Effects Of Functional Electrical Stimulation Cycling Versus Cycling Only On Walking Performance And Quality Of Life In Individuals With Multiple Sclerosis: A Randomized, Clinical Pilot Study, Lori Hochman

Department of Physical Therapy Student Theses, Dissertations and Capstones

Background: Functional Electrical Stimulation (FES) stimulates peripheral nerves via electrical current to evoke muscle contractions and when combined with lower extremity cycling (LE), creates patterned leg movements. Previous studies demonstrated FES cycling is safe and effective in the spinal cord injury and stroke populations with improvements seen in walking speed, muscle mass, and bone density. Few studies have applied FES cycling to a neurodegenerative disorder, such as multiple sclerosis (MS). The aim of this study is to assess the effect of an 8-week training program using FES cycling, compared to Cycling Only, in people with MS (PWMS). Methods: Using a …

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

Courtney D. Hall

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 …

The Attentional Demands Of Ambulating With An Assistive Device In Older Adults With Alzheimer's Disease, Susan W. Hunter, M Montero-Odasso

Physical Therapy Publications

Ambulation with a mobility aid is a unique real-life situation of multi-tasking. These simultaneous motor tasks place increased demands on executive function in healthy young and older adults, but the demands have not been evaluated in people with Alzheimer's disease (AD). Mobility problems are common among adults with AD, leading to provision of a mobility aid to optimize independent activity. The study objectives were: (i) to determine the dual-task cost (DTC) associated with the use of a mobility aid in straight and complex path walking, and (ii) to evaluate the association between executive function and ambulation with a mobility aid …

The Effects Of Fatigue On Balance In Individuals With Parkinson's Disease: Influence Of Medication And Brain-Derived Neurotrophic Factor Genotype, Michael Baer, Bradley Klemetson, Diana Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: The purpose was to investigate the effects of fatigue on balance in individuals with Parkinson’s disease (PD). Because falls in this population can have deleterious consequences, it is important to understand the influence of fatigue and PD medications on balance. Additionally, since brain-derived neurotrophic factor (BDNF) has been shown to be related to motor performance, we explored its role in balance fatigue. Participants: 27 individuals (age= 65.4±8.1; males= 14, females= 13) with neurologist-diagnosed PD. Of the 27, 13 were genotyped for BDNF as Val/Val, 11 as Val/Met, 2 as Met/Met, and one refused genotyping. Methods: Participants were …

Visual, Verbal, And Tactile Cues On Improving Gait In A 71-Year Old Male With Dementia Of The Lewy Bodies, Symone Carter, Jackie Crossen-Sills

St. Augustine, Spring 2017

The purpose of the case report is to demonstrate how visual, verbal, and tactile cues can improve gait in a patient with DLB.

Longitudinal Adaptations In Muscle Strength, Functional Performance, Gait Biomechanics, And Patient-Reported Function After Unilateral Total Knee Arthroplasty, Paul W. Kline

Theses and Dissertations--Rehabilitation Sciences

Objective: The aims of this research were to identify gaps in the literature related to impairments after total knee arthroplasty (TKA) (Aim 1) and define recovery between 3 and 6 months after TKA across four domains: 1) hip and knee muscle performance, 2) functional performance, 3) patient-reported function, and 4) biomechanics of walking and stair descent (Aim 2). Additionally, this project sought to explore the relationships between each domain (Aim 3) and establish predictive models to allow clinicians to use clinical measures to predict future gait biomechanics in patients after TKA (Aim 4). Ultimately, the results of this research would …

Altering A Runner’S Foot Strike Using A Modified Elliptical Trainer, Daniel Shull

Theses and Dissertations

One possible solution to common running related injuries is to transition runners from a rearfoot strike during initial contact to a midfoot strike. Natural rearfoot strike runners were studied to see if a modified elliptical trainer could be used to alter their running pattern to that of a midfoot strike runner. Their results were compared to subjects who ran on a non-modified elliptical trainer. After training on the modified elliptical trainer, subjects demonstrated a decrease in foot angle at initial contact when attempting to run with a midfoot strike. Training did not affect all kinetic metrics or stride frequency. However, …
