Novel Computational Infant Musculoskeletal Model for Biomechanical Analysis of Infant Movement
<p>Computational musculoskeletal models are increasing in commonality and popularity in the study of biomechanics. These models, however, are mainly used to represent fully developed adults, while infant musculoskeletal models are nonexistent. This study aims to develop a novel computational infant …

Prediction of knee loading in native knee and total knee arthroplasty : a forward dynamics computational study
"The goal of this dissertation is to develop a musculoskeletal model and corroborate model predictions to experimentally measured in vivo knee contact forces, in order to study the biomechanical consequences of two different total knee arthroplasty designs. The two main contributions of this …

Biomechanical simulation of virtual physiological humans : modeling of musculoskeletal kinematic and dynamic redundancy using coordinate projection methods
The principles of musculoskeletal model and simulation have received much attention over the last decades, enabling the prediction of surgical treatments related to different motion limiting disorders. However, their application in clinical practice is still limited partly because the experimental …

An investigation of perturbation-based balance training as a fall prevention intervention for older adults
… in older adults. A torque-driven, three-segment, musculoskeletal model and forward dynamic simulations were used to address the hypothesis. Increasing joint strength was beneficial in recovering balance from a postural perturbation only after re-optimization of the torque activation. These results …
