此前，视觉认知能力与健康运动员的前十字韧带损伤和损伤风险生物力学有关。神经影像学报告发现，前十字韧带重建（ACLR）后个体中与视觉空间处理、感觉统合和视觉认知相对应的区域的神经活动增加，表明运动控制的潜在神经补偿策略。然而，目前尚不清楚 ACLR 后视觉认知、神经活动和神经肌肉能力指标之间是否存在关系。本研究的目的是（1）评估视觉认知功能与神经肌肉控制测量（本体感觉和稳定时间 [TTS]）、等速强度和主观功能之间的关系，以及（2）检查 ACLR（n = 16；自手术后时间 41.4 +/- 33.0 个月）和人口统计学相似的对照（n = 15）之间视觉认知的神经相关性。视觉认知通过 ImPACT 视觉运动和视觉记忆分量表进行评估。比较组间目标膝角 20 度的本体感觉、着陆 TTS、力量和主观功能的结果变量，并在组内关联视觉认知，以确定视觉认知与手术时间控制的结果变量之间的关系（ACLR 组）。对照组具有更好的 IKDC 分数和强度。在 ACLR 组中，视觉记忆和视觉运动能力分别与本体感觉错误 (r = -0.63) 和 TTS (r = -0.61) 呈负相关，而对照组则不然。在 ACLR 组中，视觉认知与楔前叶和后扣带皮层的神经活动增加有关，但与对照组参与者无关。这些数据表明，ACLR 参与者维持本体感觉和稳定性的神经策略各不相同，并且可能取决于视觉认知和感觉统合神经活动。
Visual cognitive ability has previously been associated with anterior cruciate ligament injury and injury risk biomechanics in healthy athletes. Neuroimaging reports have identified increased neural activity in regions corresponding to visual-spatial processing, sensory integration, and visual cognition in individuals after anterior cruciate ligament reconstruction (ACLR), indicating potential neural compensatory strategies for motor control. However, it remains unclear whether there is a relationship between visual cognition, neural activity, and metrics of neuromuscular ability after ACLR. The purpose of this study was to (1) evaluate the relationship between visual cognitive function and measurements of neuromuscular control (proprioception and time to stability [TTS]), isokinetic strength, and subjective function, and (2) examine the neural correlates of visual cognition between ACLR (n = 16; time since surgery 41.4 +/- 33.0 months) and demographically similar controls (n = 15). Visual cognition was assessed by the ImPACT visual motor and visual memory subscales. Outcome variables of proprioception to target knee angle 20 degrees, landing TTS, strength, and subjective function were compared between groups, and visual cognition was correlated within groups to determine the relationship between visual cognition and outcome variables controlled for time from surgery (ACLR group). The control group had better IKDC scores and strength. Visual memory and visual motor ability were negatively associated with proprioception error (r = -0.63) and TTS (r = -0.61), respectively, in the ACLR group but not controls. Visual cognition was associated with increased neural activity in the precuneus and posterior cingulate cortex in the ACLR group but not control participants. These data suggest the neural strategy in which ACLR participants maintain proprioception and stability varies, and may depend on visual cognition and sensory integration neural activity.
