Predicting The Progression Of Diabetes Mellitus Using Dynamic Plantar Pressure Parameters, Mathew Sunil Varre

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Diabetic peripheral neuropathy is one of the common complications of type-2 diabetes mellitus (DM). Changes in the intrinsic plantar tissue coupled with repetitive mechanical loads and loss of sensation may lead to foot related complications (skin break down, ulcerations, and amputations) in persons with neuropathy if left untreated. The purpose of this dissertation was to stratify individuals with pre-diabetes, diabetes with and without neuropathy using dynamic plantar pressure parameters during walking, using machine learning algorithms.Methods: Plantar pressure data was collected from one hundred participants during walking with pressure measuring insoles fixed between the feet and thin socks. Simultaneously high-definition …

The Effects Of An Acute Bout Of Exercise On Hunger Hormones In Individuals At Risk For Type 2 Diabetes, Sydney Spoon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Hunger hormone levels are typically dysregulated in obese and diabetic

populations, however; postprandial exercise has been shown to influence hunger hormone levels. Purpose: To determine if hunger hormones including acylated ghrelin and GLP-1 levels are altered in response to an acute bout (15 minutes) of walking in individuals at risk for type 2 diabetes mellitus (T2DM).

Methods: Ten subjects at risk for prediabetes (fasting blood glucose 100–125mg/dL) participated in this randomized crossover design trial. Subjects arrived at the laboratory following an overnight fast and underwent one of two conditions: 1) Test meal with no walking (CON) or 2) Test …

Comparing Functional Motor Control And Gait Parameters In Children With Autism To Those Of Age-Matched Peers Who Are Typically Developing, Patricia Stevenson, Samantha Novotny, Jillian May, Christopher Ancell

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to compare motor performance of children with Autism Spectrum Disorder (ASD) to that of age-matched peers who are typically developing (TD) on motor control tasks plus symmetry and variability of gait parameters across four walking conditions. A sample of convenience of children with ASD (n=6) and peers who are TD (n=6) were recruited. Motor control was assessed using initiation and completion times on the Timed Up and Go (TUG) test. Gait parameters were collected using a computerized walkway under four trial conditions: 1) walking at self-selected velocity (SSV); 2) walking during a tray-carrying task …

A Comparative Evaluation Of The Effects Of Incline On Kinematics And Muscle Function During Backward Walking, Daniel Brent Jensen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to investigate lower extremity kinematics and muscle activation patterns in inclined backward walking (IBW) versus traditional backward walking (BW). This purpose was achieved by evaluating performance of individuals walking backward on a treadmill at inclines of 0%, 6%, 8%, 10%, and 12%. Eleven participants (24.9 ± 4.8 yrs, 71.9 ± 11.6 kg, 1.7 ± 0.09m) recruited from the UNLV student body went through a familiarization training program before any data were collected. The familiarization training, which took place across 3 different days, served to: 1) help the participants become comfortable and familiar with BW …

Biomechanical Comparison Of A Rounded Outsole Shoe And Traditional Outsole Shoe, Sarah Horsch

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of the study was to determine the effects of shoe outsole design on maximum vertical acceleration and select kinematic parameters during level and uphill walking across phases of stance. Twelve participants, 7 males (75.1±9.3 kg, 173.6±3.6 cm, 22.9±3.5 yrs) and 5 females (56.5±5.1 kg, 158.3±4.5 cm, 25.4±11.1 yrs) granted written consent and preferred walking speed was determined. An accelerometer (480 Hz) was attached to the distal leg to measure maximum leg acceleration (Aleg) and an electrogoniometer (480 Hz) was placed on the back to measure sagittal lumbar motion (LumbarROM). Sagittal video capture (60 Hz) included thigh range of …
