站立弓步是一种常用的活动，用于通过透视量化体内的膝关节运动学。站立弓步的能力因受试者不同而不同，需要运动调节才能成功完成所需的运动范围。我们提出了仰卧腿按压作为站立弓步的替代方案，旨在提供类似的膝关节运动评估，同时增加测量的运动范围。53例无症状成人(男27例，女26例，年龄50.8±17.0岁)胫股运动学研究根据追踪的仰腿按压和站立挺举的高速立体摄影(HSSR)图像，使用CT分割的右下肢骨骼几何形状进行计算。仰卧压腿被证明是一种有用的替代站立弓步的方法，同时在屈膝时提供了46.2°的更大的活动范围。在100°屈曲范围内，内翻-外翻、内旋-外旋、内侧-外侧平移、前后平移、上下平移，男性的角度匹配运动学差异分别为0.70°、1.5°、1.0 mm、2.3 mm、0.46 mm。内翻外翻、内外旋2.4°、内外平移0.70 mm、前后平移2.1 mm、上下平移0.78 mm时，100°时角度匹配差为0.58°。类似的运动学，同时具有更大的运动范围，以及对所施加载荷的控制，使仰卧腿按压成为量化体内膝关节运动学的替代方案。
The standing lunge is an activity commonly used to quantify in-vivo knee kinematics with fluoroscopy. The ability to perform the standing lunge varies between subjects and can necessitate movement accommodations to successfully complete the desired range of motion. We proposed a supine leg press as an alternative to the standing lunge that aimed to provide a similar evaluation of knee motion while increasing the measured range of motion. Tibiofemoral kinematics of 53 non-symptomatic adults (27 men, 26 women, 50.8 ± 7.0 yrs.) were calculated from the tracked high-speed stereo radiography (HSSR) images for supine leg press and standing lunge using CT-segmented bony geometries of the right lower limb. The supine leg press proved to be a useful alternative to the standing lunge while providing 46.2° greater range of motion in knee flexion. The difference in angle-matched kinematics across a 100° flexion range between the leg press and lunge was 0.70° in varus-valgus rotation, 1.5° in internal-external rotation, 1.0 mm in medial–lateral translation, 2.3 mm in anterior-posterior translation, and 0.46 mm in superior-inferior translation for men. The angle-matched difference for women across 100° was 0.58° in varus-valgus rotation, 2.4° internal-external rotation, 0.70 mm medial–lateral translation, 2.1 mm anterior-posterior translation, and 0.78 mm superior-inferior translation. The similar kinematics, while having a greater range of motion, and control of the applied load makes the supine leg press an alternative for quantifying in-vivo knee kinematics.
