Subtalar Joint Definition In Biomechanical Models, Julia Noginova
Subtalar Joint Definition In Biomechanical Models, Julia Noginova
Biomedical Engineering Theses & Dissertations
The effect of including a subtalar joint in a dynamic musculoskeletal model has not been fully explored or validated. The subtalar joint is often modeled as a one DOF hinge with the tri-planar axis defined as a combination of inclination and deviation angles measured from the ground and midline of the foot, respectively. The overall purposes of this dissertation were to explore how the inclusion of the subtalar joint and the definition of origin location and axis orientation affect the kinematics, joint kinetics, and muscle activations of the knee, ankle, and subtalar joint during dynamic tasks of walking and running …
Generation, Analysis, And Evaluation Of Patient-Specific, Osteoligamentous, Spine Meshes, Austin R. Tapp
Generation, Analysis, And Evaluation Of Patient-Specific, Osteoligamentous, Spine Meshes, Austin R. Tapp
Biomedical Engineering Theses & Dissertations
Scoliosis, an abnormal curvature of the spine, is traditionally corrected with bracing treatments or by a highly invasive posterior spinal fusion (PSF) operation. These correction strategies are constrained by current imaging modalities, which fail to elucidate the soft tissue anatomy that is known to play a critical role in spinal stiffness and overall structure. Osteoligamentous segmentations of the spinal column offer a foundation for downstream finite element (FE) studies seeking to optimize bracing treatments or determine ideal surgical approaches.
This thesis presents methods for automatically and semi-automatically segmenting vertebrae and surrounding soft tissues of the spinal column using X-ray computed …

Molecular Dynamics Simulations Of Ion Transport Through Electrically Stressed Biological Membranes, Federica Castellani
Biomedical Engineering Theses & Dissertations
The cell membrane is a selectively permeable barrier that controls the transport of ions, molecules, and other materials into and out of a cell. The manipulation of the cell membrane permeability is the basis for several biotechnological and biomedical applications, including electroporation. Electroporation (or electropermeabilization) occurs when the application of an external electric pulse causes water intrusion into the membrane interior and the formation of conductive transmembrane electropores. These electropores allow drugs, genetic material, and other normally impermeant molecules to enter a cell. Despite years of study, the complex mechanisms underlying this process are still not well understood. Molecular dynamics …
Integrative Computational Analysis Of Muscle Near-Infrared Spectroscopy Signals: Effects Of Oxygen Delivery And Blood Volume, Bhabuk Koirala
Integrative Computational Analysis Of Muscle Near-Infrared Spectroscopy Signals: Effects Of Oxygen Delivery And Blood Volume, Bhabuk Koirala
Biomedical Engineering Theses & Dissertations
Near-infrared spectroscopy (NIRS) is a non-invasive technology to evaluate skeletal muscle oxidative metabolism in healthy and disease states. This technology allows us to measure the dynamic response of oxygenated (Δ����������2) and deoxygenated (Δ����������) heme group concentrations during muscle contraction. These O2 kinetics are valuable for inferring the interplay between muscle oxygen delivery and utilization. However, the semi-quantitative nature of the NIRS signal limits its clinical application. Some of the challenges in interpreting the NIRS signal are related to the difficulties in quantifying the: 1) contribution of blood volume changes to the Δ����������2 and Δ����������; 2) contribution …
Drive Leg And Stride Leg Ground Reaction Forces Relationship To Medial Elbow Stress And Velocity In Collegiate Baseball Pitchers, Brett Smith
Biomedical Engineering Theses & Dissertations
This study examines several different kinetic variables in relation to pitch velocity and elbow varus torque in collegiate baseball pitchers using force plates, an inertial measurement unit, and a radar unit. The purpose of this study is to investigate the kinetic variables being measured and their relationship to pitch velocity and loads being placed on the medial elbow. Twelve collegiate baseball pitchers participated in this study, which was approved by the IRB. Impulse of the drive leg in the anterior-posterior direction, stride leg peak force in the anterior-posterior (AP) direction, elbow varus torque, and pitch velocity were all measured. Two …
