Risk Factors for Knee Injuries in Children 8 to 15 Years: The CHAMPS Study DK
KNEE INJURIES CHILDREN RISK FACTORS YOUTH SPORTS
2017/4/13
Introduction: Knee injuries are frequent in children, with most studies reporting traumatic knee injuries. Evidence of risk factors for knee injuries in children is sparse. The purpose of this study w...
Multi-Axis Prosthetic Knee Resembles Alpine Skiing Movements of an Intact Leg
Above-knee amputation Alpine skiing impairment kinematics prosthesis
2016/2/23
The purpose of the study was to analyse the flexion angles of the ski boot, ankle and knee joints of an above-knee prosthesis and to compare them with an intact leg and a control group of skiers. One ...
The Waist Width of Skis Influences the Kinematics of the Knee Joint in Alpine Skiing
Abduction inertial sensor rotation ski turn three-dimensional joint movements
2016/1/9
Recently alpine skis with a wider waist width, which medially shifts the contact between the ski edge and the snow while turning, have appeared on the market. The aim of this study was to determine th...
Energy Cost and Gait Efficiency of Below-Knee Amputee and Normal Subject with Similar Physical Parameters & Quality of Life: A Comparative Case Study
Energy Cost Gait Efficiency Below knee amputee
2015/7/15
The study focused on the comparative analysis of energy cost and gait efficiency between a below knee (BK) amputee and a reference subject (without amputation). It also attempted to indicate the speci...
Efficacy of Home-Based Kinesthesia, Balance & Agility Exercise Training Among Persons with Symptomatic Knee Osteoarthritis
Exercise therapy rehabilitation postural balance resistance training
2015/5/13
The purpose of this study was to determine the efficacy of a home-based kinesthesia, balance and agility (KBA) exercise program to improve symptoms among persons age ≥ 50 years with knee osteoarthriti...
In Vivo Kinematics of the Anterior Cruciate Ligament Deficient Knee During Wide-Based Squat Using a 2D/3D Registration Technique
2D/3D registration technique anterior cruciate ligament deficient knee in vivo knee kinematics wide-based squat activity
2015/5/13
Anterior cruciate ligament (ACL) deficiency increases the risk of early osteoarthritis (OA). Studies of ACL deficient knee kinematics would be important to reveal the disease process and therefore to ...
Muscle activity response to external moment during single-leg drop landing in young basketball players: The importance of biceps femoris in reducing internal rotation of knee during landing
ACL injury risk factors knee moment muscle activation.
2015/5/11
Internal tibial rotation with the knee close to full extension
combined with valgus collapse during drop landing generally
results in non-contact anterior cruciate ligament (ACL) injury.
Frontal plane knee moments in golf: Effect of target side foot position at address
Golf ACL injury biomechanics knee abduction (valgus) moment/torque
2015/5/5
Golf has the potential to keep people active well into their later
years. Injuries to the target side knee have been reported in
golfers, yet no mechanisms for these injuries have been proposed.
Arthrometric Evaluation of Stabilizing Effect of Knee Functional Bracing at Different Flexion Angles
Functional brace knee ACL injury
2015/4/22
Previous in-vivo investigations on the stabilizing efficacy of knee bracing for ACL reconstructed patients have been often limited to 20-30 degrees of knee flexion. In this study, the effectiveness of...
CO2 Clamping, Peripheral and Central Fatigue during Hypoxic Knee Extensions in Men
BRAIN CARBON DIOXIDE HYPOXIA NEUROMUSCULAR FATIGUE
2017/4/20
The central nervous system can play a critical role in limiting exercise performance during hypoxic conditions. Hypocapnia, which is associated with hypoxia-induced hyperventilation, may affect cerebr...
Longitudinal Increases in Knee Abduction Moments in Females during Adolescent Growth
ACL INJURY NEUROMUSCULAR CONTROL IMBALANCE INJURY PREVENTION SEX DIFFERENCES
2017/4/20
Knee abduction moment (KAM) is an injury risk factor for anterior cruciate ligament (ACL) injury that shows divergent incidence between males and females during adolescence. The objective of this stud...

RESISTANCE TRAINING EXERCISE BLOOD FLOW RESTRICTION FATIGUE DIFFUSE OPTICS TISSUE OXYGENATION
2017/4/14
Purpose: Time-resolved near-infrared spectroscopy was used to quantify tissue oxy- and deoxyhemoglobin concentrations ([HbO2] and [HbR]) and O2 saturation (stO2) in the oblique fibers of the vastus me...
Multiplanar Knee Laxity Increases during a 90-min Intermittent Exercise Protocol
SOCCER JOINT SEX COMPARISON, ACL INJURY BIOMECHANICS RISK FACTOR
2017/7/17
Purpose: This study aimed to examine changes in sagittal (APLAX), frontal (VVLAX), and transverse (IERLAX) plane knee laxity in men and women during an intermittent exercise protocol (IEP) simulating ...
The Reliability of Portable Fixed Dynamometry During Hip and Knee Strength Assessments
isometric activity lower extremity
2010/9/8
Insufficient lower extremity strength may be a risk factor for lower extremity injuries such as noncontact anterior cruciate ligament tears. Therefore, clinicians need reliable instruments to assess s...
