Bending The Elbow During Shoulder Flexion Facilitates Greater Scapular Upward Rotation And A More Favorable Scapular Muscle Activation Pattern, Alon Rabin, Brakha R. Tabi, Timothy L. Uhl, Zvi Kozol

Physical Therapy Faculty Publications

Context: Decreased scapular upward rotation (UR) and diminished activation of the serratus anterior (SA) and lower trapezius (LT) are often observed among patients with subacromial impingement syndrome. Maintaining the elbow fully flexed during shoulder flexion may limit glenohumeral motion due to passive insufficiency of the triceps brachii and therefore facilitate greater scapular UR and increased scapular muscle activation. Objectives: To compare scapular UR, SA, upper trapezius (UT), middle trapezius, and LT activation levels between shoulder flexion with the elbow extended (Flexion-EE) to shoulder flexion with the elbow fully flexed (Flexion-EF). This study hypothesized that Flexion-EF would result in …


An Investigation Of Hhv6'S Impact On The Cognitive Progression And Microglial Changes In An Alzheimer's Disease Cohort, Charles E. Seaks Jan 2022

An Investigation Of Hhv6'S Impact On The Cognitive Progression And Microglial Changes In An Alzheimer's Disease Cohort, Charles E. Seaks

Theses and Dissertations--Physiology

The role of herpesviruses and, more specifically, HHV6 in the development of Alzheimer’s disease (AD) and associated cognitive decline is still being investigated. High ubiquity and prevalence in the population have led to a high degree of skepticism about HHV6 as a potential contributor to cognitive decline and dementias. However, recent evidence related to another herpesvirus, herpes simplex virus 1, suggests that reactivation, not carriage, of the virus may be the key factor to explain the dissonance between the virus’ ubiquity and contributions to dementias. With that in mind, we set out to assess cases from the Sanders-Brown Center on …

Autonomous Self-Care: A Means To Mitigate Secondary Traumatic Stress Among Clinical Social Workers, Jessica Byrd

DSW Capstone Projects

Secondary traumatic stress (STS) negatively impacts the health of clinical social workers, thus, impairing their ability to provide quality services. The symptoms and consequences of STS have been discussed for decades and the conversation continues because STS is a prevalent and pervasive problem that effects social workers, clients, and organizations. For as long as STS has been recognized as a problem, self-care has been identified as a solution. Yet, clinical social workers underutilize self-care strategies to safeguard their mental, physical, and emotional well-being.

A systematic review of the literature review was conducted to explore, why self-care is underutilized among clinical …


Transforming Hurt Boys Into Restored Men: The Lack Of Mental Health Treatment For Black Male Trauma Survivors, Shericka Danielle Smith Jan 2022

Transforming Hurt Boys Into Restored Men: The Lack Of Mental Health Treatment For Black Male Trauma Survivors, Shericka Danielle Smith

DSW Capstone Projects

Trauma affects individuals differently, but the prevalence of trauma and its impact on Black males is detrimental. Black males are at higher risk for posttraumatic stress disorder (PTSD), depression, substance abuse, and violent crimes when trauma is left untreated by a mental health professional. As the number of traumatic events experienced by Black males continues to rise, the number of these males who seek mental health treatment remains stagnant and painfully low. Many factors play into these behaviors, yet very little data exists on what is being done to change them.

Product one is a systematic literature review in which …

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Schools are reopening or have already reopened while implementing precautions intended to reduce the transmission of COVID-19. However, evidence on the effects of these strategies or their benefits relative to each other in the school environment is indirect or lacking. This study investigated the effects of some of these strategies as employed by Kentucky schools in the fall 2020 semester using a linear mixed effects regression model using publicly available fall 2020 school incidence data, survey data from school staff, and Kentucky Department of Education data on school faculty and primary enrollment.


Increasing Physical Activity Rates Among High School Girls In Jefferson County, Kentucky, Haley Copeland Jan 2022

Increasing Physical Activity Rates Among High School Girls In Jefferson County, Kentucky, Haley Copeland

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Obesity rates across the U.S. are increasing, especially among adolescent females. Physical activity rates have been associated with obesity and many related health outcomes. Regular physical activity can help adolescents improve their cardiorespiratory fitness, build strong bones, control their weight, and reduce depression 1. It can also help reduce the risk of developing health conditions like heart disease, cancer, high blood pressure, osteoporosis, type II diabetes, and obesity 1. Thus, physical activity among youth provides a risk factor to target, with the intention of eventually decreasing obesity rates.

Recommended physical education class CDC guidelines are not being met …

Social And Biological Determinants Of Pregnancy-Related Mortality And Morbidity In A Rural, Underserved Population, Anna Hansen

Theses and Dissertations--Sociology

Cases of severe maternal morbidity (SMM) and pregnancy-related mortality (PRM) are increasing in the US. Research concerning SMM and PRM has neglected women in Central Appalachia; a largely rural, health-disparate population. The aims of this study are two-fold: (1) Examine patient-level and place-based predictors of SMM/PRM via hierarchical logistic regression modeling, and (2) Elucidate Appalachian healthcare patients’ and providers’ experiences with SMM/PRM, perceptions of contributing factors, and insights on points of intervention.

This study uses a mixed methods approach guided by the WHO’s conceptual framework for action on social determinants of health to identify determinants of SMM and PRM among …


An Examination Of Three Transitional Events In The Substance Misuse Trajectories Of Women With Criminal Legal System Involvement, Martha Tillson Jan 2022

An Examination Of Three Transitional Events In The Substance Misuse Trajectories Of Women With Criminal Legal System Involvement, Martha Tillson

Theses and Dissertations--Sociology

Research has consistently demonstrated that criminal legal system (CLS)-involved women are distinct from men in initiation and course of drug use, with important differences on biological, environmental, and sociocultural levels. Thus, the unique pathways and transitions into and out of drug use for women with CLS involvement are critical to consider from a research perspective, but also from a need to develop and support evidence-based, women-centered services in correctional contexts. This dissertation project uses a three-paper format to investigate three aims: (1) to understand CLS-involved women’s initiations to injection drug use and their experiences providing injection initiation assistance (IIA) to …


Deletion Of Period Genes Exacerbates Diet-Induced Obesity In Female, But Not Male, Mice, Elizabeth Kantra Jan 2022

Deletion Of Period Genes Exacerbates Diet-Induced Obesity In Female, But Not Male, Mice, Elizabeth Kantra

Theses and Dissertations--Biology

Sex differences in obesity in mice are mediated by differential responses of circadian rhythms to high-fat feeding in males and females. Other studies also showed circadian Period genes regulate diet-induced obesity in mice. In this study, we investigated the role of the Period genes in regulating sex differences in obesity. Male and female C57BL/6J wild type, Per1/2 KO, and Per1/2/3 KO mice were housed in 12L:12D and fed high-fat diet for 12 weeks. We found a striking sex difference in obesity such that disabling the Period genes exacerbated adiposity in female, but not male, mice. Increased adiposity in female Period …
