BACKGROUND
The Y-Balance test (YBT) is commonly used to evaluate balance after anterior cruciate ligament reconstruction (ACLR). However, several studies have also used it as a functional performance test (FPT).
PURPOSE
This study aimed to examine the relationship between YBT scores and measures of knee joint laxity, static balance, knee flexor and extensor torque and strength ratio, and FPTs.
STUDY DESIGN
Retrospective cohort study.
METHODS
Fifty-nine patients who underwent ACLR using hamstring autografts were retrospectively analyzed. The Pearson correlation coefficient was used to determine the strength of the association between scores on the YBT and selected outcomes including laxity measured via the KT-2000 arthrometer, static balance measured via the Biodex Balance System, isokinetic muscle torque and hamstring-to-quadriceps (HQ) ratio, and performance on the single leg hop test and the single leg vertical jump test.
RESULTS
Forty-six men and 13 women were included. The mean age and follow-up period were 29.6 ± 9.6 years and 12.4 ± 2.1 months, respectively. The KT-2000 arthrometer measures, Biodex Balance System scores, and HQ ratio measurements were not significantly correlated with the YBT scores. All YBT scores, except the YBT-anterior score, correlated with the isokinetic extensor and flexor torques (r-values: 0.271-0.520). All the YBT scores had significant weak to moderate correlations with the single leg hop test and single leg vertical jump test scores: YBT-anterior (r = 0.303, r = 0.258), YBT-posteromedial (r = 0.475, r = 0.412), YBT-posterolateral (r = 0.525, r = 0.377), and YBT-composite (r = 0.520, r = 0.412).
CONCLUSION
Post-ACLR YBT scores correlated with functional performance and muscle strength, but not with static balance, joint laxity, and HQ ratios. The YBT scores as a measure of balance are related to improved functional performance and isokinetic torque measures.
LEVEL OF EVIDENCE
背景
Y 平衡测试（YBT）常用于评估前交叉韧带重建（ACLR）后的平衡能力。然而，也有多项研究将其用作功能表现测试（FPT）。
目的
本研究旨在探讨 YBT 评分与膝关节松弛度、静态平衡、膝关节屈伸扭矩及力量比以及 FPT 各项指标之间的关系。
研究设计
回顾性队列研究。
方法
对 59 例行自体腘绳肌腱 ACLR 的患者进行回顾性分析。采用 Pearson 相关系数来确定 YBT 评分与选定结果之间的关联强度，选定结果包括通过 KT - 2000 关节测量仪测量的松弛度、通过 Biodex 平衡系统测量的静态平衡、等速肌肉扭矩和腘绳肌与股四头肌（HQ）比率，以及单腿跳测试和单腿垂直跳测试的表现。
结果
纳入 46 名男性和 13 名女性。平均年龄和随访时间分别为 29.6±9.6 岁和 12.4±2.1 个月。KT - 2000 关节测量仪测量结果、Biodex 平衡系统评分和 HQ 比率测量结果与 YBT 评分无显著相关性。除 YBT - 前向评分外，所有 YBT 评分均与等速伸肌和屈肌扭矩相关（r 值：0.271 - 0.520）。所有 YBT 评分与单腿跳测试和单腿垂直跳测试评分均具有显著的弱至中度相关性：YBT - 前向（r = 0.303，r = 0.258），YBT - 后内侧（r = 0.475，r = 0.412），YBT - 后外侧（r = 0.525，r = 0.377），以及 YBT - 综合（r = 0.520，r = 0.412）。
结论
ACLR 术后 YBT 评分与功能表现和肌肉力量相关，但与静态平衡、关节松弛度和 HQ 比率无关。作为平衡测量指标的 YBT 评分与功能表现改善和等速扭矩测量相关。
