Comparative Assessment Of Lower Limb Neuromusculoskeletal Activation And Joint Kinematics In Normal And Impaired Gait, Jack Ryan Schule

Theses and Dissertations

This thesis evaluates whether accessible and affordable technologies can provide clinically significant, quantifiable gait analysis comparable to traditional marker-based motion capture systems. Modern high-end systems offer excellent accuracy but remain financially and logistically inaccessible to many clinicians and researchers. To address this gap, a framework was developed using markerless pose estimation using the model, MediaPipe, inertial measurement units (IMUs) processed through an Extended Kalman Filter (EKF), and surface electromyography (sEMG) to measure joint kinematics and neuromuscular activity during gait. An experiment was performed where data was collected from participants with both normal gait and pathologies including: Osgood–Schlatter disease, Plica Band …

High Phosphorus Intake: The Role Of Phosphorus And Health Outcomes Through The Lens Of High Phosphorus Additive Intake, Taigen M. Mayes

Senior Honors Theses

Phosphorus is a commonly consumed mineral in the traditional human diet and plays an essential role in human physiological functions. With the use of phosphate additives, high phosphate intake has become increasingly prevalent in recent years. Phosphate is regulated in the body by a homeostasis mechanism. A disruption to the homeostasis has a link to various pathologies such as bone health, cardiovascular disease, cancers, and kidney issues. Various studies have investigated the role of phosphate and its effects on human function. Bone health, cardiovascular disease, cancer, premature aging, dementia, and kidney disease are linked with high phosphorus intake.

I want to go into Medical Illustration, and I want to make science easier for people to learn. To do this I want to take complicated subjects and remake them into simpler terms. For my capstone, I decided to take anatomy of the arm, leg, and abdominal organs and draw them on professional women athletes. I thought that expressing this anatomy in less of a clinical way is one strategy to make …

Rebound Bursting Selectively Enables Fast Dynamics In Dopamine Midbrain Neurons Projecting To The Dorsolateral Striatum, Strahinja Stojanovic, Christopher J. Knowlton, Richard Egger-Mackrodt, Johanna Mankel, Josef Shin, Stephan Lammel, Carmen C. Canavier, Jochen Roeper

School of Graduate Studies Faculty Publications

Dopamine (DA) midbrain neurons are involved in a wide array of key brain functions including movement control and reward-based learning. They are also critical for major brain disorders such as Parkinson's disease or schizophrenia. DA neurons projecting to distinct striatal territories are diverse with regard to their molecular makeup and cellular physiology, which are likely to contribute to the observed differences in temporal DA dynamics. Among these regions, the dorsolateral striatum (DLS) displays the fastest DA dynamics, which might control the moment-to-moment vigor and variability of voluntary movements. However, the underlying mechanisms for these DLS-specific fast DA fluctuations are unresolved. …

Introducing Patient-Centered Outcomes To Preceptors In Caate-Approved Athletic Training Programs, K. Judge

Clinical Practice in Athletic Training

The 2020 standards set by the Commission on Accreditation of Athletic Training Education (CAATE) now require the incorporation of the International Classification of Function and Patient-Centered Outcomes into professional practice. These standards can be introduced initially through simulation, but to develop a competent and culturally aware professional, outcome measures should be completed during clinical experiences under the guidance of approved preceptors. As this is a relatively new standard, many preceptors did not receive this as part of their education and may be uncomfortable integrating outcomes into their practice. This lack of integration can negatively affect the learning opportunities of athletic …

Impact Of A Focused Best Practice Workshop On Athletic Trainer Confidence, Jaclyn B. Arduini, Jennifer L. Volberding, Zachary A. Murray

Clinical Practice in Athletic Training

Athletic trainers are required to be proficient in emergency management skills, without review these skills may decay creating a potentially dangerous knowledge gap. Confidence measures of emergency management skills were taken before and after a workshop to determine if they changed due to the review of material. All 11 confidence measures increased post workshop, seven significantly, including rectal temperature, hemostatic agents, external hemostatic modalities, in-line stabilization, measurement and application of a cervical collar, football and other equipment removal. ATs should aim to incorporate emergency management review into continuing education choices.

