Technique and application for quantifying dynamic shoulder joint kinematics and glenohumeral joint contact patterns
The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics in 6-Degrees-of-Freedom (6-DOF) (translations and rotations) and …

The Bio-Mechanical Development and Kinematic Evaluation of Zone I and Zone II Injuries and their Corresponding Surgical Repair Techniques using an In-Vitro Active Finger Motion Simulator: A Cadaveric Study
Research development involving large scale joint mechanics and biomechanical adaptations is growing. However, interest in smaller scale joints, such as the fingers, is limited. Thus, the present work describes the enhancement and clinical application of a previously designed in-vitro active finger …

Validation and Examination of Upper Extremity Kinematics in Typically Developing Children During the Box and Blocks Functional Test using Marker-based and Markerless Technology
Joint kinematics of upper extremity (UE) impairments in a pediatric population are often difficult to examine using marker-based motion capture. As a result of the cost and availability of tools such as marker-based motion capture in clinical settings, clinicians use functional tasks to examine …

Appropriately complex biomechanical modelling of distance running
… using a fixed length segment, introducing a knee joint alone prevented successful simulations across the entire stance phase. In contrast, a model with passive knee and ankle joints resulted in good agreement between the experimental and simulated center of mass (CoM) trajectories. However, joint …
