As the aging populations, both nationwide and worldwide, rapidly increase, falls leading to unintentional injury and death subsequently increase. Thus, developing an understanding of biomechanical postural control strategies used to maintai...
Effect of Aging and Cortical Stroke on Motor Adaptation to Overground Gait-Slips: Quantifying Differences in Adaptation Rate and Adaptation Plateau [0.03%]
老龄化和皮层中风对步态滑动的地上运动适应的影响：量化适应速率及平台期的差异

Rudri Purohit
We examined the effect of aging and cortical stroke on the rate of motor adaptation (adaptation rate) and amount of performance gains (adaptation plateau) in balance skills. Fourteen older (≥60 years) and fifteen younger ( 0.05). However, ...
Gait Kinematics and Asymmetries Affecting Fall Risk in People with Chronic Stroke: A Retrospective Study [0.03%]
慢性卒中患者步态动力学和影响跌倒风险的不对称性的回顾性研究
Shuaijie Wang,Tanvi Bhatt
Shuaijie Wang
Stroke survivors are at a relatively higher risk of falling than their healthy counterparts. To identify the key gait characteristics affecting fall risk in this population, this study analyzed the gait kinematics and gait asymmetries for 3...
Effects of Aging on Patellofemoral Joint Stress during Stair Negotiation on Challenging Surfaces [0.03%]
不同材质台阶对老年和年轻个体髌股关节应力的影响

Nicholas L Hunt et al.
This study examined the effect of age and surface on patellofemoral joint (PFJ) stress magnitude and waveform during stair ascent and descent tasks. A total of 12 young and 12 older adults had knee biomechanics quantified while they ascende...
Mechanics and energetics of human feet: a contemporary perspective for understanding mobility impairments in older adults [0.03%]
人类足部的力学和能量学：了解老年人行动不便的新视角
Kota Z Takahashi,Rebecca L Krupenevich,Amy L Lenz et al.
Kota Z Takahashi et al.
Much of our current understanding of age-related declines in mobility has been aided by decades of investigations on the role of muscle-tendon units spanning major lower extremity joints (e.g., hip, knee and ankle) for powering locomotion. ...
Reliability of the Fluoroscopic Assessment of Load-Induced Glenohumeral Translation during a 30° Shoulder Abduction Test [0.03%]
在肩关节外展30°试验中通过透视评估负荷诱发的肱盂关节移位的可靠性
Eleonora Croci,Marina Künzler,Sean Börlin et al.
Eleonora Croci et al.
Rotator cuff tears are often linked to superior translational instability, but a thorough understanding of glenohumeral motion is lacking. This study aimed to assess the reliability of fluoroscopically measured glenohumeral translation duri...
Margin of Stability May Be Larger and Less Variable during Treadmill Walking Versus Overground [0.03%]
跑步机上相对于地面行走的稳定边界可能更大且变化更小
Farahnaz Fallahtafti,Arash Mohammadzadeh Gonabadi,Kaeli Samson et al.
Farahnaz Fallahtafti et al.
Margin of stability (MOS) is considered a measure of mechanical gait stability. Due to broad application of treadmills in gait assessment experiments, we aimed to determine if walking on a treadmill vs. overground would affect MOS during th...
