大学运动员前交叉韧带（ACL）重建（ACLR）后，在跳跃和着陆任务中，通常观察到双侧垂直地面反作用力（VGRF）和膝关节伸展力矩不对称。着陆时的运动不对称与ACL再损伤风险增加有关。已经做出了努力，预测双侧运动不对称使用躯干运动学在深蹲，而不是在跳落。研究问题：确定ACLR术后大学生运动员双腿起跳时躯干运动学（肩关节内侧外侧位置、髋关节内侧外侧位置和躯干外侧弯曲角度）与双侧运动不对称性（VGRF和膝关节伸展力矩）之间的相关性。方法选取15名近24个月患有ACLR的全国大学体育协会一级运动员为研究对象。其中11人在研究期间进行了两次评估，总共进行了26次评估，用于数据分析。运动员进行了三个双腿反动作跳跃。收集了运动学和动力学数据。在跳跃（起飞前臀部最低位置）和着陆（初次接触后100毫秒）阶段，计算相对于踝关节位置的肩关节内侧外侧位置、躯干外侧弯曲角度和运动不对称性。结果中外侧肩位与跳跃阶段VGRF （r = 0.63, p < 0.001）和膝关节力矩不对称（r = 0.53, p = 0.006）相关。在跳跃和落地阶段，髋内外侧位与VGRF （r = 0.61, p < 0.001; r = 0.52, p = 0.006）和膝关节力矩不对称（r = 0.55, p = 0.004; r = 0.61, p < 0.001）相关。髋内外侧位置与ACLR术后大学生运动员双腿起跳时的运动不对称相关。使用标准摄像机进行二维评估可作为一种低成本且临床上适用的工具，通过量化ACLR后跳落时髋关节内侧-外侧位置来评估双侧动力学不对称。
BackgroundBilateral vertical ground reaction force (VGRF) and knee extension moment asymmetries are commonly observed during jumping and landing tasks following anterior cruciate ligament (ACL) reconstructions (ACLR) in collegiate athletes. Kinetic asymmetries during landings are associated with increased ACL re-injury risk. Efforts have been made to predict bilateral kinetic asymmetries using trunk kinematics during squats but not during jump-landings.Research questionTo determine the correlations between trunk kinematics (medial-lateral shoulder positions, medial-lateral hip positions, and lateral trunk bending angles) and bilateral kinetic asymmetries (VGRF and knee extension moments) during double-leg jump-landings in collegiate athletes following ACLR.MethodsFifteen National Collegiate Athletic Association Division I athletes who had ACLR in the past 24 months participated. Eleven of them performed two assessments over the study period for a total of 26 assessments for data analyses. Athletes performed three double-leg countermovement jumps. Kinematics and kinetics data were collected. Medial-lateral shoulder and hip positions relative to ankle positions, lateral trunk bending angles, and kinetic asymmetries were calculated during the jumping (the lowest hip position until takeoff) and landing (the first 100 ms after initial contact) phases.ResultsMedial-lateral shoulder positions correlated with VGRF (r = 0.63, p < 0.001) and knee moment asymmetries (r = 0.53, p = 0.006) in the jumping phase. Medial-lateral hip positions correlated with VGRF (r = 0.61, p < 0.001; r = 0.52, p = 0.006) and knee moment asymmetries (r = 0.55, p = 0.004; r = 0.61, p < 0.001) in both jumping and landing phases.SignificanceMedial-lateral hip positions correlated with kinetic asymmetries during double-leg jump-landings in collegiate athletes following ACLR. A 2D assessment using a standard video camera might be used as a low-cost and clinically applicable tool to assess bilateral kinetic asymmetries by quantifying medial-lateral hip positions during jump-landings following ACLR.
