Jacquelyn R Brokamp et al.
Ankle-foot orthoses (AFOs) are commonly prescribed to improve gait in individuals with neuromuscular and musculoskeletal impairments; however, no standardized protocols exist to characterize their mechanical properties, including fatigue li...
Femoral neck anteversion alters patellofemoral joint mechanics during walking: insights from musculoskeletal modeling and Monte Carlo simulations [0.03%]
股骨颈前倾改变步态中的髌股关节力学：来自运动学建模和蒙特卡罗模拟的见解

Joint moments derived from inverse dynamics are widely used to infer muscular demand during walking. While low-pass filtering of kinematic and kinetic data is essential, the choice of cutoff frequency combinations varies substantially and c...
Differences in running kinematics and stride-to-stride variability between self-paced treadmill and overground running on two surfaces [0.03%]
不同速度的跑步运动学与步进式变化：在两种地面对自控调速跑步机和体外跑步之间的差异性研究
