Occupational Therapy | Graduate Capstone Projects

Purpose: The purpose of this study was to develop and pilot a questionnaire examining the relationship between sensory defensiveness and coping strategies, as well as establish typical ratings for sensory defensiveness among the adult population. Methods: Through snowball sampling, 91 participants completed the Sensory Response Questionnaire containing 69 questions. Participants’ responses to questions concerning sensations and coping strategies in various situations indicated levels of sensory defensiveness. Levels of sensory defensiveness were determined by mean ratings: < 2 low sensory defensiveness (Low SD), 2-2.5 some sensory defensiveness (Some SD), > 2.5 moderate sensory defensiveness (Moderate SD). Discussion: Kinnealy et al. (1995), estimates that 15% of the population has some level of sensory defensiveness that ...

Effective Therapies And Nursing Approaches: Improving Cognition In Older Adult Stroke Patients, Selyna Baltazar

Nursing | Senior Theses

Background

Ischemic stroke occurs in thousands of older adults throughout the year. Due to the lack of oxygen entering the brain, many patients experience a decline in cognitive function due to ischemic stroke. Cognition is the ability to understand, learn, and remember information which is needed for completing daily tasks. Modern technology has allowed for patients to survive ischemic strokes but has yet to provide proper screening tools and methods for stroke-related cognitive impairment.

Objective

To investigate the best practices for identifying, treating, and caring for patients with a cognitive injury related to a stroke. A review of the research ...

Neuroanatomical Distribution Of Neurons Within The Hypothalamic Paraventricular Nucleus That Project To The Brainstem Rostral Ventrolateral Medulla, Nicolas Fuller

Undergraduate Honors Theses

The sympathetic nervous system is important in maintaining cardiovascular homeostasis. Elevated cardiovascular-related sympathetic activity can lead to neurogenic hypertension and a host of other serious cardiac-related abnormalities. The paraventricular nucleus (PVN) of the hypothalamus plays an important role in sympathetic cardiovascular regulation. Neurons from the PVN project to the rostral ventrolateral medulla (RVLM), which is the main brain stem sympathetic cardiovascular control center. While RVLM-projecting PVN neurons have been well characterized, the topographical organization within the PVN subnuclei is still not fully known. This neuroanatomical study aimed to map the topographical distribution of RVLM-projecting PVN neurons. Four different carboxylate FluoSphereTM ...

The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez

Thinking Matters Symposium

In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with ...

Parkinson's Disease And Exercise: Steps Into A Hopeful Future, Jacob Barker

Spring Showcase for Research and Creative Inquiry

In the world of medicine and disease interventions, exercise is too often underlooked as a viable form of treatment or complementary treatment to medication. This is especially true with Parkinson’s Disease, a disease that attacks the basal ganglia of the brain and impairs neuromuscular function. In my analysis, I read a perspective from a PD patient, Gerry Hill, who has struggled with the disease himself and how he used physical activity to aid in his battle with the disease for both physical and psychological aid. Additionally, I performed research to understand how exercise benefits function within the brain. Aerobic ...

Aneurysmal Subarachnoid Hemorrhage And Acute Subdural Hematoma, Neurosurgical And Endovascular Rescue. Case Report., José Omar Santellan Resident, José Ramón Aguilar Dr., Abraham Ibarra Dr., Ulises García Dr.

Archives of Neurosurgery

Introduction: Acute subdural hemorrhage (aSDH) in association with aneurismal subarachnoid hemorrhage (SAH) is a severe disease with an incidence of 0.5% to 7.9% of all SAH. Due to the rarity of aneurysmal aSDH, it remains difficult to define a comprehensive management protocol. In this case review, following the CARE guidelines, we show the hybrid management of this pathology to know the importance of using different types of neurosurgical treatments in case of two severe diseases in critical patients.

We present two patients who developed sudden onset cephalea and neurological impairment secondary to aneurysmal subarachnoid hemorrhage associated with acute ...

Physiological Effects Of Activity-Based Anorexia In Female Rats And An Overview Of Eating Disorders, Madelyn Uyemura

Regis University Student Publications

The aim of this thesis is to bring AN to the foreground of conversation both in a scientific and sociological framework. Nearly 40 million Americans suffer from anxiety disorders, which is characterized by the feeling of a loss of control. In some cases, another disorder called anorexia nervosa (AN) can codevelop. AN is characterized by a refusal, and inability, to maintain a healthy body weight. Some suffering from anxiety may restrict caloric intake and increase exercise to cope with stress. This results in extreme caloric deprivation. AN can be modeled in rats using an activity-based anorexia (ABA) method. In ...

