ACLR.Research questionTo what extent is postural control altered following ACLR in the presence of sensory, motor, and cognitive challenges, and does postural control correlate with patient-reported symptoms?MethodsFourteen individuals following ACLR (4 m/10 f, 21.2 ± 2.4 yr, 76.9 ± 19.1 kg, 1.70 ± 0.14 m) and fourteen matched healthy controls (4 m/10 f, 21.2 ± 1.4 yr, 75.4 ± 15.3 kg, 1.70 ± 0.15 m) participated in the study. Participants completed single-leg balance, ACLR limb or matched side for controls, under four conditions: 1) eyes open, 2) eyes closed, 3) visual-cognitive dual task (i.e., reverse digit span), and 4) motor dual task (i.e., catching a ball). Sample entropy (SEn) was calculated for each balance condition to characterize regularity of center of pressure control. Participants also completed patient-reported outcomes to characterize self-reported knee function, symptoms, and fear. A mixed effects model tested for differences in SEn between balance conditions, and Spearman correlations tested for relationships between SEn and patient-reported outcomes.ResultsA significant Group-by-Condition interaction was detected (P= 0.043). While the motor dual task and eyes closed balance conditions were associated with the lowest SEn for both groups, only the visual-cognitive dual task condition demonstrated a significant difference between groups, with the ACLR group having lower SEn [95% confidence interval for ΔSEn: (0.03, 0.35)]. Lower KOOS-Sport scores were associated with decreased SEn for the ACLR group (ρ = 0.81,P< 0.001).SignificanceThese findings are consistent with ACLR individuals using a less automatic approach to postural control compared to controls, particularly when presented with a visual-cognitive challenge. Altered neuromuscular control persists well after ACLR surgery and can be related to patient-reported outcomes.
