Background

Athletes exhibit deficits in knee proprioception following anterior cruciate ligament reconstruction. Neuromuscular training programs improve knee proprioception in uninjured athletes; however, the effects on knee proprioception in athletes who have undergone anterior cruciate ligament reconstruction is not well understood. The purpose of this study was to examine the effects of a neuromuscular training program on knee proprioception in athletes who have returned to sport following anterior cruciate ligament reconstruction.

Methods

Twenty-four male athletes, who had undergone anterior cruciate ligament reconstruction within the previous 6–12 months and returned to sport, participated in this randomized controlled trial. Athletes were randomly allocated to an experimental group (n = 12) that took part in an 8-week neuromuscular training program or a control group (n = 12) that simply continued their typical training routine. Knee position sense was assessed at baseline and after the 8-week period (post-testing). One-way analysis of covariance, with baseline performance included as a covariate, was used to compare knee position sense errors for the reconstructed limbs of the experimental and control groups at the post-testing time point.

Findings

Knee position sense errors decreased by 51.7% for the experimental group and only 4.4% for the control group over the 8-week period. As a result, the experimental group demonstrated lower knee position sense errors, compared to the control group, at the post-testing time point (P < .001).

Interpretation

Athletes with a history of anterior cruciate ligament reconstruction may benefit from participation in a neuromuscular training program, even after completing post-operative rehabilitation.

有前交叉韧带重建史的神经肌肉训练可改善运动员的膝盖本体感受：一项随机对照试验。

背景

运动员在前十字韧带重建后表现出膝关节本体感觉缺陷。神经肌肉训练计划可改善未受伤运动员的膝盖本体感受；然而，对于前交叉韧带重建运动员对膝盖本体感受的影响尚不清楚。这项研究的目的是检查神经肌肉训练计划对前交叉韧带重建后恢复运动的运动员膝盖本体感受的影响。

方法

在此之前的随机对照试验中，有24位男性运动员在前6到12个月内接受了前十字韧带重建并重新参加运动。运动员被随机分配到 参加8周神经肌肉训练计划的实验组（n = 12）或单纯继续常规训练的对照组（n = 12）。在基线和8周后（测试后）评估膝关节位置感。对协方差的单向分析（包括基线性能作为协变量）用于比较实验组和对照组在测试后时间点的重建肢体的膝盖位置感知误差。

发现

在8周的时间内，实验组的膝盖位置感知错误减少了51.7％，而对照组仅减少了4.4％。结果，与对照组相比，实验组在测试后的时间点显示出较低的膝盖位置感测误差（P  <.001）。

解释

具有前十字韧带重建史的运动员即使完成了术后康复，也可以从参加神经肌肉训练计划中受益。
