Finite element models can predict subject-specific chondrolabral stresses and help to elucidate the effect of under-coverage and incongruency of the hip joint in patients with dysplasia. However, complex stress patterns are difficult to generalize and evaluate statistically. With an established correspondence across shapes from statistical shape modeling (SSM), statistical parametric mapping (SPM) allows for evaluation of local variability while preserving model subject-specificity. Herein, we evaluated the combined application of SSM and SPM to compare cartilage contact stress between control subjects and patients with dysplasia.

Previously published hip joint contact stresses were mapped onto chondrolabral surface meshes and incorporated into an …

Developmental dysplasia of the hip (DDH) is described as under-coverage of the femoral head by the acetabulum, resulting in mechanical instability. Though DDH is often diagnosed using plain film radiographs, these images cannot adequately capture 3D joint coverage. Herein, we applied a 3D statistical shape model (SSM) to the femur and hemi-pelvis of patients with DDH to objectively measure shape variation and evaluated whether SSM outputs could predict measurements of joint coverage.

The femur and hemi-pelvis were semi-automatically segmented from CT images (83 hips from 47 females with DDH). Surfaces of each hip were reconstructed from segmentations, aligned, and input …

Mammalian And Invertebrate Models As Complementary Tools For Gaining Mechanistic Insight On Muscle Responses To Spaceflight, Amber M. Paul, Thomas Cahill, Henry Cope, Joseph J. Bass, Eliah G. Overbey, Rachel Gilbert

Publications

Bioinformatics approaches have proven useful in understanding biological responses to spaceflight. Spaceflight experiments remain resource intensive and rare. One outstanding issue is how to maximize scientific output from a limited number of omics datasets from traditional animal models including nematodes, fruit fly, and rodents. The utility of omics data from invertebrate models in anticipating mammalian responses to spaceflight has not been fully explored. Hence, we performed comparative analyses of transcriptomes of soleus and extensor digitorum longus (EDL) in mice that underwent 37 days of spaceflight. Results indicate shared stress responses and altered circadian rhythm. EDL showed more robust growth signals …

Novel Computational Infant Musculoskeletal Model For Biomechanical Analysis Of Infant Movement, Yeram Lim

Doctoral Dissertations and Master's Theses

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 musculoskeletal model for biomechanical analysis of infant movement. For this study, 31 reflective markers were placed on an infant, and marker-based motion capture data was collected. The computational study used a generic GAIT2392 OpenSim musculoskeletal model that was scaled to create a customized subject-specific infant model. By using the motion capture data recorded of the infant during a kicking motion, …

This ergonomics assessment focused on a female Licensed Practical Nurse (LPN) and her life inside and outside of her job. In particular, this case study assessed how working as a nurse may affect the human body in terms of Musculoskeletal Disorders (MSDs). The researcher first conducted an in-depth interview with the nurse about her workplace layout, typical daily work schedule, work habits, physical challenges, MSD injuries she has sustained, and the workplace environment/organizational culture. Next, the researcher conducted three MSD …
