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 …

The Effect Of A Multiple Modality Mind-Motor Exercise Intervention On Single And Dual-Task Gait, Balance, And Executive Function, In Community Dwelling Older Adults With A Subjective Cognitive Complaint: A Randomized Controlled Trial., John P. Bocti

Electronic Thesis and Dissertation Repository

Cognitive decline disorders are becoming increasingly prevalent, with older adults at increased risk. Combined exercise has been recently explored as an intervention to help to prevent the decline, however cognitive activation in combination with physical activity has yet to be explored. Therefore, the purpose of the study is to determine the effects of multiple modality exercise programs in combination with a mind-motor task and their effects on mobility and cognitive variables. A total of (n=89) older adults (55+ yrs), with subjective cognitive complaints participated in a multiple modality exercise class, three days a week over six months, with the intervention …

Examining The Roles Of Life Satisfaction, Meaning In Life, And Daily Hassles In Predicting Suicide Ideation Among Community-Residing Older Adults, Orsolya Gyorgy

Electronic Thesis and Dissertation Repository

Research is needed testing models that potentially promote psychological well-being and reduce suicide risk in later life (Heisel, 2006). In the present study, we tested Shmotkin (2005) and Shrira’s (2011) theory proposing that subjective well-being and meaning in life serve unique as well as interrelated roles in promoting psychological functioning in the face of adversity. We specifically investigated whether life satisfaction and meaning in life are more strongly inter-correlated in the presence of daily hassles, and tested the premise that when either life satisfaction or meaning in life is low, the other variable is more strongly associated with suicide ideation, …

Exploring The Fall-Risk Experience Of Masters Athletes Actively Competing In Sport, Dylan Brennan

Electronic Thesis and Dissertation Repository

The risk of falling increases in adults over the age of 65. Exercise can prevent falls. The motivation to partake in physical activity might be dependent on an older adult’s experience with the risk of falling. Since the majority of older adults are sedentary, experiences of masters athletes can provide valuable insights. The purpose of this phenomenological study was to explore the fall-risk experience of masters athletes actively competing in sport. Masters athletes over the age of 55 (n=22) described their experiences in semi-structured interviews. Data was analyzed through an interpretive-constructive paradigm using inductive content analysis. There were five dominant …

Antihyperglycemic Medications And Hypoglycemia In Older Adults With Diabetes, Kristin K. Clemens

Electronic Thesis and Dissertation Repository

Background: In the last decade, several new antihyperglycemic medications have been approved to treat people with diabetes. However, the hypoglycemia risk of these medications in older adults in routine clinical practice remains unclear. Further, there is limited understanding as to how these medications are being prescribed to older adults in our region.

Methods: We carried out retrospective, population-based studies of adults age 66 and older in Ontario, Canada using linked healthcare databases. We first investigated the real-world hypoglycemia risk of 2 antihyperglycemic medications – glyburide and modified-release gliclazide. In an ecological study, we then examined trends in antihyperglycemic medication prescriptions, …

'I Am Not Disabled. It's My Environment That Makes Me Disabled': A Critical Ethnography Of Age-Related Vision Loss (Arvl) In Older Adulthood, Colleen E. Mcgrath

Electronic Thesis and Dissertation Repository

This thesis aims to deepen understandings of how various aspects of the environment shape how older adults with age-related vision loss (ARVL) negotiate and engage in occupation. The thesis further raises critical awareness of the ways in which environmental features, embedded in ageist and ableist assumptions, shape and perpetuate experiences of disability for older adults with ARVL. A critical ethnography was undertaken, informed by theoretical concepts drawn from critical gerontology, environmental gerontology, a critical occupational perspective, and critical disability theory. A total of ten older adults with ARVL participated in three data generation sessions consisting of a narrative interview, semi-structured …

Careful, Not Fearful: A Mixed Methods Study To Investigate Fall-Risk Appraisal And Fear Of Falling In Community-Dwelling Older Adults, P. Karen Simmavong

Electronic Thesis and Dissertation Repository

This study investigated older adult’s accuracy in fall-risk judgement and ascertained whether fall-risk appraisal was situation specific or general in nature. Convenience and snowball sampling were used to recruit 30 community-dwelling older adults aged 65 years and older. An embedded correlational mixed methods was utilized to investigate relative and absolute fall-risk judgement, balance confidence, and hazard identification. Using Pearson Product Moment correlations, multiple regressions, and qualitative analysis, the findings suggest older adults are not always accurate in appraising fall-risk. Judgements were specific and not general in nature, as only 9.30% of variance in risk appraisals and 12.96% of variance in …

The Relationship Between Dairy Product Consumption And Cognitive Performance In A Group Of Community-Dwelling Healthy Older Adults, Mariam R. Ismail

Electronic Thesis and Dissertation Repository

Dietary intake is one of the modifiable factors that may affect older adults’ cognitive function in their later years. Very little research has considered the potential role of dairy products on cognitive function. The aim of the present study was twofold: first, to investigate whether there is a difference in cognitive performance between older adults who consumed the recommended amount of dairy products (3 servings per day) and individuals who consumed less than the recommended amount (1 or 2 servings per day); second, to examine whether there is an association between the nutrients contained in the dairy products and cognitive …
