The Effects Of A Yoga Intervention On Cognitive Function In Older Adults, Elizabeth Edwards May 2019

The Effects Of A Yoga Intervention On Cognitive Function In Older Adults, Elizabeth Edwards

All Graduate Plan B and other Reports

Cognitive decline and reduced cognitive function presents a serious risk to the older adult population. As the population of individuals over the age of 65 continues to increase, this presents a need for effective solutions to help people sustain healthy, independent lifestyles. Currently, physical activity is recommended for physical health in older adults and has shown evidence in maintaining cognitive function. In particular, the mind-body practice of yoga is a promising form of physical exercise that shows positive cognitive benefits. While the effects of yoga appear to be promising, the current literature is lacking scientific rigor. This study investigated the ...

Are Age-Related Changes In Perceptual-Motor Regulation Related To An Increased Falls Risk?, Steven Van Andel Dec 2018

Are Age-Related Changes In Perceptual-Motor Regulation Related To An Increased Falls Risk?, Steven Van Andel

Theses

Introduction

Decades of research have shown that approximately one in three older adults, aged 65 years or older, falls at least once each year (Campbell et al., 1990; World Health Organization, 2007). This is a problem in our ageing society; as the number of people in this aged cohort continues to increase, leading to an expected increase of falls and falls related medical costs in the coming years (Hendrie, Hall, Arena, & Legge, 2004). The consequences of falling are not only severe in terms of medical costs, for older adults a fall means injuries, decreases in quality of life and could even lead to death (Burns, Stevens, & Lee, 2016).

The current thesis adopts an ecological approach to investigate opportunities for falls prevention. According to an ecological approach, guidance of action is mediated by the perception of ‘opportunities for action’ or ‘affordances’ (Gibson, 1979). These affordances are always action scaled; a person perceives possibilities for action in relation to his or her own action system. For instance, a curb might afford ‘stepping onto’ for me, as I have sufficient ...

The Effect Of A Combined Multiple-Modality Exercise Intervention On Sensorimotor Function In Community Dwelling Older Adults, With A Subjective Cognitive Complaint: The M4 Study (Multi-Modal; Mind Motor), Sam Titheridge

Electronic Thesis and Dissertation Repository

Aging is associated with the increased onset of diseases such as cognitive impairment, and ultimately dementia. Participants, 55+ years, with a self-reported cognitive complaint completed a 6-month exercise intervention. They were randomized to either a multiple modality exercise program (M2), consisting of aerobic, stretching and balancing exercises or a multiple modality plus mind motor program (M4), whereby a square stepping exercise was incorporated. Participants were assessed for reaction time (RT), movement time (MT) and % errors at baseline and at 6-months using an eye tracking 1000 system. Participants performed prosaccades and antisaccades (AS). AS RT was significantly quicker from baseline – 6-months ...


Examining The Role Of Attention In Steering Using A Dual Task Paradigm, Venkata Naga Pradeep Ambati Jan 2014

Examining The Role Of Attention In Steering Using A Dual Task Paradigm, Venkata Naga Pradeep Ambati

Open Access Theses & Dissertations

Changing the direction of locomotion, often referred to as "steering", is an integral component of human locomotion. Steering requires maintaining dynamic balance while translating and rotating the body in the new travel direction. Given the level of sensation thought to be involved in sub serving goal directed modifications in steering, it is highly likely that steering control may require attention. Since attention resources decline with increasing age, we may see the influence of age on steering performance when attention resources are limited. Therefore, this study sought to investigate the role of attention in steering using a dual task paradigm in ...

Engagement Of Seniors: 'How' And 'Why' Engagement Profiles Change Over Time, Kelly Carr Jan 2014

Engagement Of Seniors: 'How' And 'Why' Engagement Profiles Change Over Time, Kelly Carr

Electronic Theses and Dissertations

This study explored 'how' and 'why' engagement profiles change throughout older adulthood within a framework of successful aging. A convergent parallel mixed methods design was employed. Fifty-four participants (mean age = 79.17, age range = 65-97 years; 21 males, 33 females) completed questionnaires to quantify 'past' and 'present' engagement. Focus groups segmented by decade of life and semi-structured interviews were completed with a subsample of participants (n = 42). Results indicated that participation in productive and active leisure activities decreased with increasing age, while social and passive leisure engagement remained stable. This change in engagement pattern may be a function of the ...

