No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice
No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …
Effect Of Water Immersion And Jet Perturbation On Balance In Older And Younger Adults, Matthew Baldwin
Effect Of Water Immersion And Jet Perturbation On Balance In Older And Younger Adults, Matthew Baldwin
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Background: Although balance exercises are often performed in shallow pools, the efficacy of this practice is not well understood. Purpose: To quantify the effect of water depth and jet intensity on measures of balance in older and younger adults. Subjects: Sixteen older (age = 62.8 °” 9.56 yrs) and fifteen younger (age = 22.5 °” 1.85 yrs) adults. Methods: Posturography data were collected as participants stood quietly for 90 seconds on land and at various water depths and jet intensities. Results: Main effects < 0.001) and pairwise comparisons revealed that all measurements increased with increasing water depth and jet intensity,with older adults increasing statistically less than younger adults at higher jet intensities. Conclusions: Water immersion to the xiphoid process and water jet intensities at or above 40% seem to be environmental conditions that produce the greatest postural sway.
Test-Retest Reliability Of The Neurocom® Vsr™ Sport In Division I Collegiate Female Soccer Players, Crystal Davisson
Test-Retest Reliability Of The Neurocom® Vsr™ Sport In Division I Collegiate Female Soccer Players, Crystal Davisson
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The NeuroCom® VSR Sport stability evaluation test (SET) protocol was designed to identify postural control deficits in athletes who have sustained a concussion. The purpose of this study was to determine the test-retest reliability of the NeuroCom® VSR Sport SET protocol in non-concussed Division I collegiate female soccer players. A secondary purpose of this study was to determine whether participants displayed a learning effect when tested using the SET protocol across three days. A repeated measures design was used, testing participants on days 1, 7, and 8. Nineteen participants (20.05 ± 1.26 years old) from Utah State University’s women’s soccer …

Modern Technology And An Aging Population: Can The Use Of The Wii Fit Gaming System Improve Functional Balance In Community Dwelling Seniors?, Curtis N. Phillips
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Seniors are a growing segment of the population of the United States. By 2030 they will make up nearly 20% of the general population. Senior citizens face many health challenges as they age. Injury due to falling is a major concern for many in this age group. Research shows that approximately one third of seniors will fall each year. Injuries that result from falls have been identified as the number one cause of accidental death in this age group each year. While falls have been studied by researchers for a number of years, and some progress has been made in …
