Effect Of Arm Movement On Lower Body Muscle Contributions To Standing Long Jump Performance, Abigail Douglas
Effect Of Arm Movement On Lower Body Muscle Contributions To Standing Long Jump Performance, Abigail Douglas
Masters Theses
Previous jumping studies have proven that jumping with arm motion enhances performance compared to jumping without arm motion. The purpose of this study was to investigate the effect of arm motion on the muscle contributions of the lower extremities during the standing long jump using muscle-actuated modeling informed by experimental data. Specifically investigating how arm motion enhances performance at the muscle level and how the muscle contributions of the lower extremities differ in jumps with and without arm motion. Three male and three female participants performed three jumps with arms and three jumps without arms. The longest jumps with and …
Opensim Analysis Of The Aymara Indigenous People Performing Ancestral Tasks: Exploring Trends Of Muscle Activity With Tiwanaku Skeletal Indicators, Noah M. Taylor
Master's Theses
The Tiwanaku civilization (AD 500-1100) of the Andean highlands exhibited occupational specialization in communities, with archeological evidence suggesting the existence of labor- and residential-communities, or “taskscapes”, based on an individual’s livelihood. Prior bioarcheological studies have examined Tiwanaku skeletal remains for musculoskeletal stress markers, osteoarthritis, and cross-sectional geometry to infer activity patterns. Their descendants, the Aymara Indigenous people, currently live in the same highlands and until recently lived a lifestyle like their ancestors. Over the past 20 years, the global quinoa demand has risen, thrusting the Aymara into globalization and moving them away from the traditional tasks previously performed. This study …
Defining Sagittal Plane Gait Mechanics And Joint Loading In People With Marfan Syndrome, Justin Melan Pol
Defining Sagittal Plane Gait Mechanics And Joint Loading In People With Marfan Syndrome, Justin Melan Pol
Theses and Dissertations--Biomedical Engineering
Marfan syndrome (MFS) is a genetic condition that is associated with altered muscle composition, which leads to muscle dysfunction. People with MFS exhibit high instances of lower extremity (LE) joint pain that inhibits their ability to perform activities of daily living, such as walking. Despite these detrimental impacts of MFS, there have been no attempts to characterize the effects of MFS on LE joint loading and health during walking that are associated with LE pain and dysfunction. As people with MFS exhibit a high incidence rate of osteoarthritis (OA), the need to understand the potential alterations in LE extremity mechanics …
Interactive Software-Based Modeling For Gait Analysis Of Musculoskeletal Structures, Nada Masood Mirza, Adnan Ali, Mohamad Khairi Ishak
Interactive Software-Based Modeling For Gait Analysis Of Musculoskeletal Structures, Nada Masood Mirza, Adnan Ali, Mohamad Khairi Ishak
Makara Journal of Technology
Software for interactive musculoskeletal modeling applies diverse scientific and technological concepts to stimulate the movement of musculoskeletal figures. Several tools are available for biomechanical analysis in studying motion and capturing the musculoskeletal representation data to facilitate further evaluation for muscle activation. Musculoskeletal software, such as the OpenSim model, animates, and measures in 3D the structural movement of bones, muscles, joints, ligaments, and such structures in the human body. Users apply graphical interfaces to manipulate the movement science for fast and accurate analysis. OpenSim simulation software features a user-friendly interface to allow the proper clinical application in biomechanics and rehabilitation research. …
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 …
Musculoskeletal Modeling Of The Pelvis And Lumbar Spine During Running, Ruth Higgins, Maryam Moeini, Hunter Bennett, Stacie Ringleb
Musculoskeletal Modeling Of The Pelvis And Lumbar Spine During Running, Ruth Higgins, Maryam Moeini, Hunter Bennett, Stacie Ringleb
College of Engineering & Technology (Batten) Posters
Musculoskeletal modeling provides an alternative to in-vivo characteristics that are difficult to directly measure for movements such as running, especially for trunk muscles and joints. The full-body-lumbar-spine (FBLS) model by Raabe and Chaudhari, 2016 is an OpenSim model created for simulations of jogging. The lifting full-body (LFB) model by Beaucage-Gauvreau et al., 2018 is an adaptation of the FBLS created for estimating spinal loads during lifting. PURPOSE: Determine validity of the FBLS and LFB models in simulating pelvis and lumbar spine kinematics during running. METHODS: Inverse Kinematics were executed using experimental data for the FBLS and LFB models. To …
Utilizing Neural Networks And Wearables To Quantify Hip Joint Angles And Moments During Walking And Stair Ascent, Megan V. Mccabe
Utilizing Neural Networks And Wearables To Quantify Hip Joint Angles And Moments During Walking And Stair Ascent, Megan V. Mccabe
ENGS 88 Honors Thesis (AB Students)
Wearable sensors were leveraged to develop two methods for computing hip joint angles and moments during walking and stair ascent that are more portable than the gold standard. The Insole-Standard (I-S) approach replaced force plates with force-measuring insoles and achieved results that match the curvature of results from similar studies. Peaks in I-S kinetic results are high due to error induced by applying the ground reaction force to the talus. The Wearable-ANN (W-A) approach combines wearables with artificial neural networks to compute the same results. Compared against the I-S, the W-A approach performs well (average rRMSE = 18%, R2 …
Evaluating The Effects Of Muscle Force Production Strategies And Anterior Cruciate Ligament Forces (Strain) On Gait Patterns During Running, Amanda Astrologo
Evaluating The Effects Of Muscle Force Production Strategies And Anterior Cruciate Ligament Forces (Strain) On Gait Patterns During Running, Amanda Astrologo
Honors Scholar Theses
Anterior cruciate ligament (ACL) injuries are among the most common injuries experienced by athletes in the United States. Even after reconstruction surgery individuals have been known to develop complications much later in life, including long-term or permanent alterations to their gait, which may lead to early-onset knee osteoarthritis. This thesis work sought to define these alterations as they pertain specifically to running. Using results and parameters from previous studies, the goal of this study is to compare muscle force production strategies, as they relate to ACL force and strain, of injured and non-injured individuals. These values, muscle forces and ACL …
Finite Element Models Of The Knee & Hip Joints: Using Opensim To Predict Muscle Forces, Kevin S. Jones, Spencer D. Wangerin, Jeffrey D. Pyle, Stephen M. Klisch, Scott J. Hazelwood
Finite Element Models Of The Knee & Hip Joints: Using Opensim To Predict Muscle Forces, Kevin S. Jones, Spencer D. Wangerin, Jeffrey D. Pyle, Stephen M. Klisch, Scott J. Hazelwood
STAR Program Research Presentations
Quantitative data of stresses and strains in the cartilage of the knee and hip joints are required to design prostheses and can be used to give accurate advice to patients with cartilage damage as to which activities should be avoided. Instrumented hip implants can only give the overall resultant force in the joint, not the stresses and strains throughout the cartilage. Finite Element (FE) models of the Knee and Hip are being constructed in order to obtain the stresses and strains in articular (of the joint) cartilage. Muscle forces and joint contact forces are required as inputs to these FE …
