Development and Application of a BioRobotic Simulation of Stance Phase Gait to Study Foot and Ankle Kinematics
<p>Ankle instantaneous axis of rotation (IAR) measurements represent a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a …

The Relationship between Dorsiflexion Range of Motion and Knee Kinematics in a Land-and-Jump Task
… dorsiflexion range of motion and frontal knee kinematics at initial ground contact and maximal knee flexion in a land-and-jump task. Thirteen male participants (age = 23 + 2.35 y, height = 181.4 + 5.68 cm, mass = 84.5 + 17.2 kg) proficient in landing and jumping techniques and free from lower …

A comparison of human walking using a conventional gait laboratory and the Motek Medical Computer Assisted Rehabilitation Environment (CAREN)
… sensations during the two walks. The knee kinematics measured showed that they are not affected by the change in environment, while the ankle kinematics showed significantly different results for the various walking conditions, such that it was speculated that this gait parameter varies in …

An Innovative Testing Protocol to Study Foot and Ankle Kinetics during Early Stance Phase of Gait
… platform limitations with respect to foot and ankle mechanics in the sagittal plane during dorsiflexion and plantar flexion. The intent was to develop a multi-loading protocol that simulated aspects of early stance phase of walking gait. This data were used to evaluate the influence an Achilles …

Biomechanical Analyses of Head Acceleration during Contact Sports and Ankle Joint Complex Injury
… in bodily injuries, such as concussions and ankle sprains. This research is divided into two separate biomechanical studies: the design and evaluation of a device to simulate football helmet collisions and its parameters, and a cadaveric study to investigate the effects of ankle sprains. An …

A 3D neuromuscular model of the human ankle-foot complex based on multi-joint biplanar fluoroscopy gait analysis
During the gait cycle, the human ankle complex serves as a primary power generator while simultaneously stabilizing the entire limb. These actions are controlled by an intricate interplay of several lower leg muscles that cannot be fully uncovered using experimental methods alone. A combination of …

An investigation of potential kinematic factors associated with patellofemoral pain syndrome during running
… equivocal evidence for differences in lower limb kinematics in participants with PFPS, particularly during the running gait cycle. The aim of this study was to investigate lower extremity kinematics during running in individuals with a history of PFPS compared to those without symptoms. Specific …

A Dynamic Ankle Orthosis for Alleviating Mechanical Foot and Ankle Pain, Preserving Joint Motion, and Restoring Patient Function
… visit the doctor each year for foot and ankle pain stemming from a degenerative condition or injury. Standard of care ankle-foot orthoses have been shown to effectively manage pain symptoms of the lower limb, but they can also significantly hinder joint motion and limit function. The …

EMG-Informed Estimation of Human Walking Dynamics for Assistive Robots
… was to predict the motion and moments of the ankle joint during a range of different walking conditions. As such, a set of experiments was designed to collect motionrelated data from 10 individuals during a wide range of activities. Initially, an artificial neural network was designed to …

An investigation of the biomechanical efficacy and clinical effectiveness of patello-‐femoral taping in elite and experienced cyclists
… showed significant differences in the knee, ankle and hip kinematics between cyclists with and without knee pain. The knee had increased ROM (coronal) in those with knee pain (p=0.005 or 18% change) whereas in the hip, those with knee pain had less movement (p=0.001 or 26% change). The ankle …

Towards an improved understanding of the biomechanical implications and risk of injury of barefoot running
… barefoot trials. We found that an increase in ankle dorsiflexion is associated with an increase in initial loading rate when in the barefoot condition, supporting previous findings in this regard. We then performed a supervised, pure barefoot running training programme, over 8 weeks, to …

Effects of prophylactic lace-up ankle braces on kinetics and kinematics of the lower extremity during a state of fatigue.
… are commonly used on athletes regardless of ankle injury history to reduce lateral ankle sprains (LAS). However, their ability to limit ankle sagittal range of motion has the potential to alter knee kinematics and is linked to chronic knee pathologies. Thirteen college-aged (6 males) and (7 …
