The Role Of Occupational Therapy In The Recognition, Assessment, And Treatment Of Presbyvestibulopathy, Jennifer Hill, Ellen Hudgins, Sharon Leonard

The Open Journal of Occupational Therapy

Sensory functions decline with age, and the likelihood of having multiple sensory impairments increases with age, potentially leading to decreased physical activity and performance, decreased social participation, poorer quality of life, and greater health care spending. Presbyvestibulopathy (PVP), a diagnosis established in 2019, is a vestibular dysfunction or loss related to the aging process characterized by mild bilateral vestibular deficits, chronic dizziness, unsteadiness, gait disturbance, and/or recurrent falls. Given the potential impact of vestibular dysfunction on occupational performance and participation in meaningful activities, occupational therapy’s (OT) role in PVP is evident; however, limited literature exists specific to OT and vestibular …

Association Of Fall-Related Injuries And Different Diagnoses In Older Adults Of Ontario: A Machine Learning Approach, Sorour Rostampour

Electronic Thesis and Dissertation Repository

Falls are the leading cause of injury-related hospitalizations among older adults in Canada. This study aimed to identify the most informative diagnostic categories associated with fall-related injuries (FRIs) using three machine learning algorithms: decision tree, random forest, and extreme gradient boosting tree (XGBoost). Secondary data from two Ontario health administrative databases (NACRS, DAD) covering the period 2006-2015 were analyzed. Older adults (aged ≥ 65 years) who sought treatment for FRIs in emergency departments (ED) or hospitals, as indicated by Canadian version of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10-CA) codes for falls …

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 …

Comparison Of 360° Turn Cycles Among Individuals After Stroke And Healthy Older Adults, Rahul Soangra, Vennila Krishnan, Joby John, Ehsan Rashedi, Alison Mckenzie

Physical Therapy Faculty Articles and Research

Stroke survivors are at high risk of falling during turning. The kinematics of performing a 360° turn have not been fully analyzed among individuals after stroke. Quantitative differences in the parameters of turning between healthy older adults and those after stroke could provide detailed information on turning ability among these groups. The purpose of the current study was to characterize differences between healthy older adults and adults after stroke in 360° turn kinematics. Fourteen individuals with chronic stroke (mean age: 69 ± 8.4 years) and 14 healthy older adults (mean age: 74 ± 8.7 years) performed three trials of 360° …

Identification Of Functional Parameters For The Classification Of Older Female Fallers And Prediction Of ‘First-Time’ Fallers, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Falls remain a challenge for ageing societies. Strong evidence indicates that a previous fall is the strongest single screening indicator for a subsequent fall and the need for assessing fall risk without accounting for fall history is therefore imperative. Testing in three functional domains (using a total 92 measures) were completed in 84 older women (60–85 years of age), including muscular control, standing balance, and mean and variability of gait. Participants were retrospectively classified as fallers (n = 38) or non-fallers (n = 42) and additionally in a prospective manner to identify first-time fallers (FTFs) (n = 6) within a …

Classifying Lower Extremity Muscle Fatigue During Walking Using Machine Learning And Inertial Sensors, Jian Zhang, Thurmon Lockhart, Rahul Soangra

Physical Therapy Faculty Articles and Research

Fatigue in lower extremity musculature is associated with decline in postural stability, motor performance and alters normal walking patterns in human subjects. Automated recognition of lower extremity muscle fatigue condition may be advantageous in early detection of fall and injury risks. Supervised machine learning methods such as Support Vector Machines (SVM) have been previously used for classifying healthy and pathological gait patterns and also for separating old and young gait patterns. In this study we explore the classification potential of SVM in recognition of gait patterns utilizing an inertial measurement unit associated with lower extremity muscular fatigue. Both kinematic and …

Causes Of Post Stroke Falls Along The Care Continuum: Implications For Improving Patient Safety, Mona Madady

Electronic Thesis and Dissertation Repository

In Western countries stroke is responsible for 10-12% of all deaths. In 2000, strokes cost $3.6 billion for the Canadian healthcare system and lost productivity due to premature death and long-term disability. Falls are a frequent occurrence at all stages of post-stroke recovery and can have significant negative impacts. While information about the incidence and risk factors of falling among stroke survivors is available, considerably less is known about the specific factors contributing to falls and the circumstances surrounding these adverse events. The purpose of this project was to identify similarities between systemic factors of falls in stroke survivors across …

Determinants Of Balance Confidence In Community-Dwelling Elderly People, Janine Hatch, Kathleen M. Gill-Body, Leslie G. Portney

All PTHMS Faculty Publications

Background and Purpose. The fear of falling can have detrimental effects on physical function in the elderly population, but the relationship between a persons' confidence in the ability to maintain balance and actual balance ability and functional mobility is not known. The extent to which balance confidence can be explained by balance performance, functional mobility, and sociodemographic, psychosocial, and health-related factors was the focus of this study.

Subjects. The subjects were 50 community-dwelling elderly people, aged 65 to 95 years (X̄=81.7, SD=6.7).

Methods. Balance was measured using the Berg Balance Scale. Functional mobility was measured using the Timed Up & …
