Clinical Practice in Athletic Training

The Athletic Training Milestones (AT Milestones) were developed as an evaluation tool to capture the breadth and depth of athletic training knowledge, skills, and behavior. However, it is unclear whether athletic training programs are implementing this tool or how they are implementing it to gauge the clinical progression of students or residents in athletic training. We aimed to explore the perceptions and use of the AT Milestones among educators in athletic training programs. We used a cross-sectional, web- based survey with open-ended questions to collect data from athletic training programs on if and how they implement the AT Milestones at …

Anterior Cruciate Ligament Hybrid Remnant Preservation Reconstruction Demonstrates Similar Outcomes As Traditional Reconstruction After 6 Months: A Randomized Control Trial, Joshua P. Castle, Eleftherios L. Halkias, Brittaney Pratt, Ashley Frei, Matthew A. Gasparro, Vasilios Moutzouros

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

Mitochondria As Causes Of And Therapeutic Targets In Chronic Post-Sepsis Skeletal Muscle Weakness, Meagan Scott Kingren

Theses and Dissertations--Pharmacology and Nutritional Sciences

Sepsis, or the organ damage that ensues after the body fails to properly contain a local infection, is the leading cause of in-patient hospitalization in the United States. Advances in critical care medicine over the last 20 years have enabled most sepsis patients to survive the life-threatening dysregulated immune response. However, a majority of survivors report chronic weakness and fatigue years after sepsis, and the cause of this weakness remains largely unknown. This dissertation work focused first on elucidating the major causes of post-sepsis muscle weakness (Aim 1). This aim involved a time-course study to determine when muscle weakness was …

Physician Assistant Capstones, 2020-current

Abstract:

Background: Carpal tunnel syndrome (CTS) is now one of the most common workplace injuries, with nearly 50% of patients eventually requiring CTS release surgery as a permanent solution. With a concern of a younger incidence of CTS developing in a technology dependent society, some patients may fear even a minimal loss of function. To our knowledge there has been no study comparing forearm grip strength before symptoms develop to grip strength after the procedure has been performed.

Objectives: The aim of this study was to determine if there was a significant change in strength of the flexor digitorum superficialis …

Effects Of Expiratory Muscle Strength Training On Oropharyngeal Swallow Physiology In Persons With Obstructive Sleep Apnea (Osa): A Pilot Study, Ankita Murlidhar Bhutada

Graduate Theses and Dissertations (2019 - present)

Obstructive sleep apnea (OSA) is characterized by frequent narrowing of the upper airway during sleep. The estimated prevalence of swallowing impairments (dysphagia) in OSA patients ranges up to 80% and comprises approximately 50% of the caseload of practicing speech-language pathologists in the United States. Despite the high prevalence of dysphagia, there is a paucity of evidence supporting behavioral intervention(s) for ameliorating swallowing impairments in OSA. This pilot study assessed oropharyngeal swallowing physiology in persons with OSA and the feasibility and acceptability of a behavioral dysphagia intervention that specifically targets upper airway musculature – Expiratory Muscle Strength Training (EMST). A total …

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 …

A Bisphosphonate With A Low Hydroxyapatite Binding Affinity Prevents Bone Loss In Mice After Ovariectomy And Reverses Rapidly With Treatment Cessation, Abigail A. Coffman, Jelena Basta-Pljakic, Rosa M. Guerra, Frank H. Ebetino, Mark W. Lundy, Robert J. Majeska, Mitchell B. Schaffler

Publications and Research

Bisphosphonates (BPs) are a mainstay of osteoporosis treatment; however, concerns about bone health based on oversuppression of remodeling remain. Long-term bone remodeling suppression adversely affects bone material properties with microdamage accumulation and reduced fracture toughness in animals and increases in matrix mineralization and atypical femur fractures in patients. Although a “drug holiday” from BPs to restore remodeling and improve bone quality seems reasonable, clinical BPs have long functional half-lives because of their high hydroxyapatite (HAP) binding affinities. This places a practical limit on the reversibility and effectiveness of a drug holiday. BPs with low HAP affinity and strong osteoclast inhibition …

Age And Sex Differences In Load-Induced Tibial Cortical Bone Surface Strain Maps, Alessandra Carriero, Behzad Javaheri, Neda Bassir Kazeruni, Andrew A. Pitsillides, Sandra J. Shefelbine

Publications and Research

Bone adapts its architecture to the applied load; however, it is still unclear how bone mechano-adaptation is coordinated and why potential for adaptation adjusts during the life course. Previous animal models have suggested strain as the mechanical stimulus for bone adaptation, but yet it is unknown how mouse cortical bone load-related strains vary with age and sex. In this study, full-field strain maps (at 1 N increments up to 12 N) on the bone surface were measured in young, adult, and old (aged 10, 22 weeks, and 20 months, respectively), male and female C57BL/6J mice with load applied using a …

