The Effect Of One-On-One Intervention In Athletes With Multiple Risk Factors For Injury, Kathryn Schwartzkopf-Phifer Jan 2017

The Effect Of One-On-One Intervention In Athletes With Multiple Risk Factors For Injury, Kathryn Schwartzkopf-Phifer

Theses and Dissertations--Rehabilitation Sciences

Background: Lower extremity (LE) musculoskeletal injuries in soccer players are extremely common. These injuries can result in many days of lost time in competition, severely impacting players and their respective teams. Implementation of group injury prevention programs has gained popularity due to time and cost-effectiveness. Though participation in group injury prevention programs has been successful at reducing injuries, programs often target a single injury and all players do not benefit from participation. Players with a greater number of risk factors are most likely to sustain an injury, and unfortunately, less likely to benefit from a group injury prevention program. …

Social Participation In Schools: Developing The Role Of Occupational Therapy Practitioners, Kelly L. Leigers

Theses and Dissertations--Rehabilitation Sciences

The aim of this dissertation is to build the repertoire of occupational therapy practitioners so that they are better prepared in the provision of services addressing social participation of students with disabilities in the general education classroom. Students with disabilities in general education classrooms tend to have greater difficulty establishing and maintaining friendships (Wight & Chapparo, 2008), have fewer reciprocated friendships (Kemp & Carter, 2002), and lower stability in relationships than peers without disabilities. Furthermore, studies indicate that students with disabilities are less social accepted (Ekornas, Heimann, Tjus, Heyerdahl, & Lundervold, 2011) and are more isolated (Nadeau & Tessier, 2006). …


Prediction Of Acute And Recurrent Ankle Sprains In Athletes, Ryan S. Mccann Jan 2017

Prediction Of Acute And Recurrent Ankle Sprains In Athletes, Ryan S. Mccann

Theses and Dissertations--Rehabilitation Sciences

Ankle sprains are not only among the most common sport-related injuries, but also associated with a high rate of recurrence. While prevention is a favorable approach to reducing the incidence of index and recurrent ankle sprains, identifying individuals at greater risk may improve allocation of preventative resources. This dissertation aimed to accomplish the following through three aims: 1) determine the ability of baseline clinical tests to predict acute lateral ankle sprain (LAS) in an understudied athletic population, 2) describe the degree of residual impairments and activity limitations in athletes returning to play from a LAS, and 3) determine the ability …

Occupational Therapy Capstones

There is a growing population of older adults, or those people over 65 years old in long term care (LTC) facilities who report sleep deficiencies at a heightened rate, leading to decrease function, cognition, and social participation while increasing mortality, morbidity and the risk of falling (Booth & McMilliam, 2009; Cipolli, Mazzetti, & Plazzi, 2013; Crowley, 2011; Dzierewski et al., 2014; Helbig et al., 2013; Kuck, Pantke, & Flick, 2015). Occupational therapists (OTs) offer non-pharmacological sleep interventions in the long-term care facilities but are not present at many relevant sleeping times. This scholarly project is a flow chart aid to …


Female Veterans And Homelessness: A Resource Guide For Occupational Therapists, Jamie Schacht, Alison Tonsager Jan 2017

Female Veterans And Homelessness: A Resource Guide For Occupational Therapists, Jamie Schacht, Alison Tonsager

Occupational Therapy Capstones

Female veterans are the fastest growing subpopulation among the homeless population in the United States (U.S.) (Boothe, 2017). Female veterans report lack of access to gender-specific programs and therapy groups within the United States Department of Veterans Affairs (VA) to meet specific needs post-deployment (U.S. Department of Veterans Affairs, 2015b). Difficulty with reintegration post-deployment has been linked with homelessness among female veterans. There is evidence to support female veterans' over-representation in the homeless population is due to a higher prevalence of risk factors for homelessness as compared to male veterans and females within the general population (Byrne, Montgomery, & Dichter, …

Using Evidence To Address Psychosocial Impairments Post-Stroke: A Guide For Occupational Therapy, Michael Thurn, Emilee Rath

Occupational Therapy Capstones

Introduction: Following a stroke, individuals experience a wide variety of physical and psychosocial impairments. While physical impairments are commonly given attention by medical practitioners, psychosocial impairments are often overlooked or undiagnosed. (Hildebrand, 2015). Unfortunately, the same is true in occupational therapy, where physical and psychosocial issues have not been receiving the same amount of attention, physical issues being addressed far more than psychosocial issues (Gillen, 2014). The purpose of this scholarly project is to provide occupational therapists a guide to use of current evidence-based assessments and interventions to address psychosocial impairments following stroke. The guide focuses on evidence-based assessments, and …

The location of the therapy session was found to be a vital component among parent and occupational therapist interaction. Finally, this research …


Synthesis Of Multifunctional Polyacrylates And A Binding Group To Hemoglobin For The Treatment Of Traumatic Brain Injuries, Marina Michaud Jan 2017

Synthesis Of Multifunctional Polyacrylates And A Binding Group To Hemoglobin For The Treatment Of Traumatic Brain Injuries, Marina Michaud

Honors College Theses

Hemoglobin based oxygen carriers (HBOCs) hold promise as an effective emergency treatment of severe traumatic brain injuries (TBI). In the latest generation of HBOCs, polynitroxyl-pegylated hemoglobin (PNPH), cell-free hemoglobin is modified with TEMPO and PEG which reduce the toxicities associated with earlier generations of HBOCs. In our efforts to optimize the economic and therapeutic impacts of PNPH’s we have synthesized polydimethylaminoethyl methacrylate (poly-DMAEMA) under controlled living conditions via reverse addition-fragmentation chain transfer (RAFT) polymerization. The poly-DMAEMA was then successfully functionalized via quaternization of its NMe2 groups using chloroacetate derivatives of the TEMPO and PEG. This process was quantitative and …

Blow Fly (Diptera: Calliphoridae) Responses To Different Colors Of Baited Traps, Oluwadamilola Olufunso Oke

Honors College Theses

Blow flies (Diptera: Calliphoridae) are usually the first insects to colonize human remains. By determining the time of colonization, a postmortem interval (PMI), or “time of death”, can be estimated. To develop more accurate PMI estimates, it is important for forensic entomologists to understand the cues that Blow flies use to locate vertebrate remains. The purpose of this study was to determine whether Blow flies use visual cues, in addition to olfactory cues, to locate carrion. Two colors of fly traps, clear and green, were constructed and chicken gizzard used as bait. Three Blow fly species exhibited a significant preference …
