Prescribing joint co-ordinates during model preparation in OpenSim improves lower limb unplanned sidestepping kinematics

Objectives - Investigate how prescribing participant-specific joint co-ordinates during model preparation influences the measurement agreement of inverse kinematic (IK) derived unplanned sidestepping (UnSS) lower limb kinematics in OpenSim in …

Identifying generalised segmental acceleration patterns that contribute to ground reaction force features across different running tasks

Objectives: To support future developments of field-based biomechanical load monitoring tools, this study aimed to identify generalised segmental acceleration patterns and their contribution to ground reaction forces (GRFs) across different running …

Whole-body biomechanical load in running-based sports: The validity of estimating ground reaction forces from segmental accelerations

Objectives: Unlike physiological loads, the biomechanical loads of training in running-based sports are still largely unexplored. This study, therefore, aimed to assess the validity of estimating ground reaction forces (GRF), as a measure of external …

Can segmental model reductions quantify whole-body balance accurately during dynamic activities?

When investigating whole-body balance in dynamic tasks, adequately tracking the whole-body centre of mass (CoM) or derivatives such as the extrapolated centre of mass (XCoM) can be crucial but add considerable measurement efforts. The aim of this …

Performance of a lateral pelvic cluster technical system in evaluating running kinematics

Valid measurement of pelvic and hip angles during posterior load carriage gait task requires placement of pelvic markers which will not be occluded or physically displaced by the load. One solution is the use of pure lateral pelvic clusters to track …

Multi-segment foot landing kinematics in subjects with chronic ankle instability

Background: Chronic ankle instability has been associated with altered joint kinematics at the ankle, knee and hip. However, no studies have investigated possible kinematic deviations at more distal segments of the foot. The purpose of this study was …

The reliability of the ELEPAP clinical protocol for the 3D kinematic evaluation of upper limb function

Upper limb (UL) kinematic assessment protocols are becoming integrated into clinical practice due to their development over the last few years. We propose the ELEPAP UL protocol, a contemporary UL kinematic protocol that can be applied to different …

Impact of Knee Modeling Approach on Indicators and Classification of Anterior Cruciate Ligament Injury Risk:

The aim of this study was to determine whether using a direct kinematic (DK) or inverse kinematic (IK) modeling approach could influence the estimation of knee joint kinematics, kinetics, and ACL injury risk classification during unanticipated side …

Gait Kinematics of Subjects with Ankle Instability Using a Multisegmented Foot Model:

An evaluation of anatomical and functional knee axis definition in the context of side-cutting

Side-cutting is commonly used to evaluate knee joint kinematics and kinetics in the context of anterior cruciate ligament injury risk. Many existing side-cutting studies fail to clearly define the orientation of the femoral frame and the knee axis, …
