Age-Related Modifications To The Magnitude And Periodicity Of Neuromuscular Noise, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Background: Evaluation of task related outcomes within geriatric and fall-prone populations is essential not only for identification of neuromuscular deficits, but also for effective implementation of fall prevention strategies. As most tasks and activities of daily living are performed at submaximal force levels, restoration of muscle strength often does not produce the expected benefit in functional capacity. However, it is known that muscular control plays a key role in the performance of functional tasks, but it remains unclear to what degree muscular control and the associated neuromuscular noise (NmN) is age-related, particularly in the lower-extremities.

Grip Strength, Multimorbidity, And Disability, Amy M. Yorke

Dissertations

The presence of two or more chronic health conditions, also known as multimorbidity, is one of the most prevalent health disorders experienced by adults. Adults with multimorbidity and functional limitations represent clinical and financial challenges to the current health care system. The purpose of this three-paper dissertation is to examine the relationship between grip strength, multimorbidity, and the prediction of disability in adults. Data from the 2008 Health and Retirement Study (HRS), a nationally representative, longitudinal study completed on Americans age 50 years and over, are used for the dissertation.

The objective of the first paper is to investigate the …

An Examination Of Executive Function, Mild Cognitive Impairment And Fall Risk In Community Dwelling Older Adults, Jennifer A. Blackwood

Dissertations

The aim of this three-paper dissertation was to examine the relationship between fall risk, executive function (EF) and mild cognitive impairment (MCI) in community dwelling older adults. Papers one and two describe how mild changes in cognition influence performance on four measures of fall risk, the Five Times Sit to Stand Test (FTSTS), usual gait speed, the Timed Up and Go (TUG) test, and the Activities Specific Balance Confidence Scale (ABC) in a group of community dwelling older adults. The third paper describes if participation in a progressively challenging domain specific computerized cognitive training intervention influenced performance on measures of …

Pilot Comparative Effectiveness Study Of Surface Perturbation Treadmill Training To Prevent Falls In Older Adults, Jon D. Lurie, Alexandra B. Zagaria, Dawna M. Pidgeon, Judith L. Forman, Kevin Spratt

Dartmouth Scholarship

Falls are the leading cause of fatal and non-fatal injuries among older adults. Exercise programs appear to reduce fall risk, but the optimal type, frequency, and duration of exercise is unknown. External perturbations such as tripping and slipping are a major contributor to falls, and task-specific perturbation training to enhance dynamic stability has emerged as a promising approach to modifying fall risk. The purpose of this pilot study was 1) to determine the feasibility of conducting a large pragmatic randomized trial comparing a multidimensional exercise program inclusive of the surface perturbation treadmill training (SPTT) to multidimensional exercise alone (Standard PT); …

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 …

Functional Improvement In Older Adults After A Falls Prevention Pilot Study, Pei-Fen J. Chang, Yong-Fang Kuo

The Open Journal of Occupational Therapy

Falls are a costly, disabling, and life-threatening risk in the elderly. Improvements in physical function, balance, lower extremity strength, and health-related quality of life are hypothesized to help mitigate fall risk. In this pilot study, six women and men with an average age of 81 years participated in a 6-week exercise and education program created to reduce risk of falls. Evaluations were made at baseline and at 6 weeks on four tests: the Functional Status Questionnaire, the Berg Balance Scale (BBS), the Six-minute Walk Test, and the World Health Organization Quality of Life–BREF 26-question test. Scores indicated significant improvement in …

Extreme Levels Of Noise Constitute A Key Neuromuscular Deficit In The Elderly, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Fluctuations during isometric force production tasks occur due to the inability of musculature to generate purely constant submaximal forces and are considered to be an estimation of neuromuscular noise. The human sensori-motor system regulates complex interactions between multiple afferent and efferent systems, which results in variability during functional task performance. Since muscles are the only active component of the motor system, it therefore seems reasonable that neuromuscular noise plays a key role in governing variability during both standing and walking. Seventy elderly women (including 34 fallers) performed multiple repetitions of isometric force production, quiet standing and walking tasks. No relationship …

Use Of The Term "Elderly", Dale Avers, Marybeth Brown, Kevin Chui, Rita A. Wong, Michelle M. Lusardi

Using the term elderly for a person who is robust and independent as well as for a person who is frail and dependent says little about the individual.

Are Scores On The Ppt Useful In Determination Of Risk Of Future Falls In Individuals With Dementia?, Mary K. Farrell, Richard A. Rutt, Michelle M. Lusardi, Ann K. Williams

All PTHMS Faculty Publications

Individuals with dementia or Alzheimer’s disease (AD), exhibit both a progressive decline in cognitive function and accumulating difficulty with physical function.¹ As cognitive impairment begins, individuals will initially demonstrate difficulties with short-term memory and with instrumental activities of daily living. As the dementia progresses, individuals will increasingly demonstrate difficulties with long-term memory, communication, and basic activities of daily living.

Residency Corner, Tamara Gravano

Physical Therapy Faculty Research

The new Residency Corner will feature articles written by residents that describe topics such as in-depth case analysis, problem solving, and practice as nonphysician primary care providers. Here residents will get to discuss their findings and thought-processes with an audience of their peers--those clinicians and academics interested in the advancement of geriatric health care. Also, for those who may be interested to see what geriatric residency education is really all about, these clinical snapshots can help remove the veil and provide a glimpse into the level of practice our residents are experiencing. Yet, this is only one half of the …

White Paper: Walking Speed: The Sixth Vital Sign, Stacy Fritz, Michelle M. Lusardi

All PTHMS Faculty Publications

Walking speed is "almost the perfect measure." This review summarizes the strong psychometric properties of walking speed and robust evidence for using this clinical measurement. Walking speed is easily measurable, clinically interpretable, and a potentially modifiable risk factor. For these reasons, using WS as the sixth vital sign is both pragmatic and essential.

Response Of Endothelial Cells To Stressors: The Impact Of Aging And Diabetes, Katie Mclellan

Loma Linda University Electronic Theses, Dissertations & Projects

Preliminary research indicates there is some impairment of the endothelial cells to respond to single stressors such as local heat, shear stress, and global heat in older people and people who have diabetes. The response of the skin blood flow to local heat is an indicator of the endothelial cells ability to cope with stress. In addition, factors such as thicker subcutaneous fat and skin moisture may impair the skin’s ability to dissipate heat. For older people and people with diabetes, this endothelial dysfunction may cause an even more diminished response to multiple stressors. However, no studies have examined the …

Physical Therapy Faculty Research

The Geriatric Residency in Physical Therapy program at St. Catherine's Rehabilitation Hospital and Villa Maria Nursing Center has graduated 4 residents since its inception in 2003. Recently, the 4 of us program graduates convened to talk about our experiences and discovered several similarities. We laearned about our individual reasons for choosing the residency, our experiences during the time we were residents, and our plans for continued professional development. But, of course, there were some differences that made the experience unique for each of us.

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 & …