Eagle Syndrome: Efficacies Of Medical And Surgical Treatments, Kirklin Mitchell

Capstone Showcase

Eagle Syndrome is a rare syndrome caused by elongation of the styloid process of the temporal bone or calcification of the stylohyoid ligament occurring in a very small percentage of the population that can cause a wide range of common symptoms, leading to it being often misdiagnosed. While there are no set standards for treating Eagle Syndrome, both pharmaceutical and surgical options exist. Pharmaceutical options are often ineffective in long term treatment so surgery is usually required for full symptom resolution. Transoral and Transcervical surgeries have similar efficacies but each come with important drawbacks when considering which type of surgery ...

Kinematic Assessment Of Turning And Walking Tasks Among Stroke Survivors By Employing Wearable Sensors And Pressure Platform, Masoud Abdollahi, Pranav Madhav Kuber, Christopher Hoang, Michael Shiraishi, Rahul Soangra, Ehsan Rashedi

Physical Therapy Faculty Articles and Research

Stroke survivors often experience reduced movement capabilities due to alterations in their neuromusculoskeletal systems. Modern sensor technologies and motion analyses can facilitate the determination of these changes. Our work aims to assess the potential of using wearable motion sensors to analyze the movement of stroke survivors and identifying the affected functions. We recruited 10 participants (5 stroke survivors, 5 healthy individuals) and conducted a controlled laboratory evaluation for two of the most common daily activities: turning and walking. Among the extracted kinematic parameters, range of trunk and sacrum lateral bending in turning were significantly larger in stroke survivors (p-value<0.02). However, no statistical difference in mean angular velocity and range of motion for trunk/sacrum/shank flexion-extension were obtained in the turning task. Our results also indicated that during walking, while there was no difference in swing time, double support portion of gait among the stroke group was significantly larger (p-value = 0.001). Outcomes of this investigation may help in designing new rehabilitation programs for stroke and other neurological disorders and/or in improving the efficacy of such programs.Clinical Relevance— This study may provide a better insight on the detailed functional differences between stroke survivors and healthy individuals which in turn could be used to develop a more efficient rehabilitation program for stroke community.

In-Season Concussion Symptom Reporting In Male And Female Collegiate Rugby Athletes, Emily E. Kieffer,, P. Gunnar Brolinson, Arthur C. Maerlender, Eric Smith, Steven Rowson

Center for Brain, Biology and Behavior: Papers & Publications

Symptom inventories are generally only collected after a suspected concussion, but regular in-season monitoring may allude to clinical symptoms associated with repetitive subconcussive impacts and potential undiagnosed concussions. Despite sex-specific differences in symptom presentation and outcome of concussion, no return-to-play protocol takes sex into account. The objective of this study was to monitor a cohort of contact-sport athletes and compare the frequency and severity of in-season concussion-like symptom reporting between sexes. Graded symptom checklists from 144 female and 104 male athlete-seasons were administered weekly to quantify the effect of subconcussive impacts on frequency and severity of in-season symptom reporting. In-season ...

Visuomotor Adaptation During Asymmetric Walking, Charles Napoli

Masters Theses

Necessary for effective ambulation, head stability affords optimal conditions for the perception of visual information during dynamic tasks. This maintenance of head-in-space equilibrium is achieved, in part, by the attenuation of the high frequency impact shock resulting from ground contact. While a great deal of experimentation has been done on the matter during steady state locomotion, little is known about how head stability or dynamic visual acuity is maintained during asymmetric walking.

In this study, fifteen participants were instructed to walk on a split-belt treadmill for ten minutes while verbally reporting the orientation of a randomized Landolt-C optotype that was ...

Multiple Sclerosis (MS) is an autoimmune, neuroinflammatory disorder that is characterized by the breakdown of myelinated axons in the Central and Peripheral Nervous Systems. It is a potentially debilitating autoimmune disease that affects almost 1 million people in the United States, and nearly 2.5 million people worldwide. The precise etiology of MS is still being researched, but much progress has been made towards understanding the molecular mechanisms and impactful ways to treat this disease. While there is still no cure, new treatment plans are constantly being orchestrated in effort to alleviate the burden that MS carries. Combination treatment plans ...

Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova

Dissertations, Theses, and Capstone Projects

Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after ...
