研究离轴椭圆训练方案是否能减轻髌骨股痛（PFP）患者的疼痛并改善膝关节功能。控制实验室研究，前测试-后测试。大学康复中心。12名成年PFP患者。患有PFP的受试者使用定制的椭圆训练器完成了18次下肢离轴训练，该训练器允许脚板的前平面滑动和横平面旋转。使用膝关节损伤和骨关节炎结局评分（oos）和国际膝关节文献委员会（IKDC）评分评估训练后和训练后6周膝关节疼痛和功能的变化。通过旋转和滑动失稳来评估下肢离轴控制，以椭圆运动时踏板旋转角度和滑动距离的均方根（RMS）计算。评估受试者的单腿跳距和本体感觉对下肢旋转运动的感知能力。训练后，受试者的kos和IKDC得分显著提高（提高了12-18分），跳跃距离显著提高（提高了0.2米）。在训练后也观察到旋转和滑动RMS的显著下降。此外，在最小负重体位下测试时，PFP受试者表现出改善的旋转本体感觉。离轴椭圆训练方案可有效增强PFP患者下肢额、横平面神经肌肉控制，减轻疼痛，改善膝关节功能。
To examine whether an off-axis elliptical training program reduces pain and improves knee function in individuals with patellofemoral pain (PFP). Controlled laboratory study, pre-test-post-test. University rehabilitation center. Twelve adult subjects with PFP. Subjects with PFP completed an exercise program consisting of 18 sessions of lower extremity off-axis training using a custom-made elliptical trainer that allows frontal-plane sliding and transverse-plane pivoting of the footplates. Changes in knee pain and function post-training and 6 weeks following training were evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee (IKDC) scores. Lower extremity off-axis control was assessed by pivoting and sliding instability, calculated as the root mean square (RMS) of the footplate pivoting angle and sliding distance during elliptical exercise. Subjects’ single-leg hop distance and proprioception in detecting lower extremity pivoting motion were also evaluated. Subjects reported significantly greater KOOS and IKDC scores (increased by 12–18 points) and hop distance (increased by 0.2 m) following training. A significant decrease in the pivoting and sliding RMS was also observed following training. Additionally, subjects with PFP demonstrated improved pivoting proprioception when tested under a minimum-weight-bearing position. An off-axis elliptical training program was effective in enhancing lower extremity neuromuscular control on the frontal and transverse planes, reducing pain and improving knee function in persons with PFP.
