Abstract

Background: The restoration and management of the uninvolved side have been emphasized to prevent a second anterior cruciate ligament (ACL) injury and to ensure that athletes return to sports after ACL reconstruction.

Objective: To determine the factors influencing the single leg hop test (SLHT) and single leg vertical jump test (SLVJT) at 1 year postoperatively after ACL reconstruction in both the involved and uninvolved sides.

Methods: Ninety-four patients who underwent ACL reconstruction were assessed at 1 year postoperatively. Multiple regression models included eight independent variables with two dependent variables (SLHT and SLVJT.), each on the involved and uninvolved side.

Results: On the involved side, the Y balance test (YBT), extensor peak torque per body weight (PT/BW), Biodex balance system anteroposterior index (BBS-API), and sex accounted for 53.9% of the variance in SLHT (P= 0.002), and extensor PT/BW and YBT accounted for 26.3% of the variance in SLVJT (P= 0.027). On the uninvolved side, YBT, sex, age, BBS-API, and flexor PT/BW accounted for 47.0% of the variance in SLHT (P= 0.046), and flexor PT/BW, YBT, and age accounted for 44.9% of the variance in SLVJT (P= 0.002).

Conclusion: Knee extensor strength on the involved side and flexor strength on the uninvolved side influence the two functional performance tests. The YBT was an important factor in the two functional performance tests in both sides. Anteroposterior stability was the only factor that influenced the SLHT bilaterally.

前交叉韧带重建术后力量和平衡能力对受累侧和非受累侧功能表现的影响。

背景：为了防止第二前交叉韧带（ACL）损伤，并确保运动员在ACL重建后重返赛场，已经强调了对未参与侧的恢复和管理。目的：探讨影响ACL重建术后1年患侧和非患侧单腿跳跃试验（SLHT）和单腿垂直跳跃试验（SL VJT）的因素。方法：对94例ACL重建患者术后1年进行评估。多元回归模型包括八个自变量和两个因变量（SLHT和SLVJT），每个都在参与方和非参与方。结果：在受累侧，Y平衡试验（YBT）、每体重伸肌峰值扭矩（PT/BW）、Biodex平衡系统前后指数（BBS-API）和性别占SLHT方差的53.9%（P=0.002），伸肌PT/BW和YBT占SLVJT方差的26.3%（P=0.027），屈肌PT/BW占SLHT方差的47.0%（P=0.046），屈肌PT/BW、YBT和年龄占SLVJT方差的44.9%（P=0.002）。YBT是双方两次功能性能测试中的一个重要因素。前后位稳定性是影响双侧SLHT的唯一因素。

期刊介绍： The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
