BACKGROUND/PURPOSE: Anterior cruciate ligament reconstruction (ACLR) often leads to persistent neuromuscular deficits, complicating return-to-sport decisions. Reliable functional assessments are needed to guide RTS after ACLR. The main objective was to examine countermovement jump (CMJ) measures to identify which parameters can best distinguish between ACLR and control participants. The secondary objective was to determine whether performance alterations between operated and non-operated limb exist during CMJ after ACLR.
DESIGN
Non-randomized, single blinded, cross-sectional study.
METHODS
Limb symmetry index (LSI) was calculated for vertical ground reaction force (vGRF), maximal power (MP), and eccentric rate of force development (RFDe) during countermovement jumps (CMJ) performed on force plates by an ACLR group (n=64) and a control group (n=47). First analysis compared LSI vGRF, LSI MP and LSI RFDe between groups. Secondary analysis compared vGRF, MP and RFDe between the operated/non-operated limb in the ACLR group and dominant/non-dominant limb in the control group. Between-group comparisons were made using Mann-Whitney tests due to non-normal data distribution. Effect sizes were calculated to assess the magnitude of differences.
RESULTS
Participants included 64 ACLR patients (mean age 26.5 ± 5.0 years; 33 females) and 47 controls (mean age 23.6 ± 2.1 years; 24 females). CMJ measures in the ACLR group were significantly reduced for LSI vGRF (p < 0.001), LSI MP (p < 0.001) and LSI RFDe (p < 0.001). The ACLR group exhibited significant differences between both limbs in terms of vGRF (p < 0.001), MP ( p < 0.001), and RFDe (p < 0.01). No significant limb differences were found in the control group.
CONCLUSION
Measures of deceleration from the CMJ are altered after ACLR and should be considered throughout rehabilitation.
LEVEL OF EVIDENCE
背景/目的：前交叉韧带重建术（ACLR）常导致持续性神经肌肉功能缺陷，使恢复运动的决策变得复杂。需要可靠的功能评估来指导ACLR术后的恢复运动。主要目的是研究反向移动跳（CMJ）指标，以确定哪些参数能最佳区分ACLR患者和对照组参与者。次要目的是确定ACLR术后CMJ过程中，手术侧与非手术侧肢体的表现是否存在差异。
设计
非随机、单盲、横断面研究。
方法
通过力平台对ACLR组（n = 64）和对照组（n = 47）进行反向移动跳（CMJ），计算垂直地面反作用力（vGRF）、最大功率（MP）和离心力发展速率（RFDe）的肢体对称指数（LSI）。首次分析比较了两组之间的LSI vGRF、LSI MP和LSI RFDe。二次分析比较了ACLR组手术侧/非手术侧肢体以及对照组优势侧/非优势侧肢体的vGRF、MP和RFDe。由于数据分布不呈正态，组间比较采用曼-惠特尼检验。计算效应量以评估差异的大小。
结果
参与者包括64例ACLR患者（平均年龄26.5±5.0岁；33例女性）和47例对照组（平均年龄23.6±2.1岁；24例女性）。ACLR组的LSI vGRF（p < 0.）、LSI MP（p < 0.）和LSI RFDe（p < 0.）的CMJ指标显著降低。ACLR组在vGRF（p < 0.）、MP（p < 0.）和RFDe（p < 0.）方面，两侧肢体存在显著差异。对照组未发现显著的肢体差异。
结论
ACLR术后CMJ的减速指标发生改变，在整个康复过程中应予以考虑。
