Effect Of A Core Conditioning Program On Lumbar Paraspinal Area, Asymmetry And Pain Score In Military Working Dogs With Lumbosacral Pain, Andrea Leigh Henderson

Masters Theses

Introduction: Lumbosacral pain and stenosis are common causes of retirement from duty for Military Working Dogs (MWDs). Working dogs that receive surgical management for this condition often have a poor prognosis for return to duty after recovery. Humans with chronic low back pain demonstrate paraspinal muscle asymmetry, pain and dysfunction that often improve in response to an exercise program. This study investigated whether dogs with mild lumbosacral pain have decreased lumbar paraspinal muscle area, symmetry, and density, as well as increased pain and dysfunction compared to control dogs. Additionally, response of pain and dysfunction to an exercise program was assessed. …

Social Support In An Internet-Based Weight Loss Intervention Among College Students, Yijia Zhang

Masters Theses

Objective: To assess college students’ perceptions regarding online social support in an 8-week Internet-based weight loss intervention.

Participants: Participants were those randomized to the intervention group of an online weight loss intervention targeting overweight and obese college students.

Methods: Members of the intervention group had access to a private discussion forum and weekly live chat sessions, allowing for anonymous interactions. Following the 8-week intervention, intervention group members were invited to complete an online focus group, discussing these tools. The transcripts were directly copied from the live chat conversation history. Using thematic analysis, perceptions regarding online social support were identified, coded …

Attention, Hyperactivity, And Cognitive Performance In Adults With Attention-Deficit/Hyperactivity Disorder (Adhd), Brianna Elizabeth Pollock

Masters Theses

The extent to which Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms (i.e., inattention, hyperactivity/impulsivity) are associated with ADHD-related cognitive impairments has yet to be understood. This study sought to examine between-group differences in activity level, performance on a sustained attention task and objectively measured attention, while controlling for anxiety and depression severity in a sample of adults with and without ADHD (N = 26). High precision actigraphs and behavioral codes of visual attention to task were used to examine the extent to which activity level and visual attention to task are related to performance on a sustained attention task (i.e., Continuous Performance …

Differentiation Of Equine Mesenchymal Stromal Cells Into Cells Of Neural Lineage And Their Application Into A Novel Model For Acute Peripheral Nerve Injury In The Horse, Claudia Cruz

Masters Theses

Studies have shown that mesenchymal stromal cells (MSCs) are able to differentiate into extra-mesodermal lineages, including neurons. Positive outcomes were obtained after transplantation of neurally-induced MSCs in rats, rabbits and guinea pigs after nerve injury, but the effect of these cells is unknown in horses. Our objective was to test the ability of equine mesenchymal stromal cells to differentiate into cells of neuronal lineage, and to assess differences, if any, in morphology and protein expression. Additionally, we wanted to investigate if horse age and cell passage number contributed to the ability to achieve neural differentiation.

The first part of this …

Effects Of Cycling Workload And Cadence On Frontal Plane Knee Load, Ying Fang

Masters Theses

The effect of workload and cadence on sagittal plane knee biomechanics in cycling has been widely studied, however few studies have focused on the frontal plane. Frontal plane knee biomechanics, especially knee abduction moment, is closely related to the severity and progression of knee osteoarthritis. The purpose of this study was to investigate the effects of different workloads and cadences on knee frontal plane kinematics and kinetics. Eighteen subjects participated in this study. A motion analysis system was used to collect five cycles of kinematics during two minutes of cycling in eight testing conditions, which included five workload conditions of …

Accuracy Of Sensewear Armband Mini-Fly For Estimating Energy Expenditure In Normal Weight, Overweight, And Obese Individuals, Bethany Maryalice Forseth

Masters Theses

Obesity has become one of the greatest public health issues in America. BodyMedia promotes their SenseWear Armband physical activity monitor as a way to help with weight management. Purpose: to assess the accuracy of the SenseWear Armband Mini-Fly (SWA-MF) in adults of different BMI categories during rest, recovery, and two walking speeds. Methods: Forty-six participants were assigned to one of three BMI classifications: normal weight (n =15; 18.5-24.9 kg^.m^-2 [kilograms per meter squared]), overweight (n=17; 25-29.9 kg^.m^-2), or obese (n= 14; ≥30 kg^.m^-2). Height and weight were measured. Participants …

The Energy Expenditure And Feasibility Of Two Prenatal Yoga Programs, Doree Lynn Gardner

Masters Theses

Purpose: To determine the energy expenditure and feasibility of two different DVD-­‐ based prenatal yoga programs (static yoga practice and vinyasa practice). Methods: Participants were 25 women in their second trimester (13-­‐28 weeks) who werescreened for pregnancy-­‐related risk factors. The two DVDs used were “Prenatal Yoga with Shiva Rea” (DVD A) which is a static yoga practice, and “Jennifer Wolfes Prenatal Vinyasa Yoga” (DVD B) which is a flow yoga practice. Both DVDs were approximately 50-­‐55 minutes, and included three phases (warm up, main, cool down). Each subject completed both prenatal DVD routines approximately two weeks apart. The …

Joint Reaction Force And Contributions Of Surrounding Muscles To Knee Joint Load During Stair Ascent In Total Knee Replacement Patients And Healthy Individuals, Robert Jacob Rasnick

Masters Theses

Total knee replacement (TKR) is commonly used to correct end stage knee osteoarthritis (OA) of the knee joint. Unfortunately, difficulty with stair climbing has been seen to exist, prolonging the challenges of TKR patents. Complete understanding of loading at the knee is of great interest in order to aid patient populations, implant manufacturers, rehabilitation, and future research. The outcome of a TKR is intended to reestablish normal motion and loading of the knee. Musculoskeletal modeling provides a means to accurately approximate joint loading and the corresponding muscle contributions during a movement.

The purpose of the present study was to examine …

College Environment Behavioral And Perceptions Survey (Cebps): Using In-Depth Interviews As A Validation Method For Survey Development, Mackenzie Rae Ruppert

Masters Theses

Background: Although there are some validation procedures based in qualitative approaches (e.g. asking what someone thinks about the structure of a survey question during face, content validation, or cognitive interviews), there are no approaches to validate a subject’s responses by a “gold standard assessment”. The purpose of this study was to use a mix-methodology approach to validate subjects’ perceptions, which used indepth interviews as a criterion-based validation method.

Methods: 30 participants (15 male and 15 female) completed the CEBPS survey and an indepth interview with questions mirroring those in the survey. A priori coding was used to develop …

Biological Variation Of Thromboelastography Variables In Ten Healthy Female Horses, Jennifer Lee Scruggs

Masters Theses

Biological variability (BV) has important applications in laboratory medicine. It can be a source of variation in measured analyte values and provide guidance on reference interval use. BV has three components: between-individual variation (CVg), caused by differences in mean values of a particular analyte among members of a group, within-individual variation (CVi), caused by fluctuations around an individual’s inherent homeostatic set point, and analytical variation (CVa). Thromboelastography (TEG), a type of viscoelastic coagulation analysis, is becoming increasingly common in veterinary referral centers. Despite increased popularity, the optimal method of results interpretation is not clear. While population-based reference intervals (PRI) are …
