摘要

目的分析具有前交叉韧带重建（ACLr）史的娱乐性运动女性在单任务和双任务条件下，即时视觉和语言反馈是否对着陆力学产生影响。设计横断面队列研究。SettingMotion实验室。参与者包括33名大学年龄的女性，她们在aclr后的状态为2到5年，以及33名匹配的健康对照组。材料和方法30在单次试验中进行降落，试验后立即反馈，然后进行vGRF峰值和对称性的保留试验。主要结果测量：从50厘米平台降落时的垂直地面反作用力（vGRFs）和与体重归一化的装载率（LR）。结果vGRF峰值存在基线、测试后和转移任务试验的时间效应。基于基线、测试后和转移任务，ACLr和健康组之间存在显著的组-时间交互作用。对于峰值vGRF不对称，基线、测试后和转移任务试验没有时间效应。vGRF峰不对称存在显著的组效应。从基线、测试后和转移任务开始，总LR没有显示时间效应。与健康组相比，ACLr组表现出更高的LR。结果表明，加入增强反馈后，下降降落过程中vGRF峰值降低，vGRF不对称性降低。ACLr组的LR高于对照组。康复专家可能能够将有针对性的反馈作为干预措施，以帮助解决ACLr后的着陆不对称。

Effects of augmented feedback on landing mechanics after anterior cruciate ligament reconstruction in collegiate females compared to healthy controls

Objective

To analyze if immediate visual and verbal feedback influenced landing mechanics during single and dual-task conditions in recreationally active females with a history of anterior cruciate ligament reconstruction (ACLr) compared to healthy controls.

Design

Cross-sectional cohort study.

Setting

Motion Laboratory.

Participants

33 college-aged females with two to five years status post-ACLr and 33 matched health controls.

Materials and methods

30 Drop landings were performed over one single session with immediate post-trial feedback followed by a retention trial on peak vGRF and symmetry.

Main outcome measures

Vertical ground reaction forces (vGRFs) during drop landing from a 50-cm platform and loading rate (LR) normalized to body weight.

Results

For peak vGRF, there was a time effect from baseline, post-test, and transfer task trials. Based on baseline, post-test, and transfer tasks, there was a significant group-by-time interaction between the ACLr and a healthy group. For peak vGRF asymmetry, there was no time effect from baseline, post-test, and transfer task trials. There was a significant group effect for peak vGRF asymmetry. Total LR did not show a time effect from baseline, post-test, and transfer task. The ACLr group demonstrated higher LR compared to the health group.

Conclusions

Results demonstrated a reduction in peak vGRF and asymmetry in vGRF during drop landings with the inclusion of augmented feedback. The ACLr group demonstrated higher LR than the control group. Rehabilitation specialists may be able to incorporate targeted feedback as an intervention to help resolve landing asymmetries following ACLr.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
