Spine motion and outcome measures derived therein may be confounded by the motion instructions provided to participants during data collection. This observational analytical laboratory-controlled study explored the impact of instructions fo...
Validity of Poststroke Gait Spatiotemporal and Joint Excursion Metrics Between Inertial Measurement Units and a Marker-Based System [0.03%]
基于标记物系统的卒中后步态时空及关节摆动指标的惯性测量单元有效性研究
Heather L Knight,Ethan B Schonhaut,Camden J Jacobs et al.
Heather L Knight et al.
People with chronic stroke often walk with altered spatiotemporal parameters and joint excursions, metrics that can serve as intervention targets. Inertial measurement units (IMUs) allow such metrics to be quantified outside of a traditiona...
The Effects of Cheerleading Surfaces on Ankle Landing Characteristics During Vertical and Flip Landings [0.03%]
不同 Cheer 地面类型对垂直与翻转落地时的踝关节着地特性的影响研究
Anthony V Nguyen,Brooke A Slavens,Stephen C Cobb et al.
Anthony V Nguyen et al.
Lateral ankle sprains are common in cheerleading, especially during tumbling. Landing surfaces influence injury risk by affecting joint mechanics, but few studies compare vertical and flip landings. This study examined the effects of a hard...
Maximize or Normalize? Examining Single-Leg Drop-Land-Cut Distances in Young Athletes: A Pilot Study [0.03%]
最大化还是正常化？年轻运动员单腿下蹲距离的考察：一项初步研究
Anna J Butcher,Tracey Clissold,Sarah Ward et al.
Anna J Butcher et al.
This study investigated differences in leap distance for a single-leg drop-land-cut (CUT) task based on using either a maximal or normalized (150% leg length) method or the influence of condition order and leg dominance on distance achieved...
The Number of Gait Cycles Necessary to Obtain a Representative Measure of Knee Joint Loads in Individuals With Lower Limb Amputation [0.03%]
截肢者获得膝关节负荷代表性测量所需步态周期的数量

Katherine Collins et al.
Less dynamic limb-level loading is observed bilaterally in individuals who have undergone unilateral anterior cruciate ligament reconstruction (ACLR) and is linked with the development and progression of knee osteoarthritis. Experimentally ...
Head Acceleration Events Sustained During High School Wrestling Matches: Grappling With Differences Between Male and Female Adolescents [0.03%]
高中摔跤比赛中的头部加速事件：探究男女青少年之间的差异
Kenzie B Friesen,Zaryan Masood,Lyndia Wu et al.
Kenzie B Friesen et al.
Wrestling is a popular high school sport despite high injury and concussion rates. Instrumented mouthguards can reliably measure head acceleration events (HAEs) accrued by wrestlers and may highlight potential sex differences; important con...
How Oxygen Uptake, Ground Reaction Forces, and Kinematics Respond to Air Resistance and Drafting During Treadmill Running [0.03%]
跑台跑步时空气阻力和破风对摄氧量、地面反作用力以及运动学的影响
Jared R Steele,Luke VanKeersbilck,Dustin Bruening et al.
Jared R Steele et al.
This study investigated the effects of air resistance and drafting on oxygen uptake, ground reaction forces, and lower body kinematics during treadmill running. Thirty-three trained distance runners ran at 3.35 to 4.29 m/s (80%-85% of criti...
Effects of Different Inertial Measurement Unit Sensor-to-Segment Calibrations on Clinical 3-Dimensional Wrist Joint Angles Estimation [0.03%]
不同的惯性测量单元传感器-节段标定对临床三维腕关节角度评估的影响
