The Clinical Usefulness Of Vector Coding Variability In Female Runners With And Without Patellofemoral Pain, Tommy Joseph Cunningham
Theses and Dissertations--Kinesiology and Health Promotion
It has been suggested that Patellofemoral Pain (PFP) may be the result of a coordinate state which exhibits less joint coordination variability. The ability to relate joint coordination variability to PFP pathology could have many clinical uses; however, evidence to support clinical application is lacking. Vector coding’s coupling angle variability (CAV) has been introduced as a possible analysis method to quantify joint coordination variability. The purpose of this study was to assess the clinical usefulness of CAV measures from a dynamical systems perspective. This involved establishing the precision limits of CAV measures when physiological conditions are held constant, altering control …

Generalized Linear Latent Mixed Modeling Of Functional Independent Measures And Patient Outcomes, Maduranga Kasun Dassanayake
Open Access Theses & Dissertations
The Functional Independent Measure (FIM) is one of the most widely accepted functional assessment measures used in the rehabilitation community. Past research studies have investigated the relationship between place of discharge, admission FIM scores or FIM difference scores, and patients' characteristics and found relationships between those variables. However, most of these studies fail to account for the multi-layered multidimensionality of the FIM and the measurement error associated with the FIM items. This study utilizes Generalized Linear Latent Mixed Models (GLLAMM) and Structural Equation Models (SEM) to assess which patient characteristics are associated with FIM difference scores and the structural relationship …

Discrimination And Aggregative Patterns Among And Between Populations Of Entamoeba Spp., Katelyn M. Higgins
Honors Senior Capstones and Theses
Kin recognition facilitates the evolution of cooperation in animals, but its relevance in microorganisms and their behavior toward relatives remains unclear. The Entamoeba lineage constitutes an ideal model to determine the behavioral and signaling cues needed for aggregative preference. Chemical cues have been reported for E. histolytica but not E. dispar, suggesting cell-communication between con-specifics and behavioral differences with relevance for disease. Entamoeba varieties have been reported as ‘morphologically undistinguishable’. Two strains of E. invadens have been isolated from different hosts (VK-1: NS - Varanus komodoensis and IP1- serpentes) but were classified within the same ‘species’. Trophozoites …

The Effects Of Whole Body Vibration On Dorsiflexion In Chronic Ankle Instability, Lesley Abigail Thalman
Theses and Dissertations
BACKGROUND: Whole body vibration (WBV) platforms are currently used as adjunctive training devices for exercise programs, and have been shown to facilitate flexibility. One of the biggest contributing factors to chronic ankle instability (CAI) is the lack of dorsiflexion after lateral ankle sprains and WBV may be an effective way to increase range of motion in this population. PURPOSE: Determine if WBV done concurrently with static stretching (SS) is more effective then SS alone in improving dorsiflexion ROM in subjects with CAI. METHODS: Subjects were divided into 3 groups (control, static stretch, and static stretch and vibrate). Subjects stretched 4 …

Skeletal Muscle Function, Morphology, And Biochemistry In Ts65dn Mice: A Model Of Down Syndrome, Patrick Michael Cowley
Exercise Science - Dissertations
A common clinical observation of persons with Down syndrome at all developmental stages is hypotonia and generalized muscle weakness. The cause of muscle weakness in Down syndrome is not known and there is an immediate need to establish an acceptable animal model to explore the muscle dysfunction that is widely reported in the human population. Using a combination of functional, histological, and biochemical analyses this dissertation provides the initial characterization of skeletal muscle from the Ts65Dn mouse, a model of Down syndrome. The experiments revealed that Ts65Dn muscle over-expresses SOD1 protein but this did not lead to oxidative stress. Ts65Dn …