Promoting Older Adult Wellness Through An Intergenerational Physical Activity Exergaming Program, Kara Anne Strand Jan 2012

Promoting Older Adult Wellness Through An Intergenerational Physical Activity Exergaming Program, Kara Anne Strand

Graduate Theses and Dissertations

Background. The older adult population has been on the rise since the 1900s and is projected to increase to 72.1 million people by 2030 (Administration on Aging, 2011). Today's older adults suffer from chronic diseases that are preventable with regular physical activity. Although physical activity has been shown to prevent or improve chronic diseases as well as improve physical fitness, balance, strength, flexibility, and overall quality of life, fewer than five percent of older adults are meeting the current recommendation for physical activity. Additionally, rural-residing older adults are half as likely to participate in physical activity as urban-residing ...


Physical Activity Assessment Under Free-Living Conditions Using Pattern-Recognition Monitors, Miguel Andres Calabro Jan 2011

Physical Activity Assessment Under Free-Living Conditions Using Pattern-Recognition Monitors, Miguel Andres Calabro

Graduate Theses and Dissertations

Extensive literature has documented the health benefits of physical activity. Valid, reliable and feasible physical activity assessment tools are necessary to assess the complexity and multidimensionality of physical activity behavior. Pattern-recognition activity monitors that integrate information from multiple sensors appear to be the most promising approach for assessing physical activity under free-living conditions. Previous studies have provided support to the validity of pattern-recognition monitors for assessing the energy cost of activity under-free living conditions in young adults. However, children and older adults present unique measurement challenges for the assessment of physical activity under free-living conditions. The series of studies in ...

Graduate Theses and Dissertations

Introduction: By the middle of this century, the number of people of age 65 and over will more than double to 80 million (US census bureau, 1993). As more and more older people are getting added to the population, it becomes vital to understand the mechanisms and processes which can play a crucial role in their overall well being. The goal of the present study was to study the benefits of a novel method of training which can be an alternative to high intensity training and also be equally beneficial without the risks of heavy training in older adults. It ...


A Comparison Of Fall-Related Psychological Measures In A Community-Based Setting, Delilah Susanne Moore Jan 2008

A Comparison Of Fall-Related Psychological Measures In A Community-Based Setting, Delilah Susanne Moore

LSU Doctoral Dissertations

Falls and the fall-related psychological concerns associated with these events pose a serious public health problem among aging adults. Fall-related psychological instruments can be useful in quantifying important endpoints for fall prevention programs (Jorstad et al., 2005), yet no research currently exists to justify the use of these psychological instruments in a community-based falls risk screening. Therefore, the purpose of this dissertation was to examine the psychometric properties of several fall-related psychological measures in a falls risk screening context by: (a) examining the reliability and validity of the Falls Efficacy Scale-International (FES-I), Activities-specific Balance Confidence (ABC), modified Survey of Activities ...

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi Jan 2003

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi

LSU Master's Theses

Age is associated with deterioration in physical function (PF) and health-related quality of life (HRQL). Recent investigations suggest that a decrease in function may have a greater impact on perceived activities of daily living (ADL) competency in women than in men. The purpose of this investigation was to test the hypothesis that the association between PF and HRQL among older adults is influenced by gender. We examined 108 older adults aged 60 years or older, for PF (Continuous Scale-Physical Function Performance test (CS-PFP10) and Functional Status Index (FSI)) and HRQL (SF-36). In order to address this question we assigned subjects ...


A Comparison Of Self-Report And Performance-Based Measures Of Physical Function In Older Adults, Amy Elizabeth Dunbar Jan 2002

A Comparison Of Self-Report And Performance-Based Measures Of Physical Function In Older Adults, Amy Elizabeth Dunbar

LSU Master's Theses

The purpose of this thesis was to examine the associations between perceived quality of life (QOL)and self-report and performance-based measures of function. An additional purpose of this thesis was to determine whether the afore-mentioned tests could differentiate between independent-living and assisted-living older adults. A total of 36 residents, independent-living (n=22) and assisted-living (n=14), of a continuing care retirement community (age range=65-94) completed the study. Perceived QOL was assessed using the SF-36 and Nottingham Health Profile. The Barthel Index and Functional Status Index (FSI) were used to assess Activities of Daily Living (ADLs). Physical function was measured ...