Estimating Infant Hip Joint Moments Using A Novel Musculoskeletal Model, Yeram Lim, Victor Huayamave, Christine Walck, Erin Mannen, Safeer Siddicky

Publications

Musculoskeletal models offer a convenient method to non-invasively study human development, function, and pathologies. While adult musculoskeletal models have been extensively studied [1], infant populations have been widely underserved. However, understanding infant joint biomechanics during the first year of life is vital considering abnormal loads may be detrimental to growth and development. Joint moments from an infant musculoskeletal model could help assess pathologies such as developmental dysplasia of the hip (DDH). Previous computational studies involving infant biomechanics [2, 3] lacked the modeling of active muscle response which may affect musculoskeletal development [4]. As such, the purpose of this study is …

A Comparison Of Power Variables For Two Loading Methods In Weighted Vertical Jumps 2020, Jonathan Tanguay

Master's Theses

Training exercises to develop muscular strength and power, such as the weighted jump squat, commonly utilize barbells and dumbbells to increase resistance. Strength coaches often measure improvements in peak force, peak power, and rate of force development to determine effectiveness of a training program. The purpose of this study was to determine if equipment selection (barbells vs. dumbbells) affects peak force, peak power, and/or rate of force development in weighted jump squats. Thirteen physically active, college-aged males (age: 21.6 ± 2.0 years, height: 182.8 ± 9.7 cm, body mass: 87.2 ± 9.0 kg, lean mass: 72.3 ± 8.1 kg) performed …

Osteoblast-Derived Fgf9 Regulates Skeletal Homeostasis, Liping Wang, Theresa M. Roth, Marcia J. Abbott, Linh Ho, Lalita Wattanachanya, Robert A. Nissenson

Health Sciences and Kinesiology Faculty Articles

FGF9 has complex and important roles in skeletal development and repair. We have previously observed that Fgf9 expression in osteoblasts (OBs) is regulated by G protein signaling and therefore the present study was done to determine whether OB-derived FGF9 was important in skeletal homeostasis. To directly test this idea, we deleted functional expression of Fgf9 gene in OBs using a 2.3 kb collagen type I promoter-driven Cre transgenic mouse line (Fgf9^{OB −/−}). Both Fgf9 knockout (Fgf9^{OB −/−}) and the Fgf9 floxed littermates (Fgf9^fl/fl) mice were fully backcrossed and maintained in an FBV/N background. Three …

Il-15 Mediates Mitochondrial Activity Through A Ppar𝛿-Dependent-Ppar𝛼-Independent Mechanism In Skeletal Muscle Cells, Shantaé M. Thornton, James E. Krolopp, Marcia J. Abbott

Health Sciences and Kinesiology Faculty Articles

Molecular mediators of metabolic processes, to increase energy expenditure, have become a focus for therapies of obesity. The discovery of cytokines secreted from the skeletal muscle (SKM), termed “myokines,” has garnered attention due to their positive effects on metabolic processes. Interleukin-15 (IL-15) is a myokine that has numerous positive metabolic effects and is linked to the PPAR family of mitochondrial regulators. Here, we aimed to determine the importance of PPAR𝛼 and/or PPAR𝛿 as targets of IL-15 signaling. C2C12 SKM cells were differentiated for 6 days and treated every other day with IL-15 (100 ng/mL), a PPAR𝛼 inhibitor (GW-6471), a PPAR𝛿 …

Effects Of Pelvis Impact Angle And Hip Muscle Forces On Hip Fracture Risk During A Fall Using An Advanced Hip Impact Simulator, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures in older adults are caused by falls [1]. Whether a given fall will cause hip fracture depends on bone strength, and on the impact force and stress applied to the bone during impact [2]. Improved understanding is required on how peak bone stresses during a fall depend on the mechanics of a fall, and on the state of contraction at the moment of impact of the muscles spanning the hip. Recently, Choi et al showed that, for lateral impact to the hip, peak stresses decrease with increases in hip abductor muscle force [3]. In the …

Influence Of Pelvis Impact Angle During A Fall: On The Protective Benefit Of Hip Protectors, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures are due to falls [1]. Laboratory measures have shown that wearable hip protectors reduce impact forces to the proximal femur during a simulated sideways fall on the hip [2, 3]. However, clinical evidence suggests that hip fractures still occur when hip protectors are worn [4]. Furthermore, while falls in real life result in a variety of impact configurations, biomechanical tests to date have focused only on lateral impact to the pelvis. In the current study, we examined how the force reduction provided by wearable hip protectors is affected by pelvis impact configuration during simulated sideways …
