Standing Balance And Spatiotemporal Aspects Of Gait Are Impaired Upon Nocturnal Awakening In Healthy Late Middle-Aged And Older Adults, Amanda L. Mcbean, Raymond P. Najjar, Ronald A. Schuchard, Courtney D. Hall, Cheng-Ann Wang, Ban Ku, Joseph M. Furman

ETSU Faculty Works

Study Objectives: Nocturnal awakenings may constitute a unique risk for falls among older adults. We describe differences in gait and balance between presleep and midsleep testing, and whether changes in the lighting environment during the midsleep testing further affect gait and balance.

Methods: Twenty-one healthy, late middle-aged and older (64.7 ± 8.0 y) adults participated in this repeated-measures design consisting of four overnight laboratory stays. Each night, participants completed baseline visual acuity, gait, and balance testing. After a 2-h sleep opportunity, they were awakened for 13 min into one of four lighting conditions: very dim white light (< 0.5 lux); dim white light (∼28.0 lux); dim orange light (∼28.0 lux); and white room-level light (∼200 lux). During this awakening, participants completed the same sequence of testing as at baseline.

Results: Low-contrast …

Investigating The Relationship Between Vascular Health, Gait, And Cognition In Community-Dwelling Older Adults Without Dementia, Michael A. Gregory

Electronic Thesis and Dissertation Repository

Cardiovascular disease (CVD) risk factors contribute to neuropathological changes within regions of the brain that are involved with both cognitive and motor control processes, and have been identified as potentially modifiable dementia and gait dysfunction risk factors. Exercise training is a corner-stone treatment for vascular risk factor control, and evidence suggests that physical and cognitive training can benefit cognition and gait; however, the exercise training modality that can provide the greatest cognitive benefit remains elusive. Therefore, the purpose of this thesis was three-fold: (i) to determine whether CVD risk factors and gait were associated with cognitive functioning, (ii) to determine …

Spatiotemporal Gait Pattern In Children With And Without Down Syndrome While Walking From Level Surface To Stairs, Huaqing Liang, Xiang Ke, Jianhua Wu

Physical Therapy Faculty Research

Children with Down syndrome (DS) display a delayed motor development, and show clumsy and less coordinated gait pattern. Compared to typically developing children (TD), children with DS walk with a notably slower speed, a shorter stride length, a limited range of motion in ankle joint with increased plantar flexion, and reduced dorsal flexion throughout the gait cycle. When negotiating an obstacle, children with DS show shorter stride length and greater step length variability, and stop in front of the obstacle before stepping over it.

Mobility Of Individuals With Multiple Sclerosis And The Influence Of Physical Therapy, Brenda L. Davies

Theses & Dissertations

One main purpose was to explore the compensatory gait strategies of individuals with multiple sclerosis (MS). To address this purpose, we quantified the mechanical work generated by the lower extremity joints during walking. The outcomes from this investi­gation suggested that individuals with MS redistribute positive mechanical work during walking to the hip in order to compensate for a reduced ability of the ankle to generate positive mechanical work. Additionally, we also explored the motor control of the ankle as a potential contributing factor to the mobility limitations of individuals with MS. The outcomes from this investigation indicated that individuals with …

Influence Of Visual Feedback On Dynamic Balance Control In Chronic Stroke Survivors, Eric R. Walker, Allison S. Hyngstrom, Brian D. Schmit

Physical Therapy Faculty Research and Publications

Chronic stroke survivors have an increased incidence of falls during walking, suggesting changes in dynamic balance control post-stroke. Despite this increased incidence of falls during walking, balance control is often studied only in standing. The purpose of this study was to quantify deficits in dynamic balance control during walking, and to evaluate the influence of visual feedback on this control in stroke survivors. Ten individuals with chronic stroke, and ten neurologically intact individuals participated in this study. Walking performance was assessed while participants walked on an instrumented split-belt treadmill with different types of visual feedback. Dynamic balance control was quantified …

Effects Of Chemotherapy-Induced-Peripheral-Neuropathy On Spatiotemporal Gait Parameters And Fall Risk In Cancer Patients After The Completion Of Chemotherapy Drug Treatment, Timothy F. Marshall

Seton Hall University Dissertations and Theses (ETDs)

Background: Cancer patients undergoing chemotherapy often experience chemotherapy-induced-peripheral-neuropathy, which reportedly causes gait disturbances that may increase their risk for falls. Falls are a significant event because they have been linked to serious injuries and disabilities, loss of independence, and increased mortality rates. Purpose: The purpose of this study was to assess whether chemotherapy-induced peripheral neuropathy is associated with spatiotemporal gait adaptations in posttreatment adult cancer survivors when compared to healthy, disease-free, age and morphologically matched controls. Methods: In a quasi-experimental design, 16 subjects participated in the present study. There were 8 CIPN subjects between the ages of 50–70 years of …

The Effect Of Thermacare Heat Wraps On Balance And Mobility In Seniors With Impaired Gait - A Cross Over Study, Jerrold S. Petrofsky, Michael S. Laymon, Iman Akef Khowailed, Haneul Lee

College of Health & Human Services (TUN) Publications and Research

To examine if the use of heat at home can result in better quality and safer mobility in the elderly with gait and balance impairments.

Setting: Randomized longitudinal cross over study design in a clinical setting.

Methods: 20 people with impaired mobility (assessed as a score of more than 4 on the Stepping On questionnaire) were tested with a multi-camera gait analysis system, a treadmill with pressure sensors, a balance platform and the timed up and go and walking speed tests before and after using ThermaCare continuous heat wraps on their legs and knees for 6 days at 4 hours …

Stepping On: Gait Velocity And Fall Risk Assessment, Brittney Herbst

Physical Therapy Scholarly Projects

Purpose: To identify fall risk and determine if the Stepping On program is effective at reducing the risk of falls in participants by increasing gait speed to greater than or equal to 1 m/s. Step and stride length were also compared to age related norms to determine if they correlated to fall risk. Gait speed of less than I m/s has been shown to increase the risk for falls in elderly.

Methods: Fourteen female participants over the age of 65 (mean age of 87) were recruited from a local Stepping On class conducted at an assisted living facility …
