Improving jump-landing technique during rehabilitation is important and may be achieved through different feedback techniques, i.e., internal focus of attention (IF) or external focus of attention using a target (EF). However, there is a lack of evidence on the most effective feedback technique after anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to investigate the potential difference in jump-landing techniques between IF and EF instructions in patients after ACLR.
Thirty patients (12 females, mean age 23.26 ± 4.91 years) participated after ACLR. Patients were randomly assigned into two groups that each followed a different testing sequence. Patients performed a drop vertical jump-landing test after receiving instructions with varying types of focus of attention. The Landing Error Scoring System (LESS) assessed the jump-landing technique.
EF was associated with a significantly better LESS score (P < 0.001) compared with IF. Only EF instructions led to improvements in jump-landing technique.
Using a target as EF resulted in a significantly better jump-landing technique than IF in patients after ACLR. This indicates that increased use of EF could or might result in a better treatment outcome during ACLR rehabilitation.
在康复过程中改善跳跃着陆技术很重要，可以通过不同的反馈技术来实现，即内部注意力集中（IF）或使用目标的外部注意力集中（EF）。然而，在前交叉韧带重建（ACLR）后，哪种反馈技术最有效还缺乏证据。本研究旨在探讨 ACLR 后患者在 IF 和 EF 指导下跳跃着陆技术的潜在差异。
30 名患者（12 名女性，平均年龄 23.26±4.91 岁）参与了 ACLR 后研究。患者随机分为两组，每组采用不同的测试顺序。患者在接受不同注意力集中类型的指导后进行垂直跳落地测试。着陆错误评分系统（LESS）评估跳跃着陆技术。
与 IF 相比，EF 与显著更好的 LESS 评分相关（P<0.001）。只有 EF 指导才能改善跳跃着陆技术。
在 ACLR 后患者中，使用目标作为 EF 比 IF 产生了明显更好的跳跃着陆技术。这表明在 ACLR 康复过程中增加 EF 的使用可能会或可能会导致更好的治疗效果。
