A Protocol Paper On The Preservation Of Identity: Understanding The Technology Adoption Patterns Of Older Adults With Age-Related Vision Loss (Arvl), Colleen E. Mcgrath

Occupational Therapy Publications

There are a growing number of older adults with age-related vision loss (ARVL) for whom technology holds promise in supporting their engagement in daily activities. Despite the growing presence of technologies intended to support older adults with ARVL, there remains high rates of abandonment. This phenomenon of technology abandonment may be partly explained by the concept of self-image, meaning that older adults with ARVL avoid the use of particular technologies due to an underlying fear that use of such technologies may mark them as objects of pity, ridicule, and/or stigmatization. In response to this, the proposed study aims to understand …

© Verbruggen et al. Response inhibition is essential for navigating everyday life. Its derailment is considered integral to numerous neurological and psychiatric disorders, and more generally, to a wide range of behavioral and health problems. Response-inhibition efficiency furthermore correlates with treatment outcome in some of these conditions. The stop-signal task is an essential tool to determine how quickly response inhibition is implemented. Despite its apparent simplicity, there are many features (ranging from task design to data analysis) that vary across studies in ways that can easily compromise the validity of the obtained results. Our goal is to facilitate a more …

Rethinking Interhemispheric Imbalance As A Target For Stroke Neurorehabilitation, Jing Xu, Meret Branscheidt, Heidi Schambra, Levke Steiner, Mario Widmer, Jörn Diedrichsen, Jeff Goldsmith, Martin Lindquist, Tomoko Kitago, Andreas R. Luft, John W. Krakauer, Pablo A. Celnik, Nathan Kim, Michelle D. Harran, Benjamin Hertler, Juan C. Cortes

Brain and Mind Institute Researchers' Publications

© 2019 American Neurological Association Objective: Patients with chronic stroke have been shown to have failure to release interhemispheric inhibition (IHI) from the intact to the damaged hemisphere before movement execution (premovement IHI). This inhibitory imbalance was found to correlate with poor motor performance in the chronic stage after stroke and has since become a target for therapeutic interventions. The logic of this approach, however, implies that abnormal premovement IHI is causal to poor behavioral outcome and should therefore be present early after stroke when motor impairment is at its worst. To test this idea, in a longitudinal study, we …

Spinal Stretch Reflexes Support Efficient Hand Control, Jeffrey Weiler, Paul L. Gribble, J. Andrew Pruszynski

Brain and Mind Institute Researchers' Publications

© 2019, The Author(s), under exclusive licence to Springer Nature America, Inc. Motor behaviour is most efficiently controlled by correcting only disturbances that influence task success. It is currently thought that such control is computed within a transcortical feedback pathway. Here we show that, for postural hand control, even the fastest spinal feedback pathway can produce efficient corrective responses, forcing a re-evaluation of how the nervous system derives the control laws that support motor behavior.

Intensive Balance Training For Adults With Incomplete Spinal Cord Injuries: Protocol For An Assessor-Blinded Randomized Clinical Trial., Janelle Unger, Katherine Chan, Carol Y Scovil, B Catharine Craven, Avril Mansfield, Kei Masani, Kristin E Musselman

Physical Therapy Publications

BACKGROUND: Impaired reactive balance control can lead to increased falls in people with neurological impairments. Perturbation-based balance training (PBT), which involves repetitive exposure to destabilizing external perturbations, improves the ability to take reactive steps in older adults and individuals who have had a stroke.

OBJECTIVE: The objective is to investigate whether PBT or conventional intensive balance training (CIBT) results in greater improvements in reactive stepping ability in individuals with chronic incomplete spinal cord injury (iSCI).

DESIGN: The design consists of an assessor-blind randomized clinical trial comparing the efficacy of 2 balance training programs (PBT and CIBT) matched for training duration …

Dual Therapy Treatment Of Pediatric Acute Lymphoblastic Leukemia With Blinotumomab And A Standard Chemotherapy Regimen, Tori I. Scheffler

Selected Honors Theses

Leukemia is the number one cancer affecting children in the nation, with acute lymphoblastic leukemia being the most prevalent classification.1 While new and innovative treatment protocols have greatly increased the success rate of primary cancer patients, those who face relapse receive a much more dismal prognosis. Recent studies have shown that patients who relapse quite frequently have developed drug-resistant clones of the original cancer cells, leading to a need for various secondary treatment options. The drug-resistance is due to clonal mutations that take place within the cancer cell, most often because of an outside pressure or stress within the environment …

The immune system encompasses acquired and innate immunity that matures through interaction with microenvironmental components. Cytokines serve as environmental factors that foster functional maturation of immune cells. Although NOD/SCID/IL2rgKO (NSG) humanized mice support investigation of human immunity in vivo, a species barrier between human immune cells and the mouse microenvironment limits human acquired as well as innate immune function. To study the roles of human cytokines in human acquired and innate immune cell development, we created NSG mice expressing hIL-7 and hIL-15. Although hIL-7 alone was not sufficient for supporting human NK cell development in vivo, increased frequencies of human …

Recent years have seen advances in our understanding of the neural circuits associated with trauma-related disorders, and the development of relevant assays for these behaviors in rodents. Although inherited factors are known to influence individual differences in risk for these disorders, it has been difficult to identify specific genes that moderate circuit functions to affect trauma-related behaviors. Here, we exploited robust inbred mouse strain differences in Pavlovian fear extinction to uncover quantitative trait loci (QTL) associated with this trait. We found these strain differences to be resistant to developmental cross-fostering and associated with anatomical variation in basolateral amygdala (BLA) perineuronal …

The Relationship Between Non-Suicidal Self-Injury, Suicide-Attempts And Resilience, Life Satisfaction, And Subjective Happiness In Minority Groups, Anna Siewers

Mahurin Honors College Capstone Experience/Thesis Projects

Non-suicidal self-injury and suicide ideation are important issues and known predictors of suicide attempts for any demographic, but specifically for minority groups who are significantly understudied and underreported in comparison to their White and Heterosexual counterparts. It has been found that among adolescents and college students, minority students are disproportionately impacted and are at greater risk for suicidal ideation and behavior. The goal of the present study was to examine the role of both ethnic and sexual minority experience in NSSI and suicide attempts, as well as potential protective factors. A sample of 2,280 undergraduate students completed a survey assessing …

Women & Adhd Functional Impairments: Beyond The Obvious, Noelle Marita Lynn

Masters Theses

Women with Attention Deficit Hyperactivity Disorder are an understudied and underserved population. Research on women with ADHD has shown that they are significantly impaired by ADHD and its functional impairments. It also shows that women often internalize their symptoms and impairments. However, no research was found that explores what this internalization does to the women. The researcher chose to begin to address this gap in the literature through this qualitative phenomenological study. The purpose of this study is to explore the impact of functional impairments caused by ADHD on the internal lived experiences of women.

The researcher conducted fourteen interviews …
