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 ...

Purpose

This study compared cognitive (attention, learning, and memory) and typing outcomes during slow treadmill walking or sitting. Seventy-five healthy individuals were randomly assigned to a treadmill walking group (n=37; 23 female) or sitting group (n=38; 17 female).

Methods

The treadmill walking group completed a series of tests while walking at 1.5 mph. The sitting group performed the same tests while sitting at a standard desk. Tests performed by both groups included: the Rey Auditory Verbal Learning Test and a modified version of the Paced Auditory Serial Attention Test. In addition, typing performance was evaluated.

Background

Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing. Simple walking models suggest that preemptive push-off reduces center-of-mass work, possibly reducing metabolic rate. Studies with bilateral exoskeletons have found that push-off beginning before leading leg contact minimizes metabolic rate, but timing was not varied independently from push-off work, and the effects of push-off timing on biomechanics were not measured. Most lower-limb amputations are unilateral, which could also affect optimal timing. The goal of this study was to vary the timing ...


Pre-Prandial Vinegar Ingestion Improves Two-Hour Glucose Control In Older, Type Ii Diabetics More Than Post-Prandial Walking, Sarah J. Taylor, Matthew J. Garver, Anna E. Ciufo, Taylor G. Flowers, Chase M. Harbach, Austin A. Ray, Cory M. Scheadler Feb 2015

Pre-Prandial Vinegar Ingestion Improves Two-Hour Glucose Control In Older, Type Ii Diabetics More Than Post-Prandial Walking, Sarah J. Taylor, Matthew J. Garver, Anna E. Ciufo, Taylor G. Flowers, Chase M. Harbach, Austin A. Ray, Cory M. Scheadler

International Journal of Exercise Science: Conference Proceedings

Background: Exercise engagement benefits diabetic patients through an insulin-like effect on muscle. Literature indicates that vinegar consumption may lower blood glucose levels. It is not currently clarified whether a relative amount of vinegar ingestion or a walking bout is more effective at controlling glucose in older, Type II diabetics during the acute phase following a meal. Purpose: The aim was to directly compare the impact of preferred-pace walking (15 min, postprandial) versus ingestion of a relative quantity of vinegar (0.3 g/kg) on two-hour glucose control. Methods: The two arms of the trial were completed in a randomized, crossover ...


Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev Jan 2015

Age-Associated Adaptations In Lower Limb Motor Patterns During Walking And Cycling, Harsh Harish Buddhadev

Graduate Theses and Dissertations

Muscular strength and power generating ability decline with advancing age. Older adults adapt their lower limb motor patterns to cope with these declines in muscle function. When mechanical demands approach limits of lower limb muscular capacity, motor patterns must be adapted to produce a desired movement. The term “motor pattern” is used to broadly represent the kinematic and kinetic profile of a person accomplishing a given task. Generally, these adaptations involve higher reliance on stronger proximal muscles to compensate for limitations or weakness of distal muscles. Three studies were conducted to examine factors affecting differences between older and young adults ...

Background: Physical inactivity is one of the leading risk factors for non-communicable diseases, yet many are not sufficiently active. The Physical Activity through Sustainable Transport Approaches (PASTA) study aims to better understand active mobility (walking and cycling for transport solely or in combination with public transport) as an innovative approach to integrate physical activity into individuals’ everyday lives. The PASTA study will collect data of multiple cities in a longitudinal cohort design to study correlates of active mobility, its effect on overall physical activity, crash risk and exposure to traffic-related air pollution. Methods/Design: A set of online questionnaires incorporating ...