Evaluating Quadrupedal Locomotion In Bats: A Geometric Morphometric Comparison Of Vertebral Adaptations Across Mammals, Jessica Upham

Electronic Theses and Dissertations

Flight is the primary locomotion of bats, while quadrupedal locomotion is not often observed and is widely variable among bats. Frugivorous bats in Pteropodidae are more efficient climbers than frugivorous bats in Phyllostomidae and insectivorous bats in Vespertilionidae, while phyllostomids and vespertilionids are better at walking on horizontal surfaces. The aim of this study is to investigate whether bats with differing modes of nonflight locomotion also exhibit disparity in thoracolumbar vertebral morphology. Using geometric morphometrics, we compared the thoracolumbar vertebral shapes of these bat families with other terrestrial and arboreal mammals. The results revealed distinct vertebral shapes among bat families …

The Articularis Genu As A Surrogate For Structural Determinants Of Peri-Articular Myopenia In Osteoarthritis, Davis Martin, José A.Cruz Ayala, Mary C. Gatterer, Tara Soria, Ryan Schroeder, Vinod Dasa, Luis Marrero

School of Medicine Faculty Publications

The functional limitations associated with the painful stiffness of knee osteoarthritis (kOA) can affect the muscles of the knee, such as the quadriceps femoris (QF) and articularis genu (AG). The vastus medialis oblique (VMO) of the QF complex is particularly sensitive to kOA. The AG, which can be sampled during total knee arthroplasty (TKA) for kOA, can provide information about the condition of the QF when affected by patient-reported disuse, helping to identify indicators of muscle weakness in the synovial fluid. This study compares the structural and gene expression changes between the VMO and the AG collected from patients with …

The Influence Of Intrinsic Foot Muscles In Modulating Foot Shape Relative To Substrate And The Efficacy Of Different Strengthening Approaches, Luke R. Lotsis

Masters Theses, 2020-current

Cross-sloped surfaces create an asymmetrical substrate for foot contact, introducing a slip force within the transverse plane and a gravitational pull within the coronal plane that increases the tendency to topple downslope. To maintain stability, the foot must make structural adjustments across the hindfoot, midfoot, forefoot, and hallux. In chapter 1, I investigated how IFMs respond to varying substrate conditions and balance demands, providing insight into their functional role in maintaining stability and adapting foot structure in static and dynamic locomotor tasks. Twenty-four healthy adults participated in a series of dynamic walking trials on flat, cross-sloped and sandy substrates and …

Functional Electrical Stimulation For Foot Drop: A Narrative Review, Garrett R. Watson

Honors Thesis

Foot drop (FD) is a neuromuscular impairment that limits ankle dorsiflexion during walking. It often leads to unsafe gait patterns, increases the risk of falls, and reduces independence. Functional electrical stimulation (FES) has emerged as a promising rehabilitation tool that activates muscles or nerves to improve foot clearance and support motor recovery. Unlike passive devices such as ankle-foot orthoses, FES promotes active neuromuscular engagement and may foster long-term improvements through neuroplastic adaptation. This narrative review examines the causes and clinical consequences of FD and evaluates the role of FES in restoring functional mobility. Key topics include FES technologies, stimulation parameters, …

Establishing The Dose-Response Effect Of Myofascial Release On Muscle Physiology, Sanjana Davuluri, Seth Spicer, Tyler Pigott

Rowan-Virtua Research Day

Context: Osteopathic manipulative treatment (OMT) is often indicated for back pain due to its high tolerability and post-treatment improvement in patients’ self-reported pain and functionality. Specifically, myofascial release (MFR) has been found to yield a significant improvement in both symptoms and quality of life. Until recently, there has not been much data published about the quantifiable effect of MFR and other OMT modalities on muscle physiology, especially taking treatment dose and force into consideration. Therefore, quantifying the changes in muscle characteristics through myotonometry would greatly benefit the field of osteopathic medicine in order to create more personalized treatment plans …

The Relationship Between Running Cadence And Stress Fractures In Competitive Distance Runners, Jason A. Richwall

Rowan-Virtua Research Day

Running is one of the most popular sports and forms of exercise worldwide. Stress fractures are a common and potentially season-ending injury among competitive distance runners, with recurrence rates as high as 22%. Biomechanical factors, including running cadence, have been implicated in injury risk, but their precise role remains an area of active investigation. This literature review examines the relationship between cadence and stress fractures, drawing data from both observational and experimental studies. Observational studies suggest that low cadence and rearfoot striking are associated with increased risk of bone stress injuries. Experimental studies reinforce these findings, demonstrating that increased cadence …

The Use Of Intramedullary Screw For Fixation Of Distal Ulnar Fractures, Adam Lencer, John Pignataro, Justin Le, Joyce Daniel Suarez, Michael Rivlin

Rowan-Virtua Research Day

Background

Distal ulna fractures frequently accompany distal radius fractures but are often underappreciated in both clinical and research contexts. While conservative management is frequently employed, particularly following volar locking plate (VLP) fixation of the radius, certain indications, such as distal radioulnar joint (DRUJ) instability, comminution, or high-energy trauma, may necessitate surgical fixation. This study evaluates patient-reported outcomes among patients with distal radius fractures treated operatively, comparing those with and without concomitant distal ulna fractures, and further stratifying based on the method of ulna fixation.

Methods

This retrospective review included 477 patients treated operatively for distal radius fractures by a single …
