The Influence of Obesity and Body Shape on Sagittal Plane Knee Kinematics and Kinetics during Obstacle Crossing

This study examines how obesity and body shape affect knee biomechanics during obstacle crossing, finding greater knee extension moments in obese individuals and shape-specific differences in knee angles.

Estimating Body Segment Properties for Adults AcrossDiverse Body Morphologies: A Data-Driven GeometricFramework

This paper develops a data-driven framework to estimate body segment inertial properties across diverse adult body morphologies, outperforming existing methods, especially for higher BMI values.

Predictive Neuromechanical Simulation Explains Gait Biomechanics in Obesity

This study uses predictive neuromechanical simulations to show that obesity-related gait changes and knee loading are influenced by both body mass distribution and objectives that penalize knee loading.
